periodën

Periodën, also known as menstruation, is a natural biological process that occurs in individuals with a uterus as part of their reproductive cycle. It involves the shedding of the uterine lining, known as the endometrium, along with blood and mucus, which is then expelled from the body through the vagina. This typically happens monthly and is regulated by hormones, primarily estrogen and progesterone.

The menstrual cycle generally begins at puberty, around the age of 10-16, and continues until menopause, which usually occurs between the ages of 45 and 55. The duration of a period can vary, but it commonly lasts between 3 to 7 days. The amount of blood loss is also variable, typically ranging from 30 to 80 milliliters per cycle.

Menstruation is a sign of reproductive capability and is a healthy, normal bodily function. While it is a natural process, some individuals experience symptoms such as cramps, bloating, mood swings, and fatigue, collectively known as premenstrual syndrome (PMS). These symptoms can range from mild to severe and can be managed through various methods including lifestyle changes, medication, and therapies. The regularity and characteristics of menstrual cycles can also provide insights into a person's overall health.
