Normal menstruation frequency, duration, and amount?
Fequency: 24-35 days.
Duration: 4 -7 days.
Amount: 30mls (whatever that means)
Is all uterine bleeding menstruation?
Nope. Can be just withdrawal bleeding, anovulatory bleeding, other bleeding - but patients will call all of it a period.
What’s the first dichotomy in the DDx for abnormal bleeding?
Structural vs. hormonal.
If bleeding follows a regular cycle but is too heavy, does that point toward a structural or hormonal problem?
More likely structural. (most common reason would be fibroids)
If a post-menopausal female has vaginal bleeding…
Look for cancer, but benign conditions (polyps, etc.) are most common.
