Gastroparesis is a condition in which the spontaneous movement of the muscles (motility) in your stomach does not function normally.
Ordinarily, strong muscular contractions propel food through your digestive tract. But in gastroparesis, your stomach's motility works poorly or not at all. This prevents your stomach from emptying properly. Gastroparesis can interfere with normal digestion, cause nausea and vomiting, and cause problems with blood sugar levels and nutrition.
The cause of gastroparesis is usually unknown. When this is the case, it's called idiopathic gastroparesis (IG). When people who have diabetes develop gastroparesis, it's called diabetic gastroparesis (DG). Some people develop gastroparesis after surgery.
There is no cure for gastroparesis, but changes to your diet, along with medication, can offer some relief.
