Re: Insulin & periods.
Hi Abi!
Not sure if insulin can affect your period like that, but there is certainly some interaction between your blood sugar levels and the menstrual cycle. I was diagnosed with diabetes after going to the doctor with heavy, prolonged bleeding. The bleeding stopped as soon as my BG came under control. Also, in the week leading up to my period I find I need more insulin and my BG goes higher, but once the period starts, my BG falls low and I have to reduce my insulin. Not sure if that helps you at all, but maybe someone else will know more.
