Known medically as an abdominoplasty, tummy tucks improve the appearance of the stomach.
Surgeons remove excess skin and fat from the abdomen, and tighten connective tissues.
The end result is a more toned look. Many women, and men, have the operation to boost their body image.
A tummy tuck is also the go-to option for women who have given birth and have a prolonged 'mummy tummy'.
The surgery repairs the rectus diastasis - two abdominal muscles than can separate during pregnancy.
Figures show nearly 130,000 tummy tucks were performed in the US last year. There are nearly 3,000 performed privately in the UK each year.
