Hi Thank you for asking HCM I have gone through your query.Your problem is most likely irritable bowel syndrome.Stool Routine tests,tests for lactose intolerance and celiac disease should be done.If any malabsorption syndrome is there it should be treated with antibiotics like metronidazole.You should avoid stress as it can worsen the symptoms.If continuos diarrhea is there or with blood then a colonoscopy or sigmoidoscopy should be carried out to rule out other problems.Medications like alosetron and Lubiprostone are used in some patients with effectve results.Diet is also important.Avoid offending agents.Use probiotics and take enough fluids.Hope this may help you. Let me know if you have any further query.
