Quick answer

What is Gastroparesis?

Gastroparesis means the stomach empties its contents into the intestine much more slowly than normal, even though there is no physical blockage. This happens because the nerves or muscles controlling the stomach are not working properly.

  • How it is treated: Treatment aims to relieve symptoms and maintain nutrition.
  • Self-care: Eating smaller, more frequent meals that are lower in fat and tough fibre, chewing well, staying upright after eating, and keeping well hydrated all help.
  • When to seek help: See a doctor about persistent nausea, vomiting or early fullness.

What it is

Gastroparesis means the stomach empties its contents into the intestine much more slowly than normal, even though there is no physical blockage. This happens because the nerves or muscles controlling the stomach are not working properly. Symptoms include feeling full quickly, nausea, vomiting (sometimes of undigested food), bloating and upper-abdominal discomfort, and it can make blood sugar harder to control in people with diabetes. The commonest identifiable cause is long-standing diabetes, though many cases have no clear cause or follow surgery or certain medicines. Diagnosis involves ruling out a blockage and, often, a test measuring how quickly the stomach empties.

How it is treated

Treatment aims to relieve symptoms and maintain nutrition. Dietary changes are central — smaller, more frequent meals that are lower in fat and hard-to-digest fibre, and softer or liquid foods when symptoms are bad. Medicines that encourage the stomach to empty and control nausea can help. Where diabetes is the cause, improving blood sugar control is important. Severe cases may need specialist input and, occasionally, other treatments to maintain nutrition. Care is tailored and often shared with a dietitian.

Lifestyle and self-care

When to see a doctor

See a doctor about persistent nausea, vomiting or early fullness. Seek urgent care for persistent vomiting causing dehydration, or if you cannot keep fluids down.
