Irritable Bowel Syndrome (IBS) is a common functional gut-brain disorder that affects how your gut and brain interact, leading to hypersensitive intestines and abnormal muscle contractions. Its core symptoms include abdominal pain or cramping linked to bowel movements, along with altered habits like diarrhea (IBS-D), constipation (IBS-C), or both (IBS-M), accompanied by significant bloating and gas. Treatment is multi-faceted, focusing on dietary changes like the Low FODMAP diet (which eliminates then reintroduces fermentable carbs), stress management (through therapy or mindfulness), and medications to control specific symptoms like spasms or constipation. For a formal management plan, you should consult a Gastroenterologist. The cost can add up, including specialist visits, potential tests, and specific diets or supplements. The most effective practical guidance is to keep a detailed "symptom and food diary" for 2-3 weeks to clearly identify your personal trigger foods and stressors, which is the first step toward regaining control.
