I’m 65, but was actually diagnosed with this condition many years ago. My colon is extremely redundant or long with many loops and twists. Colonoscopy preps and the scopes themselves are always difficult. You will find varying opinions from GI’s and colo-rectal surgeons regarding this condition, at least I have! But most feel it is a result of years of straining from constipation and most, esp “older women” have it. They don’t take it too seriously unless you develop a “kink”. One gi just told me not to get constipated! I found that hysterical as that was the very reason I was seeing him!
Anyway, I’ve found that a “low fiber” works best for me which I know is contrary to everything you normally read. But high fiber foods and supplements tend to “jam up” in those loops. I don’t eat a lot of fresh fruit and veggies other than in smoothies or cooked, mostly eat chicken and seafood. Lots of liquids. I also have very slow motility so I’m on meds for that. Exercise. Add in mineral oil, if needed. Best of luck! Oh, most won’t do surgery for this anymore.
