Hi thanks for contacting HCM... Noted you have left lower side abdominal pain... It could be according to history...... -colitis (bacterial ) -non specific colitis -diverticulitis Here initially you can take antibiotic like ornidazole plus oflixacin... More fruits. Soft and bland diet taken.... As you have diarrhea maintain hydration. Probiotic can be taken.... Non veg food avoided... Avoid stress. If no improvement USG or colonoscopy needed. Stool examination might needed as if occult blood positive parasitic like amebiasis or inflammatory bowel disease suspected. Sweet potato good food for digestive benefit. Cooked oatmeal also good one. Take care. Dr.Parth
