Profuse menstruation is also a relative term, as there is no definite standard as to amount of menstrual flow, nor the length of time it should continue. The profuseness must be measured by the condition of the individual. Where health seems fully maintained there would appear no cause for anxiety. But if there is a marked increase over the amount usual for the individual, if great weakness and prostration is produced, either at the time or afterward, it may be called profuse, and the cause may be either debility, that is weakness, or plethora, which means fullness. If from the latter, there will be throbbing headache, pain in the back, and general signs of fever. If from debility, there will be pallor, weakness, and perhaps an almost continuous flow. As may be imagined, the treatment in the two cases will differ. The full-blooded girl should be put on a plain, unstimulating diet, with plenty of out-door exercise during the month, but about twenty-four hours before the flow is expected she should have complete mental and physical rest. She should remain in bed, and apply cold wet cloths over the abdomen and between the thighs for an hour at a time, with intervals of at least one-half hour between the applications. The bowels should be freed from all fecal matter, and cool, small enemas be given two or three times a day. If these simple measures do not avail, the doctor should be consulted. The pale and debilitated girl needs to rest. Sometimes, if hemorrhage continues almost from one period to the next, she should remain in bed even after the flow seems checked. The great desideratum is to build up the general health, not by tonics, which are usually only stimulants, but by the judicious observance of the laws of health. This will, in many cases, call for the advice of the physician, who can see and study the patient and her special conditions. It is not safe to trust to book-doctoring. CHAPTER XVIII. CARE DURING MENSTRUATION. I have said that I do not want you to think yourself a semi-invalid and so be "fussy" about yourself, but I have also said that I want you to take care of yourself at all times, and especially during your menstrual periods. How can you make these ideas agree with each other? I know that many writers say that a girl should spend one day each month in bed, or at least lying down; that there are some things that should always be forbidden to girls, simply because they are girls, such as running up and down stairs. These wholesale restrictions make girls rebellious at their womanhood. I simply want you to use good sense at all times in your care of yourself.
