I apparently have 'typical' hormone levels for someone with PCOS (even though I had previously been told everything looked 'fine') so I suspect my testosterone levels are also high. I weigh 8 stone and am 5'4".
Most people with PCOS are overweight but there is a 'lean' version. If you are overweight and have excess hair with no periods, you are likely to get diagnosed in your teenage years. If you don't tick all of those boxes, you will struggle. Most doctors' answer to PCOS is to lose weight as it is caused by insulin resistance. Many think you just can't have it if you are thin. Not true.
Apparently the 'lean' version is a different type and unfortunately harder to get rid of. Obviously we can't just lose weight. I read that lean PCOS is hereditary and, no matter what form you have, you will have some form of insulin resistance (no matter what doctors say), which is why metformin works for so many women. I have even seen women on forums who had lean PCOS, they were tested for insulin resistance and it came back ok, but the doctor gave them metformin anyway 'as it would do no harm'. They got pregnant.
