If you develop symptoms of IBS, it is important to see a doctor for an evaluation. This is especially true if your symptoms are severe, ongoing, or if you notice any blood in your stools, unexplained weight loss, fever, or severe diarrhea. While IBS does not cause these symptoms, it's essential to rule out other more serious conditions. A healthcare professional can assess your symptoms and provide an accurate diagnosis.

Diagnosing IBS involves ruling out other conditions that could be causing similar symptoms. Your doctor may perform various tests, including blood tests, stool tests, and endoscopic investigations like sigmoidoscopy or colonoscopy. These tests help rule out infections, inflammatory bowel disease, coeliac disease, food allergies, and bowel cancer. If your tests come back normal and you have been experiencing IBS symptoms for at least six months, your doctor may diagnose you with IBS.

Adopting healthy lifestyle habits can help reduce IBS symptoms. Increasing dietary fiber intake can add bulk to your stools and make them softer and easier to pass. Gradually increase your fiber intake by consuming fruits, vegetables, and high-fiber cereals. It's important to drink plenty of water along with fiber to avoid bloating and discomfort. Identifying and reducing intake of trigger foods, such as gas-producing foods, lactose-containing products, alcoholic drinks, and artificial sweeteners, can also help manage symptoms. Consulting with a doctor or dietitian can provide personalised guidance. In some cases, a low FODMAP diet, which limits certain sugars that can trigger IBS symptoms, may be recommended.
