My GP thinks I probably had PCOS based on some symptoms including my difficulty losing weight but I've never been officially diagnosed as such.
I have lost weight well and noticed I don't have problems with hair on my chin and belly like I did. I used to have very bad periods but was on medication that stopped them completely before the WLS. I'm having surgery soon and will then try coming off the meds so will see what's happening there. My acne has cleared up too. I hope that's some use but I'm sure there's official sufferers around who can also share their experiences.
