Polycystic Ovary Syndrome (PCOS) is one of the common endocrine disorders among women of childbearing age. The most well-known consequence of PCOS is infertility caused by ovulatory dysfunction in reproductive-age women, yet people often overlook that PCOS mostly develops during adolescence.
To prevent long-term complications of adolescent PCOS, such as infertility, type 2 diabetes, metabolic syndrome, dyslipidemia, hypertension and endometrial carcinoma, diagnosis and intervention for this condition should commence in adolescence.
Four Major Symptoms That Cannot Be Ignored
Statistics show the incidence of adolescent PCOS ranges from 8.3% to 9.13% overseas, and approximately 5.74% in China. Although there is no universally recognized unified diagnostic criterion, adolescent girls presenting the following manifestations require early screening for PCOS:
1. Hirsutism of varying severity across the body, predominantly sexual hair: dense pubic hair extending to the perianal area and groin, fine upper lip whiskers, or long coarse hair around the areola.
2. Severe acne appearing in early adolescence that requires medical treatment or fails to respond to conventional therapies.
3. Failure to establish a regular menstrual cycle two years after menarche.
4. Excessive weight gain in adolescence accompanied by acanthosis nigricans, and/or a family history of metabolic syndrome or type 2 diabetes. Acanthosis nigricans presents as velvety, patchy hyperkeratotic gray-brown lesions on the posterior neck, armpits, vulva and groin.
Parents need not be overly anxious. Differential diagnosis against normal physiological changes of adolescence is required to confirm adolescent PCOS. A full panel of examinations under medical guidance is necessary, including pelvic ultrasound, sex hormone profiling, complete thyroid function tests, oral glucose tolerance test and insulin release test.
Early Intervention to Prevent Long-Term Complications
Acne, hirsutism, alopecia and obesity triggered by adolescent PCOS easily trigger inferiority complex in sensitive teenage girls. The disorder impairs adolescents’ social adaptation and mental health, and brings long-term complications including infertility, so early intervention is essential.
1. Weight loss and fat control via exercise and dietary adjustment
Take aerobic exercise for at least one hour, five times a week, such as jogging or brisk walking. Correct unhealthy eating habits, reduce mental stress, quit smoking, limit alcohol and caffeine intake, and consume more high-protein fish, eggs and vitamin-rich vegetables and fruits. Losing 8%–15% of baseline body weight within six months is the first-line therapy for PCOS, especially critical for overweight and obese adolescent PCOS patients. Medications and surgery shall not be adopted as primary weight-loss measures for teenage patients.
2. Menstrual regulation
To avoid endometrial lesions, if no menstruation occurs within three months, progesterone withdrawal bleeding or anti-androgen contraceptives may be prescribed by doctors to restore cyclic menstruation. Weight changes should be monitored during medication, and dosage adjusted when needed.
3. Medication targeting complications
For hyperinsulinemia or insulin resistance, oral insulin sensitizer metformin significantly improves glucose tolerance and lowers elevated androgen levels in obese adolescent PCOS patients with impaired glucose tolerance. Spironolactone can be used for anti-androgen therapy to treat hirsutism and acne. Regular rechecks of androgen levels are required during treatment for timely dose reduction or drug discontinuation.
4. Physical hair removal for hirsutism
Hirsutism imposes heavy psychological stress on adolescent females. Given the long hair growth cycle and prolonged medical treatment course (usually over six months), many patients prefer physical therapies for rapid cosmetic improvement. Shaving, waxing, tweezing and depilatory creams effectively improve appearance without aggravating hirsutism. Laser and electrocoagulation hair removal also deliver reliable therapeutic effects.
Special Attention to Mental Health
Adolescent females have unique psychosocial characteristics associated with PCOS; many patients develop anxiety and depression. Clinicians and families shall pay close attention to their psychological well-being and provide active professional mental intervention when necessary.
