How much blood does a woman lose during her menstrual period

From the time a girl reaches puberty, shedding of the endometrium occurs once a month, which is called menstruation. Under normal circumstances, a woman's menstrual cycle begins to be irregular at the age of 12-14, and gradually becomes regular after 1-2 years. Menstruation gradually stops around the age of 45, and the period after menstruation is called menopause. According to survey statistics, the amount of blood loss during each menstrual period is about 75 ml. If a woman's menstrual period is calculated as 30 years, the total blood loss is about 27,000 ml (excluding childbirth bleeding), which is equivalent to the total blood volume in the bodies of 5.5 people weighing 60 kg.

Women have so much physiological bleeding in their lifetime

But it does not affect their physical health, and there is also a lot of data showing that the average life expectancy of women is higher than that of men.

Although the reasons here are complicated, from the perspective of blood physiology, we believe that it is related to the unique physiological characteristics of women. Because this kind of long-term, small amount of bleeding in women can stimulate the hematopoietic organs in the body to function more vigorously, it is not only beneficial to improve blood circulation in the body, but also comprehensively improves the activity function of various organs and tissue cells inside the body.

This unique physiological characteristic of women

It brings them health and longevity, or it can be said to be a special "gift" given by the "Creator" to the great mother of mankind.
