When I was an alcoholic I diagnosed myself with lactose intolerance. I’d have the Gatling Shits and wonder ‘Hmm was it the 14 tallboy cans of beer last night or the half liter of milk I had for lunch? Must have been the milk.’
So your lactose intolerant huh? That sucks. I used to wonder what food was causing my rectum to bleed so much, but I've diagnosed that it wasn't something to worry about until my 40s.
Bum bleeding is often resolved by reducing fibre. It happens because of too much traffic through your gut, fibre is nothing but extra traffic, it has no nutrient value
constipation can cause that, if shits are too hard too.
Dealing with bleeding in my 40s after putting it off for a few years, don't recommend.
Yeah it started for me around 18 or so. I've put it off for 18 years now. I'm sure it was a mixture of drinking, dehydration, excessive running, stress and poor diet. For a little while I couldn't figure out if it was hemmroids from stress/riding a motorcycle and other strains but when I read more into the damages that can be done from long distance running all the time, I think that and diet caused most of it. Excessive alcohol use following that up didn't help much. I've learned that bad choices are my Pokemon, I apparently just have to catch them all before I learn anything
Username checks out?
How......can you even long distance run without much real food, and I'll assume both were a regular thing?
I didnt get lactose intolerance until I was in my 30s. So weird that my body just decided "Nah, Im good with dairy products" all on it's own.
Really wish I would have discovered that earlier in life, before I developed my crippling cocoa pebbles addiction.
Guess you only got a little trial period of lactase persistence, as a treat, but it ran out too soon.
Didn't even get a reminder to renew my subscription, dirty bastards.
That's actually the normal way your body is supposed to be. Most mammals lose their tolerance a little after they are weaned. Only some portions of humans retained lactase in their guts, generally groups that were pastoralists retained lactase and other groups didn't. It's why most east asian don't have lactose tolerance but Mongolians, some Sub-Saharan Africans, and Europeans do.
I've read that before, but I guess what strikes me as odd is how it wasn't until I hit my 30s that I suddenly started shitting my brains out whenever I consumed more than a small glass of milk. I drank a lot of milk growing up...it was pretty much that or water much of the time, and even after I went off to college and stuff I still went through a gallon by myself every 3 or 4 days. Not even just milk but WHOLE milk...I didn't switch to skim until my 20s when I moved in with my gf and she hated whole milk.
Anyways, after three decades of no issues whatsoever, and zero change in my habits, suddenly my body decided "NYET! NO MORE!!!" and my ability to properly digest lactose evaporated basically overnight. I didn't even make the connection until I was traveling and wasn't drinking any milk on my trip and didn't have any problems, but then got nearly crippled the next morning after I had a big ol bowl of Captain Crunch before bed the night I got home.
There's no way our bodies are "supposed" to be. There's the way they are and the way they were. Also some brave and dedicated individuals can apparently overcome lactose intolerance through exposure therapy. Basically they eat a bunch of dairy every day for weeks until their gut biome readjusts to digest lactose without all the discomfort. Apparently the gas and bloating are caused by the overgrowth of some bacteria and it just takes some time to find a new equilibrium so you don't get big blooms every time you eat lactose.
Same, buddy. It was the milk for sure.
It was ice cream for me
