Hi. Thanks for your query. Noted the history and understood the concerns. Fullness of stomach, difficulty in passing motion, indigestion and all the symptoms you have mentioned seem to be related to the stress or anxiety and other psychological problems that you have unless proved other wise by the following investigations: Get the stool tests done for three consecutive days. Tests of blood, should include complete thyroid profile not just TSH as TSH alone has no value and does not decide the dosages of Thyronorm or so. CT scan of abdomen. Colonoscopy and upper GI Endoscopy. If any disease is found in the course of clinical evaluation and investigations you will be treated accordingly. If all the investigations are normal then this is most probably IBS that is irritable bowel syndrome and you need a good control over the psychological problems. If required take an opinion of the Psychiatrist to help you better as you are habitual in masturbation for a long time too. Till then have symptomatic and supportive treatment with Pancreatic enzymes, laxatives for hard stools, multivitamins and mineral supplements and change the lifestyle to suit you the most.
