May also be called: Delayed Gastric Emptying; Stomach Paralysis

Gastroparesis (gas-tro-puh-REE-sis) is a digestive disorder in which the stomach's ability to empty its contents is delayed or absent even though there is nothing obstructing the digestive tract.

More to Know

Normally, the stomach moves about 90% of consumed food into the small intestine within 4 hours. In people with gastroparesis, food stays in the stomach longer, which can cause bloating, nausea, vomiting, a premature feeling of fullness, and unintentional weight loss.

Diabetes, certain medications, infections, and a number of diseases and conditions can cause gastroparesis. It also can be a side effect of upper gastrointestinal tract surgery that damages the vagus nerve, which controls the stomach.

Keep in Mind

Many people with gastroparesis find relief by making changes to their diet, such as eating low-fiber foods and having smaller, more frequent meals. Several medications and treatments are available that might help relieve symptoms.
