Hi, I'm wondering if someone might be able to shed some light on the issues I'm having with my treatment. I have been diagnosed with PCOS for more then 5 years now. Originally I started on the regular Metformin but due to gastritis could not continue. While I was on it I lost weight my monthly cycle was regular. Some time later my symptoms re-occurred. I began taking Metformin XR (slow release) and suffered no side effects. However, my symptoms are getting worse and the medication is not helping. I am on a low fat low carb diet and get regular exercise daily. Nothing seems to work and my weight is ever increasing. It's something I need to get on top of as there is a strong history of diabetes in my family. I also suffer from palpitations from hormonal imbalance. I've had these checked out and the cardiologists isn't worried.
