There are various symptoms associated with PCOS such as insulin sensitivity, low metabolism, difficulty in losing or gaining weight, hair loss, unhealthy skin, and digestive complaints. These are symptoms that appear because of some underlying reason and therefore cannot be treated superficially. Despite what a lot of cosmetic products claim, these symptoms can be controlled with your diet and lifestyle more than anything. If you are wondering why diet is focussed upon so much, it is for the nutrients that it provides – energy, nutrients like a variety of vitamins and minerals, that not only nourish your body but also help in controlling and managing the symptoms of PCOS.
