The colon wall weakens, forming little pockets that push out into the side of the bowel. New fecal material passes by the old, which lodges in the pockets to rot and irritate the colon. Inflammation of the mucous membrane lining of the intestines that leads to both diarrhea and constipation. Sometimes muscular spasms in the colon cause constipation. This makes the elimination pattern erratic, with alternating periods of diarrhea and constipation.
Constipation is more likely during stressful periods.
Straining to eliminate hard, dry fecal material can irritate the rectum and give rise to hemorrhoids. Toxic material in the colon can inflame the lining. If you have any doubt that this material is injurious to the body consider a little baby and how you have to keep its diaper changed. If its bowel movement sits too long against its tender skin, the skin becomes red, irritated and inflamed. The body is pushing it out because it is toxic and irritating.
