What are the causes of irregular menstruation in girls?

One of the main characteristics of changing from a girl to a woman is menstruation. However, with the arrival of menstruation, some girls will have irregular menstruation. So what are the causes of irregular menstruation in girls? The following describes the causes of irregular menstruation in girls:

Reason 1: During adolescence, the neuroendocrine regulation function of the hypothalamus-pituitary-ovarian axis is not fully mature, resulting in irregular menstruation. Although the follicles in the ovaries are mature, they do not ovulate. It is not until the ovaries are fully developed and function properly that the eggs can mature and be released once a month, and menstruation will come on time every month. This is one of the reasons for irregular menstruation in girls.

Reason 2: There are individual differences in the cyclical response of the endometrium to sex hormones. The physiological and psychological state of adolescence will affect the release of sex hormones and change the normal menstrual cycle rhythm.

Reason 3: The big changes in life and work of adolescent women can also cause irregular menstruation in girls. Generally speaking, environmental changes, excessive exercise, mood swings, or changes in life such as exams, relocation, and nutrition can affect the length of the menstrual cycle and the amount of menstrual blood discharged.

The above are the reasons for irregular menstruation in girls. Experts suggest that irregular menstruation in girls will cause inconvenience in life, work, study and other aspects, so please choose a regular hospital for treatment in time.
