I've been following this thread about tortuous colon since I was diagnosed after a colonoscopy fall 2021. The symptoms seem to come and go but mostly show up as a combination of constipation/bloating and diarrhea. This is what I believe is happening - I'm rehearsing it here before I run it by my internal medicine doc.

The tight bend in the colon blocks stool from getting through (constipation/bloating) and then when slightly loosened a watery stool gets by (diarrhea). The pain comes when it is mostly blocked. Miralax for the constipation just makes the diarrhea much worse. I am fairly small (110#) and narrow. My hips and hip flexors are tight in spite of 3x weekly yoga and lots of walking. The descending colon is right behind the hip flexor and psoas muscle runs through there somewhere too. A pelvic floor specialist has me doing hip openers to stretch the area and also self-massage of the transverse to descending colon. I've been doing all these things and still have episodes of pain and bloating. A physical therapist I am seeing for structural pelvic imbalance which causes me hip/pelvic and leg pain, tried reflexology (foot massage) on the side of the descending colon and I got some relief which lasted only 1 day. Some of this is bound up with stress and anxiety so I take a hot bath (when I have time) and rest and relax. It seems there is no easy answer but I will check out the diet mentioned. Thanks!
