Stress and IBS: Can Stress Make IBS Symptoms Worse?

You may notice that your symptoms change when you are under more stress. Even when your diet stays the same, you may experience more abdominal pain, bloating, constipation, diarrhoea or urgency.

The connection between stress and IBS is complex. The gut and brain are closely connected, and stress can influence this two-way communication and the symptoms you experience.

What is the connection between stress and IBS?

IBS is recognised as a disorder of gut-brain interaction, which means that communication between the gut and brain plays an important role in the condition. Your gut and brain are constantly sending signals to each other. These signals help regulate digestion and bowel movements, as well as how sensations from the gut are experienced.

Stress can influence this communication in several ways. It can affect how quickly the bowel moves, which may contribute to diarrhoea and urgency or, in some people, slower bowel movements and constipation. Stress can also increase the sensitivity of the gut, which means that normal changes, such as the bowel stretching as food, gas or stool moves through it, may feel more uncomfortable or painful.

These changes can make your IBS symptoms more noticeable or harder to manage during periods of increased stress. This can happen even when other things, such as your diet, have stayed much the same.

Does stress cause IBS?

IBS is a complex condition that can develop through a combination of factors, and these may differ from person to person. There is no single cause.

Stress may be one factor involved, alongside changes in gut sensitivity and motility, previous gastrointestinal infections, changes in the gut microbiome and other factors that affect communication between the gut and brain. It is therefore more useful to think of stress as one part of a much bigger picture rather than the explanation for why IBS develops.

Can IBS itself make you feel more stressed?

The relationship between stress and IBS works in both directions. Living with unpredictable abdominal pain, bloating, constipation, diarrhoea or urgency can itself be stressful.

You may find yourself worrying about where the nearest toilet is, what might happen after eating, or how your symptoms could affect travelling, going to work or attending social events. Over time, worrying about symptoms can become another source of stress, which is why it can be useful to consider both your physical symptoms and the impact IBS is having on your everyday life.

What can help manage stress and the gut-brain connection?

There are many different ways to manage stress, and what helps will vary from person to person. The most useful approach is one that suits you, your lifestyle and the types of stress you are dealing with.

Simple strategies such as breathing exercises, mindfulness, relaxation, regular movement and making time for activities you enjoy can be useful ways of managing everyday stress. If you would like to try one of these approaches, choose something that feels manageable and fits naturally into your day.

You may need to try different strategies to find what works best for you. Sleep and regular movement are also part of the wider picture, which you can read more about in IBS and Your Daily Routine: Can Meal Timing, Sleep and Movement Affect Your Symptoms?

Cognitive behavioural therapy (CBT) is used for a range of health and psychological conditions, and specific approaches have also been developed and studied for IBS. IBS-focused CBT looks at the relationship between symptoms, thoughts, emotions and behaviours, and how these may influence each other.

For example, unpredictable symptoms can lead to worrying about when symptoms might occur, closely monitoring sensations in the gut or avoiding situations such as eating out, travelling or being away from a toilet. IBS-focused CBT can help identify these patterns and develop practical ways of managing symptom-related worry and reducing avoidance. This can help reduce the impact IBS has on everyday life and may also improve IBS symptoms for some people.

Gut-directed hypnotherapy is another treatment that has been studied specifically for IBS. It uses guided relaxation, imagery and suggestions that focus on the digestive system and communication between the gut and brain.

Research suggests that gut-directed hypnotherapy can improve overall IBS symptoms for some people. It is different from general hypnotherapy and may be delivered through a structured digital program or with a practitioner trained in gut-directed hypnotherapy.

When should you consider additional support?

If stress or worry about your IBS is starting to affect your everyday life, it may be helpful to talk to your GP or another healthcare professional. This may be particularly important if concerns about your symptoms are affecting what you eat, where you go or the activities you feel comfortable taking part in.

There are different types of support available depending on what you are experiencing and what you need. These can be used alongside dietary and medical approaches as part of managing IBS more broadly.

Finding what works for you

Stress is a normal part of life, and it is not always possible to change or remove the things that are causing it. Managing IBS is therefore not about trying to eliminate stress, but about recognising when it may be affecting your symptoms and finding ways to manage your response to it.

This might include everyday strategies that help you cope during stressful periods or, when appropriate, an IBS-specific approach such as CBT or gut-directed hypnotherapy. Finding what is useful for you may take some trial and error, and the approach may change depending on what is happening in your life.
