PCOS and Adolescent Weight
Polycystic ovary syndrome (PCOS) is closely linked to weight and metabolic health in adolescent girls, and is one of the more common hormonal conditions we evaluate alongside
pediatric obesity. At
Nova Physician Wellness Center, our physicians coordinate weight management with the broader hormonal picture of PCOS.
We're honored to support families across Northern Virginia and Maryland.
What Is PCOS?
PCOS is a hormonal condition that affects roughly 8 to 13% of adolescent girls, involving irregular periods and signs of excess androgen (male hormone) activity, such as acne or excess hair growth. Diagnosing PCOS during adolescence can be tricky, since normal puberty can look similar. Current international guidelines recommend diagnosis based on a pattern of irregular menstrual cycles, defined relative to how long it's been since a girl's first period, together with clinical or lab evidence of excess androgens, after ruling out other causes.
Signs & Symptoms Parents May Notice
- Irregular, infrequent, or absent periods
- Acne that doesn't respond to typical treatment
- Excess hair growth on the face, chest, or back
- Weight gain, especially around the abdomen
- Difficulty losing weight despite lifestyle changes
Why Early Evaluation Matters
PCOS is closely connected to insulin resistance and weight, and each can make the others harder to manage. Left unaddressed, PCOS can carry long-term risks including type 2 diabetes, high cholesterol, and fertility challenges later in life. Evaluating and treating PCOS during adolescence, rather than waiting, gives girls a better chance at healthier long-term hormonal and metabolic health.
How We Evaluate Your Child
Diagnosis is based on menstrual history, physical exam, and bloodwork, ruling out other conditions that can look similar.
- Menstrual cycle history relative to years since first period
- Physical exam for signs of excess androgen activity
- Bloodwork to check hormone levels and rule out other causes
- Screening for related metabolic conditions, including insulin resistance
How Is It Treated?
Treatment is individualized and often includes a combination of approaches.
Lifestyle-based care, nutrition, physical activity, and weight management, is typically the first step, since even modest weight changes can improve PCOS symptoms. Depending on your daughter's needs, treatment may also include hormonal therapy to regulate periods or manage androgen symptoms, or metformin to address insulin resistance.
Benefits of Early Treatment
- More regular menstrual cycles
- Improved acne and reduced excess hair growth
- Better insulin sensitivity and metabolic health
- A stronger foundation for long-term reproductive and hormonal health

Supporting Your Child Every Step of the Way
We understand a PCOS diagnosis can feel overwhelming for both girls and their parents. Our team takes time to explain what's happening, answer questions, and build a plan the
whole family can support.
Frequently Asked Questions
How common is PCOS in teenagers?
PCOS affects roughly 8 to 13% of women and girls of reproductive age, making it one of the most common hormonal conditions in adolescence.
How is PCOS diagnosed in teens, since periods are often irregular after puberty anyway?
Because irregular periods are common in the first few years after a girl's first period, diagnosis relies on specific criteria based on how long her periods have been irregular relative to that first period, combined with signs of excess androgen activity.
Does my daughter need to lose weight to treat PCOS?
Not necessarily, though for girls with overweight or obesity, even modest, sustainable improvements in weight can meaningfully improve PCOS symptoms as part of a broader treatment plan.
Will my daughter need medication?
It depends on her symptoms and goals. Some girls do well with lifestyle changes alone, while others benefit from hormonal therapy or metformin as part of an individualized plan.
Can PCOS affect my daughter's future fertility?
PCOS is a leading cause of fertility challenges in adulthood, but early evaluation and treatment can improve long-term reproductive and metabolic health.
