We saw that in some women menstruation runs a perfectly smooth course, free from any disagreeable symptoms. The same is true of pregnancy. It is remarkable how smooth and easy the entire course is with some women. Many women know that they are pregnant only because of the non-appearance of the monthly periods; and even in the later months they feel no discomfort, attending to all their work and pleasures as usual; and even childbirth is a trifling matter with them. Unfortunately the number of such women is not very large, and, because of our confined, unnatural, often exhausting way of living, is becoming smaller and smaller. There is no question that the civilized, refined woman has a harder ordeal in pregnancy and childbirth than has her primitive sister. We confidently hope that this will not be so in the future; we expect the time to come when true hygiene will be an integral part of the education and the life of every girl, and then pregnancy and parturition may become even easier processes than they are in the primitive races. But the time is not yet; and in the meantime our young women have a good deal to go through. =Morning Sickness.= One of the commonest disorders of pregnancy is the so-called morning sickness. This consists in a feeling of nausea and vomiting, which comes on soon after getting up. The morning sickness makes its first appearance in the third, fourth or fifth week of pregnancy and lasts usually until the end of the third or fourth month. In some women, however, the morning sickness comes on in a few days after impregnation has taken place, and those women diagnose their condition unmistakably by the feeling of slight nausea which they experience on getting up. Medicines are as a rule of little use in treating morning sickness. The "disease" can be relieved but not cured. The patient should stay in bed later than usual, should have her breakfast in bed, and then not get up for about half an hour afterward. If the patient is anemic, a good iron preparation may prove useful. =Pernicious Vomiting.= The vomiting of pregnancy sometimes becomes so severe and uncontrollable that it has been given the name pernicious. The patient is unable to retain any kind of food, not even liquids, vomits almost incessantly, and may become very much run down and exhausted. The vomited matter may contain blood. For this condition a competent physician must be consulted, for in some cases the patient's life may be in danger and an abortion has to be performed.
