"monthly discharge of blood from the uterus," 1590s, from Latin menses, plural of mensis "month" (see moon (n.)).
Usage examples of "menses".
Non-appearance, as well as suppression of the menses, may result from an abnormal state of the blood.
When impregnation occurs immediately before the appearance of the menses, their duration is generally shortened, but not sufficiently to establish the suspicion that conception has taken place.
The symptoms which indicate pregnancy are cessation of the menses, enlargement of the mammae, nausea, especially in the morning, distention of the abdomen, and movement of the foetus.
A second menstrual failure strengthens this suspicion, although there are many other causes which might prevent the appearance of the menses, such as disease of the uterus, general debility, or taking cold, and all of these should be taken into account.
In the absence of all apparent influences calculated to obstruct the menses, the presumption ordinarily is that pregnancy is the cause of their non-appearance.
A very reasonable way to compute the term, is to reckon three months back from the day when the menses ceased and then add five days to that time, which will be the date of the expected time of confinement.
Preceding the first appearance of the menses, girls usually feel an aching in the back, pains in the limbs, chilliness, and general languor.
Motherwort is usually given in warm infusion, in suppression of the menses from cold.
Acute suppression of the menses from a cold, may be relieved by the tincture of aconite in drop doses every hour.
Menstruation, or the menses, monthly visitation, catamenia, menstrual flow, courses, or periods, usually makes its appearance in the female between the twelfth and fifteenth years, at which time the reproductive system undergoes remarkable changes.
Retention of the menses may result from malformation of the vaginal canal, which sometimes terminates before it reaches the womb, being simply a short, closed sac.
In robust, plethoric females the menses are sometimes very tardy in their appearance, and every month the attempt to establish this function is attended with pain in the head, loins, and back, chilliness, nausea, and bloating of the abdomen.
As acute suppression of the menses is due to derangement of the circulation of the blood, caused by taking cold, by violent excitement of the propensities or excessively strong emotional experience, the prominent indication is to secure its speedy equalization.
Upon the return of the menses, there is a dull, heavy, fixed pain in the pelvis, which continues until the period is completed.
The tissues are destroyed, and, as the parts heal, the deeper-seated tissues firmly contract, forming a hard, unyielding cicatrix, thus constricting the neck of the womb, through which the menses pass into the vagina.
