Hi everyone, can soneone help me, i have been haveing this putrid smell comeing from my mouth from my stomach for a long time. It is a farty type of smell and can funk out the entire room. It happens a couple of times a day it isnt constent. My stomach is very noisey all the time and i get a popping sensation then the smell comes out of my mouth. This is extremely uncomfortable and embarassing with people always asking "have you farted". I have tryed changing my diet dont drink or smoke but still the smell comes. I have had an endoscopy on my sineses and an endoscopy on my stomach all of which have come back negative. My doctor has just about given up and feel like am wasteing his time when i go see him now cause he hasnt got a clue whats up with me, can anyone please help!!
