What are the reasons why polycystic ovary syndrome causes obesity?

Patient's question:

Why does polycystic ovary syndrome cause obesity

Doctor's answer:

Hello! Clinically, it is characterized by menstrual disorders, amenorrhea, anovulation, hirsutism, obesity, and infertility, with bilateral ovarian enlargement showing cystic changes, known as Polycystic Ovary Syndrome (PCOS). Its most significant feature is anovulation, so the ovaries only secrete estrogen and androgen, without secreting progesterone. Obesity is associated with excessive androgen levels, an increased proportion of unbound testosterone, and long-term estrogen stimulation.
For obesity related to this condition, a low-calorie diet and regular exercise are definitely necessary. However, targeting obesity alone is only treating the symptoms, not the root cause. Medications such as androgenic drugs and oral contraceptives are also required to control the condition, as they can inhibit hyperandrogenism in the ovaries. If infertility is also present, additional treatments must be combined.
Of course, controlling carbohydrate and fat intake, increasing exercise, and reducing weight undoubtedly help alleviate the condition. Wishing you good health!
