Hello dear I understand your concern Your diarrhea could be a gastroenteritis (bacterial , protozoa infection) or IBS, Celiac disease, Microscopic colitis. I advice to to consult the Gastroenterologist for better evaluation and undergo following investigation: Stool microscopy and culture Blood tests: Full blood examination, LFT, ESR, and serological testing for coeliac disease Abdominal ultrasound, endoscopy to rule out the ulcer and colonoscopy. Hydrogen breath testing to rule out malabsorption. Doctor will give following advises: Take solubel fiber like ispagula husk. if not responds then laxative like sorbitol and lactulose will help Avoid spicy diet , take small frequent meal rather than large meal. Anti diarrheal: loperamide Tablet metronidazole Sporolac sachet in half glass of water. Drink ORS solution and boiled rice with added lemon and salt to mainatin the hydration. Take diet like banana, applesauce, yogurt, buttermilk and toast. Avoid stress and do regualr exercise like walking and yoga. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
