menstruasjonsvæske

Menstruasjonsvæske, commonly referred to as menstrual fluid or menstrual blood, is the discharge from the uterus that occurs during menstruation. It is composed of blood, uterine lining (endometrium), mucus, and vaginal secretions. The color of menstrual fluid can vary from bright red to dark brown or even black, depending on the flow rate and how long the blood has been exposed to air.

The composition and appearance of menstrual fluid are normal physiological occurrences for individuals with a uterus who are of reproductive age. The shedding of the uterine lining is a natural part of the menstrual cycle when pregnancy does not occur. The fluid typically exits the body through the vagina.

The volume of menstrual fluid can differ significantly from person to person and from cycle to cycle. The average blood loss during a menstrual period is about 30 to 60 milliliters, though some may experience less and others more. Factors such as age, hormonal balance, and underlying health conditions can influence the volume and consistency.

While menstrual fluid is primarily blood, it often appears darker than peripheral blood because it has a lower concentration of oxygen. The presence of mucus helps to lubricate and carry the fluid out of the body. Understanding the normal characteristics of menstrual fluid is important for recognizing potential health concerns, though variations within a typical range are common.
