My surgeon advised that it was wise to lose weight before surgery but if I was adamant that I wanted it done regardless then I didn’t have to…. In fact now I’ve had my surgery I’m more motivated than ever to lose weight and be healthy! I think it depends on whether your breasts contain fat tissue or not, mine were all glandular tissue so even if I lost weight my boobs wouldn’t get any smaller, whereas fat tissue can be lost through diet and exercise. May depend on the surgeon though, at a different clinic I was told to lose weight first but then went to MYA … Hope this helps! Xx
