Blood Clot Treatments
Anticoagulants: Treatment of Blood Clots
Anticoagulant medications (blood thinners).
Doctors use anticoagulants or blood thinners to treat blood clots. These medications slow the time it takes for blood to clot. They also prevent clots from growing. Blood thinners also prevent more clots from forming in most patients. The most common blood thinners used today are heparin, low molecular weight heparin, and warfarin.
But be very careful about the side effects of these drugs!
Monitoring heparin with daily blood testing.
If you take heparin, you will have a blood test every day to see if you are taking the right dose. This blood test is called a UF heparin level or anti-Xa level. The doctor will adjust your heparin dose based on the results of these blood test. Your blood levels can change. That is why you need frequent monitoring.
Advantages of heparin:
• UF heparin does not cost a lot.
• UF heparin gets into the blood quickly.
• UF heparin works quickly to prevent your blood from forming blood clots.
• The effect of UF heparin wears off quickly when the IV drip is stopped.
Disadvantages of UF heparin.
• UF Heparin requires frequent blood tests to check how well the heparin is working to prevent your blood from clotting.
• If you need to take UF heparin in your vein or by IV, you will need to be hospitalized.
• To treat a new clot the doctor will put you in the hospital for 3-10 days.
Side effects of UF heparin.
The side effects of UF heparin include:
o Bleeding (most serious side effect)
o Skin rash
o Headache
o Cold symptoms
o Stomach upset
o Loss of bone strengthA rare side effect of UF heparin is a condition called Heparin Induced Thrombocytopenia (HIT).
• Less common
• May occur if you are on heparin for long periods of time, like several months
o HIT is sometimes incorrectly called “heparin allergy.”
o It occurs in a small number of patients.
o It is very serious.
o Symptoms include
o Increased clotting or developing new clots while on heparin,
o Which can lead to:
• Deep vein thrombosis (DVT) or a clot in the leg or arm;
• Pulmonary embolism or a blot clot in the lungs, or
• Death.
LOW MOLECULAR WEIGHT HEPARIN (LMWH)
Low molecular weight heparin are like heparin, but you can take them at home by giving yourself an injection or shot under the skin. They last longer in your body than UF heparin. The effect of LMWH is more predictable than UF heparin, so most patients do not need monitoring.
Names of LMWH.
The LMWH available in the United State are:
• dalteparin (Fragmin®) and
• enoxaparin (Lovenox®)
Advantages of LMWH.
• LMWH is given by injection under the skin rather than by IV, so you can treat yourself at home more easily.
• LMWH eliminates or reduces the time you need to spend in the hospital to treat a clot.
• If you take LMWH, you usually do not have to have blood tests to monitor it.
Disadvantages of LMWH.
• LMWH is expensive.
• The side effects of LMWH are very similar to heparin; However, HIT and loss of bone strength are much less common than with heparin.
WARFARIN
• Warfarin (Coumadin®) is a pill for long-term anticoagulation or blood thinning.
• You usually take heparin (UF heparin or LMWH) for the short-term.
• The doctor adds warfarin with the heparin (UF heparin or LMWH heparin) so you take both medicines for a few days.
• The warfarin must reach a certain level in your blood to work.
• You may have to take warfarin 5-7 days (or longer) with the heparin (UF heparin or LMWH heparin) for the warfarin to reach an adequate level in your blood to work.
• Once your warfarin dose is sufficient, the doctor will stop your heparin (UF heparin or LMWH heparin) and you can go home from the hospital.
Advantages of warfarin.
• Warfarin is inexpensive.
• Warfarin is a pill.
• Warfarin is familiar to doctors because it has been used to treat patients since the 1950’s.
Disadvantages of warfarin.
• If you take Warfarin, the most serious side effect is bleeding because Warfarin lengthens the time it takes for blood to clot.
• You may experience the following side effects:
o Headache (rare)
o Rash
o Hair loss
o Skin breakdown
o Purple toes
o Elevated liver enzymes
• You should discuss any side effects or unusual symptoms with your healthcare provider as soon as you notice them.
