Hello, I had my follow Glucose Tolerance Test yesterday. Its the one where I've been on Metformin for about 8 months, so it should be better the last one where I was not on metformin and not yet officially diagnosed. Because of the fasting and metformin does make your digestive tract a little more sensitive, I vomited after the first test - a bit embarassing but it was only water as that was the only thing i had had since 9pm the night before!! Nurse said the next time I should miss my metformin from the night before haha. So 2 boring hours in the waiting room. I will know my results next Thursday when I go to the endo. She also has my latest Thyroid, hormone and the GTT test results. I am down from 79 to 69kgs so things should be looking good but my hair is still steadily falling .. unfortunately what can you do .. I know its Androgenetic Alopecia but was hoping if free testosterone was down and SHGB up... it may slow down.... and I may keep what I've got much longer... Being lighter and losing the weight has definately slowed the hairloss so i reccommend any girl who think she may have PCOS insulin Resistance get diagnosed as it really gives you a kick in the bum to go on metformin and lose the weight.
