Hello Viji Thanks for writing to us with your health concern. PCOS is a condition characterized by baseline hormonal imbalance. In this condition, the cause is unknown. The ovaries get studded with multiple small cyst like follicles. None of them gets matured every month, hence, ovulation is erratic and periods are irregular. Please remain sexually active around the time of ovulation to ensure pregnancy. The basic problem in PCOS is also one of underlying insulin resistance. Glycomet or Metformin is given for that. IT corrects the underlying metabolic imbalance that is always present in patients with PCOS. It is not to be prescribed only for lowering your blood sugar levels, it is given to almost every PCOS patient for regulating the cycles and preventing metabolic complications. Continue taking Eltroxin also. Aim to maintain ideal body weight, as even a 5 % loss of weight also will lead to regulation of cycles. In addition, please have a formal OGTT ( oral glucose tolerance test ) to diagnose glucose intolerance in PCOS, just fasting or random blood sugar levels will not be sufficient. All the best. Take care.
