How to Lose Weight While on Coumadin

Doctors often prescribe Coumadin, the brand name for the blood-thinning medication also known as warfarin 1. The medication also has a number of side effects and risks, such as bleeding complications. Vitamin K might affect your blood’s thickness, and because many typical “diet foods” such as spinach and other leafy green vegetables contain vitamin K, you might think you cannot lose weight. Instead of avoiding vegetables, talk with your doctor about the best diet plan for you, and your doctor will work with you so that you can reach your weight loss goals and improve your overall health.

Eat the same amount of vitamin K each day. This way, you can eat salads and other nutritious vegetables, and your doctor can adjust your Coumadin dosage. Vitamin K-rich foods include kale, chard, spinach and collard greens.
