If the human body be likened to a steam-engine, its wastes correspond to the ashes.

Retention of Body Wastes

The injury which comes from the retention of the body’s waste products is of the greatest importance. The intestinal contents become dangerous by being too long retained, as putrefying fecal matter contains poisons which are harmful to the body. Abnormal conditions of the intestines are largely responsible for the common headache malady, and for a generally lowered resistance, resulting in colds and even more serious ailments. Constipation is extremely prevalent, partly because our diet usually lacks bulk or other needed constituents, but partly also because we fail to eliminate regularly, thoroughly, and often.

Constipation, long continued, is by no means a trifling matter. It represents a constant and cumulative tax which often ends in very serious consequences.

Water-Drinking

Free water-drinking when the stomach is empty, especially before breakfast, is beneficial in constipation. Free water-drinking at meals may prove constipating. Excess of water should be avoided by the very feeble or those suffering from heart trouble or dropsy.

Laxative Foods

The best regulators of the bowels are foods. Foods should possess sufficient bulk to promote the action of the intestines and should contain a due amount of laxative elements. Foods which are especially laxative are prunes, figs, most fruits except bananas, fruit juices, all fresh vegetables, especially greens of all sorts, wheat, bran, and the whole grain cereals. Oils and fats are also laxative but can not be used in sufficiently large quantities to produce very laxative effects without producing loss of appetite. Foods which have the opposite tendency are rice, boiled milk, fine wheat-flour in bread, corn-starch, white of egg.

Bran and Agar-Agar

The use of wheat-bran in cereals, in bread, and even in vegetables is a preventive of constipation, as is also the use of agar-agar, a Japanese seaweed product. This is not digested and absorbed, but acts as a water-carrier and a sweep to the intestinal tract. It should be taken without admixture with laxative drugs.

Mineral Oils

Paraffin oil is especially good as an intestinal lubricant to assist the food to slip through the intestinal tube at the proper rate of progress, provided the oil is first freed, by long-continued shaking with water, from certain dangerous impurities. Many refined preparations are on the market for use in constipation. Underweight people should not use these oils unless properly prescribed by a physician.

Avoiding Drugs

It is advisable, in general, to avoid cathartics except under medical supervision, since certain drugs are often very harmful when their use is long continued and the longer they are used the more dependent on them the user becomes. Laxative drugs, even mineral waters, should never be used habitually.

Enemas

The occasional, but not habitual, use of an enema (with warm water followed always by a second enema of cool water, to prevent relaxation) is a temporary expedient.

Massage of the Colon

Massage of the abdomen, deep and thorough, with a creeping movement of the ends of the fingers on the left side of the abdomen from above downward, also promotes the process of defecation.

The normal man and woman should find no difficulty in having complete movements regularly two or three times a day by merely living a reasonable life, being careful especially to avoid overfatigue, to include sufficient bulk in the food, to take regular exercise, including, in particular, breathing exercises, and to maintain an erect carriage.

Low Seated Water Closets

High-seated water closets, so often found in institutions, hotels and private houses, often favor constipation, as they do not permit of the proper physiological attitude in defecation. They prevent the individual from exercising abdominal pressure so essential for this function. Such seats should be made much lower than they are, or the feet should rest on a foot stool, in order to attain the proper attitude for thorough emptying of the intestine.

Number of Defecations

Observations on the manlike apes show that they defecate three or four times a day. Few of the human family have such ideal movements. Millions are conscious of some shortcoming in this regard, and doubtless millions more suffer from some shortcomings of which they are not conscious. Many believe they have free movements when actually they are suffering from a sluggishness in the rectum and other parts of the lower intestine. A rectal examination often reveals unsuspected fecal residues.

Establishing Proper Habits

The natural instinct to defecate, like many other natural instincts, is usually deadened by failure to exercise it. Civilized life makes it inconvenient to follow this instinct as promptly as, for instance, a horse does. The impulse to go to stool, if neglected even five minutes, may disappear. There are few health measures more simple and effective than restoring the normal sensitiveness of this important impulse. It may require a few weeks of special care, during which cold water enemas at night, following evacuation by paraffin oil injection, may be needed. It would be an excellent rule to visit the closet immediately after the noon and evening meals, as faithfully as most people do after the morning meal, until the reflex is trained to act at those, the most natural, times for its action.

Before leaving the subject of intestinal poisoning, we may here again mention the importance of avoiding the poisoning which comes from too much protein. This poisoning is probably due largely to the decomposition of protein in the colon.

Use of Sour Milk

One proposed method for reducing this decomposition of protein is through the use of sour milk. Lactic acid, the acid of sour milk, constitutes a medium in which putrefactive germs do not thrive. Hence, if sufficient sour-milk germs can be kept in the intestines to constantly manufacture lactic acid, putrefaction will be reduced. But, as Professor Rettger and others have shown, the mere swallowing of a little sour milk or of sour-milk tablets is seldom sufficient. The “good germs” swallowed die of starvation before they do much good. To keep them alive and enable them to multiply, we must feed them. The free use of milk and of milk sugar, a little raw starch, or partially cooked cereal such as Scotch brose (oatmeal cooked only ten minutes) will feed the germs.

Evidences of Injury

The odor and character of the stools are indicative of the extent to which our diet is injuring us. The odor is less offensive if the diet is low in protein and thoroughly masticated.
