My doc tells me that IBS is the reason for my putrid smelling gas and BMs. I don't have fecal body odor (at least that I'm aware of!) I've also got Ulcerative Proctitis, which to me would perhaps be more of a reason for the gross smells?
This has been ongoing for about 7-8 months now and it's to the point where I won't do my business in the house if we have company over...too embarrassing!
Any other of you IBS folks have this problem?
