Hi Dear, Welcome to HCM. Understanding your concern. As per your query your child have symptoms of severe diarrhea in children which seems to be due to disturbance of electrolytic balance . Well there can be many reasons for symptoms you mention in query like food intolerance , food allergy , bacterial or viral infection , parasitic infection or inflammatory bowel disease. I would suggest you to consult gastroenterologist for proper examination . Doctor may prescribe antibiotics like ornidazole , albendazole , omeprazole along with loperamide. Take oral rehydrating solution as well. You should take small and frequent meals rather than large meals at a time. You should eat light and non spicy , eat fresh fruits and vegetables and eat fruits like banana. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