• Sometimes these side effects go away by themselves.
• If the side effects do not go away, your doctor may prescribe a different blood thinner.
Monitoring warfarin with regular blood tests.
• The blood test that monitors warfarin is called an INR (international normalized ratio).
o The INR measures how long it takes blood to clot.
o It standardizes results of prothrombin time, protime, or clotting time (names for different types of tests used in different labs).
o Most patients on warfarin do best with an INR between 2.0 and 3.0, considered the ideal or “therapeutic range.”
o A higher or lower INR range may be appropriate for certain patients.
• Warfarin requires frequent monitoring (INR), especially in when you start taking it.
• Once your INR is stable you can have your blood tests about once a month to monitor.
• INR can be measured by going to the lab and having a blood test, or by a finger stick test that can be performed in a clinic or at home with an INR a self-monitoring device.
o Home INR testing requires patients meet certain requirements
o Home INR testing can be expensive
• INR too low? If an INR is below the ideal or therapeutic range, the risk of clotting is higher.
• INR too high? If an INR is above the therapeutic range, the risk of bleeding is higher.
Tips for taking warfarin.
• Same time each day.
o You should take warfarin the same time every day.
o The evening is the best time to take warfarin because you can change the dose the day of the INR if needed.
o If the evening is not a convenient time, take it at the same time each day that fits your schedule, or with the same task each day that will help you remember.
• Missed Doses.
o If you miss a dose of warfarin, you have an 8-hour window when it is still safe to take it.
o If you skip your dose and more than 8 hours goes by, contact your doctor right away.
• Warfarin and alcohol.
o Drinking a light or moderate amount of alcohol (1-2 glasses of wine or 1-2 beers per day) usually does not influence the INR.
o However, drinking a large amount can affect warfarin and increase your risk for bleeding.
• Warfarin and food.
o Food high in vitamin K, like green leafy vegetables can affect the amount of warfarin you need to take.
o You must keep a consistent diet of foods high in vitamin K such as green leafy vegetables, since if you change the amount of vitamin K you eat, it affects your INR levels.
Effect of other prescribed or over-the-counter medications on warfarin.
• ANYTIME you start or stop a medicine – even if it is something you bought over the counter – you should tell your doctor, nurse or pharmacist right away because they may want to start checking your warfarin level more frequently.
• Tell your doctor, nurse, or pharmacist about all the medications you take. This includes prescription drugs, over the counter ones, and vitamins, herbals and supplements.
• Some medications, especially antibiotics, can change your INR reading.
• Over-the-counter anti-inflammatory medications (such as aspirin, ibuprofen, naprosen, goody’s powder) may increase your risk of bleeding.
• You can usually take acetaminophen (Tylenol®). Tell your doctor if you take acetaminophen more than once a day or for longer than a week.
New Anticoagulant or Anti-Clotting Medications
Several new anticoagulants (blood thinners) medications have recently been approved by the United States Food & Drug Administration (FDA).
Approved (in US) to treat prevent blood clots that can cause strokes in people who have atrial fibrillation or AFib:
• Apixaban (Eliquis®)
• Dabigatran (Pradaxa®), and
• Rivaroxaban (Xarelto®)
Approved (in US) to treat deep veins thrombosis (leg or arm clot or DVT) & pulmonary embolism (lung clot or PE)
• Rivaroxaban (Xarelto®)
• Apixaban (Eliquis®) – Approved for prevention of DVTs/PEs following hip and knee replacement surgery as of March 14, 2014.
• Dabigatran (Pradaxa®) – Approved for for the treatment of deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients who have been treated with a parenteral anticoagulant for 5 to 10 days, and to reduce the risk of recurrent DVT and PE in patients who have been previously treated as of April 7, 2014.
