IBS flare ups

Overview

IBS (irritable bowel syndrome) is a chronic digestive condition that affects the large intestine. It causes belly pain, bloating, and changes in bowel habits like diarrhea and constipation. A 'flare-up' is a phase when these symptoms become more noticeable or severe, sometimes after a trigger.

Yes. IBS is one of the most common digestive complaints, affecting around 1 in 5 people at some point in their lives.

It can affect anyone, but it is more common in women and often begins in early adulthood (before age 50). It also affects many older people and can persist for years.

Symptoms

Common symptoms

• Belly cramping or pain that often improves after a bowel movement
• Bloating and a feeling of fullness or swelling in the belly
• Changes in stool frequency — going to the toilet more or less often than usual
• Changes in stool appearance — diarrhea, constipation, or alternating between the two
• Mucus in the stool
• A feeling of not being able to empty the bowel completely

Symptoms in children

• Children with IBS may complain of vague belly aches that are hard to describe
• They may have diarrhea or constipation, sometimes with mucus
• They may feel bloated or gassy
• Children might avoid eating because they fear the pain after meals

Symptoms in older adults

• Older adults may have similar symptoms but need careful checking, as other conditions can mimic IBS
• Constipation may be more common
• New symptoms in older age should always be discussed with a doctor promptly

Causes

Main causes

• Experts aren't sure exactly what causes IBS, but it seems to involve problems in how the brain and gut communicate.
• Food may move too quickly or too slowly through the intestines, leading to diarrhea or constipation.
• Nerve endings in the gut may be overly sensitive, so normal amounts of gas or stretching feel painful.
• Changes in the balance of bacteria in the gut may play a role.
• Flare-ups can be triggered by certain foods, stress, hormonal changes, or infections.

Risk factors

• Being female
• Being under age 50
• Having a family history of IBS
• Experiencing high levels of stress or anxiety
• Having had a severe digestive tract infection
• Having an overly sensitive 'gut-brain axis'

When to see a doctor

See a doctor urgently if:

• See a doctor urgently if you have blood in your stool, unexplained weight loss, a fever, or abdominal pain that wakes you from sleep.
• If you are over 50 and your bowel habits have changed, arrange an urgent appointment.

Book a routine appointment if:

• Make a routine appointment if you have ongoing belly pain or changes in bowel habits that last more than a few weeks.
• If your usual IBS symptoms become more frequent or severe, discuss it with your doctor.

Diagnosis

A doctor will ask about your symptoms, medical history, and check your abdomen. There's no single test for IBS. Doctors often diagnose it based on your symptoms and by ruling out other conditions.

Tests that may be done

• Blood tests to check for anemia, celiac disease, or other conditions
• Stool tests to rule out infections or inflammation
• Breath tests to check for lactose intolerance or bacterial overgrowth
• A colonoscopy (a camera test of your large intestine) if you have 'red flag' symptoms or are older

What to expect at your appointment

Your doctor may ask you to keep a diary of your symptoms, foods, and stress to look for patterns. You may be referred to a specialist in digestive health (a gastroenterologist) for further assessment.

Treatment

There's no cure for IBS, but flare-ups can be managed. Treatment focuses on relieving symptoms and helping you live comfortably. It often includes self-care, dietary changes, and sometimes medicines or mental health support.

Self-care at home

• Keep a symptom diary to spot your personal triggers
• Eat smaller, more regular meals and avoid heavy, fatty foods
• Drink plenty of water and reduce caffeine and alcohol
• Try relaxation techniques like deep breathing or yoga to manage stress
• Get regular, gentle exercise like walking or swimming
• Apply gentle warmth to your belly with a heat pad to ease cramps

Medical treatments

Your doctor may recommend medicines available over the counter or by prescription to help with specific symptoms like diarrhea, constipation, or pain. These are chosen based on your individual pattern. They may also suggest a special diet, probiotics, or talking therapies to help with the link between your brain and gut. Always discuss any treatment with your doctor or pharmacist before taking it.

Living with this condition

Living with IBS means staying aware of your triggers and building a toolkit that works for you. Flare-ups can be unpredictable, but you can often shorten them by sticking to a routine and reaching for the calming techniques that you know help.

Lifestyle tips

• Build a regular sleep schedule to help your gut rest
• Exercise most days, even if it's a short walk
• Practice stress-management skills like mindfulness or meditation
• Plan ahead for travel or meals out by bringing safe snacks

Diet and exercise

There's no one-size-fits-all diet for IBS. Many people feel better with a diet low in certain carbohydrates called FODMAPs, but this should only be done with the help of a dietitian to make sure you get enough nutrients. Eat a balanced diet and avoid skipping meals. Regular exercise helps the gut move and can reduce stress.

Mental health and emotional wellbeing

IBS flare-ups can cause anxiety, low mood, and embarrassment. It's normal to feel frustrated or worried. Remember that stress often makes IBS worse, so looking after your mental health is part of looking after your gut. Talking to a counselor or therapist can really help.

Prevention

There is no known way to prevent IBS itself, but you can often prevent flare-ups by managing triggers, eating well, staying active, and reducing stress.

Complications

If left untreated

• IBS doesn't cause permanent damage to your intestines, but untreated severe symptoms can lead to a lower quality of life.
• Avoiding many foods out of fear can lead to poor nutrition.
• Living with constant discomfort can lead to anxiety and depression.

Long-term outlook

With the right support, most people with IBS manage their flare-ups well and live full, active lives. Symptoms may come and go, but you can learn to control the impact they have on you.
