What are the reasons for menstruation to come four days early?

The period from the first day of menarche to the first day of the next menstrual period is called the cycle time. The standard cycle is 28-30 days, and it is normal to be earlier or later than 1 week. So, what is the reason for early menstruation? Early menstruation in women is closely related to symptoms, endocrine environment, therapeutic drugs, diet, mentality and other factors. The reasons for women's early menstruation include:

1. Symptom elements. If a woman suffers from certain diseases, including inflammation of the reproductive organs, tumors, brain diseases, endocrine imbalance, or takes medication for a long time, it is very easy to cause irregular menstruation in women.

2. Endocrine imbalance. The main reason is that the hypothalamus-pituitary-pituitary-uterine-ovarian axis is unstable or defective, which can easily lead to unstable menstruation in women.

3. Influence of therapeutic drugs. Some therapeutic drugs can cause endocrine disorders in women after taking them, such as some emergency contraceptives, radiotherapy and chemotherapy drugs, and drugs for treating mental illnesses. After stopping this treatment, menstrual periods usually return slowly.

4. The impact of the contraceptive ring. Some women may experience early menstruation after having an IUD inserted. There is no need to worry too much about this situation, as the menstrual period will gradually return to normal.

5. Diet combination. If women consume excessive or long-term stimulating foods and supplements, or if they are malnourished due to dieting, it is easy to cause changes in the endocrine environment and cause irregular menstruation.

6. Changes in living environment. Changes in the external environment, such as changes in living environment, job transfer, etc., can disrupt the menstrual cycle of some women.

7. Attitude. Fluctuations in women's mentality, such as extreme joy or sorrow, depression, and too much pressure from food, clothing, housing, transportation, and work can all affect their endocrine system and cause early menstruation.