Other medications are being reviewed for approval from the FDA and may be available within the next year
Facts about these newer medications: They
• Do not require frequent lab monitoring
• Have less drug/herbal interactions
• Require dietary restrictions
• Have less fatal bleeding events
• Are expensive
• Do not have antidotes meaning their anti-clotting properties are not easily reversible – may require transfusion with clotting factor
• Take effect quickly and do not require overlapping with heparin
• Effects wear off quickly
• May be eliminated through the kidneys or live
Reduce Your Risk Of Blood Clots Without A Prescription
One of the the facts I emphasize during my integrative oncology talks is that the majority of patients with cancer do not die from their cancer, but instead from a side effect or complication related to their cancer or the cancer treatment.
• FACT: One in five cancer patients will develop a potentially life threatening blood clot within their first year of their diagnosis (and up to 50% by the time of death.)
This blood clot is called a DVT (deep vein thrombosis.) Typically, they develop in the veins of the arm, leg or pelvis, and they can present with swelling, pain, redness, warmth, or heaviness in the affected area.
If they dislodge and travel to the lung, heart or brain, they can become deadly. A VTE (venous thromboembolism) is the term used for any DVT that ends up in another part of the body.
• The most well known VTE is a PE (pulmonary embolism), a DVT that gets stuck in the veins of the lung and blocks critical blood flow to lung. This can present with shortness of breath, cough or chest pain. Without rapid diagnosis and treatment it can be fatal.
The increased risk of blood clots and cancer is not recent news…it’s been known since 1865!
It’s hard for me to imagine, but one study reported that more than one-quarter of oncologists believe cancer patients are not at increased risk for blood clots.
Who Is At Greatest Risk Of Developing A Blood Clot?
DVT’s occur much more commonly among those with certain risk factors:
• Having Cancer (some cancers are more associated with blood clots)
• Recent major surgery or trauma
• Having a central venous catheter
• Receiving drugs that increase the risk of blood clots (i.e. hormonal therapy, numerous chemotherapy drugs, white and red blood cell growth factors)Being obese or overweight
o Are you on Tamoxifen? Read our prior blog post about a simple blood test that detect if you are at a high risk of blood clots.
• Physical inactivity (read about Physical Activity and Cancer on our prior blog post)History of a prior stroke (or transient ischemic attack, TIA)
o prolonged hospitalization or bedrest are notorious risk factors…but even short periods (i.e. a few hours) of inactivity can increase your risk
• History of a heart attack or coronary artery disease (read about Cardiac Complications After Cancer on our prior blog post)
• History of a prior blood clot (or family history of blood clots)
• High blood pressure
• Smoking
• Having atrial fibrillation (and abnormal heart rhythm)
• High LDL and total cholesterol levels and/or low HDL levels (known risk factors for the development of atherosclerosis: clots often form in areas of arterial plaques on blood vessel walls)
• Having a low red blood cell count (anemia), having a high platelet count or having a high white blood cell count
• Elevated levels of homocysteine or high-sensitivity C-reactive protein (hsCRP)
• High blood sugar levels
• Drinking more than 1 serving of alcohol per day
• …and a variety of other conditions (i.e. thyroid abnormalities, pregnancy, high blood fibrinogen levels)
Deep vein thrombosis (DVT) in the leg on the left.
• Risk factor assessment model (for those with a diagnosis of cancer)
• PreventDVT.org risk calculator (for those with or without a diagnosis of cancer)
How Does Cancer Increase The Risk Of Blood Clots?
• Cancer cells produce blood clotting and inflammatory proteins that make the blood more likely to clot.
• Numerous medications used to treat cancer can increase the risk of blood clots.
• As a result of cancer or cancer treatment, many patients get out of shape, or have pain or limitations in their range of motion. This can lead to physical inactivity, increased obesity and systemic inflammation…all known risk factors for developing blood clots.
o A recent surgery or hospitalization is the most common risk factor for developing DVT’s (typically as a consequence of prolonged inactivity leading to pooling of blood in the legs and pelvis.
o When your legs remain still for long periods, your calf muscles don’t contract, which normally helps blood circulate. Blood clots can form in the calves of your legs if your calf muscles aren’t moving.
