Thanks for the nifty image of your colon! I have had esophagrams which seem to show a tortuous esophagus. Many in my family as well as myself, have tortuous blood vessels. My femoral arteries, the usual route for cardiac catherization tools to get to the heart, are described as tortuous. Being old at 79, I have more fecal incontinence as well as urinary frequency. Pelvic Floor Therapy with wise counselling by a specialty therapist was very helpful. I now use three Kirkland fiber capsules at night, at least one Medjool date (what a treat) a day, and hope to increase my fresh vegetables and fruits as we welcome Pacific Northwest Springtime garden foods. The National Institutes of Health has a rare condition website with more information about Tortuosity syndromes. Each condition webpage has a reference to an information specialist who can provide more recent information: https://rarediseases.info.nih.gov/diseases/774/arterial-tortuosity-syndrome
