What is the cause of intensely foul smelling flatus?

Spicy Foods: Take 4 tablets of dulcolax at night (all 4 as one dose). Next morning you will have good bm and this will clean your system. Then take Reglan (metoclopramide) 10 mg, one tablet at night for 2 weeks.

Foul flatus: People naturally have gas in their guts, and most pass it anally about 20 times/day. It can become more smelly due to sulfide chemicals produced by bacteria in the colon. Certain foods can increase the amount of gas made and passed: fermentable fiber, dietary starch, sugars like sorbitol and fructose, and complex carbs like beans. http://tinyurl.com/nxs6yl5.
