Has anyone ever had one. Are there any negative side effects?
A colonic will eliminate many of the beneficial bacteria in the colon. This is definitely a negative side effect. I would think twice.
I had to have a colonoscopy last November. The surgeon suspected an aggressive form of colon cancer but found nothing. It turned out that my symptoms were being caused by lactose intolerance.
I found the preparation and the aftermath to be extremely disruptive to my body. You don't want to do anything like this unless it's absolutely necessary.
