A very high percentage of women with PCOS [Poly Cystic Ovarian Syndrome] have Insulin Resistance and that increases their susceptibility for type 2 Diabetes. It has nothing to do with the amount of sugar they ate as children. It's hormonal. Both overweight, 'normal' weight and underweight women who have PCOS can develop insulin resistance.

Having said that though, some people can get their insulin resistance under control and find they don't need insulin medication. Diet and exercize can be really helpful but it's very, very complicated for some people.

My understanding of the Metformin recall was that the extended release was contaminated. It's really important that if people take Metformin that they talk to their doctors about this and not just stop taking it.
