My husband has a colectomy due to a cancerous tumor in the colon. His surgery was open stomach. He had this surgery last year and all of his tests are clear. He continues to have trouble with his taste. It is not the metallic taste he had with the cancer, but it causes much anxiety for him and for me, not knowing what foods to prepare. He takes Ensure about three times a day, but it often gives him diarreah. He lost 30 lbs and has not been able to gain it back. He is 80 years old and usually very active despite arthritis. Please help if you can. Thanks