Here Are My Recommendations To Help Reduce The Risk Of Blood Clots:
• Increase physical activity:Maintain a healthy weight
o Exercise your legs frequently while you’re sitting
o Exercise regularly (goal: at least 30 minutes of moderate aerobic exercise, 5-days per week)
o Get up and walk around every 2 to 3 hours
• Stop smoking! (and avoid second-hand exposure)
• Reduce stress (read how stress increases inflammation on our prior blog post)
• Limit alcohol consumption to 1 serving per day (preferably red wine)
• Consume an anti-cancer/anti-inflammatory diet
• Consider taking a daily, low-dose (“baby aspirin”):
o Recent studies have reported that individuals who take a low-dose aspirin every day may reduce their risk of blood clots by 40%.
o Read our prior blog post on how taking “One Baby Aspirin Per Day Cuts Cancer Development, Metastases and Death!“
• The active ingredient in aspirin is a plant-derived compound called a “salicylate.” Instead of taking a baby aspirin, you could simply consume foods that have high salicylate content (as well as many anti-cancer and anti-inflammatory phytonutrients):
o Fruits: apricots, oranges, blackberries, pineapple, blackcurrant, plums, blueberries, prunes, raspberries, strawberries, grapes, cranberries, tangerines, tomatoes
o Spices, herbs and others: curry, cayenne, paprika, thyme, turmeric, ginger, dandelion, gingko, licorice and peppermint, wine, vinegar, honey, cider
• Consume foods that are rich in vitamin E or omega-3 fatty acids (both of which have blood thinning properties and may reduce the risk of blood clots):
o Sources of omega-3 fatty acids include:
• Fatty fish (i.e. anchovies, salmon, lake trout, herring, mackerel) and fish oil
• Plant sources (i.e. flaxseed, sunflower seeds, canola oil, corn oil, safflower oil, soy)
o Vitamin E rich foods include:
• Nuts (i.e. walnuts, almonds, hazelnuts)
• Vegetable oils (i.e. canola oil, sunflower oil, palm oil)
• Lentils (i.e. chickpeas)
• Oats and wheat
• Other foods and supplements that reduce blood clotting:
o Curcumin
o Polyphenol-rich foods
o Vitamin C
o Nattokinase (a compound produced during soy fermentation; found only in natto, which smells like very dirt socks, so unless you can stomach that scent I suggest taking nattokinase supplements)
o Garlic
o Gingko biloba

Natural Remedies to Help Blood Clots
Last Modified on Nov 11, 2014
Home > Ailments > Natural Remedies to Help Blood Clots
While your blood naturally clots to stop bleeding when you get an injury, this property of your blood can also lead to health issues, such as a blood clot. You can reduce your chance of getting blood clots and even treat existing clots naturally, though. Apple cider vinegar, blackstrap molasses, and cayenne pepper are three of the most effective natural treatment options for blood clots.
What Is a Blood Clot?
A blood clot is a buildup of blood and tissue inside one of your veins or arteries. These blockages can block blood flow to important organs or can even travel to your lungs, heart, or brain and cause an embolism or other severe health condition.
Blood clots typically present specific symptoms that help indicate an issue. Some of the most common symptoms include pain at the site of the clot, tenderness, swelling, or even a blue-colored bulge. Some individuals even experience difficulty breathing (associated with a Pulmonary Embolism) or ulcers.
What Are the Best Natural Remedies for Treating Blood Clots?
It is important to maintain appropriate doctor supervision when dealing with issues such as blood clots to prevent more progressive problems. Nonetheless, many natural remedies help promote healthy blood flow and effectively treat blood clots. Apple cider vinegar, blackstrap molasses, and cayenne are three of the best home remedies for blood clots.
1. Apple Cider Vinegar
Among its various other components, apple cider vinegar is a natural blood thinner. With this capability, ACV helps to break down clots in your blood and promote better blood flow throughout your body. To utilize this treatment option, drink a tonic of 2-3 tablespoons of apple cider vinegar diluted in 8 ounces of water at least once a day.
2. Blackstrap Molasses
Blackstrap molasses contains a number of nutrients that fortify your blood, including iron. Used as a treatment for blood clots, blackstrap molasses increases blood flow and helps break down clogged arteries and regular blood clots. Take 1 to 2 tablespoons of molasses a day for the best benefits.
