What factors cause irregular menstruation in girls?

Irregular menstruation is the most common phenomenon in the menstrual cycle and is also a type of gynecological disease. However, many people do not know much about the causes of irregular menstruation in girls . Let's explore the reasons.

1. The reason for irregular menstruation in women is related to dieting. Experts have shown that girls need fat to account for at least 17% of their body weight before menarche can occur. Body fat must reach at least 22% of body weight to maintain a normal menstrual cycle. Excessive dieting causes insufficient energy intake in the body, resulting in a large amount of fat and protein being consumed in the body, leading to estrogen synthesis disorders and obvious deficiency, resulting in irregular menstruation.

2. Smoking and drinking can easily cause menstrual irregularities. Certain components and alcohol in smoke can interfere with physiological processes related to menstruation, causing menstrual irregularities. Among women who smoke and drink excessively, 25%-32% of them go to the hospital for treatment due to menstrual irregularities and smoke more than one pack a day. Therefore, the cause of menstrual irregularities in girls is related to smoking and drinking.

3. The cause of menstrual disorders in girls is related to abnormal emotions. This is because menstruation is a hormone secreted by the ovaries. The hormones secreted by the ovaries after stimulating the endometrium are controlled by the hormones released by the pituitary gland and hypothalamus. Therefore, any abnormality in the function of the ovaries, pituitary gland, or hypothalamus will affect menstruation.

4. Cold stimulation causes irregular menstruation and even amenorrhea. According to research, cold stimulation during menstruation can cause excessive contraction of blood vessels in the pelvic cavity. Therefore, women should have a regular daily life and avoid overwork, especially during menstruation to avoid cold and dampness.
