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.
Symptoms of bloating
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
Causes of bloating
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:
constipation
a food intolerance
coeliac disease
irritable bowel syndrome (IBS)
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.
How to reduce bloating
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
A pharmacist can help with

laxatives to help treat constipation

weeks or more

Treatment for bloating
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
