Hi , My Father has Diabeties, high blood pressure and Asthama. Recently he had a problem with hemoglobin levels in his blood. In the last 4 days his hemoglobin percentage got down from 7 to 4. He had blood vomitings and motions. Blood was supplied to him and after the hemoglobin has increased to 8 , they did endoscopy and they diagnosed as duodenal ulcer. After giving some antibiotics vomitings were controlled but now he had frequent urination problem. I Am just wondering is that a common symptom or anything to worry. As he has respiratory problem too, is surgery for ulcer is advisable? Please suggest! Thanks, Priya