3. Cayenne
Cayenne contains a number of important nutritional components including capsaicin, flavonoids, volatile oils, and steroid saponins. These compounds help cayenne increase your bloods hypocoagulability, meaning your blood is less able to coagulate or clot. In addition to reducing blood coagulation, cayenne also increases circulation, which helps dissolve blood clots and improve blood flow. To employ this remedy, make cayenne tea by pouring one cup of boiling water into 1/4 teaspoon of cayenne pepper and drink the tea daily.

Foods that Thin the Blood Naturally
Read my disclaimer and terms of use.
Overview
There are a number of foods and supplements that are known to thin the blood. These include foods with high amounts of aspirin-like substances called salicylates, omega-3 fatty acids, vitamin E supplements, and foods with natural antibiotic properties.
Strawberries contain a very high amount of naturally occurring salicylates.
While many Americans have problems with blood clots, it is important to note that blood thinning foods are not desirable for everyone in the population. I have been an easy bleeder all of my life, so I have compiled this list so that I know which foods to limit, in order to keep my blood from being too thin.
People taking prescription anti-coagulant drugs also need to be careful not to consume too many foods with natural blood thinning compounds in addition to their regular medication. One of my relatives is on a prescription anticoagulant drug for blood clots and has had eye hemorrhages from ingesting too many blood thinning foods in conjunction with his prescription medication.
Interestingly, my relative was given a list of foods high in vitamin K so he would know what foods to limit so as not to reduce the effectiveness of his medication. However he was not given a list of foods that have their own anticoagulant properties, which if taken in conjunction with his medication could cause bleeding problems. He found some information on his own about blood thinning foods after he had the two eye hemorrhages.
Blood coagulation should fall within a desirable range. If it coagulates too easily, clots can form which in turn can lead to adverse health conditions such as heart attacks. If blood doesn't clot enough, conditions such as bleeding from the nose aka (nosebleeds or epistaxis), hemorrhages, hematuria (blood in the urine), heavy periods in women, and bleeding strokes may occur. If a person's blood isn't clotting enough and he has surgery or a traumatic event like a car accident, he could have a serious problem by losing too much blood from wounds or surgical incisions failing to clot properly.
Some of the foods that are generally thought to have natural blood thinning compounds are listed below. Please note that this is a hodge-podge list based on information I've collected over the years based on my own experiences, my assortment of alternative health books and internet research, so it's possible it may contain some errors. See your doctor before you implement any diet, supplement or exercise changes, especially if you are taking any prescription medications or have any health concerns related to coagulation.
Salicylates
One type of natural blood thinners are substances that block vitamin K known as salicylates. The most well known of these is aspirin, but many foods, such as preservatives and flavorings, also contain salicylates or aspirin-like substances. Some individuals are known to be aspirin or salicylate sensitive. I'm one of those salicylate sensitive types, but I have found that I can eat more salicylates as long as I eat a balanced amount of vitamin K foods. (Vitamin K plays an important role in the body's in blood clotting processes. The "K" in vitamin K gets its name from the Danish word for coagulation.)
Foods that are higher in salicylates include many spices, most fruits, especially dried fruits, nuts, and also some flavorings and preservatives.
Ginger is known as a warming spice in both Ayurvedic and Traditional Chinese Medicine.
Herbs and spices high in salicylates include:
• Curry powder
• Cayenne pepper
• Ginger
• Paprika
• Thyme
• Cinnamon
• Dill
• Oregano
• Turmeric
• Licorice
• Peppermint
In Ayurvedic (traditional Indian medicine) many of the above spices are known as "warming spices". I think this is because by thinning the blood they increase a person's blood circulation, which in turn speeds up the metabolism and makes a person feel warmer.
My family was really cold one late evening at Disneyland, but as soon as we ate some churros we all warmed up. We did not know why at the time, but later realized it was because the churros were dipped in sugar with cinnamon, a spice high in blood thinning compounds and one of the key warming spices discussed frequently in Ayurvedic medicine.
