In the case I mentioned, where the reproductive organs were lacking, the girl had been subjected to a long course of home medication which had proven disastrous to her digestion, and yet, as will be readily understood, had not resulted in the establishment of a function that is dependent upon organs which, in this case, did not exist. Sometimes there are slight mechanical hindrances which can only be determined by the physician, though their presence will be indicated by the symptoms of menstruation without the accompanying sanguineous discharge. In these cases the home medication is dangerous. If the girl regularly has symptoms of approaching menstruation, with pain and bloating, and these subside without flow, it would be wise to consult the physician instead of resorting to domestic remedies or letting the matter go on without attention. Quite frequently the first appearance of menstruation is followed by weeks or even months of freedom from its reappearance. In these cases no alarm need be felt as long as the general health is not affected. Again, there may be suspension of the function from change of surroundings. Girls who go away to school often suffer from irregularity. I have known of a case where the girl never menstruated during the school year, but was perfectly regular during vacations. These cases may be accounted for by the nervous strain, the using up of vital forces in mental effort to such degree that there is nothing left with which to carry on the menstrual function. In all such cases it is wise to watch carefully the general health, and if all functions are not properly conducted, to reduce the strain until the vitality is able to keep all functions in order. Girls are sometimes disturbed because the flow is scanty, and think they should do something to increase the amount. It is no doubt true that profuse menstrual flow is the result of our artificial lives. If we lived more normally we should have naturally a scanty menstrual flow. Therefore if a girl has good health and no monthly pain and the flow is scanty, she may consider herself as more nearly in a normal state, and be thankful. If, however, the menses are suddenly less than normal it denotes a suppression, which may be the result of cold, exhaustion of body, weariness of nerves, mental anxiety, or disturbance of the emotions. If gradual suppression occurs, accompanied by loss of health, it indicates some constitutional difficulty or local trouble which demands professional counsel.
