During pregnancy the mother must get rid not only of her own waste products, but also of those of the child. The waste products of the child, if weighed, would not amount to a great deal; but they are by no means negligible. So far as we can tell, it is chiefly on account of their peculiar character that they increase the work of the mother's excretory organs. Whatever the cause, they do increase it, and experience has taught us that these organs must always be kept in a healthful condition to protect both the mother and the child from harm. Consequently a prospective mother who wishes to take proper care of her body must, in the first place, direct her attention toward keeping up the normal activity of all the excretory functions. THE BOWELS.--While pregnant, nine out of ten women suffer from mild constipation. Those who have been previously troubled with this complaint may find it aggravated from the outset, but in most instances it does not appear until after several months have passed. Constipation is explained by the fact that the enlarged womb presses against the intestines; and, as the enlargement increases, constipation generally becomes more pronounced. No doubt there was a time when women, perhaps unconsciously, counteracted this natural result of pregnancy by the use of a diet consisting largely of fruit and vegetables and also by outdoor exercise. Such measures, indeed, still afford the simplest means of overcoming constipation. Throughout pregnancy the bowels should move at least once every day. When they do not, some of the waste material that should be removed is absorbed by the body and seeks to leave it through the organs that are already doing their full share of work. For example, under such conditions, the kidneys, instead of exerting themselves more vigorously, may become less active than they were. It is everyone's duty to form the habit of having the bowels move regularly. Now the most favorable opportunity for assisting the intestines to empty themselves occurs shortly after meal-time, since the involuntary movements of the intestines are most active while digestion is in progress. It should be regarded as an imperative duty, therefore, to grant Nature such an opportunity every morning just after breakfast. This should be done at a definite hour, day after day, even though the inclination is absent; and in many instances the desired habit will be formed.
