The danger of these practices depends upon how much they are used and whether they are substituted for necessary medical care. Colonic irrigation, which also can be expensive, has considerable potential for harm. The process can be very uncomfortable, since the presence of the tube can induce severe cramps and pain. If the equipment is not adequately sterilized between treatments, disease germs from one person's large intestine can be transmitted to others. Yet no license or training is required to operate a colonic-irrigation device.
Colonic irrigation can do no good, only harm.
These ideas are utter nonsense. Ordinary constipation usually can be remedied by increasing the fiber content of the diet, drinking adequate amounts of water, and engaging in regular exercise. If the bowel is basically normal, dietary fiber increases the bulk of the stool, softens it, and speeds transit time. Defecating soon after the urge is felt also can be helpful because if urges are ignored, the rectum may eventually stop signaling when defecation is needed. A doctor should be consulted if constipation persists or represents a significant change in bowel pattern.
