Why Is The Sigmoid Colon So Vulnerable?
The sigmoid colon is the most common site where diverticulosis occurs. There is a reason why. The human colon is designed with squatting in mind. It has built-in natural obstacles to help maintain continence, ie: to prevent the accidental release of waste. One of these obstacles is the natural kink (bend) where the sigmoid colon joins to the rectum. This kink must be ‘released’ to enable waste to flow to the rectum without restriction. The opening up of the kink can only happen in the squatting position, when the left thigh – pressing against the abdomen – supports and lifts the sigmoid colon upwards. There is also another natural obstacle that lies between the rectum and anal canal (see diagram below). This second kink is formed when the puborectalis muscle – in the sitting position – grips the rectum in the choked position. However, in the squatting position, the puborectalis muscle relaxes its grip to release the kink and straightens the final pathway to the anus so as to allow wast
