No. I mean, hopefully no. I think it's an ulcer, actually. My dad's started at about my age. I have shitty bought it myself health insurance (oh, $160 to them...that's a purchase) until my benefits kick in. I've noticed what triggers it: eating way too much or not eating enough. And Pepto kills it in about half a day. But I joke to myself it's cancer.
It's not like that thing on my belly I was convinced was a melanoma.
Take a multi-strain probiotics for goodness sakes. At least 12-15 billion CFU. Charcoal is great but you need the probiotics for healthy gut.
