Gastroparesis is where food passes through the stomach slower than it should. It's a long-term condition that can be managed with diet changes, medicines and other treatments.
Check if you have gastroparesis
Symptoms of gastroparesis start after eating and may include:
- feeling full sooner than usual – you may be unable to finish meals
- feeling sick and being sick
- tummy pain
If you've had these symptoms for a while, you may also be losing weight.
Non-urgent advice: See a GP if:
- you often feel full quickly when eating
- you often feel sick or vomit after eating
- you have tummy pain that will not go away or keeps coming back
- you have heartburn most days for 3 weeks or more
- you've been feeling bloated for 3 weeks or more
- you feel bloated regularly (more than 12 times a month)
- you have a swelling or lump in your tummy
These may be symptoms of gastroparesis or another condition with similar symptoms, so it's important to get it checked.
Immediate action required: Call 999 or go to A&E if:
- you have sudden and severe tummy pain
- your sick has blood in it
- your sick is dark brown or black and looks like coffee grounds or soil
- your sick looks and smells like poo
Tests for gastroparesis
If these tests do not show other causes for your symptoms, you may need:
- a gastroscopy (where a thin, flexible tube with a camera inside is passed through your mouth and into your stomach)
- tests to find our how long it takes for food to pass through your stomach
Treatment for gastroparesis
If you have gastroparesis, you may be recommended to make changes to your diet such as:
- eating 4 to 6 small meals a day, rather than 3 large meals
- reducing the amount of insoluble fibre you eat – this is a type of fibre that cannot be digested (for example, wholegrain bread, beans, and some vegetables and fruits)
- having a liquid diet (for example, foods like soups or meals blended in a food processor)
You may be referred to a healthy eating specialist (a dietitian) to help you make sure you're getting enough nutrients.
You may be given medicines for gastroparesis that can:
- help food move through your stomach faster, such as metoclopramide or domperidone
- stop you feeling sick and being sick
- help with pain
If your gastroparesis is linked to diabetes, you may also be offered ways to help you manage your blood sugar levels, such as using an insulin pump.
Depending on your symptoms, you may be offered other treatments including:
- a feeding tube if you have malnutrition (a feeding tube can help you get nutrients)
- botulinum toxin injections to help relax the valve between your stomach and small intestine
- gastro-electrical stimulation, where an electrical device is placed in the abdomen to help your stomach muscles work (this may not be available on the NHS)
- surgery where your stomach may be reshaped to help food pass through it more easily
Causes of gastroparesis
Gastroparesis is thought to be a problem with the nerves and muscles in the stomach. It's not always known what causes it.
It can be a complication of long-term conditions such as diabetes.
Gastroparesis can also be a complication after some types of surgery.
