When I was younger I had an eating disorder I was constantly gaining and losing weight which is why now I was advised on getting implants with uplift, major saggy boobs!! 5’8” 10.7stone and surgeon suggests a 545CC implant with uplift. He has made me aware that I may need a revision in 6months - 1 year due to the “waterfall affect” Please can someone tell me if this is safe? Will I need to keep having revisions to fix this possibly deformity if it occurs? Thank you!
