Many women are very concerned about their menstrual flow. They don't care if their flow is heavy, but they worry if their flow is light. In fact, heavy menstrual flow can easily lead to anemia and affect health, while relatively light menstrual flow does not require special treatment unless there are other underlying medical conditions.
According to the definition in the 8th edition of the Obstetrics and Gynecology textbook, menstruation refers to the periodic shedding and bleeding of the uterine lining that accompanies the cyclical ovulation of the ovaries.
Normal menstrual cycle:
(1) Normal menstruation is cyclical.
(2) Menstrual cycle: The interval between the first day of two menstrual periods is called a menstrual cycle. It is generally 21-35 days, with an average of 28 days.
(3) Menstrual period: The duration of each menstrual period is called the menstrual period, which is generally 2-8 days, with an average of 4-6 days.
(4) Menstrual flow: Menstrual flow is the total blood loss during one menstrual period. Normal menstrual flow is 20-60ml.
Characteristics of menstrual blood:
Menstrual blood is dark red and consists mostly of blood (75% from arteries and 25% from veins), along with fragments of the uterine lining, cervical mucus, and shed vaginal epithelial cells. Menstrual blood does not clot; clots only form in cases of heavy bleeding.
Menstruation is the periodic shedding and bleeding of the uterine lining, primarily composed of blood. Many women mistakenly believe that light menstrual flow indicates an accumulation of toxins, similar to urination or defecation, which is completely incorrect. Menstrual flow less than 20ml is considered light menstrual flow. The main causes are damage to the uterine lining and declining ovarian function. If an underlying medical condition is found, treatment should target the cause. If no organic lesions are found, functional issues are not a major concern. Once diseases affecting menstruation are ruled out, observation is sufficient. Slightly less menstrual flow compared to previous periods will not cause any harm to the body.
Menstrual flow exceeding 80ml is considered heavy menstrual flow.
There are many reasons for heavy menstrual bleeding, and it can easily lead to anemia. The cause should be identified first, and then medical treatment should be sought as soon as possible, depending on factors such as age and fertility requirements.
