    Menstruation is usually very accurate. This delay may be related to mental stress, sudden weight changes, drug effects, polycystic ovary syndrome, thyroid dysfunction, etc. Intervention can be made by adjusting work and rest, seeking medical examination, etc.

    1. Mental pressure

    Chronic anxiety or mood swings may inhibit hypothalamic function, resulting in decreased secretion of gonadotropin-releasing hormone. Typical manifestations include menstrual cycle disorders accompanied by insomnia and headaches, which can be alleviated through mindfulness training and psychological consultation. If there is no improvement for more than 3 months, organic diseases such as pituitary tumors need to be investigated.

    2. Sudden change in weight

    Losing more than 10% of your body weight in a short period of time may cause amenorrhea, and insufficient adipose tissue will affect estrogen synthesis. It is common in people who over-diet, and is accompanied by symptoms such as chills and hair loss. It is recommended to gradually restore a balanced diet, increase calorie intake by 300-500 calories per day, and use estradiol valerate tablets to supplement hormones if necessary.

    3. Drug effects

    Emergency contraceptive pills containing large doses of progestins may interfere with the cycle, and antidepressants such as fluoxetine hydrochloride capsules may also affect neurotransmitter regulation. Usually, it can recover on its own within 1-2 cycles after stopping the medication, during which time it can be adjusted with Motherwort granules. The possibility of pregnancy must be ruled out before using progesterone capsules.

    4. Polycystic ovary syndrome

    Excessive androgens inhibit follicle development, and ultrasound shows polycystic changes in the ovaries. Often accompanied by acne and hirsutism, six items of sex hormones need to be tested. For treatment, ethinyl estradiol and cyproterone tablets can be used to adjust the cycle, and metformin sustained-release tablets can be used to improve insulin resistance.

    5. Abnormal thyroid function

    Hyperthyroidism or hypothyroidism will interfere with sex hormone metabolism. When the abnormal TSH value exceeds 10mIU/L, the probability of menstrual disorders increases significantly. Thyroid ultrasound and antibodies need to be checked. Patients with hyperthyroidism can use propylthiouracil tablets, and patients with hypothyroidism need levothyroxine sodium tablets for replacement treatment.

    It is recommended to record basal body temperature to monitor ovulation and avoid strenuous exercise or sudden changes in eating habits. If the pregnancy is delayed for more than 7 days, a pregnancy test and gynecological ultrasound are required. Women over 45 years old should check for perimenopausal changes. Daily drinking of rose tea can soothe the liver and relieve depression, and ensure 7-8 hours of sleep a day to help restore hormone rhythm.
