Contamination of Small Intestines...What Has Your Toilet Got To Do With It?

Up to 70% to 80% of people in the West had fecal contamination of the small intestines.

This was the finding by Dr William Welles, a Chiropractor, Nutritionist and Kinesiologist in California.

In his article The Hidden Crime of the Porcelain Throne, Dr Welles identified the underlying cause: sitting toilets.

It makes for fascinating reading -- how using the sitting posture for answering the call of nature could lead to small intestine contamination.

But first, a little bit about the small intestines. It is the part of the digestive tract (begins in the mouth and ends at the anus), where the body absorbs most of the nutrients from chyme.

digestive system

Chyme is food in the stomach that is partly digested and mixed with stomach acids. It enters the small intestines and is moved along by muscular contractions called peristalsis. It is in the small intestines that further digestion takes place and nutrients in the chyme are absorbed by the body.

Leaving the small intestines, the digested food enters the large intestines or colon. As it travel through the colon, water and salts are continuously extracted, and it reaches the rectum as solid waste, which is temporarily stored before being excreted through the anus.

In short, the small intestines and colon perform very different functions, even though they form part of the digestive system.

One deal with food and nourishment; the other process waste…

For this reason, the contents in the colon and the small intestines must be kept separate, and not come into contact with each other.

If waste in the colon were to leak into the small intestines, it would contaminate the food contents in it, with disastrous consequences…

How Nature Solves The Problem

To prevent contamination, Nature has put a special valve called the ileocecal valve at the beginning of the colon (cecum).


The colon is divided into 6 parts: the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. The cecum is shaped like a pouch to receive the digested food flowing in from the small intestines.

The ileocecal valve acts as a one-way colon inlet valve. It is designed to allow digested food in the small intestines to enter the cecum, but prevent waste in the colon from going into the small intestines.

There is one thing though…

The ileocecal valve is designed
with squatting in mind…

In the squatting position, the right thigh - pressing against the lower right abdomen - supports and squeezes the cecum from below.

The squeezing action forces the wastes in the cecum upwards into the ascending colon, to be carried away by muscular intestinal movements (peristalsis), and away from the ileocecal valve (and appendix).

The effect is the same as squeezing a water-filled balloon from below...
By forcing wastes away from the ileocecal valve (and appendix), the action of the right thigh keeps the valve securely closed (and appendix clean). There is no risk of waste from ever seeping or leaking into the small intestines.

The Danger With Sitting Toilets

Sitting toilets puts the ileocecal valve at risk.

In the sitting position, the cecum – and ileocecal valve - is deprived of support from the right thigh.

Without the squeezing action, the waste contents in the cecum are not given a beneficial push in the right direction, ie: upwards into the ascending colon. The waste could stagnate, and the continual drying process can cause it to become dry and adhere to the walls of the colon…

Also, in the sitting position, the ileocecal valve is subjected to unnatural pressures which can overcome its ability to block waste from entering the small intestines…

The colon has natural built-in obstacles (in the form of bends) which can only be released in the squatting position. In any other position, the colon is in the continence mode as the natural obstacles are not released.

In this mode, elimination is difficult, often requiring straining and 'pushing' downwards with the diaphragm while holding the breath - the Valsalva Maneuver.

The Valsalva Maneuver results in the build up of pressure acting downwards against the pelvic floor, colon and hence cecum... It is like squeezing a tube of toothpaste (colon) in the middle, which causes the bottom of the tube (cecum) to inflate.

The ileocecal valve, lacking the support and protection of the right thigh, can be overwhelmed by this pressure and give way… when this occurs, wastes in the colon enter the small intestines, with disastrous consequences.

The failure of the ileocecal valve - as a result of wrong toilet posture - is the ROOT cause of intestinal and digestive tract problems.

Dr William Welles, the Chiropractor, Nutritionist, and Kinesiologist mentioned earlier, wrote about this phenomenon in his article The Hidden Crime of the Porcelain Throne:

"My discovery of a dysfunctional ileocecal valve in approximately 80% of my patients is also confirmed by modern medicine.

The ileocecal valve is so commonly found to be dysfunctional in surgeries of the bowel and in barium enema studies that it is believed to be inherently faulty in its design."

Drawing on the research of F.A. Hornibrook, Dr Welles suspected that the faulty design responsible for this problem was not Nature's, but Man's.

Hornibrook had stated that the design of the Western toilet defied the laws of it forces the user to bear down without the natural support to the abdominal walls provided by the thighs (when one is in the squatting posture).

Dr Welles then verified his hypothesis by conducting muscle tests. This was his finding:

"When individuals sat in the position encouraged by the western toilet and bore down so as to eliminate fecal matter, the muscles weakened immediately and the ileocecal valve was blown out...

The ileocecal valve is critical to proper intestinal plumbing, and its dysfunction is the root cause of many of the diseases of modern civilization..."

In his article, Dr Welles also discussed other ailments caused by sitting toilets such as colon cancer, hemorrhoids, hernias and pelvic organ prolapse.

He concluded with some strong words of advice:

"Cast aside your preconceived ideas as to what is normal and use your rational mind to act on what has been stated above. At any given time in history it is possible to look back and find great faults with the habits of previous civilizations.

I believe that future generations will one day look back at our aberrant habit of using the modern toilet ... and cringe."


The immense pain and suffering associated with diseases arising from contamination of the small intestines (also known as Crohn's Disease) is totally unnecessary.

Yet, it is not going away anytime soon. There are two reasons: the widespread use of sitting toilets, and the lack of knowledge about the role of the ileocecal valve in preventing waste and food from coming into contact with each other.

The truth is that the best way to prevent contamination of the small intestine is to squat instead of sit for waste evacuation. But don't wait until it is too late... the longer you continue to sit for bowel movements, it would become more and more difficult for you to squat, as explained on this page about squatting facets.

It might take you quite a while... but with practice and patience, you can regain the ability to squat. That would then allow you to make the switch from sitting to squatting for life.

It is so simple and basic. Yet, by choosing to squat instead of sit for emptying your colon, you stand to reap a lifetime of health dividends.

The best way is to install a squatting toilet. If this is not possible, the alternative would be to use a toilet squatting platform or converter.
