What is gastroparesis?
Gastroparesis, also known as delayed gastric emptying, is the slowing of food from the stomach to the small intestine. This happens when the vagus nerve is damaged by illness or injury.
What causes gastroparesis?
Most people diagnosed with gastroparesis have idiopathic gastroparesis, meaning a health care provider cannot identify the cause, even with medical tests. Damage to the vagus nerve can lead to gastroparesis, particularly as a product of prolonged high blood glucose levels. For this reason, diabetes is the most common known cause of gastroparesis.
Other causes may include intestinal surgery and diseases of the nervous system, like multiple sclerosis or Parkinson’s disease.
What are the symptoms of gastroparesis?
Gastroparesis can be difficult to diagnose because symptoms resemble those of other diseases. The symptoms of gastroparesis may vary in intensity over time in the same individual, and they may occur frequently in some people and less often in others.
Common symptoms include:
- Abdominal bloating
- Gastroesophageal reflux or acid reflux
- Lack of appetite
- Stomach pain
Symptoms may be aggravated by eating greasy or rich foods, large quantities of foods with fiber, or drinking beverages high in fat or carbonation.
