Thank you for sharing. My new primary physician whom I met last week suggested that during my surgery 5 years ago nerves may have been severed that serve the colon.
That is the first logical explanation I have received since meeting my gastroenterologist.
Like you, I plan when I will take a natural laxative and stay home the next day.
I see my GI on April 4th, I will post what he says. He is rather dismissive. My new PCP put in a request to my insurance for a second opinion referral to a different GI . So frustrating. Like you, I work out, hike, drink lots of fluids, eat fruits and vegetables, etc., etc. Nothing! So frustrating. Doctors don't get how much this changes quality of life.
