Hi Dear, Understanding your concern. As per your query you have symptoms of severe diarrhea along with vomiting which seems to be due to disturbance of electrolytic balance and could be due to food intolerance, 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. Best Wishes, Dr. Harry Maheshwari
