Is there a hormonal or physiological change after a tummy tuck or body lift that causes intense increased sexual desire?

During my recovery after a tummy tuck and another patient's recovery after a body lift, we both experienced intense increased sexual desire. I stress that this was early in recovery when the improved physical and psychological changes had not yet taken place. So I rule out the logical conclusion that our newly beautiful bodies caused increased libido in the weeks after surgery. I often have wondered if removing the fat caused a hormonal or physiological change that resulted in intense sex drive.
