Well, what I meant by the blood smell was that in the quantities associated with gas is all. The gas/methane was around the blood, but contains no real amount of it, and then the stool that has it in it is something else. Personally, all IBD stool to me has had a distinct odor. I guess I just meant the gas and blood mixing, maybe the walls of the intestine blocking the process that combines odor to it. The stool is different in my experience, doesn't smell like normal "healthy" stool. Gas tends to be basically odorless, and I am guessing it's possible because of the gas being around blood as much as it is around stool and normal bowel wall. Maybe the blood odor isn't strong enough. Stool, per volume, probably carries a stronger stench than blood, per volume...
