Hi. Thanks for your query. Noted the history of habit of holding poop, ate lots of chips but hold the poop and then had to pass motion and since then have been passing of soundless gas after taking any food, getting weak day by day. This is quite a rarely heard problem and the possible reasons can be as follows: Developed sort of IBS that is irritable bowel syndrome as there is no other condition befitting your symptoms. I would advise you the following: Take a mild laxative in the night at bed time and see the results. Avoid all the food a and beverages that instigate or enhance such a problem. Send the stool and blood for lab tests. Ultrasonography to see whether there is any detectable problem that can cause your symptoms. If all the tests are normal get treated as IBS. Control the anxiety and stress. Change the eating habits. Stop holding the poop. See the results and if no relief consult a Gastroenterologist.
