Five months ago I had colonoscopy. Since the 'clean out' of my bowel I have not formed a stool. The motion is very floaty (much less dense than water) and flocculant, often taking four flushes to clear the toilet bowl. It is not diarrhoea like though. It is even in colour with no undigested food or excess fat in it. I know this is a fairly common experience among people and I will make an appointment with my local doctor, but I would like to know more about what the Medical profession knows.
