What is IBS (irritable bowel syndrome)

• IBS (irritable bowel syndrome) is a common condition that affects the digestive system.

• It causes symptoms like stomach cramps, bloating, diarrhoea and constipation. These tend to come and go over time, and can last for days, weeks or months at a time.

• It's usually a lifelong problem. It can be very frustrating to live with and can have a big impact on your everyday life.

• Diet changes and medicines can often help control the symptoms.

• The exact cause is unknown – it's been linked to things like food passing through your gut too quickly or too slowly, gastroenteritis, oversensitivity in your gut, stress and a family history of IBS.

Main symptoms of IBS (irritable bowel syndrome)

The main symptoms of IBS (irritable bowel syndrome) are:

• stomach pain or cramps – usually worse after eating and better after doing a poo

• bloating – your tummy may feel uncomfortably full and swollen

• diarrhoea – you may have watery poo and sometimes need to poo suddenly

• constipation – you may strain when pooing and feel like you cannot empty your bowels fully

There may be days when your symptoms are better and days when they're worse (flare-ups). They may be triggered by food or drink.

What can trigger symptoms of IBS

IBS flare-ups can happen for no obvious reason. Sometimes they have a trigger like:

• alcohol

• caffeine

• certain foods, such as spicy or fatty food

• stress and anxiety

• regular antibiotic use

Other symptoms of IBS

IBS can also cause:

• farting (flatulence)

• pooing mucus

• tiredness and a lack of energy

• feeling sick (nausea)

• backache

• problems peeing, like needing to pee often, sudden urges to pee, and feeling like you cannot fully empty your bladder

• not always being able to control when you poo (bowel incontinence)

• pelvic pain

See a GP if:

• you think you might have IBS (irritable bowel syndrome) and have had symptoms for over 4 weeks

They can check for IBS and do some tests to rule out other problems.

Ask for an urgent GP appointment or get help from NHS 111 if:

• you have lost a lot of weight for no reason

• you're bleeding from your bottom or have bloody diarrhoea

• you find a hard lump or swelling in your tummy

• you have shortness of breath, noticeable heartbeats (palpitations) and skin that's paler than usual

These could be signs of something more serious.

You can call 111 or get help from 111 online.

Diet, lifestyle and medicines for IBS (irritable bowel syndrome)

Things you can do to help with IBS (irritable bowel syndrome)

There's no single diet or medicine that works for everyone with IBS (irritable bowel syndrome). But there are things that can help if you have been diagnosed with IBS, to help improve your symptoms or avoid making them worse.

Do

• try to eat a healthy, balanced diet

• keep a diary of what you eat and any symptoms you get – try to avoid things that trigger your IBS

• try to drink at least 8 to 10 drinks of fluid (around 1.5 litres) a day, such as water or non-caffeinated drinks such as herbal tea

• try to find ways to relax

• get plenty of exercise

• try probiotics for a month – they may help any symptoms caused by gut bacteria changes

Don’t

• do not delay or skip meals

• do not eat too quickly

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

• do not eat more than 3 portions of fresh fruit a day (a portion is 80g)

• do not drink more than 3 cups of tea, coffee or any other caffeinated drink a day

If you worry about getting IBS symptoms while you're away from home, you can buy a key from the Disability Rights UK shop to help you access public toilets.
