Disorders of menstruation (which include absent periods, infrequent periods, irregular periods, or heavy periods) may be due either to abnormalities of hormone secretion or physical abnormalities of the uterus and ovaries.

Accordingly, the diagnosis of these conditions involves hormone determinations (usually in blood) as well as physical examination and imaging of the reproductive organs with ultrasound and/or x-ray. Treatment of menstrual disorders depends on the condition and the needs of the patient. Example treatments include hormone medication, herbs, surgery and no intervention.
