Gastroparesis is a disorder that affects the digestive system. During normal digestion, the stomach breaks down food and then contracts to push food down to the small intestine. With gastroparesis, there is delayed emptying of the stomach. Food either moves slowly through the digestive tract or does not move at all. This can pose problems since the food can harden causing blockage, nausea, and vomiting. Bacteria can also start to grow. Gastroparesis is a potentially serious condition. It requires care from your doctor.
The Stomach and Intestines

Movement of food in the digestive system is controlled by the vagus nerve. Gastroparesis occurs when this nerve is damaged and the muscles of the stomach do not work properly.
The main risk factor is
. Diabetes can damage the vagus nerve, which may lead to gastroparesis. High blood sugar can also damage blood vessels that carry nutrients and oxygen to the vagus nerve, preventing it from working properly. Other risk factors include:
Gastroesophageal reflux disease
Surgery that involves the stomach or vagus nerveTaking certain medicines (eg, anticholinergics or narcotics)Infection from a virusDiseases affecting the nerves, muscles, or hormonesDiseases affecting metabolism (body’s ability to make and use energy)Chronic diseaseAnorexia
If you have any of these symptoms, do not assume it is due to gastroparesis. These symptoms may be caused by other conditions. Tell your doctor if you have any of these: Feeling full early during a mealNo appetiteNausea and vomitingBloatingPain in your abdomen or esophagus (the muscular tube that carries food from your mouth to your stomach)HeartburnWeight loss
The following may worsen symptoms: High-fiber foods, like raw vegetables and fruitsFatty foodsCarbonated drinks
Your doctor will ask about your symptoms and medical history. A physical exam will also be done. The doctor may do: Blood tests
Tests to measure:
Stomach volume before and after a mealThe rate at which the stomach emptiesThe ability of the muscles in the stomach and small intestine to contract and relax
—to observe movement of food out of the stomach
or CT scan
—uses a milky fluid to coat the lining of the stomach intestines to look for blockage
Gastric emptying study—uses radioactive meal to measure stomach emptying directly with an x-rayGastric emptying study may also be done by MRI
—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 capture information on the digestive system
Talk with your doctor about the best treatment plan for you. Treatment options include:
Managing what you eat can help control gastroparesis. You may work with your doctor or a registered dietician to create a meal plan that is right for you. This may include: Eating small meals several times throughout the dayFollowing a liquid diet
and high-fiber foods
In severe cases, you may need to have nutrients delivered directly to your intestines (skipping the stomach) or directly to your bloodstream. Feeding tubes may be inserted down your throat or through your abdomen and into your intestines to help deliver food. Nutrients may also be given through a thin tube that is placed in one of your veins.
You may be given medicines that treat your symptoms and help your stomach empty. These medicines work by stimulating the stomach muscles to contract. Examples include: Metoclopramide (Reglan)Erythromycin
Other medicines may be prescribed to reduce nausea.
To help reduce your chances of getting gastroparesis, take the following steps: Control diabetes.
Since diabetes is a common risk factor for gastroparesis, it is important that you follow treatment plans from your doctor if you have diabetes.
Avoid medicines that delay gastric emptying.
Some medicines may keep your stomach from emptying properly. These include narcotic pain medicines, calcium channel blockers, and some antidepressants. Keep a list of all the medicines you are taking and share this list with your doctor. Make sure you talk to your doctor before stopping any medicines.
