The cause of amenorrhea in 15-year-old girls may be related to hormone imbalance, malnutrition or psychological stress. Treatment methods include adjusting diet, psychological counseling and drug intervention when necessary. Hormone imbalance is a common cause. Polycystic ovary syndrome or thyroid dysfunction may cause menstrual cycle disorders. Malnutrition, such as low weight or lack of vitamins and minerals, can affect hormone secretion and lead to amenorrhea. Excessive psychological stress or anxiety may also interfere with the function of the hypothalamus-pituitary-ovarian axis and affect the normal menstruation.

1. Hormone imbalance: diseases such as polycystic ovary syndrome, thyroid dysfunction or pituitary tumors may cause amenorrhea. It is recommended to see a doctor to check hormone levels. After the diagnosis is confirmed, oral contraceptives, thyroid hormone replacement therapy or surgical treatment can be used according to the doctor's advice.

2. Malnutrition: Being underweight, having an unbalanced diet, or lacking nutrients such as iron and vitamin D can affect the menstrual cycle. It is recommended to increase the intake of foods rich in protein, iron, and vitamins, such as lean meat, fish, green leafy vegetables, and nuts, and supplement vitamins and minerals when necessary.

3. Psychological stress: Study pressure, family conflicts or emotional problems may interfere with hormone secretion. It is recommended to relieve stress through psychological counseling, relaxation training or meditation, and use anti-anxiety drugs under the guidance of a doctor if necessary.

4. Other causes: Strenuous exercise, chronic diseases or abnormal development of the reproductive system may also cause amenorrhea. It is recommended to reduce high-intensity exercise, treat the primary disease, and perform a reproductive system examination if necessary.

There are many reasons for amenorrhea in 15-year-old girls, and targeted treatment is required according to the specific situation. Early detection and intervention can help restore the menstrual cycle and avoid long-term health problems.
