I have not had to deal with this myself except perhaps for a weird bowel week when my thyroid was out of whack. For the whole of my life I have battled big D, which has gotten a lot better since I changed my diet. Gluten is not my issue but I have multiple food intolerances as does daughter.
Daughter has also battled big D but also constipation. Some years back she kept getting UTIs. She went to two different specialists for this who could not find a cause for the problem. But a Dr. at the walk in clinic did. From here on out she shall be known to us as Dr. Bowels. Her real last name is actually quite similar. Heh.
What this Dr. found a few years ago via an X Ray was that daughter was full of poop. That in turn prevenented her from urinating fully. Some of the urine stayed in there and eventually she got an infection. That and that caffeine was cauing irritation.
Currently no UTIs and she has resumed caffeine, even drinking coffee. She is 15 now. But she has also been suffering from some acne. She is seeing a dermatologist for that.
But recently? Her face got super bad. As in clusters of pimples on clusters of pimples. Nothing helped.
Then she got big D again. Said that her stomach hurt badly and she was sleeping a lot. Gastro Dr. thought it had to be some other food intolerance that we hadn't ferreted out. But, no! Back to Dr. Bowels. This time she found again via X Ray what she said was at least 4 feet of backed up stuff, stuck in her colon. Said this had been going on for weeks! Because it was so impacted, the only thing that could get through was liquid, hence what appeared to be big D. Said she just has slow digestion and it is genetic. Will need to take Miralax daily for the rest of her life.
Started her on that. Today was the 4th day. Am not sure she got all the gunk out of her but enough to where she isn't totally miserable and now her face is totally cleared up!
I had assumed that her face had gotten bad from stress but now I am wondering if maybe she was just toxic? She had also lost a lot of hair. She has really long hair and I would have to ream out the shower drain daily because there was so much in there. That seems to be better with increased vitamins and supplements. She also went on a vegetarian diet at the end of July and has been really good to stick to it. I have been trying to find ways to get more protein into her but... She has been super good with the fiber, making the switch to brown rice and eating lots of beans, salad, potatoes with skin and popcorn.
So... Could the constipation have caused the pimples? Odd that her face was so bad and then after three doses of the Miralax it has cleared right up.