One of my children has had trouble with night sweats, so we put him on a diet that, among other changes, limited the amount of salicylates he consumed. That seemed to help him stay much cooler at night.
Fruits high in salicylates include
• Raisins
• Prunes
• Cherries
• Cranberries
• Blueberries
• Grapes
• Strawberries
• Tangerines
• Oranges
Other substances high in salicylates:
• Chewing gum
• Honey
• Peppermints
• Vinegar
• Wine
• Cider
Though there are some exceptions, in general most meat, fish, dairy, grains and vegetable foods are not high in salicylates. Many types of fish do however have blood thinning properties due to their omega-3 fatty acid content, as noted below.
Chinese food is often prepared with many warming spices, such as ginger and garlic. One morning, after having Chinese food for dinner the night before, I was barefoot in the kitchen and stepped on a sharp pieces of glass from a broken glass storage bowl. The actual cut was very small, but the amount of blood loss was quite scary. I tried applying direct pressure to the wound but that didn't help. My foot only stopped bleeding after I ate a bowl of vitamin K rich lettuce.
A 2001 study published in the European Journal of Nutrition found the salicylate content of organic foods to be higher than conventional foods. So if you are salicylate sensitive or have unexplained easy bleeding issues, you may want to experiment and see if you feel better by not eating organic foods.
Bleeding and Topical Creams
It is important to note that it isn't just what you eat that can thin your blood, but also what you rub on your skin. The New York Times reported in 2007 the death of a high school track star from an overdose of a commonly sold, over the counter sports medicine that contained methyl salicylate. Methyl salicylate at high enough doses rubbed into the skin can act as an anti-clotting agent, which in turn may result in internal bleeding and related health issues.
I've received more than one email from my web site readers who developed bleeding problems after trying to consume large amounts of ripened berries from their gardens. They were trying to use up a bumper crop of a fruit like blueberries or strawberries and inadvertently thinned their blood from the unusually high berry consumption. One person had recently had surgery and his incision didn't heal properly until he stopped eating excessive amounts of berries.
Appendix 9 in this thesis paper by Anne Swain, has a chart of salicylates in foods and an example of a low salicylate diet.
Vitamin E
Vitamin E is an antagonist to vitamin K. Some foods and topical substances these days are preserved with vitamin E, so it pays to read labels carefully. One of my sons, who otherwise has not had any unusual bleeding problems or easy bruising, developed a severe nose bleed from a hand sanitizer that had vitamin E used as a preservative. He woke up in the middle of the night one night with clots coming out of his nose, so I tried to think of what we had done differently that day as a possible cause. Then I remembered I had bought both kids a new hand sanitizing lotion at the local pharmacy, I checked the ingredients on the bottle and vitamin E was listed. So I gave him a lettuce salad to eat, which stopped the bleeding, and threw out the sanitizer. He has not had another nose bleed since that that day over ten years ago.
Foods high in vitamin E may not necessarily thin the blood, as many foods high in vitamin E, such as spinach and broccoli also contain significant amounts of vitamin K, which tends to clot the blood.
I was prescribed vitamin E supplements at one time by a doctor for fibrocystic breasts. Afterwards, I developed an increased number of bleeding and bruising problems, including menorrhagia. I did some research on my own and realized vitamin E could thin the blood. Most medical articles state that people have to take relatively large doses of vitamin E in order for it to have an effect on coagulation. However, I don't think that is true for everyone. For people like me who are easy bleeders, even small amounts of vitamin E can cause bleeding issues.
Vitamin B6?
This is just an anecdotal report based on my own experience, but I took a vitamin B6 supplement at one time and developed a really bad nose bleed shortly afterwards. The nose bleed stopped when I had a vitamin K rich salad, so I do think that the bleeding was from a lack of vitamin K and not other causes, such as trauma or high blood pressure. The vitamin B6 tablet was the only change I made in my usual diet and routine that day.
