In his book Colon Health, Dr. Norman W. Walker states flat out that everyone should have as many colonics as it takes to clean the entire length of the colon. The purpose is to avoid premature aging, disease, as well as unwanted surgical procedures that can permanently alter your life. The human colon is on average 5 feet in length, and 3 inches in diameter (or 1.5 meters long with an approximate average diameter of 7cm). This large surface area, coupled with constipation and hardened impactions along the bowel wall, make it impossible for the water that is introduced into the colon during a single colonic treatment, to reach the entirety of the large bowel. Only one part of the colon can be cleaned at a time, and those areas closest to the anus and rectum must be cleared of obstruction first, before deeper areas of the colon can be accessed.
The colon is also known as the large bowel or large intestine. It is an organ that is part of the digestive system (also called the digestive tract) in the human body. The digestive system is the group of organs that allow us to eat and to use the food we eat to fuel our bodies. The colon is about 5 feet long and about 3 inches in diameter. Many facets of modern life such as too much stress, too little sleep, eating a diet of processed and high-sugar foods, and taking antibiotics can all damage our gut microbiome and colon health. This in turn may affect other aspects of our health, such as the brain, heart, immune system, skin, weight, hormone levels, ability to absorb nutrients, and even the development of cancer. There are a number of ways an unhealthy colon might manifest itself.
