Irritable bowel syndrome (IBS) is extremely common in the UK. Around 17% of people experience IBS symptoms, although prevalence differs considerably between men and women: approximately 11% of men compared with 23% of women. This two-to-one gap may be one reason IBS in men is sometimes overlooked.

Although the underlying condition is the same, there can be differences in symptom patterns, the prevalence of specific IBS subtypes, and how often people seek support. Triggers are broadly similar, but their impact varies from person to person.

So, is IBS really different in men? Which symptoms are more common, and what can men do to manage the condition? Find out below.

Is IBS Different in Men?

It can be.

IBS itself is the same between men and women. The same diagnostic criteria are used to diagnose the condition, including the same symptoms. However, men can be more likely to experience particular symptoms compared to women or react to different triggers.

The differences are likely due to a combination of sex hormones, gut sensitivity, stress responses, and societal pressures.

What are the Symptoms of IBS in Men?

The most common IBS symptoms in men include:

• Abdominal pain or cramping

• Diarrhoea, constipation, or both

• Bloating and excess wind

• Sudden bowel urgency

• Incomplete bowel emptying

• Mucus in the stool

• Fatigue or nausea

Are Men More Likely to Have IBS-D?

IBS can present differently in men.

IBS-D (diarrhoea-predominant) is the most common subtype in men, according to a 2018 systematic review. Men are also less likely to experience chronic fatigue, chronic pelvic pain, and migraine headache compared to women.

Men can still experience IBS-C and are diagnosed with IBS-mixed at similar rates to women. These are just population-level trends.

What Triggers IBS in Men?

Men and women appear to have similar triggers. However, due to cultural or gender factors, men may come into contact with certain triggers more than others.

Common triggers include:

• Large or fatty meals

• Alcohol and caffeine

• Spicy foods

• High-FODMAP foods

• Irregular eating

• Poor sleep

• Stress and anxiety

• Gastrointestinal infections

Factors linked to work pressure, disrupted routines, and a reluctance to discuss stress can be higher in men. Often, a focus on tracking meals, bowel habits, sleep, and stressful events can have a greater impact than simply assuming food is always responsible.

Why IBS Can Be Missed in Men

IBS is more commonly diagnosed in women — likely due to a higher prevalence. However, the disparity can lead to the belief that it’s a “woman’s condition,” despite affecting around one in ten men.

Men may also be more likely to normalise diarrhoea, urgency, or abdominal discomfort, delaying a medical appointment due to embarrassment.

A 2022 study found that men had fewer contacts with the healthcare system compared to women. In part, that could be due to fewer sleeping problems, lower anxiety levels, and less chronic pain. But societal factors may still play a role.

How to Manage IBS in Men

IBS management in men is broadly the same as for women.

Focus on the following:

• Identify your bowel pattern. Management differs between diarrhoea-predominant and constipation-predominant IBS.

• Track your triggers. Keep a short diary covering food, alcohol, caffeine, sleep, exercise, and stress.

• Build a regular routine. Eat consistently, stay active, and avoid repeatedly skipping meals before eating a large portion.

• Make targeted changes. Reduce triggers you have genuinely identified instead of unnecessarily eliminating multiple food groups. Follow a low-FODMAP diet with professional support.

• Get the right advice. A GP, pharmacist or dietitian can recommend suitable approaches for diarrhoea, constipation, pain and bloating.

Men often get the most benefit from a solid routine and clear, actionable steps. That can lead to an overfocus on food or sleep, even when stress is the underlying trigger. Taking time to relax can make a big difference, whether that’s through mindfulness, exercise, or an enjoyable activity.

Finally Understand Your Unexplained Symptoms

Diarrhoea, constipation, bloating, and abdominal pain are challenging symptoms to manage, especially when persistent. IBS is one potential cause. However, these symptoms overlap with several other conditions.

The Functional Gut Clinic offers a range of testing options to help determine if your symptoms are due to a food intolerance, a motility disorder, IBS, or something else. For men, it can provide concrete answers, giving you the guidance to successfully manage your condition.

We share all your results with your doctor so that they can prescribe the best treatments. Testing can inform the diagnostic process, while a GP or consultant makes the diagnosis itself. Learn more about IBS symptoms and diagnostic testing.
