It is not normal to have a period that lasts for only one day, but it may not signal a serious problem as long as a woman consistently bleeds for just one day each month, according to Everyday Health. It is best to meet with a doctor to be sure.
Every woman's cycle varies in length and regularity and is controlled by a complex system of hormones, explains Everyday Health. The normal range for bleeding is between three and seven days, but healthy women can bleed slightly outside of that range without health complications. Sometimes short periods may signal an underlying health condition, such as hormonal imbalances, bulimia, anorexia, extreme exercising, chronic stress, ectopic pregnancy, thyroid disorders and polycystic ovarian syndrome. Young girls and menopausal women are likely to experience menstrual irregularities as their bodies go through hormonal fluctuations. These symptoms often subside when hormones such as estrogen and progesterone relax into a new balance.
Some methods of birth control are designed specifically to alter a woman's hormonal landscape so that she experiences less-frequent and lighter periods, notes Everyday Health. Short periods are not alarming unless one suddenly occurs or a woman skips her period for 60 days with only light spotting. In these cases, it is important to see a doctor to discuss symptoms and rule out health problems.
