_A woman in perfect health_ need take no especial care and make no change in her manner of life at this period. But under our artificial habits of life, such a woman is the exception rather than the rule, and in most cases some attention must be paid to the recurrence of the menses. Many young ladies in attendance upon school, feel a need of some indulgence at that time, and are often granted respite from duty. Women following any regular occupation have learned to plan a day of lighter work at the recurrence of the period. Yet on the contrary some have found that congestion and pain are relieved by occupation sufficient to interest the mind, with exercise adapted to increase the circulation. THE DISORDERS incident to menstruation are: Amenorrhea, Dysmenorrhea and Menorrhagia. _Amenorrhea_ is absence or suppression of the menses caused by cold, a chronic ailment, an anemic condition or some ovarian or uterine affection. It is also often the result of mental conditions, as grief, fright or severe mental strain. One need not be uneasy about suppression when there is no special constitutional disturbance. Our grandmothers taught that the absence of the menses was always greatly to be feared, the prevailing idea being that serious results would follow to some vital organ. This is a mistake. Patients during treatment for uterine ulceration and inflammation often gain steadily in health, although the menses cease for months. This has been observed especially in hygienic institutions. At all events, in treating suppression avoid strong remedies, such as old-fashioned tansy tea, steel filings and ergot. These produce congestion, and may be the source of severe chronic ailments. See to it that a general condition of health is attained. With plenty of out-door exercise, congenial employment and freedom from care, the young girl may, with rare exceptions, trust to nature for correction of suppression. _Dysmenorrhea_, or painful menstruation, is of such frequent occurrence that it deserves especial attention. Most young ladies experience more or less suffering at this time. It may be only nervousness, wakeful nights, a slight headache, some pain in the back or pelvic regions, and a disposition to be alone; or the attacks may be severe, with pain in the back and pelvis, running down into the limbs; the surface and extremities cold, face pallid, with nausea, vomiting or fainting, and perhaps spasms. This ought not to be, and, in most instances, need not be. With our present knowledge, the conditions for and causes of dysmenorrhea may be removed. Among causes we find inflammation of the ovaries, oviducts, or mucous membrane of the womb, mechanical closure of the outlet of the womb, or, simply constipation, neuralgia or rheumatism.
