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 normal, dietary fiber increases the bulk of the stool, softens it, and speeds up elimination time. Defecating soon after the urge is felt also can be helpful because the rectum may over time stop signaling when defecation is needed if the urges are ignored. Stimulant laxatives, such as cascara or castor oil, actually stimulate the intestines to contract more forcefully and frequently. However, frequent use can damage nerve cells in the colon wall, decreasing the force of contractions.
Frequent enemas can also lead to dependence.
A physician should be consulted if constipation persists or represents a significant change in bowel pattern. There is often an enhanced self awareness and sense of well being found with short fasts. This is likely due to increased levels of cortisol, a stress hormone made by the adrenal glands. This is a temporary phenomenon. Warm water, often 20 gallons or more , is pumped in and out through the tube, a quart at a time, to wash out the contents of the large intestine.
