I have been on warfarin for about 4 months. I have had a relatively stable INR level (1.9 to 2.7) for most of that time. Lately it has been dropping - 1.5 last reading. I have been working out more, and I've consumed more alcohol than during the first 3 months. I've also been eating healthier - more veggies, less junk food etc. I've also lost about 10 pounds.

Depending on what veggies you are eating that could lower your INR. Any deep green vegies are high in Vitamin K and that lowers INR's. You need to keep eating healthly of course so just inform your doctor as to what you are eating, drinking and exercising and the will be able to adjust your dose accordingly. Weight loss/gain can also affect your INR. I too am on Coumadin and will be fo the rest of my life due to a blood clotting disorder so feel free to ask as many questions as you want and I will try to help. The best one to help is always your doctor but I will try to help with my experiences if I can. Hope this has helped some, marjorie zych
