Hi! My local doctor's feel that I have an insulinoma but the endocrinologist at the Cleveland Clinic in Florida thinks that I might be suffering from dumping syndrome. I had a Nissen fundoplication 5 years ago due to severe gerd but my hypoglycemia didn't start until 3 years later. I have had every scan you can think of and they can't find an insulinoma. I have been put on medication to keep food in my stomach longer but it hasn't helped. I had a gastric emptying study done and it was in the higher range of normal. I am so tired of feeling terrible all the time and I don't know what to do next.
