The constant absorption of intestinal poisons affects the system itself,--the symptoms are headache, neuralgia, loss of appetite, nervousness, insomnia, vertigo, inability to concentrate, lassitude, indigestion. The condition which we name constipation is therefore one of supreme importance. From a medical standpoint, it is the biggest problem in the whole realm of disease. It is the most significant hygienic function of life, and it is becoming more and more important, and more and more a problem. Every modern factor upon which physical efficiency seems to depend is an enemy to the systematic regulation of this function. Our method of hurried and indiscriminate eating, our system of strenuous living, our unsanitary environment, our business activity, our method of pursuing pleasure, take no account of, and resent the time devoted to cultivating, as a hygienic necessity, this toilet requirement. This imperative call of nature is pushed aside by the child at play, by the housewife for a duty which could wait, by the merchant for an engagement. It is particularly an American disease, and it is uniquely an American woman's affliction. It is a curious commentary on the intelligence of the American people, who are ordinarily alert and analytical, to realize how few of them really know how serious a matter constipation is. They don't know because they have given the matter absolutely no thought. They have accepted it as a mere matter of fact, almost of fate. INCOMPLETE CONSTIPATION.--There is a type of constipation that is not known to the average person and not well understood by those few who know of its existence. In this form of constipation there is a daily bowel movement but the movement is not complete. The bowel does not thoroughly empty itself; it has established this habit because of conditions under which it has had to do its work. If a woman neglects herself, becomes muscularly inactive, does not take proper out-door exercise, grows fat and lazy, eats irregularly and indiscriminately,--the bowel suffers with the rest of the system. The woman may have a healthy appetite, may eat the wrong things at the wrong time, yet the bowel is supposed to go on acting rightly, but it does not. It, too, becomes lazy and acquires bad habits, and this form of incomplete constipation is the result. These patients look healthy and get little sympathy for any pains they may have. They may even gain in weight; they get headaches once in a while, and if they go shopping or visiting they don't feel quite well afterward. They are suffering from the effects of chronic constipation, though their bowels are apparently regular. They are marching onward toward apoplexy or Bright's disease of the kidney.
