What is the average duration of menstrual flow?
4 days
What is menorrhagia?
Heavy bleeding that occurs at regular intervals (>7 days or > 80 ml). AKA hypermennorrhea.
What is metrorrhagia?
Bleeding occurring at irregular but frequent intervals.
What is menometrorrhagia?
Prolonged bleeding occurring at irregular intervals.
What is dysmennorrhea?
Painful uterine bleeding.
What should we use to clinically assess the loss of blood during menses?
Do NOT use pad/tampon count b/c they're unreliable. Questions concerning passage of blood clots and degree of inconvenience are more helpful.
How is hypothyroidism related to menstrual abnormalities?
It is often assoc w/ menometrorrhagia.
How is hyperthyroidsm related to menstrual abnormalities?
It is often assoc w/ oligomenorrhea and amenorrhea.
What is dysfunctional uterine bleeding (DUB)?
It is excessive bleeding w/ no demonstrable organic cause; it is almost always due to endocrinologic abnormality.
In dysfunctional uterine bleeding, 85% of patients are anovulatory secondary to what? What does this result in?
Secondary to alterations of neuroendocrine function. This results in continuous unopposed estrogen production, and the endometrium continues to proliferate, which eventually sloughs as it outgrows its blood supply.
What are the two treatments for acute bleeding/hemorrhage of the internal uterus?
Estrogen and Progestin
How does estrogen therapy help w/ acute bleeding/hemorrhage of the internal uterus?
In pharmacologic doses, estrogen causes rapid growth of the endometrium and covers denuded areas. After bleeding stops, combine w/ progestin for 7-10 days and expect synchronized bleeding that may be heavy.
How is progestin used to treat acute bleeding/hemorrhage of the internal uterus?
It is used for anovulatory bleeding. It prvents endomentrial neoplasia that may result from unopposed estrogen.
How do NSAIDs help with uterine bleeding?
They block COX which causes:
1. Dec PGI2 = vessel wall relaxation and dec platelet aggregation.
2. Dec Thromboxane = vessel wall constriction, inc platelet aggregation
3. Dec menstrual blood loss and improved dysmenorrhea.
