The Defecation reflex and the urge to go

The presence of food in the stomach causes distention in the stomach wall which leads to the creation of mass movements.

These mass movements push faeces into the normally empty rectum.

Distention of the rectum stimulates the Defecation reflex.
This is largely a spinal reflex mediated via the pelvic nerves and results in reflex relaxation of the internal anal sphincter followed by voluntary relaxation of the external anal sphincter and defecation.

Faeces propelled from the sigmoid colon to the rectum

>> >>
Resulting distention at rectal wall stimulates stretch receptors or mechanoreceptors that initiate the defecation reflex that empties the rectum.

>>>> Stretch receptors send nerve impulses to the sacral spinal cord. These receptors can discriminate between solid, liquid and gas content and act accordingly.

>>>> Motor impulses from the spinal cord travel along parasympathetic nerves back to the descending colon, sigmoid colon, rectum and anus

>>>> Longitudinal muscles of the rectum contract, shortening the rectum and increasing the pressure within it

>>>> These pressures, along with voluntary contractions of diaphragm and abdominal muscles, plus parasympathetic stimulation, open the internal anal sphincter

>>>> The external anal sphincter is under voluntary control, and if opened, allows faeces to be expelled through the anus.


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.

1. 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.

2. 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.
