For women, menstruation that occurs at least 3 days early are relatively common: in some cases, the episode is entirely occasional and has no clinical significance; at other times, the shortening of the menstrual periods may indicate the presence of a disorder of the menstrual cycle.
If recurrent or associated with other symptoms, early menstruation deserves medical attention. To ascertain the reasons for this phenomenon, usually, the measurement of hormone levels in the blood and the "execution of a" pelvic ultrasound is required.
Possible causes of early menstruation include some endocrine dysfunctions, pathologies of the uterus and ovaries, massive drug intake and systemic diseases that can debilitate the body and cause an imbalance. If necessary, treatment of menstruation early is aimed at the triggers.
