Diagnosis involves a thorough medical history and physical examination. Key steps include: - Medical History: Reviewing the patient's menstrual history, lifestyle, and any underlying health conditions. - Physical Examination: Assessing signs of hormonal imbalances, such as acne, hirsutism, or obesity. - Laboratory Tests: Blood tests to measure hormone levels, including thyroid function tests, prolactin levels, and androgens. - Imaging Studies: Ultrasound may be used to examine the ovaries and uterus for any abnormalities such as ovarian cysts.
