Over the past several months I've noticed that I've been having blood in my stool on occasions. It's quite evident when I wipe as well. I've been monitoring this over the past few months and I realized that it only happens after I've eaten spicy foods. I will see it either on the same day or the day after I have eaten the spicy foods. My stool is completely normal when I don't eat spicy foods. I've monitored this over the past months and that's what I've noticed. I can go several weeks with no spicy foods and my stool is fine, but as soon as I eat something spicy, either that day, or the next day, I'll have blood in my stool. Why?
