Is colon hydrotherapy safe or is it better to get fleet?

Neither: You are 38 and female. You are curious as to the benefit of colonic hydrotherapy or fleets enema. Ideally in your age group neither unless your doctor diagnosis you with a colonic problem. If you are constipated chronically then see a doctor. The bacteria in your colon are important so washing them out is not advised. Watch your diet, drink plenty of water.
