What should I do if a student hasn't had her period for several months?
Generally, if a female student hasn't had her period for several months, it may be due to excessive academic stress, extreme dieting for weight loss, polycystic ovary syndrome (PCOS), hyperprolactinemia, or endometrial adhesions. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through lifestyle adjustments, medication, or surgical treatment as appropriate. Specific causes are analyzed as follows:

1. Excessive academic stress: Prolonged mental tension can disrupt endocrine function and lead to dysfunction of the hypothalamic-pituitary-ovarian axis, thereby affecting the menstrual cycle. Maintain regular sleep patterns and avoid staying up late. Engage in 30 minutes of moderate exercise such as jogging or yoga daily to relieve stress. Communicate regularly with family and friends to express emotions and maintain emotional stability.
2. Extreme dieting for weight loss: Deliberately restricting food intake leads to inadequate nutrition and insufficient raw materials for estrogen synthesis, resulting in amenorrhea. Restore a balanced diet, ensure adequate protein and vitamin intake, and consume more lean meat, eggs, soy products, and fresh fruits and vegetables. Avoid blind or extreme dieting.
3. Polycystic ovary syndrome (PCOS): Hormonal and metabolic abnormalities cause ovulation disorders, manifesting as infrequent menstruation or amenorrhea, often accompanied by hirsutism and acne. Follow medical advice to use medications such as dydrogesterone tablets, ethinylestradiol cyproterone acetate tablets, or spironolactone tablets to regulate hormone levels. At the same time, manage body weight and reduce intake of high-sugar and high-fat foods.
4. Hyperprolactinemia: Elevated prolactin levels suppress ovulation, leading to delayed menstruation or amenorrhea, possibly accompanied by galactorrhea (milk discharge from breasts). Follow medical advice to take medications such as bromocriptine mesylate tablets, vitamin B6 tablets, or cabergoline tablets to lower prolactin levels. Avoid prolonged breast stimulation and maintain a regular daily routine.
5. Endometrial adhesions: Intrauterine procedures or inflammation can damage the endometrium, causing adhesions that interfere with menstrual formation and shedding. Treatment typically involves hysteroscopic adhesion separation surgery. After surgery, an intrauterine device (IUD) may be placed, or sequential estrogen-progestogen therapy used to promote endometrial repair.
In daily life, avoid intense physical activity, keep the abdomen warm, and refrain from cold or raw foods during menstruation. Establish healthy lifestyle habits, undergo regular gynecological check-ups, monitor changes in the menstrual cycle, and maintain reproductive health through comprehensive调理 (regulation).
