Q:

What causes a short menstruation period?

A:

According to Everyday Health, a short menstruation period may be caused by low estrogen levels, early pregnancy, menopause, birth control, thyroid disorder, polycystic ovary syndrome, weight loss, excessive exercising, eating disorders and stress. The length of normal menstruation periods vary between women. The most important determining factor is whether or not a woman is experiencing her period regularly.

Everyday Health explains that a woman's menstrual cycle lasts between 21 to 35 days. This cycle may fluctuate by a couple of days each month. Some women menstruate for only three days, and others menstruate for as many as seven. As long as a woman experiences the same average menstruation period every month without skipping a period, she most likely does not need to worry about her cycle.

In some cases, certain forms of birth control cause a woman to experience fewer menstruation cycles. If missed periods are not caused by expected birth control influences, Everyday Health recommends that a woman should visit her doctor or gynecologist to assess possible health complications. The most common cause of intermittent menstruation is an underlying hormonal imbalance. A doctor is able to order blood work and perform a physical exam to rule out any matters of concern.
