Gastroparesis is when the stomach cannot break down food and move it to the small intestine. With this problem, food either moves too slowly or not at all. This can cause food to harden and lead to blockages. Early treatment can improve outcomes.

This problem is more common in women.
The main risk factor for gastroparesis is diabetes, which can damage nerves. Other things that may raise the risk are:
- Gastroesophageal reflux disease (GERD)
- Surgery that involves the stomach or vagus nerve
- Taking certain medicines, such as anticholinergics or opioids
- Viral infection
- Diseases affecting the nerves, muscles, or hormones
- Diseases affecting metabolism (body’s ability to make and use energy)
- Anorexia or bulimia
- Radiation therapy or chemotherapy
- Alcohol use
You will be asked about your symptoms and health history. A physical exam will be done.
Your blood and urine may be tested to look for problems.
Images may be taken of the stomach and surrounding structures. This can be done with:
- Barium x-ray or CT scan
- Gastric emptying study— may also be done by MRI scan
Other procedures may be:
- Upper GI endoscopy —a thin, lighted tube inserted down the throat to examine the esophagus, stomach, and small intestine
- SmartPill—a pill-sized device that is swallowed to take images of the entire digestive system
Any underlying causes will need to be treated. The goal will be to ease symptoms. Options are:
Dietary changes may need to be made to ease symptoms. This may mean:
- Eating small meals several times throughout the day
- Following a liquid diet
- Limiting high-fat and high-fiber foods
People with severe symptoms may need to have nutrients delivered directly into the:
- Intestines—a tube is passed through nose, down the throat, and into the intestine. Long term use may require a tube passed through the stomach wall into the intestine.
- Bloodstream—through an IV
Medicine may be given to ease symptoms, such as nausea. Other medicines may be given to help the stomach empty. Examples are:
People with severe symptoms and those who are not helped by other methods may need surgery. This may include removing part of the stomach .
