What are the reasons for delayed menstruation?

Delayed menstruation may be related to mental stress, excessive dieting, polycystic ovary syndrome, hyperprolactinemia, premature ovarian failure and other factors. Delayed menstruation is usually caused by endocrine disorders, organic diseases or changes in physiological status, and intervention measures need to be taken based on the specific reasons.

1. Mental pressure

Chronic anxiety or stress may inhibit hypothalamic function, resulting in decreased secretion of gonadotropin-releasing hormone. This condition may be accompanied by insomnia and mood swings, and usually does not require medication. It can be alleviated through psychological consultation and regular work and rest. It is recommended to do 30 minutes of aerobic exercise every day to help regulate neuroendocrine.

2. Excessive dieting

A body fat rate below 17% may cause amenorrhea because adipose tissue is involved in estrogen synthesis. Delayed menstruation caused by rapid weight loss is often accompanied by fatigue and hair loss. It is necessary to gradually restore a balanced diet and increase the intake of high-quality protein and healthy fats, such as eggs, avocados, etc.

3. Polycystic ovary syndrome

The disease is associated with insulin resistance and manifests as oligomenorrhea, acne, and hirsutism. It may be related to the combined effect of genetic and environmental factors. Ethinyl estradiol and cyproterone tablets can be used as directed by the doctor to regulate the cycle, and metformin tablets can be used to improve metabolism. Ultrasound examination shows polycystic changes in the ovaries.

4. Hyperprolactinemia

Pituitary tumors or drug factors cause prolactin to increase and inhibit follicle development. Nipple discharge and headache may occur, and the cause needs to be diagnosed through MRI. Bromocriptine mesylate tablets are commonly used for treatment, and changes in hormone levels need to be monitored regularly during medication.

5. Premature ovarian failure

Follicular depletion before the age of 40 may trigger amenorrhea and is related to autoimmune or iatrogenic injury. With symptoms such as hot flashes and vaginal dryness, estrogen and progesterone replacement therapy is required, such as estradiol valerate tablets combined with progesterone capsules. It is recommended to have a bone density test every year to prevent osteoporosis.

If menstruation is delayed for more than 3 months, you need to seek medical examination, including sex hormones, thyroid function and pelvic ultrasound. Maintain moderate exercise on a daily basis, avoid extreme weight loss, and manage stress levels. Recording basal body temperature and menstrual cycle can help doctors determine ovulation status. If menopause occurs after pregnancy is ruled out, it is recommended to seek medical treatment as soon as possible to determine the cause.
