Irritable bowel syndrome (IBS) can cause stomach pain, bloating, gas, loose motions, constipation, or discomfort after eating certain foods. Stress, anxiety, irregular meals, poor sleep, spicy foods, tea, coffee, milk products, or oily foods may trigger symptoms in many people. IBS often becomes frustrating because symptoms can continue for a long time, even after trying different treatments. Many people feel better by eating smaller meals, avoiding overeating, reducing spicy and processed foods, and limiting caffeine or alcohol. Some patients benefit from a low FODMAP-style diet under guidance from a dietitian. Regular sleep, stress control, walking, yoga, and relaxation exercises may also help reduce stomach sensitivity and improve bowel habits over time. Treatment usually depends on whether IBS causes more loose motions, constipation, pain, or bloating. Medicines may help some people, but they should only be used under proper medical supervision. Please consult a doctor again if you develop weight loss, blood in stool, fever, severe weakness, or worsening symptoms.
