A surgical fat transfer is cosmetic surgery to move fat from one part of the body to another. It’s also known as a “fat graft” or “lipomodelling”. The aim is to remove unwanted fat from an area of the body, such as the tummy or thighs, and use it to smooth or increase the size of another area, such as the breasts or bottom. A surgical fat transfer involving the bottom is often known as a Brazilian butt lift (BBL). Having a surgical fat transfer is a big decision. It can be expensive, the results cannot be guaranteed, and there are risks. It’s a good idea to explore the other options for losing fat such as the non-surgical NHS weight loss plan before you go ahead.
