Irritable Bowel Syndrome (IBS) is a chronic functional gut disorder that affects the large intestine. Unlike inflammatory bowel diseases, IBS doesn’t cause structural damage but significantly impacts digestive function.
✔ Abdominal pain/cramping (often relieved by bowel movements)
✔ Altered bowel habits:
IBS-D (Diarrhea-predominant)
IBS-C (Constipation-predominant)

✓ Basic blood/stool tests (when needed)
• Low FODMAP Diet (temporarily eliminating fermentable carbs)
• Soluble fiber supplementation (psyllium)
• Identifying and avoiding trigger foods
• Smaller, frequent meals
Antispasmodics (for cramping)
Laxatives (IBS-C)
Anti-diarrheals (IBS-D)
Gut-directed antibiotics (rifaximin)
Probiotics
✓ Regular exercise
✓ Mindfulness/meditation
✓ Cognitive Behavioral Therapy (CBT)
✓ Improved sleep hygiene

“While IBS can’t be cured, most patients achieve significant symptom relief through personalized diet, stress management, and targeted medications.”
