Hello, Welcome to Chat Doctor. From your query, I suspect he may have Gastric outlet obstruction or peptic ulcer. In gastric outlet obstruction, Food can not pass through intestine from stomach due to obstruction. This results in accumulation of food in stomach and lead to recurrent omitting and abdominal pain. Chronically it ends in loss of weight. There are many causes for gastric outlet obstruction. Some are Chronic peptic ulcer disease, gastric polyps and gastric cancer. It is essential to do an upper GI endoscopy to find the cause. Also do H. Pylori test. If it is a peptic ulcer disease with H. Pylori, antibiotics and proton pump inhibitors like pantoprazole are the treatment. If it is found to be a polyp or cancer, it either needs removal or chemo and radiotherapy. Depends upon the position and involvement and extent, treatment vary. Kindly consult a Gastroenterologist. Hope this helps. Take care. Chat Doctor.
