Hi. Thanks for your query. Noted the history and understood your concerns. Abdominal cramps and loose stool 3-4 times in the morning with undigested food indicate the following: Intolerance to certain foods. Intestinal infection. IBS that is irritable bowel syndrome. I would advise you the following in such a situation: Send the stool for tests with detailed history so that the Pathologist can conduct multiple tests. Tests of blood for thyroid, diabetes and liver, kidney functions. Ultrasonography of the whole abdomen. Serum amylase and lipase for pancreatic functioning. CT scan of abdomen and colonoscopy as needed. Treatment will be obviously as per the cause thus found and clinical judgment of a Gastroenterologist. Identify the foods and beverages that instigate or enhance the problems and strictly to avoid all such things that you or your family have noted. Control of stress and anxiety is also a very important part of the management.
