Colonics just weaken my body further. I have a severe magnesium deficiency (which does not respond to oral supplementation). The colonic further upset this electrolyte balance - making my readings dangerously low. My liver enzymes are usually raised on my regular liver function tests (ALT and Bilirubin levels - Gilberts Syndrome) - the colonic made these enzyme levels raise even higher. It was all very worrying - maybe I could just try the Colosan - colonics just seem to be a no no for my situation.
