Leg-lengthening surgery was once reserved for people with a serious injury or physical deformity. But now more people are undergoing the procedure simply because they want to be taller.

BBC journalist Tom Brada explains what the operation entails, the risks it carries, and the costs that patients incur. We also hear from Daniel, a man who underwent the procedure. He describes why he wanted to be taller, what his surgery and recovery were like, and whether it was worth it.
