PCOS: Complete Guide to Symptoms, Causes, Diagnosis and Treatment
Quick Summary
Polycystic Ovary Syndrome (PCOS) is a hormonal disorder affecting women of reproductive age, characterised by irregular menstrual cycles, excess androgen (male hormones), and metabolic disturbances. Common symptoms include irregular periods, acne, excess facial hair, weight gain, and difficulty conceiving. Management includes lifestyle modification, diet optimisation, hormonal therapy, insulin-sensitising medications, and long-term metabolic monitoring.
Early diagnosis and personalised treatment significantly improve hormonal balance and reproductive health.
What is PCOS?
Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting women worldwide. It affects approximately 1 in 10 women of reproductive age and often begins during adolescence.
PCOS affects multiple systems in the body, including:
- Reproductive hormones
- Metabolism
- Skin and hair
- Psychological health
In PCOS, hormonal imbalance disrupts normal ovulation, causing irregular periods and increased androgen production.
Despite its name, not all women with PCOS have ovarian cysts. The condition is primarily a hormonal and metabolic disorder.
Why PCOS is Increasing Today?
Doctors worldwide have noticed a significant rise in PCOS cases, particularly among young women and teenagers.
Several modern lifestyle factors contribute to this increase:
- Sedentary lifestyle
- High sugar and processed food intake
- Increased screen time
- Poor sleep patterns
- Chronic stress
- Obesity and insulin resistance
Urban populations, including cities like Gurgaon, show a higher prevalence of PCOS due to these lifestyle patterns.
What are the symptoms of PCOS?
PCOS symptoms can vary widely between individuals. Some women experience mild symptoms while others may have multiple manifestations.
Menstrual Symptoms
- Irregular menstrual cycles
- Delayed periods
- Heavy menstrual bleeding
- Absence of periods
- Irregular ovulation is one of the earliest signs of PCOS.
Skin and Hair Symptoms
Excess androgen hormones cause several skin and hair changes.
Common symptoms include:
- Severe acne
- Excess facial hair
- Increased body hair growth
- Hair thinning on scalp
These symptoms occur due to increased androgen activity.
Metabolic Symptoms
PCOS is closely associated with metabolic disturbances.
Common metabolic signs include:
- Weight gain
- Difficulty losing weight
- Insulin resistance
- Dark patches on neck or underarms (acanthosis nigricans)
Reproductive Symptoms
Some women discover PCOS when they try to conceive.
Possible reproductive symptoms include:
- Difficulty ovulating
- Irregular ovulation
- Subfertility
However, many women with PCOS can conceive successfully with proper treatment.
What are the causes of PCOS?
The exact cause of PCOS is not completely understood. Research suggests that multiple factors including genetics and environmental contribute to the condition.
Insulin Resistance
Insulin resistance is one of the most important underlying mechanisms in PCOS.
When cells become resistant to insulin, the body produces more insulin to compensate.
High insulin levels stimulate the ovaries to produce excess androgen hormones, disrupting ovulation.
Genetic Factors
PCOS often runs in families.
Women with a family history of the following conditions may have higher risk:
- PCOS
- Type 2 diabetes
- Obesity
- Metabolic syndrome
Hormonal Imbalance
Several hormonal disturbances occur in PCOS, including:
- Increased androgen levels
- Altered LH/FSH ratio
- Impaired ovulation
These hormonal changes disrupt the menstrual cycle.
How PCOS is Diagnosed?
Diagnosis of PCOS involves clinical evaluation, laboratory tests, and imaging.
Doctors commonly use the Rotterdam Criteria, which require two out of three features:
- Irregular ovulation
- Clinical or biochemical hyperandrogenism
- Polycystic ovarian morphology on ultrasound
Other conditions that mimic PCOS must be excluded before confirming diagnosis.
What are the tests recommended for PCOS Evaluation?
A comprehensive PCOS evaluation may include:
Hormonal Tests
- LH and FSH
- Testosterone
- DHEAS
- Prolactin
- Thyroid profile
Metabolic Tests
- Fasting insulin
- Blood sugar
- Lipid profile
Imaging
- Pelvic ultrasound
These tests help assess both reproductive and metabolic health.
What are long-term health risks of PCOS?
If untreated, PCOS can increase the risk of several health conditions.
These include:
- Type 2 diabetes
- Metabolic syndrome
- Cardiovascular disease
- Endometrial hyperplasia
- Infertility
- Obesity
- Depression
Early diagnosis and treatment help reverse PCOS to PCOD and reduce long-term risks.
