I have not had my VSG yet, but am in 4 weeks. I was told forthright thta women with PCOS have a more difficult time losing, so where a "normal" person might lose 60% someone with PCOS might be more likely to lose 45%, it will be more difficult and take longer. Also more difficult to maintain, you will have to be more diligent.
I am glad I was told this ahead of time, so I won't be disappointed when the time comes.
Good luck ladies!
