Colon hydrotherapy is another term for colonic or colon irrigation. Colon hydrotherapy is an important technique of colon cleansing which may enhance the ability of your colon to absorb minerals, vitamins, and other essential fatty acids.
Some people develop serious constipation problems. The common causes for acute constipation include:
1) excessive consumption of processed foods
2) low intake of water
3) sedentary lifestyle, and
4) prolonging the urge to defecate regularly.
Waste that is not removed may accumulate on the walls of the colon. It may, over time, harden and form a layer on the wall which can reduce the efficiency with which your colon passes important minerals and water into your body, which could cause some health problems.
