Well, women with PCOS has a high tendency to have diabetes at some point in their life & they are advised to watch their cholesterol & sugar levels & also keep their weight in check. Surprisingly, PCOS mostly affect girls who have a family history of diabetes. You always carry the risk of insulin resistance as well with PCOS. Although your sugar levels are quite normal but you keep it in check if esp someone in your family has diabetes. But there are other symptoms of diabetes too & just having pins & needles alone doesn't mean that you've got diabetes. Other hallmark symptoms of diabetes also includes urinating a lot more than usual, drinking, binging as a result of low energy & lethargic feeling, dry skin & mouth, wounds not getting healed easily, etc. I also have been diagnosed with PCOS & last year my fasting blood sugar rose to 138 mg of dl which the doctor categorized in a diabetic stage & not even a prediabetic stage & later it was found out that it was due to insulin resistance & since then I've been hooked on biguanides to prevent the sugar levels from rising again although my gyne has now eliminated me from diabetes but also told me that I've insulin resistance & has a high risk of having diabetes so I've to keep taking it for the rest of my life but it also helps with PCOS too & doctor usually prescribes it to treat PCOS. Hope it helps.
