Hello, Firstly, let me say that PCOD is seen in more and more women now-a-days and being a hormonal disorder, is easily rectified in the majority with simple medication and change of life style. If you wish to try natural methods, try to maintain a healthy BMI, do regular exercise, eat fresh fruits, fresh vegetables and take plenty of liquids and remove stress through meditation. Metformin helps to correct insulin resistance and thereby induces ovulation. This helps many by correcting irregular menstrual cycles. Hope you find this information useful.
