I had a rectal bleeding episode in 2016 and another one in November 2019. A colonoscopy performed on February 4, 2020 confirmed a diagnosis of diverticulosis.
I came across an alarming article about research that showed that calcium channel blockers used for high blood pressure such as amlodipine, which I have been taking, have a direct link to diverticulosis. I haven’t changed anything yet, but I’ll for sure ask my doctor if I could try another medication for blood pressure.
