What is the reason for a girl's period to come early?

The normal menstrual cycle of women is about 28 days. If the menarche cycle is consistently advanced by more than 7 days, or even if menstruation occurs twice in a month, it is called "early menstruation", also known as "early menstruation" or "early menstruation". The doctor reminds that if it is only 3 to 5 days earlier and there are no other obvious symptoms, it is within the normal range. Sometimes, an early period does not count as an early menstrual period, so there is no need to be too anxious. There are many reasons for early menstruation, the main ones include the following categories.

1. Caused by organic diseases or drugs: including inflammation, tumors, growth and development abnormalities, malnutrition of the reproductive organs; brain diseases; other endocrine imbalances such as thyroid cysts, etc.

2. Caused by endocrine imbalance: mainly due to unstable or defective function of the hypothalamic-pituitary-uterine-ovarian axis, that is, menstrual disorders.

3. Qi deficiency: People with irregular diet or excessive fatigue are prone to damage their temperament. The spleen is the "manager" of blood. If the "manager" is weak, the "managed" will inevitably "make trouble" and cause early menstruation. As the Jingyue Complete Book of Women's Regulations states: "If there is no fire in the pulse and the menstruation is early but not on time, it is because the heart and spleen qi are weak and cannot be restrained."

4. Heat in the blood: People with excessive qi and blood, or who take too much irritating food and tonics, or who are depressed, or who have lost too much blood due to long-term illness, are very likely to have heat in the blood. When the blood gets hot, it flows inefficiently and the water flow also speeds up, causing menstruation to come early. "Dan Xi's Heart Method" says: "If the menstrual period does not come as expected, it is due to blood heat." Blood heat can be divided into real heat, false fire, and liver qi stagnation that damages body fluid.

5. Pregnancy status: Early menstruation is also related to pregnancy status. The older you are when you get pregnant, the sooner you will reach menopause, and the less frequent your pregnancies, the sooner you will reach menopause. This is because the older the age of the first pregnancy, the lower the frequency of pregnancy, which causes the frequency of ovulation in girls to increase and menopause to come faster. In addition, the longer the breastfeeding period, the later the menopause. This is because the ovulation period will be affected during breastfeeding. If the breastfeeding period increases, the frequency of ovulation will decrease.
