PCOS is a very complex syndromic group and there is no single diagnostic criteria for it worldwide. PCO (polycystic ovaries) and PCOS (polycystic ovary syndrome) are two concepts. The latest consensus of the International Society of Gynecologic Endocrinology (2003) considers that there are 1) scanty menstruation and non-ovulation; 2) high androgenic changes such as obesity, hirsutism and acne; and 3) ultrasound suggesting ovarian follicles of more than 10 in size. From the situation you reflect, it should be enough to meet the diagnostic criteria. The treatment of this disease is a bit tricky and currently focuses on solving fertility problems. If you have irregular menstruation and LH/FSH > 2.5, it is better to check fasting insulin/glucose (because half of the patients have insulin resistance), and you should be treated with Daine-35 (the disease itself causes progressive obesity), you should calculate your body mass index and BMI = weight (kg)/height (m)2 (square), ideally at 19-23. -23, if it is exceeded, then losing weight is also a treatment, some weight comes down and spontaneous ovulation is restored.
