Hi. Thanks for your query, albeit short and specific. Noted the history and understood your concerns. The reasons for smelly farts can be as follows: Intestinal infection with gas producing bacteria. Imbalance of intestinal bacterial flora. I would advise you the following in such a situation: Get the stool tests done and the routine blood tests. Ultrasonography of the abdomen to see for any gall stones, obstruction or colon inflammation. Clinical evaluation by your Doctor and a course of an antibiotic, metronidazole. Probiotics. Identify the foods an beverages other than you have stopped to see if these instigate or enhance your problems and stop these. Avoid stress and anxiety to avoid aerophagia. Good diet and exercises. Pancreatic enzymes with food can also be tried. This way you can get rid of the problems.
