I've been passing constant gas for 5 months. I've tried digestive enzymes, probiotics, activated charcoal, chloryphll pills, pepto bismul, peppermint pills, olive leaf extract, beteine HCl. Got tested for celiacs, H Pylori, liver, thyroid, et cetera.
My symptoms are...
-constant foul smelling gas
-some oil in my stools
-the gas smells different depending on what i eat
-sometimes the gas smells LIKE the food i eat. if i eat pineapple, it smells like pineapple.
