The Prospective Mother, a Handbook for Women During Pregnancy

by J. Morris Slemons

The really important changes in the body, other than those pertaining to the uterus, are familiar to women who have passed through pregnancy; but other prospective mothers may not understand that they will regain the bodily condition which existed before conception.

Loss in Weight.—While the weight lost during the lying-in period is not so vital as some other alterations, many have a keen interest in it. In addition to the loss of ten to fifteen pounds at the time of birth, a further loss occurs in the course of a few weeks. Diminution in the size of the uterus is responsible for the loss of nearly two pounds, and the lochial discharge for at least another; but the chief factor concerned is the removal of water from the tissues, many of which have become dropsical toward the end of pregnancy. Altogether patients do not lose less than ten pounds during the lying-in period, and often lose a great deal more. The average loss for the first week alone is said to equal one-twelfth of the patient's weight at the conclusion of labor; the total loss for the whole of the puerperium corresponds to one-tenth of her weight at the beginning of it. Variations from the rule are attributed to individual peculiarities of nutrition. In general, stout women lose more than slender ones, but with all types the loss is greater if the mother nurses her infant. On the other hand, a generous diet tends to counteract any loss in weight whatever.

The Abdominal Wall.—Much more important than the question of weight is the recovery of the abdominal wall from the strain imposed by the enlargement of the womb. In normal cases, to be sure, there is very slight disproportion between the size of the pregnant uterus at term and the capacity of the abdomen, yet the abdominal wall invariably suffers a little stretching and unless it retains its elasticity, the viscera are deprived of essential support, and cause more or less discomfort.

The restorative changes in the abdominal wall involve the skin, the fatty tissues, and the muscles. As soon as the distention has been relieved the skin falls into folds, less noticeable if the pregnancy was the first; and the muscles become so flabby that one has no difficulty in pushing the wall backward until it touches the tissues which cover the spinal column. Within a few weeks, if all goes well, the muscles regain their "tone." Coincidently, the excessive fat over the abdomen is absorbed. The skin becomes smooth, and its pigmentation fades completely; but the pregnancy streaks rarely vanish entirely, although they always become very much less noticeable.

Whether or not the abdominal wall will recover from the distention of pregnancy depends entirely upon the muscles. As the lying-in period advances each fiber should gradually shorten until the whole muscular structure becomes as firm and tight as it ever was. But this takes time, and no artifice can hasten the repair. Perfect recovery is most likely with the body in a recumbent position, which relieves the muscles from any strain. These facts are better appreciated than formerly, hence most physicians encourage their obstetrical patients to remain in bed somewhat longer than their mothers did. Generally nothing else will be required, and only under extraordinary circumstances will nature need assistance. Thus, if there has been unusual distention, as, for example, that due to twins, the muscular impairment may be extreme; or if pregnancies follow one another in quick succession the strain becomes so nearly continuous that there is not sufficient time for adequate repair. Whenever nature does need encouragement calisthenics of some kind are advisable. These systematic exercises, which the patient practices in bed and flat on her back, are usually begun about a week after delivery, though there may be some reason for beginning them earlier or later than this.

The physician will always select the proper calisthenics, but the following "movements" generally prove satisfactory. To exercise the muscles at the front of the abdomen one leg after the other is raised and lowered; as this is being done the knee will be bent (flexed) at first, but later the leg may be held straight (extended). Other muscles come into play when the feet are alternately brought together and separated as widely as possible. A third movement which exercises the muscles at the side of the abdomen consists in raising the shoulders from the bed and twisting the trunk so that the weight of the chest rests now on the right, now on the left elbow. When these movements can be performed fifteen or twenty minutes without fatigue more vigorous exercises may be adopted. For example, the buttocks, together with the lower part of the back, are raised off the bed, while the shoulders, elbows, and the heels remain stationary. A day or so before getting up the patient should practice alternately raising herself from the recumbent to the sitting posture and returning to the above position without assistance from the arms.

The value of bandaging the abdomen immediately after delivery as a means of strengthening the abdominal muscles is questionable; though physicians agree to the advantages of a supporter after patients are out of bed. We constantly see perfect restoration of these muscles without the early use of a binder; in fact, women who have employed it throughout the lying-in period do not secure an efficient abdominal wall more frequently than others who began its use two weeks after they were delivered. Even those physicians who advocate an early application of the binder concede that it works harm in certain cases and do not recommend it indiscriminately.

Those who postpone for a fortnight the use of the binder will escape the tendency it has to cause displacements. By this time the involution will have advanced so far that the womb lies within the pelvic cavity, where it is surrounded by the hip bones, which protect it from external forces that otherwise would influence its position. When permitted to get up patients ought to use a binder, because it counteracts the feeling of "falling to pieces" of which some complain when the abdominal walls are not comfortably supported. But there is no evidence to show that a binder plays any part in restoring the figure. When, in spite of ample rest, the abdominal muscles fail to recover completely, we have no better way of strengthening them than by use of calisthenics or massage.

The Pelvic Floor.—Second only in importance to having the womb restored to its original position is the necessity of restoration of the pelvic floor. This structure, also called the perineum, we should know, lies between the thighs, shuts in the bottom of the abdomen, and prevents prolapse of the viscera. In women it forms the lower portion of the birth-canal, enclosing the aperture through which the child enters the world. Although intelligent management of labor is of the greatest value for the protection of the pelvic floor, under certain circumstances it may be impossible to preserve it intact; injury to it is the rule when the first child is born, and not unusual in later births. There can be no doubt regarding the advisability of uniting the edges of a tear; indeed, to do so immediately is the very first essential toward restoring the pelvic floor to its wonted integrity. But even though tears are sewn up successfully, there is invariably some relaxation of the perineum until the restorative process, which here again chiefly concerns the muscles, has been given opportunity to become effective.

As with all the restorative changes in the lying-in period, to rest calmly in bed favors the perfect recovery of the pelvic floor more than anything else. Keeping the thighs together during the first few days undoubtedly assists tears in healing, but that precaution is not always necessary, and when it is the physician will call attention to the fact. The really important matter, as I have said, is that the upright position should not be resumed until the pelvic floor has become firm.
