Eating hot peppers does not cause ulcers. In fact, among the many health benefits of capsaicin, it lowers acid production in the stomach. It's actually been considered as a preventative treatment when taking things that DO actually cause ulcers--again, spicy food not being one of them.

This connection between spicy foods and ulcers is a long perpetuated myth that has been disproven over and over again. Capsaicin can, however, aggravate preexisting ulcers.

Yeah at a certain point it’s not about how much mouth pain you can stand. It’s definitely unhealthy for your gut to eat that insane level of spicy food that often. Even in Indian and Szechuan cooking they are not trying to destroy you.

I found myself having to eat a lot more probiotics and stuff when I was eating spicy food all the time. Once you pass the habanero threshold I think there is potential for damage… at least that’s my experience.
