What is gastroparesis?

Gastroparesis is a condition in which food stays in the stomach for longer than normal.

Usually, the muscles around the stomach contract and grind food into small pieces, then mix those small pieces with acids and enzymes so the food can start to be digested. Then the muscles contract and push food out of the stomach into the duodenum.

If you have gastroparesis, the muscles around the stomach don’t work properly. Food isn’t broken down in the stomach as much as normal, and it stays there for longer.

What causes gastroparesis?

The causes of gastroparesis are not all that clear. It seems that in some people, the nerve to the muscles around the stomach, called the vagus nerve, isn’t working properly. For some people, the muscles themselves don’t work as well as they should.

You are more at risk of developing gastroparesis if you have diabetes. It is one of the complications of nerve damage caused by poorly controlled blood glucose levels.

Other causes include:

In some cases, there is no obvious reason for gastroparesis.

What are the symptoms of gastroparesis?

If you have gastroparesis, you probably feel that you just don’t digest your food properly, making you feel bloated and nauseous after a meal. Some people also:

If you think you might have gastroparesis, see your doctor.

How is gastroparesis diagnosed?

To diagnose gastroparesis, your doctor will talk to you, examine you and arrange some blood tests.

You may also be referred for other investigations, such as a ‘gastric emptying study’, an ultrasound, or endoscopy.

How is gastroparesis managed?

Although gastroparesis cannot be cured, the symptoms can be relieved. You can ease symptoms by:

  • eating fewer, smaller meals
  • eating easy-to-digest foods
  • taking medicines to improve the muscles around the stomach contraction and control nausea

If things don’t improve with changes to diet the and medicine, you can have a pacemaker inserted in the stomach to stimulate the muscles in the stomach. This is called gastric electrical stimulation. Talk to your doctor.

If you have diabetes, irregular emptying of the stomach can make it difficult to control blood glucose levels. It is important to get advice from your doctor.

Very severe cases may be treated by injecting botox into the valve between the stomach and small intestine, inserting a feeding tube, or surgery.
