Gastroparesis is a stomach disorder in which food moves through the stomach more slowly than usual. People with gastroparesis suffer from chronic nausea and vomiting.

Although numerous things can contribute to gastroparesis, diabetes and previous surgeries are the most common causes. Diabetes can be a cause due to the prolonged levels of high glucose that slowly injures the nerves in the stomach. In some cases where a peptic ulcer may have obstructed the stomach, the muscles of the stomach slowly dilate, and even with surgery the muscle never regenerates again.

An estimated 3 percent to 5 percent of the US population suffers to sme degree from the symptoms of gastroparesis.
