I have had gall bladder surgery, and the gastric bypass but now the odor that comes from my body when I pass gas is unbearable. I can not let out a fart and it not be noticed even thou there was no sound. You can not go to the bathroom after I go for several hours this is so embarssasing. I need some help with just that. I also have bloating, gas pain in the stomach and constipation. Is there anything that will help me.
