#2. Jonah Lomu – Nephrotic Syndrome
He was diagnosed with nephrotic syndrome, a serious kidney disorder in 1995, and the disease had a significant impact on his playing career and wider life. By 2003 he was on dialysis and in 2004 underwent a kidney transplant. He then attempted a comeback but did not play international rugby again, and retired from professional rugby in 2007. He died unexpectedly on 18 November 2015 after suffering a heart attack associated with his kidney condition.
