Not every fasting programme includes a colonic irrigation. The purpose of completely emptying the bowel is to rid it of any food residue that could impair the success of the fasting therapy. If, however, you decide on an alkaline fasting therapy, for example, which involves a very gentle detoxification, a colonic irrigation is not absolutely necessary. However, many people report a pleasant feeling after the colon flush and even a reduced feeling of hunger. Don’t be afraid to give a try.