Interestingly, one of my health books noted that vitamin B6 lowers estrogen levels, and it is well established through medical studies that increased estrogen levels are linked to blood clots. As such, if vitamin B6 does lower estrogen levels, then it may make sense that it may also lower vitamin K levels and thin the blood. However, I have never found any studies noting this particular association, so at this time the link between vitamin B6 and thinner blood is just a hypothesis in my part based on information from my health books, my own experience and logical deduction.
Omega- 3 Fatty Acids
Omega-3 fatty acids have received a lot of press lately because of their ability to lower cholesterol levels and make the blood less prone to clotting. Fish oil is usually high in omega-3s and can be ingested either through purchasing capsules or by eating fatty fish. Fish with high amounts of omega-3s include:
• Anchovies
• Salmon
• Albacore tuna
• Mackerel
• Lake Trout
• Herring
A number of studies in recent years have found omega-3 fatty acids beneficial for anxiety and depression. When eating fish, one danger is that many fish have high mercury levels, so experts often have mixed recommendations on exactly just how healthy eating a lot of seafood is for most people.
The chart in this link to the U.S. Environmental Protection Agency web site contains a table of mercury levels in commercial fish and shellfish. Fish may be a great food for people who are at risk for blood clots, but for easy bleeders like me it is a food I need to limit, regardless of mercury levels.
Garlic contains nine different, naturally occurring, antiplatelet compounds.
Additional Selected Foods With Compounds That Thin the Blood
• Tree Ear
• Jicama
• Garlic
• Onions
• Olive Oil
Garlic and onions contain natural antibiotics that can kill the intestinal bacteria that manufacture vitamin K. Many studies have found that long term prescription antibiotic use can cause bleeding problems due to a vitamin K deficiency. However, for people like me who seem to always be short on vitamin K, even small amounts of foods with natural antibiotics properties, like garlic and onions, are problematic. I often avoid eating at Italian restaurants because of their liberal use of garlic. When I do eat Italian food, I also try to have have a salad with lots of leafy green vegetables high in vitamin K as a part of my meal.
James A. Duke, author of several books on herbal medicine, notes that garlic has nine different compounds that are antiaggregants (compounds that prevent the blood platelets from sticking together).
Alcohol
A study that appeared in the October, 2005 issue of the journal Alcoholism: Clinical & Experimental Research found that "Alcohol consumption is inversely associated with both platelet activation and aggregation." Another study, published in 1986 in the same journal, found signs of subclinical vitamin K deficiency in a study of 20 male alcoholics. Perhaps not coincidentally, the signs of fetal alcohol syndrome closely resemble the symptoms of vitamin K deficiency in newborns.
Based on my personal experience, I've noticed that red wine is an especially potent as a blood thinner. I had two glasses of red wine at a party a few years ago and started to have bleeding problems soon afterwards, including pain in one of my ovaries, which went away when I got home and ate some vitamin K rich foods.
Iron
There seems to be a yin-yang relationship between iron levels and blood coagulation. The following list includes a sampling of studies and articles that indicate when iron levels are high, platelet count is low and vice versa.
• When people have iron deficiency anemia, their platelet counts usually increase.
• Pubmed has a case study of a patient who overdosed on iron supplements. Following the overdose, "Vitamin K-dependent coagulation factors dropped within the next hours to very low levels. Thrombotest showed less than 3% of normal coagulation activity 8 h [sic] after oral intake."
• A study published in Renal and Urology News noted that "iron lowers platelet counts."
• The book, Hematology: Principles and Applications, notes that, "It is believed that iron plays some role in regulating thrombopoiesis because treatment of the iron deficiency with iron replacement has resulted in normalization of the platelets in patients with thrombocytopenic patients... ". (Thrombopoiesis means the process of blood clot formation.)
On a personal note, I developed iron deficiency anemia after going on a diet and eating a lot of vitamin K rich, coagulation inducing salads. My iron levels may well have been low before I went on the diet as anemia usually doesn't usually develop just overnight, but I think it was more than a coincidence that I only became symptomatic during my high vitamin K intake / salad phase. When I had my blood tested, during the times I was anemic my platelet count was out of range on the high side. My platelet count returned to normal levels again after I started taking iron pills and my iron deficiency anemia was corrected.
