Eating a specific PCOS Fertility Diet is one of the best things you can do to improve your chances of becoming pregnant.The biggest part of the problem with PCOS is insulin resistance. Resistance to insulin increases the body’s insulin levels which can have a negative affect on ovulation by limiting the maturation process of an egg and in turn delaying or preventing ovulation from taking place. This has a direct impact on your fertility and ability to conceive. Women with insulin resistance are 4-5 times more likely to have a miscarriage. PCOS is also a huge red flag for the beginning of type 2 diabetes. I do not say all this to scare you, but I do want you to know that this is a serious matter. Fortunately, there are many natural options you can do on your own to turn this all around. The biggest step you can take is to change your diet to a PCOS diet.
