menstruation

 [men″stroo-a´shun]
the periodic discharge from the vagina of blood and tissues from a nonpregnant uterus; the culmination of the menstrual cycle. Menstruation occurs every 28 days or so between puberty and menopause, except during pregnancy, and the flow lasts about 5 days, the times varying from woman to woman.
Menstrual Difficulties. Some menstrual discomfort is common, but acute discomfort is usually indicative of some disorder. Among the disorders sometimes causing dysmenorrhea are leiomyoma uteri, endometrial cysts, and displacement of the uterus. Menstrual pain may in some cases be related to tension or anxiety. Excessive bleeding or prolonged periods (hypermenorrhea) are sometimes an indication of tumors, polyps, cancer, or inflammation.

Menstruation usually starts between the ages of 11 and 14 and continues into the forties or fifties. At first the periods may be irregular, but once they are established they usually occur in a fairly definite rhythm, at intervals of 21 to 35 days. In these regular cycles, there may be monthly variations of a few days, which are considered normal. Cycle length may be influenced by changes in climate or living conditions, or by emotional factors. Slight irregularities, especially if they occur over a period of time, may be warnings of disturbance of either the thyroid or pituitary glands, or of tumors of the uterus or ovaries.

Occasionally menstruation does not occur at puberty; this is known as primary amenorrhea. It may be caused by underdevelopment or malformation of the reproductive organs, or by glandular disturbances, which generally can be corrected by the administration of hormones.

General ill health, a change in climate or living conditions, emotional shock, or, frequently, either the hope or fear of becoming pregnant can sometimes stop menstruation after it has begun (secondary amenorrhea). If this cessation is of short duration, it is not a cause for alarm. If it continues over a long period of time, and there is also the problem of infertility, hormone treatments may be necessary.
anovular menstruation (anovulatory menstruation) periodic uterine bleeding without preceding ovulation.
vicarious menstruation bleeding from extragenital mucous membrane at the time one would normally expect the menstrual period.

Patient discussion about menstruation

Q. preventing pre menstrual MIGRAINES. Has anyone come up with any good preventive medicine for migraines? Mine come systematically right before and during the menstrual cycle. My (male) neurolight in Paris didn't seem to see a linkk with migraines and my cycle - or offer any preventive advice. I take Relpax to relieve. Does anyone have a more natural or preventive solution?

A. I have the same problem and take Topomax to prevent the migrains. Also make sure you get enough rest right before you start. There seems to be a correlation. It took about 2 months to fully work but at least the first migrain after I started taking Topomax wasn't as severe.

Q. can you get poly-cystic ovarian syndrome when you still have your menstrual cycle?
