Hi Dear, Understanding your concern. As per your query you have symptoms of upset stomach, diarrhea with loose stools and blood which seems to be due to intolerance to certain food items, eating too fast, overgrowth of bacteria in the small bowel, giardiasis or some medications. Need not to worry. I would suggest you to avoid food like dairy products, drink warm water and do light exercises and eat light and non spicy food. If condition doesn t get well then consult gastroenterologist for proper examination. Doctor may prescribe loperamide , laxative , omeprazole and antacids . For now give your child fruits like banana and lot of fluid. You should take oral rehydrating solution to maintain hydration status of body. Take diet rich in fruits and multivitamins. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
