What are light periods?
Light periods are menstrual periods that have an unusually light flow or a very short duration of blood loss. Although the menstrual cycle varies from person to person, most women have a normal period approximately every 28 days. Each period typically lasts from four to seven days. The amount of blood lost during a menstrual period ranges from 20 to 80 milliliters (mL). Blood loss of less than 20 mL may be considered a light period.
A shift or imbalance in hormone levels is the main cause of light periods. Light periods most commonly affect women who are approaching menopause because at that time in their lives women produce less estrogen, one of the hormones that regulates menstrual periods. Light periods can also occur in girls who have just begun to menstruate. An eating disorder, excessive exercise, or a thyroid condition can also cause a woman to have light periods. Women who use hormonal contraceptives, including oral contraceptives, may also experience lighter periods.
