Coumadin & Diabetes Diet

Coumadin is a blood-thinning medication given primarily to patients who are at risk of stroke or heart disease due to blockages in the blood vessels or a propensity for clotting. Because deep vein thrombosis (blood clots in the legs) is a concern for diabetics with poor circulation in their extremities, Coumadin (also known as warfarin) may be prescribed to prevent complications from diabetes. The medicine in combination with your diabetes can leave you with some very strict dietary guidelines. Be sure to follow the diabetic diet and keep these factors about Coumadin in mind.

Does Coumadin Change My Blood Sugar Levels?

In extremely rare cases, Coumadin may have an adverse reaction leading to pancreatitis. When a patient develops pancreatitis (an inflammation of the pancreas), blood sugar levels may be impacted; however, these complications are extremely rare, and under normal circumstances Coumadin should not elevate your blood sugar. Some diabetic medications may have a slightly stronger effect because of the thinned blood, leading to lower blood sugar levels. Consult your medical professional if you become concerned about your low blood sugar levels.
In short, this means that you need to pay even more attention to your diabetic diet. Keep your blood sugar levels consistent to avoid poor interactions.

How Should I Change My Diet While Taking Coumadin?

Coumadin is a blood thinner, and patients should be sure to tell any health professionals that they are taking it before any surgeries, teeth cleaning or other procedures. Vitamin K is a natural coagulant, thickening the blood. Therefore, while maintaining your diabetic diet, it is important to be aware of the vitamin K content of your foods and get approximately the recommended daily allowance of vitamin K, but not more. Foods that are high in vitamin K are leafy green vegetables such as spinach, legumes including peanuts and peas, and some vegetable oils. Eating large amount of foods that are high in vitamin K can reduce the effectiveness of your Coumadin.

What Foods Should I Avoid While Taking Coumadin?

Some foods are known to have a thinning effect on the blood and can be multiplicative with the effects of Coumadin, resulting in blood that is too thin. Foods to avoid include cranberry juice, alcohol and excessive amounts of cinnamon. Green tea is also high in vitamin K and should be consumed in smaller quantities or avoided while taking Coumadin.
