Causes of irregular menstruation in young girls

What causes irregular menstruation in young girls?

2. Menstrual irregularities in young girls are caused by poor ovarian function. Menstruation is cyclical bleeding caused by changes in endometrial ovarian hormones. Ovarian ovulation occurs regularly every month, depending on the normal functioning of the gonadal axis composed of the ovaries, pituitary gland, and thalamus. Problems with the endometrium and gonadal axis can lead to menstrual irregularities.

3. It may also be due to external factors, climate change, mental factors, regional differences after transferring schools, tension or illness before exams, which are also the reasons for irregular menstruation in girls. Changes in living environment, mood swings, increased life pressure, strenuous exercise, weight gain or loss, or taking certain medications may affect menstruation. Especially the problem of greed for coolness, some women do not pay attention to keeping warm during menstruation, such as often eating some frozen foods such as ice cream, ice cream, and various frozen drinks. Some women even wear very thin clothes in winter to look beautiful. In fact, these behaviors can lead to pelvic vasoconstriction, ovarian dysfunction, oligomenorrhea, and even amenorrhea.
