It is widely accepted in the medical community that the first treatment of choice for PCOS should be lifestyle changes such as diet and exercise. Effects can be profound, in terms of reducing both the symptoms and the long-term risks associated with the syndrome. Earlier this year I posted a link to an article on intermittent low carb dieting, which has shown positive results in terms of weight loss and also its insulin-lowering effect (insulin resistance is typical in women with PCOS, with the potential to progress to diabetes if left unchecked). Do check out the article for more information if you think this may be of benefit to you:

PCOS is an incredibly complex condition that affects women in a wide variety of ways, both physically and emotionally. You may not even realise you have it - many women have very few symptoms and only find out when they visit their GP due to problems becoming pregnant. If you have any of the symptoms listed in the NHS article and are concerned by these, it is worth a visit to your GP for further tests.
Women with PCOS: want to tackle your condition with a new exercise regime but muscular/joint pain or stiffness is stopping you? An osteopath might be able to help.
