This is not quite an orthodox pepper question, but you are the most likely of any I know to be able to answer it. I understand the hot element in peppers is capsaicin, which is an organic substance which is metabolized in our stomach and intestinal tract. So why, after consuming peppers, when I have a bowel movement does my anus burn? I assume this happens to us all, not just me. Is it that the capsaicin is not completely changed in its journey?
A: Hello Ken:
That condition, known as "jaloproctitis," does not affect everyone. For example, I have never experienced it. I think you’re on the right track for figuring it out. My theory is that certain people don’t digest or metabolize all the capsaicin in the food and some of it reaches the sensitive membranes of the anus during bowel movements.
