What are the causes of irregular menstruation in women?

Qiandan: What are the causes of irregular menstruation in women? As people's lifestyles gradually improve, more and more women are suffering from irregular menstruation. So what are the causes of irregular menstruation in women? In response to this question, we would like to ask experts to give us a detailed introduction to the causes of irregular menstruation in women, hoping to help you.

Causes of irregular menstruation in women:

First, excessive dieting. Experts have shown that girls need to have at least 17% body fat to have their first menstruation, and body fat should be at least 22% body fat to maintain a normal menstrual cycle. Excessive dieting, due to insufficient energy intake, causes a large amount of fat and protein to be consumed, resulting in estrogen synthesis disorders and obvious deficiency, affecting menstruation, and even causing scanty menstruation or amenorrhea. Therefore, women who pursue a slim figure must not diet blindly, as this is the cause of irregular menstruation in women.

Second, artificial abortion can cause irregular menstruation. After artificial abortion, the ovaries can generally resume ovulation within 22 days, and menstruation will come in about 1 month. However, a small number of women experience menstrual disorders such as prolonged menstruation, irregular cycles, and amenorrhea after artificial abortion. This situation generally returns to normal after 2-3 months, and a few people last longer, which is also one of the reasons for women's irregular menstruation.

Third, endocrine disorders: This is the most common cause of menstrual disorders, especially in adolescent girls and menopausal women. Endocrine disorders cause anovulatory bleeding, which results in irregular menstruation during the first menstruation or near menopause. In addition, it causes the unlimited growth of the endometrium, which grows to a thickness that the uterus itself cannot bear, causing breakthrough bleeding. Therefore, the amount of menstrual blood is often small and dark brown in the early stage, and will develop into heavy bleeding over time.

Fourth, abnormal emotions. Long-term mental depression, sulking, or major mental stimulation and psychological trauma are obvious causes of irregular menstruation in women. They can all lead to menstrual disorders or dysmenorrhea and amenorrhea. This is because menstruation is formed after the hormones secreted by the ovaries stimulate the endometrium, and the hormones secreted by the ovaries are controlled by the hormones released by the pituitary gland and hypothalamus. Therefore, whether the functions of the ovaries, pituitary gland, or hypothalamus are abnormal, it will affect menstruation.

4. Caused by organic diseases or drugs: including local inflammation, tumors and developmental abnormalities of reproductive organs, malnutrition; intracranial diseases; other endocrine dysfunctions such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease, etc.; liver diseases; blood diseases, etc. People who use drugs to treat mental illnesses; endocrine preparations or intrauterine contraceptive devices may experience irregular menstruation. Some professions such as long-distance runners are prone to amenorrhea. In addition, some abnormal bleeding during pregnancy is often mistaken for irregular menstruation, which is also the cause of irregular menstruation in women.
