Hi there, 15 yrs CIC, treatment resistant, same GI. 17 yrs ago was diagnosed with celiac disease, probably born with it, but asymptomatic. I am gluten free and I have had no improvement in any medical issues (I have oh so many). I can eat gluten and feel normal. Peanut butter- don't eat a lot, but no additional poop issues.
I have used everything: Amitiza, Linzess(helped for a while), Trulance. 2 partial small bowel obstructions that cleared with out medical care, 1 landed in ER, ICU with nasal gastric tube for 3 days. The ONLY THING THAT WORKS IS lots of Miralax, 3-6 capfuls a day, add Metamucil powder (gummies work better for me) 1-2x week. Translation: I keep my poop in almost constant slow liquid and sediment through to full on DIARRHEA. After 3 digital removals is 2 months, done by myself, I am simply terrified of constipation. As with all of us with this problem, I could go on and on.
New 💡: this won't apply to everyone, but 17 years ago when I was diagnosed with celiac, it was my accident. My vitamin D deficiency and PTH-parathyroid was hyper. This has nothing, at all, to do with the thyroid glands. Malabsorption caused by celiac was a part of the problem. But my GI, PCP, and ENDOCRINOLOGIST all diagnosed me as all is good, don't eat gluten. Now, accidentally again, my pancreas showed bad signs...blah blah... I asked my Endocrinologist about it, she focused on my calcium levels trending upwards. Short version, and wrong diagnosis, get 2nd opinion from outside doctor, I have Hyperparathyroidism and I have to have surgery. Elevated calcium levels in blood or urine can definitely be a factor in CIC. Parathyroid.com and swparathyroid.com are excellent sources for this. I've been in this hyper mode for probably 5-8yrs, whether I have benign tumors on the glands or not, my 2nd opinion Dr. said that my parathyroid glands are likely in a permanently damaged condition, which means my glands will keep pushing out calcium even though my body has too much calcium already. When you read the list of typical symptoms/manifestations, you will see that MANY other illnesses have the same symptoms, it is tricky. Just another avenue to look at.
