My poop is narrow short sections and always feel like i haven't when enough no matter how long i sit. feels as if something is still in my rectum area?

A new phenomenon?: If this has been present for many years, you may consider eating more fiber in your diet (reduce the carbohydrate intake and more vegetables or fiber supplement). If this is a new problem, then you need to see a gastroenterologist to get an examination as soon as you can.

Colonoscopy: you will need a complete examination including rectal exam with colonoscopy to r/o mass causing colonic obstruction. please see your health care provider immediately.
