Polycystic Ovary Syndrome (PCOS) is a common endocrine and metabolic disorder that affects the female reproductive system and overall health. Its symptoms are diverse and vary greatly among individuals, potentially including reproductive, dermatological, physical, and metabolic abnormalities. These symptoms may gradually manifest during adolescence or early reproductive years, but some patients may remain undiagnosed for years, increasing the risk of complications.
The severity of symptoms is closely related to individual hormone levels, genetic background, and lifestyle. Early detection and accurate diagnosis are crucial for effective disease management. The following provides a detailed overview of typical symptoms at various stages, their trends, and when to seek professional medical evaluation.
Approximately 70-80% of patients initially seek medical attention due to menstrual issues, including prolonged cycles (over 35 days), reduced menstrual flow, or amenorrhea. Some may experience irregular intervals between periods or sudden heavy bleeding. These ovulatory disturbances are related to hyperandrogenism and impaired follicular development.
Early signs may include mild hair abnormalities, such as hirsutism on the upper lip, jawline, or chest. About 30% of patients notice darkened skin patches, commonly on the neck, axillae, and inner thighs, known as acanthosis nigricans. These signs can be mistaken for common skin issues, leading to delayed diagnosis.
Approximately 50% of patients experience weight gain or redistribution of body fat early in the disease, especially around the abdomen and hips. Despite maintaining usual diet and exercise routines, waist circumference may gradually increase, which is associated with insulin resistance and abnormal fat metabolism.
Over 50% of patients exhibit insulin resistance, leading to elevated fasting blood glucose or prediabetes. Fat distribution tends to be "apple-shaped," with waist circumference exceeding 80 cm, increasing the risk of metabolic syndrome. Some may develop abnormal fat accumulation in the neck or axillae.
Besides hirsutism, about 30% of patients develop darkened skin patches (acanthosis nigricans). A minority may experience oily skin, keratosis pilaris (commonly called "chicken skin"), and other associated symptoms.
Untreated patients may develop full-blown metabolic syndrome after 10-15 years, including hyperglycemia, hypertension, and dyslipidemia. Insulin resistance worsens over time, increasing the risk of type 2 diabetes by 2-4 times.
Prolonged anovulation can lead to abnormal endometrial proliferation, increasing the risk of endometrial cancer. Ovarian decline may cause perimenopausal symptoms such as hot flashes and mood swings before age 40.
Adolescents often present with irregular menstruation, adults with infertility issues, and middle-aged women with metabolic symptoms. The severity of symptoms may fluctuate with stress, dietary changes, or aging.
If any of the following occur, seek medical care immediately:
If any of the following are met, professional assessment is recommended:
Patients diagnosed should have metabolic indicators monitored every 6-12 months, including fasting blood glucose, lipid profile, and hormone levels. Doctors may adjust treatment plans based on symptom changes to prevent long-term complications.
It is recommended to engage in moderate-intensity aerobic exercise combined with resistance training, such as brisk walking, swimming, or weightlifting, for at least 150 minutes per week. Avoid excessive vigorous exercise to prevent stress hormone elevation, which can worsen metabolic abnormalities. Warm-up and carbohydrate intake before and after exercise are important to maintain blood sugar stability.
Which nutrients in the diet should be emphasized to control PCOS symptoms?Prioritize high-fiber foods (such as whole grains and vegetables) to improve insulin resistance; Omega-3 fatty acids (found in fatty fish and chia seeds) can reduce inflammation. Avoid refined sugars and trans fats, and consider supplementing magnesium and vitamin D, deficiencies of which are often linked to PCOS.
What are the differences between medication and surgical treatments for PCOS?Medications are mainly used to regulate hormonal imbalance (e.g., oral contraceptives) or improve metabolism (e.g., metformin), while ovarian drilling or laparoscopic surgery are reserved for severe ovulatory failure unresponsive to medication. Treatment choices depend on age, fertility desires, and associated metabolic issues.
How does sleep quality affect PCOS symptoms?Lack of sleep increases cortisol levels, which can exacerbate insulin resistance and hyperandrogenism. Maintaining 7-9 hours of deep sleep per night and avoiding screen time before bed can help regulate hormones and improve symptoms.
What health adjustments should women planning pregnancy with PCOS make in advance?It is advisable to induce ovulation with medications (such as clomiphene) 3-6 months prior, control weight to BMI 20-24, and monitor blood glucose levels. Using insulin sensitizers when necessary can improve natural conception rates and reduce pregnancy complications.
