Irritable Bowel Syndrome (IBS) Treatments

Irritable bowel syndrome (IBS) is a common, long-term condition that affects the digestive system. It causes symptoms such as stomach cramps, bloating, diarrhoea and constipation, which can come and go over time and sometimes worsen after eating or during periods of stress. IBS does not damage the bowel or increase the risk of other bowel conditions, but it can have a significant impact on day-to-day life. There is no single test for IBS, so it is usually diagnosed based on your symptoms and pattern of bowel habits.

The most common symptoms of IBS include stomach cramps or pain that often eases after going to the toilet, bloating, and a change in bowel habits such as diarrhoea, constipation, or both at different times. Other symptoms can include excess wind, passing mucus, and a feeling that you have not fully emptied your bowels. Symptoms tend to come and go in flare-ups rather than being constant, and can be triggered by certain foods, stress or hormonal changes. Speak to a GP if you notice blood in your stool, unexplained weight loss or symptoms starting after the age of 50, as these are not typical of IBS and need investigating.

The exact cause of IBS is not fully understood, but it is thought to be linked to how the gut and brain communicate, sometimes causing the gut to become oversensitive or food to pass through it too quickly or too slowly. IBS can develop after a bout of gastroenteritis (known as post-infectious IBS), and it is also more common in people with a family history of the condition. Common triggers for flare-ups include certain foods and drinks, stress or anxiety, hormonal changes, and some medicines.

Antispasmodic treatments such as Buscopan IBS Relief work by relaxing the muscles in the bowel wall, easing the cramps and spasms that cause IBS pain, typically within 15 minutes of taking a dose. Bloating is often linked to gas building up in the digestive tract, and can be helped by eating smaller, more regular meals, cutting back on fizzy drinks and foods known to cause wind, and gentle exercise such as walking. Keeping a food and symptom diary can also help identify which specific triggers affect you.

There is no single test that confirms IBS. Instead, a GP will usually diagnose it based on your symptoms, how long they have lasted and their pattern, alongside blood tests to rule out other causes such as coeliac disease or inflammation. In some cases, further investigations like a stool test or colonoscopy may be recommended, particularly if you have symptoms that are not typical of IBS, to rule out other digestive conditions before confirming a diagnosis.

Trigger foods vary from person to person, but common culprits include fatty or fried foods, caffeine, alcohol, fizzy drinks, and foods high in FODMAPs, such as onions, garlic, beans and some fruits. Many people find it helpful to eat smaller, more regular meals, drink plenty of water, and gradually reduce these foods to see whether symptoms improve, rather than cutting them all out at once. A pharmacist or dietitian can help you put together a suitable eating plan, particularly if you are considering a structured low FODMAP diet.

IBS is usually managed with a combination of dietary and lifestyle changes and, where needed, over-the-counter treatments. Identifying and reducing trigger foods, managing stress and staying physically active can all help reduce how often flare-ups happen. For symptom relief, antispasmodic medicines like Buscopan IBS Relief can ease cramping and spasms as they occur. If symptoms are severe or do not improve with these measures, a GP may suggest other options, including talking therapies such as cognitive behavioural therapy (CBT), which have been shown to help some people manage long-term IBS.

Buscopan IBS Relief contains hyoscine butylbromide, an antispasmodic that targets the muscle contractions in the bowel responsible for IBS cramps and spasms, and is available over the counter for adults and children aged 12 and over. It should be taken as needed when symptoms start, rather than as a regular daily dose, and should not be used for more than two weeks without speaking to a doctor. Depending on your main symptoms, a pharmacist may also recommend other treatments, such as laxatives for constipation-predominant IBS or anti-diarrhoeal medicines for diarrhoea-predominant IBS.

There is currently no cure for IBS, as it is a long-term condition. However, most people are able to manage their symptoms effectively through a combination of diet, lifestyle changes and, when needed, medication, and many find their symptoms improve significantly or become much easier to control over time. Working out your personal triggers is often the most effective way to reduce how often flare-ups occur.

Despite the similar names, IBS (irritable bowel syndrome) and IBD (inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis) are different conditions. IBS is a functional disorder, meaning it affects how the bowel works without causing visible damage or inflammation. IBD is an autoimmune condition that causes ongoing inflammation and damage to the lining of the digestive tract, and can lead to symptoms such as blood in the stool, unexplained weight loss and fatigue, which are not typical of IBS. Because some symptoms overlap, a GP will usually carry out further tests to rule out IBD before diagnosing IBS.
