Dear Dr. My mother has been on coumadin for several years due to two attacks of DVT in her legs. Now (yesterday morning) she was admitted to the hospital for internal bleeding during an outbreak of diarrhea. For the diarrhea her physician put her (Mon) on a liq-only diet of Pedialyte for 24 hours followed by a BRAT diet for 24 hors. The morning after the BRAT diet finished (yesterday) she lost a lot of blood in her stool and was sent to the ER for treatment. They did an INR and found it was 7.9. Her normal range is 2 to 3 on the coumadin dose she is taking (3 mg/d, 6d/wk). I am very concerned that the bleeding was CASUED BY the diets of the last two days. She ate no vegetables after Mon afternoon and took no supplements except Vit D3 (1000 u/day) and CaCO3 (liq. 1000 mg). Is it possible that she is suffering from coumadin poisoning?
