Has anyone heard of a gastric diverticulum? I have been having intense GI pain and have had all tests, Upper GI, to Gall bladder scan and they are all normal, except it was seen that I have a gastric diverticulum. Only one, located on top of my stomach. They said imagine a fist and stick your thumb out. The fist is the stomach and the thumb is the diverticulum. They said when I eat foods that are hard to digest, they stay in my longer and when I eat again stuff gets pushed into the diverticulum and that causes the pain. I am told I can have surgery laproscopically to remove the diverticulum and it will be a 5 day stay in the hospital and a month recovery. I am just wondering if anyone else has gone through this!
