Bloating

Bloating is where your tummy feels full and uncomfortable. It's very common and there are things you can do to ease it. But see a GP if you feel bloated a lot or it does not go away.

You may be bloated if:

  • your tummy feels full or bigger than usual
  • you have tummy pain or discomfort
  • your tummy is rumbling or making noises
  • you're farting more than usual

The most common reason for bloating is having a lot of gas in your gut.

This can be caused by some food and drinks, such as some vegetables and fizzy drinks, or by swallowing air when you eat.

It can also be caused by a problem with your digestion, such as:

Some people feel bloated around the time of their period.

Sometimes, bloating that does not go away can be a sign of something more serious such as ovarian cancer.

Do

  • exercise regularly to improve your digestion and help prevent bloating – exercise can also help when you're feeling bloated

  • chew with your mouth closed to avoid swallowing air

  • drink plenty of water

  • eat foods high in fibre if constipated

  • eat smaller, more frequent meals instead of large meals

  • massage your stomach from right to left to release trapped wind

Don't

  • do not drink lots of fizzy drinks, alcohol or caffeine in coffee and tea

  • do not eat lots of foods that are known to cause gas, like cabbage, beans or lentils

  • do not eat large meals late at night before bed, or slouch when eating

  • do not eat lots of processed, sugary, spicy or fatty foods

  • do not eat food you are intolerant to, if you have a food intolerance

You can ask a pharmacist about:

  • laxatives to help treat constipation
  • medicines like Buscopan to help ease the bloating

What we mean by severe pain
Severe pain:
  • always there and so bad it's hard to think or talk
  • you cannot sleep
  • it's very hard to move, get out of bed, go to the bathroom, wash or dress
Moderate pain:
  • always there
  • makes it hard to concentrate or sleep
  • you can manage to get up, wash or dress
Mild pain:
  • comes and goes
  • is annoying but does not stop you doing daily activities

Treatment for bloating is often not needed. If you need treatment it will depend on the cause.

A GP may:

  • refer you to an NHS dietitian if general diet tips, such as cutting down on foods that trigger bloating, are not helping
  • refer you to a specialist for tests to find out what may be causing your bloating
