Thank you for your question. PCOD is a lifestyle disease that occurs because of a combination of sedentary lifestyle, overeating or junk food or processed food, lack of sleep and greater stress and poor nutrition. This leads to a series of hormonal abnormalities of which insulin resistance is primary. The problem cannot be cured but can be managed to reduce its effects. The complex of changes increases the lifetime risk of developing health problems such as infertility due to anovulation, diabetes, hypertension, cancers of the endometrium and breast. Managing exercise and ideal weight are the keys to keeping the ovaries healthy. Your doctor can guide you further. You can also read about it on www.patient.co.uk and www.rcog.org patient leaflets.
