Hi. Thanks for your query. Noted the history and understood your concerns. Since you have been given the symptomatic treatment and antibiotic too but without any results for diarrhoea I would suggest you the following: Get the stool sample checked again for three consecutive days. Get the blood sample checked for diabetes, thyroid and liver functions. CT scan of the abdomen to see if there is any focus of infection. Colonoscopy helps sometimes to pin-point the cause. Once diagnosed to get any specific reason and you will be fine. If all the tests are normal then this may be IBS that is irritable bowel syndrome and get treated accordingly, control of stress and anxiety being one of the most important factors. Watch for the foods and beverages that instigate or enhance the problems and stop these altogether.
