kuukautisvuotoon

Kuukautisvuotoon, also known as menstrual bleeding or menstruation, is a natural physiological process that occurs in many women and individuals with uterine ovaries. It marks the cyclical shedding of the uterine lining (endometrium) when pregnancy does not occur after ovulation. This process typically takes place on a regular basis, often every 21 to 35 days, and can last from 2 to 7 days.

Menstrual bleeding involves the discharge of blood, tissue, and other endometrial materials through the vagina. It is regulated by hormonal fluctuations, primarily involving estrogen and progesterone, which influence the growth and breakdown of the uterine lining. The cycle begins with the follicular phase, during which follicle-stimulating hormone (FSH) stimulates ovarian follicles; followed by ovulation, when a mature egg is released. If fertilization does not happen, hormone levels decline, leading to the shedding of the endometrial lining.

The characteristics of menstrual flow can vary widely among individuals, ranging in color from bright red to dark brown, and in volume from light to heavy. Common symptoms accompanying menstruation may include abdominal cramps, breast tenderness, mood swings, and fatigue.

Menstrual hygiene is important for health and well-being. Women typically use sanitary pads, tampons, menstrual cups, or other absorbent materials during their periods. Maintaining good hygiene, managing symptoms, and understanding the menstrual cycle are vital aspects of reproductive health.

Menstrual cycles are a key indicator of female reproductive function. Deviations from typical patterns, such as irregular cycles, heavy bleeding, or absence of menstruation, may warrant medical consultation to diagnose underlying health issues.
