Hi Dear, Welcome to HCM. Understanding your concern. As per your query you are having symptoms of loose stools and constipation after having food which could be due to many reasons such as -irritable bowel syndrome -poor absorption and inadequate digestion of food. -electrolyte imbalance in body -eating a lot of dairy products Need not to worry. You should start with drinking a lot of water , do light exercises and avoid fatty and heavy meals. Avoid intake of outside food. I would suggest you to consult gastroenterologist for proper examination. Doctor may order colonoscopy or other tests to look for blockages in your colon , barium studies and blood test for hormonal changes. Doctor may prescribe fiber supplement psyllium, calcium polycarbophil , osmotic laxatives , stool softeners and medicine to reduce acidity. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
