<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 34 year old son has pain in the upper part of his abdomen. He has suffered from it for a couple of years. His stomach swells up and he says it feels like it is putting pressure on his spine and his heart. Things like ZANTAC or mylanta help somewhat. No one seems to know what the problem is.  <response>: Hi. Thanks for your query. This is very classical history. The swelling in upper abdomen with pain. The simple tests are :::X-ray of the abdomen in a Standing position when the stomach has swollen-up. If necessary-Barium studies of the stomach in head-low position and upper GI Endoscopy examination. IF this is a volumes of the stomach-the treatment is simply putting a few stitches into stomach and fixing it to the abdominal wall. If the problem is due to obstruction at the duodenum, needs a major surgery to bypass this.
