Menstruating

Menstruation, also known as a period or monthly, is the regular discharge of blood and mucosal tissue (known as menses) from the inner lining of the uterus through the vagina. The first period usually begins between twelve and fifteen years of age, a point in time known as menarche. They may occasionally start as early as eight, and this onset may still be normal. The average age of the first period is generally later in the developing world and earlier in 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 and 21 to 31 days in adults (an average of 28 days). Bleeding usually lasts around 2 to 7 days. Menstruation stops occurring after menopause which usually occurs between 45 and 55 years of age. Periods also stop during pregnancy and typically do not resume during the initial months of breastfeeding.

Causes

Menstruation is a natural part of the reproductive cycle in which blood from the uterus exits the body through the vagina. It occurs as part of a woman's monthly cycle, typically every 28 days, but can vary from woman to woman and month to month. This cycle is an indication that a woman is not pregnant.

Symptoms

Common symptoms of menstruation include abdominal cramping, bloating, mood swings, and general fatigue. Some women may also experience nausea, vomiting, or diarrhea.

Treatment

While menstruation is a natural process, some women may experience discomfort or pain. Treatment options can include over-the-counter pain relievers, hormonal birth control, and lifestyle changes such as regular exercise and a healthy diet.
