Gastroparesis - Topic Overview
What is gastroparesis?
After a meal, the stomach normally empties in 1½ to 2 hours. When you have gastroparesis, your stomach takes a lot longer to empty. The delay results in bothersome and possibly serious symptoms because digestion is altered.
Bezoar is a fairly rare condition related to gastroparesis. In this condition, food stays in the stomach for a long time and forms a hard lump. This causes food to get stuck in the stomach.
What causes gastroparesis?
Gastroparesis occurs when the nerves to the stomach are damaged or don't work. Diabetes is the most common cause. Other causes include some disorders of the nervous system, such as Parkinson's disease and stroke, and some medicines, such as tricyclic antidepressants, calcium channel blockers, and opiate pain relievers. This condition can also be a complication of gastric surgery.
What are the symptoms?
The most common symptoms of gastroparesis are:
- A feeling of fullness after only a few bites of food.
- Food coming back up your throat, without nausea or vomiting.
A person who has gastroparesis also may have episodes of high and low blood sugar levels. Gastroparesis may be suspected in a person with diabetes who has upper digestive tract symptoms or has blood sugar levels that are hard to control. Controlling blood sugar levels may reduce symptoms of gastroparesis.
How is gastroparesis diagnosed?
Your doctor will ask you questions about your symptoms and will do a physical exam. He or she may also need to do tests to check your stomach and digestion and to rule out other problems that may be causing your symptoms. Tests that may be done include:
- Gastric emptying scan. This test can show how quickly food leaves your stomach. A radioactive substance is included in a solid meal that you eat. It does not include enough radiation to harm you. This substance shows up on a special image, allowing a doctor to see food in your stomach and watch how quickly it leaves your stomach.
- Gastric or duodenal manometry. Manometry is a test that measures the strength and pattern of muscle contractions. This test may be done in the stomach (gastric manometry) or in the first part of the intestines (duodenal manometry).
- Upper gastrointestinal series.
- Upper gastrointestinal endoscopy .
- Abdominal ultrasound.
- Blood tests.
