Gastroparesis is a condition in which the muscles in your stomach don't function normally. Gastroparesis is a motility disorder.

The most common gastroparesis symptoms are:

• Nausea
• Vomiting
• A feeling of fullness after eating just a few bites (early satiety)

  In addition to nausea, vomiting and premature fullness, gastroparesis often causes:

  • Abdominal bloating
  • Heartburn or gastroesophageal reflux
  • Changes in blood sugar levels
  • Lack of appetite
  • Weight loss and malnutrition

    Why the stomach stops working
    Arguably the most important nerve in your body, the vagus nerve stretches from your brainstem to your colon. It helps orchestrate the complex microcircuits in your digestive tract, including signaling the smooth muscles in your stomach to contract in peristaltic waves — usually at the rate of about three contractions a minute. When these contractions slow or stop completely, food doesn't move out of your stomach into the duodenum as it should.

    Damage to the vagus nerve is the leading cause of gastroparesis, although the disorder can also result from damage to the stomach muscles themselves.

  • See your doctor if you have persistent digestive problems that don't improve with self-care measures.

  • Doctors use several tests to help diagnose gastroparesis. Some tests check specifically for signs of the disorder; others rule out conditions that cause similar symptoms.

  • The mainstay of gastroparesis treatment has long involved:

    • Dietary changes
    • Medications that increase stomach contractions

    • Because gastroparesis is most common in people with diabetes, controlling blood sugar levels is the best way to help prevent the disorder. ^{Reference: Mayo clinic}
