Unlike the other pressure symptoms, shortness of breath is ordinarily aggravated by the recumbent posture, for lying flat on the back increases the compression of the chest. At night, which is frequently the time when difficulty in breathing is most pronounced, the patient may, if necessary, sleep propped up in bed. For this purpose an appliance called a back-rest may be used, but an extra pillow under the head and shoulders is usually sufficient.
LEUCORRHEA.—The meaning of the white discharge from the vagina known as leucorrhea is variable: at times it indicates the existence of an ailment requiring treatment, and at other times it does not. To be on the safe side, therefore, anyone who is troubled by leucorrhea should obtain her physician's opinion as to its significance.
Normally, as we learned in Chapter V, there is an increase in the vaginal secretion during pregnancy; but this fact is rarely noticeable until the latter months. Usually it is pronounced only during the last few weeks. At that time, owing to its antiseptic qualities, this pale white fluid should not be disturbed by the use of douches. In the early months of pregnancy, however, leucorrhea may cause such inconvenience as to demand medical treatment.
While itching is the most disagreeable effect of such a vaginal discharge, it should be known that itching is not always due to leucorrhea. Thus it may be caused by a highly concentrated urine, and in that event will be relieved by drinking a larger amount of water; or it may be due to the presence of unusual constituents in the urine. Skin diseases also cause itching; and light haired people, since they have more delicate skins that brunettes, are especially susceptible to these ailments. To such skin affections soap and water may be very irritating; so that when they exist it is often advisable to cleanse the parts with olive oil. In other cases, ointments are required and will be prescribed by the physician.
Itching of the skin over the extremities or over the whole body, it is clear, cannot be attributed to leucorrhea, but in these very rare cases the irritation would seem to be caused by some waste product which is being eliminated through the sweat glands. We do not know what the substance is, but, as the symptom appears so seldom, it must be due to an unusual kind of waste product or else to one whose elimination normally occurs through other channels. The affection of the skin thus brought about is really a very mild kind of poisoning, and since the offending substance arises in the body of the patient herself the condition is called an autointoxication. Effective treatment consists in drinking water freely and taking a cathartic, for the one stimulates the kidneys and the other the bowels to assist in getting rid of the cause of the trouble.
TOXEMIAS.—In order to understand what are known as the toxemias of pregnancy, we must remember that the nutrition of our bodies involves three separate and distinct sets of processes. What we eat is, in the first place, digested and absorbed into the body; secondly, the products of digestion are utilized by the tissues; and, finally, the waste material is thrown off from the body. Any one of these processes may be carried out in a way that is not consistent with health. Most of us realize that disturbances may occur in the course of digestion, and we are also aware that the excretory organs occasionally fail to do their work in a satisfactory way. But what laymen, perhaps, do not appreciate is that the intermediary steps— between the time when the food is absorbed and the time when the waste material is finally eliminated—may not be taken precisely as health requires. Of course, any person may be the subject of one or another of these nutritional disorders, but unquestionably such disorders are somewhat more frequent during pregnancy than at other times. Nor is this difficult to understand, for the nutritional processes of two beings are here linked together. They generally proceed harmoniously, but if they do not there results an autointoxication of the mother which is called a toxemia.
Such toxemias, with extremely rare exceptions, do not occur in the early months, but are associated with the period of the active growth of the fetus, namely, the second half of pregnancy. For this reason, and for some others which do not concern us here, it seems probable that the nutritional processes of the child are primarily responsible for these ailments. This view, however, must be somewhat modified, for experience has clearly taught that the efficiency with which the maternal excretory organs do their work has a great deal to do with the effect that the fetal waste products have upon the mother. On this account she has been urged to pay attention to personal hygiene. It is also necessary, however, that she should become acquainted with the symptoms which give warning that the excretory organs are acting imperfectly.
Autointoxication can almost always be prevented. The means of prevention are neither mysterious nor difficult to carry out; they lie within the power of every prospective mother, for they consist merely of what has already been discussed, namely, the intelligent regulation of the diet, the care of the body, and a correct ordering of the daily life. To the chapters dealing with these subjects reference should be made and particular attention should be paid to what has been said concerning:
(1) Wearing suitably warm clothes, (2) Bathing regularly, (3) Taking a proper amount of exercise, (4) Drinking water liberally, (5) Avoiding an excessive quantity of meat, (6) Guarding against constipation.
At present the value of prevention in the treatment of the toxemias of pregnancy is so clearly recognized that charitable organizations employ nurses to visit women of the poorer classes during pregnancy in order to instruct them about the measures that I have just indicated. Remarkable results have already been obtained. In one clinic where this method has been adopted the frequency of all kinds of toxemia, I am told, has notably diminished, and serious types are not permitted to develop. Similar results should be obtained in private practice when patients place themselves under medical supervision at the beginning of pregnancy. Under these favorable circumstances symptoms of autointoxication probably occur not oftener than once in every hundred pregnancies, but nine out of ten of them, being promptly recognized, yield readily to relatively simple treatment.
