Excessive menstrual bleeding in 12-year-old girls due to underdeveloped ovarian function is a normal physiological phenomenon. It is recommended to stay relaxed and not worry too much, get adequate rest during menstruation, avoid fatigue, ensure sufficient sleep, maintain a regular lifestyle, and refrain from strenuous exercise. Enhance nutrition by consuming more fresh vegetables and fruits rich in vitamins, and avoid spicy or irritating foods. Excessive menstrual bleeding in 12-year-old girls may result from hormonal instability or ovarian insufficiency, which is considered normal and can be managed through continued observation without immediate treatment.
