Gastroparesis is a condition that reduces the ability of the stomach to empty its contents. It does not involve a blockage (obstruction).
The exact cause of gastroparesis is unknown. It may be caused by a disruption of nerve signals to the stomach. The condition is a common complication of diabetes. It can also follow some surgeries.
Risk factors for gastroparesis include:
People with diabetes should always control their blood sugar level. Better control of blood sugar level may improve symptoms of gastroparesis. Eating small and more frequent meals and soft foods may also help relieve some symptoms.
Medicines that may help include:
- Cholinergic drugs, which act on acetylcholine nerve receptors
- Metoclopramide, a medicine that helps empty the stomach
- Serotonin antagonist drugs, which act on serotonin receptors
Other treatments may include:
- Botulinum toxin (Botox) injected into the outlet of the stomach (pylorus)
- Surgical procedure that creates an opening between the stomach and small intestine to allow food to move through the digestive tract more easily (gastroenterostomy)
Many treatments seem to provide only temporary benefit.
