Ans: PCOS is a condition of the ovary that one is born with. You can optimize the hormonal imbalances in PCO, but the condition never factually reverses because it is a type of theory. So, lifestyle modifications and medication are sometimes necessary to ensure that regular ovulation happens with PCO. Lifestyle modification in terms of diet control, exercise, medication like metformin, MYO inositol. In exceptional cases, cyclical contraceptive pills, etc., may be needed to regulate cycles and ensure hormonal imbalances in PCO, PCOS with androgen excess, men need medication like spironolactone and aldactone to optimize their hormonal imbalances. Weight loss often helps to optimize the condition and resume ovulation in cases of PCOS. Since you weigh 64 kilos, it might be a good idea to lose around 7 to 8 kgs of weight, which will help further improve the cycles.
