Polycystic Ovary Syndrome (PCOS): Symptoms and Nutrition

Polycystic ovary syndrome (PCOS) is a hormonal and metabolic condition that can affect menstrual cycles, ovulation, skin and long-term health. “PCOD” is sometimes used in conversation, but PCOS is the term used in the World Health Organization (WHO) fact sheet and international guideline cited below. A clinician can assess symptoms and exclude other causes.

Symptoms and treatment needs vary from person to person.

What are common signs?

Periods may be irregular or absent. Some people experience acne, increased facial or body hair, hair thinning or difficulty conceiving. PCOS may also be associated with insulin resistance, type 2 diabetes and cardiovascular risk factors. Symptoms alone do not establish a diagnosis.

How is PCOS diagnosed?

Health professionals consider menstrual history, signs or blood levels of excess androgens, and sometimes ovarian ultrasound, while excluding other causes. Not everyone with PCOS has visible ovarian cysts, and ultrasound findings alone do not prove PCOS. Diagnostic approaches can differ by age, so discuss your results with a gynecologist or other qualified clinician.

Is there a specific PCOS diet?

The 2023 international evidence-based guideline does not support one particular diet composition as superior for PCOS outcomes. Sustainable healthy eating and physical activity can benefit general and metabolic health even without weight loss. Choose a varied pattern of vegetables, fruit, whole grains, beans, protein foods and unsaturated fats that fits your preferences and medical needs. Avoid claims that one spice, supplement or restrictive plan can cure PCOS.

Neither tool treats PCOS or accounts for pregnancy and individual medical needs.

What treatment might be needed?

Care depends on your symptoms, metabolic health and pregnancy goals. Medical options may address irregular periods, acne or fertility concerns. Your clinician may also recommend checks for blood glucose, blood pressure and lipids. Food choices can support care but do not replace assessment or prescribed treatment.
