My aunt had type 1, which she developed as a teen
and was insulin dependent her entire life,
and she also had
PCOS. She died at age 58 from heart disease.
I too have PCOS, but I have type 2 diabetes. After years of dealing with low blood sugar and many other debilitating symptoms, including fatigue and severe PMS, I became diabetic overnight.
I'm sorry to say that there is no cure for PCOS. It can only be treated.
