  1. Menstruation

    Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred. The first period, a point in time known as menarche, usually begins between the ages of 12 and 15. Menstruation starting as young as 8 years would still be considered normal. The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women. In adults, the range is between 21 and 31 days with the average being 28 days. Bleeding usually lasts around 2 to 7 days. Periods stop during pregnancy and typically do not resume during the initial months of breastfeeding. Menstruation, and with it the possibility of pregnancy, ceases after menopause, which usually occurs between 45 and 55 years of age. Up to 80% of women do not experience problems sufficient to disrupt daily functioning either during menstruation or in the days leading up to menstruation. Symptoms in advance of menstruation that do interfere with normal life are called premenstrual syndrome (PMS). Some 20 to 30% of women experience PMS, with 3 to 8% experiencing severe symptoms. These include acne, tender breasts, bloating, feeling tired, irritability, and mood changes. Other symptoms some women experience include painful periods and heavy bleeding during menstruation and abnormal bleeding at any time during the menstrual cycle. A lack of periods, known as amenorrhea, is when periods do not occur by age 15 or have not re-occurred in 90 days.


  1. menstruation

    Menstruation, also known as a menstrual period, is a natural biological process experienced by females which involves the shedding of the lining of the uterus (endometrium). This process usually occurs on a monthly basis, beginning at puberty and continuing until menopause, apart from when a woman is pregnant. It is part of the menstrual cycle, an intricate system regulated by hormones that prepares the female body for a possible pregnancy. Menstruation typically involves bleeding from the uterus, which is then discharged through the vagina.

Webster Dictionary

  1. Menstruationnoun

    the discharge of the menses; also, the state or the period of menstruating


  1. Menstruation

    Menstruation is the periodic discharge of blood and mucosal tissue from the uterus and vagina. It starts at menarche at or before sexual maturity, in females of certain mammalian species, and ceases at or near menopause. The periodicity of menstruation gives rise to commonly used euphemisms like "period" and "monthly". Women typically stop menstruating if they conceive or if they are breastfeeding. When menstruation stops for longer than about 90 days in the absence of pregnancy or breastfeeding, a medical evaluation should occur, as a number of health problems can result in absent menstruation. Menstruation lasts from puberty until menopause among non-pregnant women.

U.S. National Library of Medicine

    The vast majority of treatments for Crohn’s and ulcerative colitis are completely safe for a female to take when she is conceiving and equally safe during pregnancy and breastfeeding, for patients who are acutely ill, however, from their Crohn’s or ulcerative colitis, there may be multiple good reasons not to have children including depression, malnutrition, amenorrhea (lack of menstruation), and general poor quality of life.

    A specific underlying cause of irregular menstruation may increase the risk of premature death, rather than the irregular bleeding, per se.

It is important that women with PCOS speak to their doctor to reduce these risks.
