Hello, my wife had a total gastrectomy in August 2013. After the surgery she was taking hydromorphone - she was able to eat anything, her stool was normal. During her chemo/radiation in November she discontinued Hydromorphone and was experiencing diarrhea due to chemo/radiation. Since the beginning of January she suffers from abdominal pain, vomiting (mostly froth), feels gas bubbles traveling up her esophagus, loose diarrhea 1x daily. She takes Gas X and bentylol, but they bring only minimal relief. She keeps loosing weight.
