Five years ago Sabet Choudhury donated a kidney to his mother. It transformed her life. Sabet, a BBC journalist, says the experience changed his life for the better too. He’s now fitter and healthier than before and he’s forged a closer relationship with his parents. Organ donation was never on his radar before his mother became so ill, but it’s an issue that’s very real to him now. In this, the first of three programmes, Sabet talks to Kay Hamilton, his Kidney Coordinator, who played such an important part in his donation journey – and someone he has kept in close contact with since his operation.
