As stated in a previous chapter, the first unwelcome visitor, in infancy, is inflammation of the integument and mucous membrane of the anal orifice, invited by the uncleanliness involved in the use of diapers; and this visitor takes up its residence slowly along several inches of the lower bowel. Its first symptoms are likely to be constipation, flatulency, colic, indigestion, bacterial and other poisons, occasionally diarrhea, and the usual general disturbance of the system as above detailed. It is admitted by all authors that inflammation of the anus, rectum, etc., is by far the most common disease that afflicts mankind at all ages; and I maintain that the natural result of such inflammation is a more or less extensive occlusion of the lower bowel, which in turn involves an undue retention of the feces, and thus we have the foul intestinal canal and stomach called gastric and intestinal indigestion. The wrong treatment of constipation, diarrhea, indigestion and auto-intoxication up to the present time has been due to improper diagnosis. Writers on these subjects speak of them as causes when they are merely symptoms. And the remedies for these "causes" are even more numerous. _Mistaken diagnosis on the one hand, measured doses on the other, and there you have the scientific doctor!_ The primary cause, inflammation, like the original spark applied to dry shavings, sets up morbid changes in the various parts of the digestive canal and the other organs of the body, and these "set up" or established changes are properly secondary or derivative causes accompanied by their own symptoms. The primary disease and symptoms may exist for five, ten, twenty or more years before any pronounced secondary or derivative diseases and their symptoms occur or are noticeable to a sufficiently marked degree. The chronic character of the malady, and the complication of primary with secondary diseases and their symptoms, have thoroughly disconcerted the doctors. Hence the many "causes" assigned for indigestion, constipation, etc., and the many kinds of remedies prescribed with the one sure result, FAILURE; and hence, also, not a few of the self- and drug-intoxicated ones dubbed, or actually developed into, hypochondriacs. Diagnosis wrong, treatment wrong, failure certain, and the foulness of the intestinal canal continued! This is the experience and testimony of the many, many sufferers from the most common malady that afflicts humanity from infancy to old age, and which will continue to afflict the great majority until it is properly understood and treated.
