What causes less menstrual flow?

Normal menarche is a symptom that every healthy woman has, but women with irregular daily lives may suddenly experience a decrease in menstrual flow. Usually, this symptom does not attract their attention at the beginning, so they will allow the symptom to develop and eventually may cause a series of health hazards. Let’s take a closer look at what causes less menstrual flow. It is still important to deal with problems immediately.

Some women have very little menstrual flow from the beginning of their first menstruation, which may be caused by uterine hypoplasia. A sudden decrease in normal menstrual flow may be caused by abnormal hormone secretion or anovulatory menstruation.

The main reasons for low menstrual flow include the following three aspects

1. Uterine hypoplasia. Menstruation is the shedding and bleeding of the uterine wall that occurs with the change of the uterine and ovarian cycle. If the uterus is underdeveloped, such as the uterus is enlarged or deformed, only a small amount of uterine wall will fall off in each menstrual cycle, resulting in a small amount of menstrual flow. In addition, endometrial tuberculosis causing endometrial degeneration or curettage causing damage to the uterine wall can also lead to scanty menstruation or even amenorrhea.

2. Abnormal growth hormone metabolism. Estrogen can stimulate the proliferation of women's uterine wall. If the body's hormone secretion is abnormal, the proliferation of the uterine wall will not reach the required thickness, resulting in less menstrual flow. Excessive dieting, excessive work and rest time, bad mood, urinary system diseases, etc. will affect the female endocrine environment, causing abnormal hormone secretion and small menstrual flow.

3. Anovulatory menstruation. Women who do not ovulate will still have their periods, which is medically called "anovulatory menstruation." This is different from normal menstruation and falls into the category of "multifunctional abnormal uterine bleeding". The characteristics of this type of menstruation are irregular time and very little blood.

Can anemia cause low menstrual flow?

Small menstrual flow means that a woman has too little blood during her period, or her menarche is too short. Menstrual volume refers to the total amount of blood loss during a menstrual period. Normal menstrual volume is 20-80mL. If it is lower than this standard, it is considered too little menstrual volume. Some women have very little menstrual flow from the beginning of their first menstruation, which may be caused by uterine hypoplasia. If the menstrual flow, which has always been normal, suddenly decreases, it may be caused by abnormal male hormones or anovulatory menstruation.

"Anemia" refers to a common clinical manifestation in which the volume of blood cells in the body's peripheral blood is reduced, which is significantly below the lower limit of the normal range. The main cause of anemia is malnutrition, which leads to a series of immune and nervous disorders and hematopoietic dysfunction. The amount of menstrual blood is not exactly the same for each person, and even for the same person the amount of menstrual blood is not exactly the same each time. If the menstrual cycle is normal, the amount of menstrual blood is less than 10ml or so little that even the double-layer paper cannot be wet, even if the amount of menstrual blood is small. During menstruation, you should keep warm, avoid cold, raw, and cold irritants, and avoid being eroded by dampness. Pay attention to rest, reduce fatigue, improve nutrition and enhance resistance. You should try your best to control strong mood fluctuations, avoid obvious mental stimulation, and maintain a good mood. In normal times, you should avoid excessive sexual intercourse, and sexual intercourse is strictly prohibited during the menstrual period.
