Emptying the Bowel

Step by step description of what happens when you sit down or Squat to go.
Removal of clothing
2. Assumption of Squatting or sitting posture.
3. Initiation of Defecation by STRAINNG (not necessary in squat posture) and RELAXING the EXTERNAL ANAL SPHINCTER.
4. Defecation
5. Urination
6. Farting—this indicates the end of the process of defecation.
7. Wiping, Cleansing or Washing.

Defecation is the process of emptying the bowel of FAECES—waste material from the digestion of food and other bodily functions.

Defecation involves the co-ordinated involvement of:
1. The pelvic floor and abdominal muscles
2. Colonic motility
3. Posture adopted during the process—squatting is more efficient and safer than sitting
The process of defecation can only begin when the digestive process has been completed and the residue enters the Cecum, at the beginning of the Colon.
The undigested mass of matter travels upwards into the ascending colon, where most of the water and Electrolytes in the faeces is re-absorbed.
Only the water retained by the fibre, mucus and Bacterial cells remains.
The final consistency of the Faecal mass depends on the time it takes for the progress of this mass towards the transverse colon, sigmoid colon and finally the rectum.

The longer it stays in the colon, the more water is re-absorbed and more fermentation may take place by Bacterial action on the wastes present.
The longer faeces stays in the colon, the drier the stool gets and can lead to the problem of CONSTIPATION.


The faecal mass does not enter the rectum from the sigmoid colon until the act of defecation is about to occur. The Rectum is only for temporary storage of waste.

The storage of faeces is within the sigmoid colon. The faeces move into the rectum due to a massive peristaltic movement, which is a propelling motion set up by the muscles.
The DESIRE or URGE to defecate is initiated by a distention or stretching of the rectum by the entry of faecal mass caused by the massive peristaltic wave.
If defecation does not follow, the rectum again relaxes and the desire or urge to defecate does not return until more faecal matter enters the rectum and distends it further.
The final act of expelling the faeces can be controlled and regulated through a conscious use of the related musculature that make up the SPHINCTERS or locks at the junction of the anus and Rectum (puborectalis), the internal Anal Sphincter and the external anal sphincter.

It is this control which we refer to as “Toilet training”, that every child is required to learn.


This VOLUNTARY or conscious and controlled phase consists of
1.Contracting the diaphragm and the muscles of the abdominal area—commonly known as STRAINING. (VALSALVAS manoeuvre)
2. Assuming a doubled over or squatting posture so that the thighs provide support or resistance to the abdominal wall, and thus permit a greater intra abdominal pressure to initiate the peristaltic wave essential to move waste down the gastrointestinal tract.
3.Relaxing the external anal sphincter muscle that controls the opening of the anal canal.
Normally, the anal canal is totally collapsed by the contracted sphincter and the anus is merely a slit. Control of this sphincter muscle is Vital to finish the defecation process.


Factors that may affect this conscious control of Defecation:

1. Fright, Anxiety, Stress, Depression

2. Change of routine—Travel, Away from home, unfamiliar Bathroom, Time zones, “Jet lag”

3. Change in eating habits and meal times
How to heal and prevent Bowel disorders
Diet is not about what you should NOT eat, it’s about what you should include in the diet that matters.
As long as your diet includes the correct balance of plant foods containing soluble fibre, insoluble fibre and resistant starch your colon will produce the perfectly formed stool. The important next step is to evacuate this stool without straining so that the body does not suffer from the pressures created each time the bowel is emptied.

In order to heal and prevent bowel disorders you need to make lifestyle changes that last the rest of your life time.

Include more fluids and plant food containing soluble fibre, insoluble fibre and resistant starch in the diet so that the perfectly formed stool will be made in the colon and beneficial bacteria will flourish and eliminate disease causing bacteria and fungi.

Evacuate the perfectly formed stool by adopting the squat posture to eliminate the need to strain during bowel movements.

It is not possible or safe to squat on the modern raised toilet seat installed in all western homes and it is impossible to squat for any length of time if you have not done this from childhood onwards. This makes the use of any raised platforms impossible to adapt to.

The SquattLooStool is designed to allow you to adopt the squat posture while seated comfortably on your raised toilet seat.
The single best and easiest lifestyle change you will ever make, leading to a healthier body.
