I recently had an upper endoscopy on August 17th, 2012. On my discharge instructions, it was annotated that food was still present in the body of my stomach. I'm 48 years of age, 5' 5", and 165 pounds. I also have type 2 diabetes. My gastroenterologist wrote an order to obtain gastric emptying study to evaluate for gastroparesis. What is gastroparesis, how and why do you get it? Does it cause any serious complications with my stomach?
