First let us consider the unlawful demand made by one or the other organ within the pelvis for more space than rightfully belongs to it. Girls very often from want of thought, and from ignorance of the gravity of results which such carelessness may lead to, neglect the regular evacuation of the bladder and bowels, and the result is from the fulness of the bladder long continued, a pushing of the uterus backward which may, if the habit be kept up, result in permanent displacement. On the other hand, from a neglect of the bowels, a full rectum may force the uterus forward and downward. If this carelessness is persisted in, a displacement becomes a permanent condition, and a consequent adhesion of the walls of the uterus to the neighboring organs often follows. This, as you can readily see, will make serious difficulty for the uterus when performing its functions in pregnancy, and brings on many nervous troubles which greatly affect the entire organism. The womb too, by its false position, crowds the blood vessels of the pelvis, and thus interferes with the circulation of the pelvic organs and all parts below. Added to this it interferes with the portal circulation,—or circulation through the liver,—and thus disturbs the distribution of blood in the digestive organs, and all parts supplied by the blood-flow through the liver. For this reason, you can readily understand how many stomach troubles may be caused by wrong conditions in the pelvis. As the bladder and rectum are capable of great distension, when full they allow little space for the womb. If when distended these organs always pushed the uterus upward, the displacement would cause less serious results; but on the contrary, from the natural position of all the organs, when crowded, the tendency is downward; especially is this so as the result of a neglected and distended rectum, which causes the prolapse, or falling of the womb with all its attendant ills. And the evil does not always stop with this organ alone, but may lead to grave bladder difficulties, and to hemorrhoids and other rectal diseases. The abdominal cavity, or space between the diaphragm above and the pelvis below, has also sufficient room for all the organs located in it, but this cavity too is abused, by faulty dressing, and not only are the contents of the abdomen compelled to suffer; but by their being crowded downward the contents of the pelvis are encroached upon, and the ills I have already alluded to in the pelvis are further aggravated. So much for the knowledge of the physical needed by the young wife, and this is but a beginning. In a book of this compass scarcely more than hints can be given. Every young woman before entering into marriage should have at least a fair knowledge of the following subjects. 1. The human organization, the various organs which compose it, and the functions of each. 2. The care requisite to the healthy maintenance of these organs, and the food required to nourish them.
