Attention or inattention to the mother's own hygiene during pregnancy has great effect on the fetus, and care of hygiene may avert abortion. The woman's dress should be simple and warm enough to prevent congestion from changes in temperature. Congestions are likely to affect the kidneys, and care of the renal function is always one of the most important facts connected with pregnancy. No circular constrictions of the trunk by lacing or stiff corsets should be attempted. The corset forces the uterus and child downward into the pelvis and against the lower abdominal wall, causing congestion of the pelvic veins and strain on the abdominal muscles. Tight corsets, preventing the expansion of the uterus and the growth of the fetus, may cause mutilations like club-foot and wry-neck, or even kill the child. The woman who would "preserve her figure" by corsets, to the mutilation, weakening, or killing of her unborn infant, and this is an every-day evil, is either a criminal fool or an unmitigated scoundrel. Tight lacing to conceal pregnancy is a method of murder. High-heeled shoes are somewhat injurious because of the constrained position into which they throw the woman. X-ray photographing of pregnant women is very likely to cause abortion. The woman's diet should be simple. She must abstain from all alcoholic liquors even if she has been accustomed to their use at meals. She should not overeat on the supposition that she has to feed two persons. Some popular books advise a special diet to reduce the bone-salts and thus get a smaller baby and one more easily delivered. Such advice is criminal. The constipation of pregnancy is not to be treated by strong cathartics like Epsom salt. The kidneys are to be watched; therefore the urine should be examined every three weeks up to the seventh month, then oftener. If there is any suspicion of toxemia or nephritis, the urine should be examined daily. Obstetricians who have any regard for their own conscience and reputation will have nothing to do with a woman who refuses to take this precaution. Physical exercise should be gentle--say, walking, up to two miles in the daytime. The vast majority of women are too lazy to take physical exercise as a hygienic duty at any time, and during pregnancy their aversion to all effort to overcome indolence is so great they make even themselves believe they cannot. Just as most professional men think they think, most women think they work. There are thousands of women who have servants, yet make not only their families and friends but themselves believe they are worked to death, and their work is the spreading of four or five beds, and the ordering of groceries over the telephone. When these women are pregnant they quit even the bed-making.