Exercise
Based on studies of female athletes, vigorous exercise seems to lower vitamin K levels. Women who are elite athletes, i.e. those who over exercise, instead of being healthy actually are at risk for hypoestrogenism, osteoporosis and vitamin K deficiency. Vitamin K is necessary to clot the blood, so by logical deduction then it may be prudent to consider the possibility that over exercising may thin the blood since it is known to lower levels of vitamin K.
At the other end of the spectrum, we know that people who remain stationary for long periods, such as people on bed rest, in car trips or travelers on long plane flights, are at risk for blood clots. One of my relatives developed a blood clot in his leg on a flight from Europe to the U.S. and had to have emergency surgery shortly after landing in the U.S.
By logical deduction then, the table below may illustrate the links between the conditions associated with remaining stationary and the conditions with over exercising, two conditions at the opposite end of the spectrum.
Remaining Stationary <=> Vigorous Exercising
Blood Clots <=> Vitamin K deficiency
Thinner blood
Higher estrogen levels <=> Low estrogen levels
Increased cancer risk <=> Decreased cancer risk
Table showing known links between exercise, estrogen levels, vitamin K, cancer and blood clotting.
Interestingly, a 2003 study from the University of Colorado Health Sciences Center found that blood clots in obese people could be dissolved with regular exercise.
Vitamin D is known as the sunshine vitamin because our bodies can produce it from the action of sunlight on the skin.
Sunshine / Vitamin D?
In Ayurvedic medicine, sunshine is supposed to be good for a person's circulation, which I've found usually means it also thins the blood. As noted above, other Ayurvedic remedies for improving circulation, such as cinnamon and ginger, have actually been proven in modern medical studies to be natural blood thinners. As such, it would be logical to consider the possibility that if Ayurvedic medicine scholars were correct about the spices thinning the blood, they may have been right about sunshine, too.
Interestingly, a recent medical study found that a "clinical trial of a biologically active metabolite of Vitamin D3 demonstrated an unanticipated reduction of thrombosis in cancer patients." Vitamin D is a fat soluble vitamin that we can obtain in two ways: 1) through food; or 2) it can be synthesized by the body after exposure to sunshine.
I don't know if this means that sunshine would have the same impact on blood as the vitamin D from the study, but it is interesting food for thought. If sunshine is found to be a blood thinner, it would confirm what Ayurvedic practitioners have thought to be true for thousands of years.
Cancer and Blood Clots
In Traditional Chinese Medicine (TCM) cancer is often viewed as a symptom of a circulation problem. In modern, Western medicine, the common assumption is that cancer causes blood clots. But what if the TCM version is really the most accurate view, and the reality was that blood clots, or a lack of circulation from blood clots, caused cancer? Perhaps not coincidentally, many factors that studies show may decrease the risk of cancer also thin the blood. These include sunshine, exercise, aspirin, heparin (a prescription anticoagulant), antibiotics, olive oil, fish oil, turmeric, vitamin E and garlic. For more on this topic, see my article on breast cancer, blood clots and excess vitamin K levels.
Avoiding Foods that Clot the Blood
Foods that clot the blood include those high in vitamin K, especially leafy green vegetables, saturated fats, and cultured foods with live bacteria that synthesize vitamin K in the intestinal tract. For more on this topic see my section: Foods and Environmental Factors That Cause the Blood to Clot
Summary
It is well known that foods that elevate vitamin K levels, such as lettuce and dandelion greens, may clot the blood. People who are taking anticoagulants are often warned to limit these types of foods so they don't counteract the effectiveness of their medicine.
However, it is often overlooked that many foods and environmental factors, especially those that lower vitamin K levels, may thin the blood. This information may be important for people on anticoagulants to be aware of in order to prevent their blood from becoming too thin.
Some people, like me, have genetic disorders that make us easy bleeders. However I have found that by controlling my diet by monitoring how much of the foods listed above I consume, I can usually keep my bleeding problems well under control.
