The use of blood thinners like warfarin or aspirin after a heart attack to reduce the risk of another one is well established and proven. But what about other blood thinners that are being heavily promoted for weight loss? Are they effective, safe, and worth your money? This blog post will answer these questions and provide you with the facts you need to know about using blood thinners to lose weight. Let’s get started!

Do blood thinners make you lose weight?

Not exactly, but they do help you shed some pounds. By lowering blood pressure, blood thinners can help you lose weight more easily. Additionally, these medications may also decrease your appetite and cravings, which can also lead to weight loss.

How Do Blood Thinning Medications Work?

1. Lowering blood pressure

Blood thinners work by lowering your blood pressure. When you have high blood pressure, your heart needs to pump more blood around your body and it can put a lot of strain on the arteries that lead from the heart to the rest of the body.

2. Decreasing appetite and cravings

A number of studies have shown that people who take blood thinners tend to eat less and lose weight. This is because these medications can lower your appetite and make it more difficult for you to get full quickly without eating a lot. They may also decrease cravings in some people too, which also makes it easier for them to lose weight.

3. Lowers LDL cholesterol levels

Blood thinners can lower levels of bad cholesterol in your body, specifically low-density lipoprotein (LDL) cholesterol, which is known as “bad” cholesterol because it’s associated with an increased risk of heart disease. Studies have shown that taking low-dose aspirin or other blood-thinning medications like clopidogrel or warfarin over long periods of time can lead to significant reductions in LDL levels without any negative side effects. In fact, some studies show that taking aspirin along with other medications like statins can actually increase HDL levels, which is good cholesterol and is associated with reduced risk of heart disease as well as better overall health. So while they may not help you lose weight directly, they do provide other benefits such as the reduced risk of heart disease, which can help you lose weight over time.

What Are The Different Types Of Blood Thinners?

1. Warfarin (Coumadin)

Warfarin is one of the most commonly used blood thinners. It is approved by the FDA for the treatment of deep vein thrombosis (DVT) and embolism due to cancer. However, it has also been used to treat other conditions like atrial fibrillation and deep vein thrombosis, but it has not been found to be effective in preventing heart attacks or strokes.

Warfarin works by inhibiting the activity of vitamin K protein, which plays a role in clotting blood. When vitamin K is blocked by warfarin, it prevents clotting. When warfarin is in your body, it also inhibits your body’s production of vitamin K2 (menaquinone), which then leads to a decrease in overall clotting ability.

2. Aspirin

Aspirin is a common over-the-counter pain reliever that works by blocking the effects of prostaglandins on blood platelets and thrombi formation. Prostaglandins are hormones that play an important role in blood clotting and inflammation processes within the body. Aspirin works by blocking these prostaglandins from forming into thrombi that cause bleeding, thus helping you prevent unwanted hemorrhaging after a heart attack or stroke.

3. Coumadin

Coumadin is a combination of warfarin and an anticoagulant (blood thinner). It works by interfering with the formation of blood clots that occur during the healing of a heart attack or stroke. The clot-forming factors in your body are called prothrombin activators (F2, VIIa, IXa) and are activated by vitamin K. Coumadin works by blocking these clotting factors from being activated.

4. Plavix

Plavix is a drug used to prevent strokes and heart attacks in patients who have already suffered from one or more cardiovascular events. It works by reducing thrombus formation, which occurs when blood clots form within arteries following a heart attack or stroke. Thrombus formation can cause damage to the arteries, leading to further complications such as heart attack and stroke.

5. Heparin

Heparin is an injectable medication derived from animal blood modified with an anti-coagulant called dicumarol, which interferes with the normal functions of anticoagulants like heparin. Heparin is used to prevent thrombi and other blood clots in patients who suffer from acute coronary syndrome (ACS), unstable angina pectoris, peripheral vascular disease, deep vein thrombosis (DVT), and pulmonary embolism (PE), hemorrhagic stroke, intracranial hemorrhage, atrial fibrillation, and thrombophlebitis.

6. Heparin-like drugs

Heparin-like drugs are used to prevent clotting in patients who have suffered from a heart attack or stroke. These drugs bind to the F2, VIIa, or IXa clotting factors within the body and block their actions on platelets, thereby preventing the formation of clots that can cause heart attacks and strokes.

7. Warfarin (Coumadin)

Warfarin is a blood thinner that is commonly prescribed by doctors to prevent blood clots after a heart attack or stroke. It works by interfering with the normal formation of blood clots by blocking vitamin K epoxide reductase, which converts vitamin K into its active form (menaquinone). Without its active form, warfarin prevents the formation of prothrombin activators (F2, VIIa, IXa), which would normally activate these clotting factors in your body. By interfering with this process, warfarin prevents thrombi from forming and stops your body from having any further problems with blood clotting after an acute event such as a heart attack or stroke.

The Dangers Of Using Blood Thinning Medication For Weight Loss

1. Blood Thinning Medication Can Cause Heart Attack

Blood-thinning medication such as aspirin, clopidogrel, or warfarin can cause a heart attack in some people. This is because these medications can increase the risk of having a heart attack by blocking platelets from forming clots after a heart attack or stroke.

2. Blood Thinning Medication Increases the Risk of Stroke

Aspirin, clopidogrel, and warfarin are all blood-thinning medications that have been linked to an increased risk of stroke. In fact, it has been estimated that aspirin use increases the risk of stroke by 3 to 5 times in patients with atrial fibrillation. Furthermore, when combined with other factors such as age and high blood pressure, warfarin usage also increases the risk of stroke significantly.

3. Blood Thinning Medication Can Increase Your Risks for Heart Disease and Diabetes

Blood-thinning medication such as aspirin increases your chances of developing coronary artery disease (CAD), which is one of the leading causes of death in the United States today. Furthermore, blood thinners like aspirin and clopidogrel are known to increase your chances of developing Type 2 diabetes by 15% or more in some patients. This is because these drugs can indirectly damage your pancreas and impair insulin secretion from it leading to Type 2 diabetes symptoms such as excessive thirst, unexplained weight loss, and fatigue.

4. Blood Thinning Medication Can Cause Bleeding

Blood-thinning medication such as aspirin and clopidogrel can also cause bleeding in the stomach, lungs, brain, or even the skin. This is because these medications are known to interfere with blood clotting.

5. Blood Thinning Medication Can Lead to Liver Damage and Death

Blood-thinning medication such as aspirin or warfarin has been linked to liver damage and death in some patients. This is because these drugs are known to interfere with the production of vitamin K which is needed for your liver to produce proteins that are vital for its function. If you do not get enough vitamin K, your liver will fail to produce the proteins that it needs and will eventually die off because of this lack of nutrients.


Blood thinners are commonly misconstrued as effective weight loss aids. While they can cause weight loss while you’re taking the medication, this weight loss is only temporary. Blood thinners are not effective for long-term weight loss and pose serious health risks when used long-term. Blood thinners are generally safe and well-tolerated, making them a good choice for people looking to lose weight. They are, however, not suitable for long-term use and are not effective for long-term weight loss. If you’re considering taking blood thinners for weight loss, be sure to talk to your doctor first. They can help you decide which type is best for your situation and if they’re right for you.
