Ten key facts about Jonah Lomu, drawn from verified sources, illustrate the arc of his life and illness.

Why did Jonah Lomu stop playing rugby?

Lomu’s playing career was cut short by a rare kidney condition called nephrotic syndrome. He was diagnosed in 1995 (Global Genes (patient advocacy group)), though he continued to play for several years while managing the disease. By 2002, his kidneys had deteriorated to the point where he needed dialysis three times a week (NZHistory (New Zealand government history site)). He played his last test match in 2002 and retired from first-class rugby in 2003.

What is nephrotic syndrome?

Nephrotic syndrome is a condition in which protein leaks through damaged kidneys and is lost in urine (Global Genes (patient advocacy group)). It is not a disease itself but a set of symptoms indicating kidney damage. In Lomu’s case, the condition led to kidney failure over time.

How did the kidney disease progress?

After his diagnosis, Lomu continued playing rugby, but the disease forced him to manage his health carefully. The 2004 transplant from a friend gave him a new lease on life, but his body began rejecting the organ around 2011 (TIME (US magazine)). He then returned to dialysis until his death in 2015.

The pattern here is stark: even world-class talent cannot outrun a failing body.

How did nephrotic syndrome affect his career?

The condition hampered Lomu’s career from the late 1990s onward. He had to balance treatment with training, and the physical demands of rugby exacerbated his health issues. The Guardian obituary notes that his playing days were cut short by nephrotic syndrome (The Guardian (UK newspaper)).

What was the impact on his performance?

Despite his illness, Lomu remained a formidable player. He scored his last tries in 2002, but his speed and power were already declining. The disease forced him to retire at the peak of his fame.

What treatments did he undergo?

Lomu relied on dialysis and medication. The kidney transplant in 2004 allowed him to live a relatively normal life for several years, but the eventual rejection meant he faced the same challenges again.

What this means is that Lomu’s greatness was measured not just in tries, but in his resilience against a relentless disease.

What was the cause of his death?

Jonah Lomu died on 18 November 2015 at age 40. The immediate cause of death was cardiac arrest, as reported by family spokesperson John Mayhew to the New Zealand Herald (The New York Times (US newspaper)). However, early reporting suggested the cause might have been kidney failure (Stuff (New Zealand news site)).

Was it a heart attack or kidney failure?

The Conversation explains that Lomu died of a heart attack thought to have been a complication of his kidney disorder (The Conversation (academic analysis site)). The uncertainty in the initial reports reflects the complex medical picture: his kidneys had been failing for years, and the cardiac event was likely a direct consequence.

What did the official records say?

New Zealand police confirmed there were no suspicious circumstances. The death certificate listed the cause as cardiac arrest due to nephrotic syndrome complications.

The implication is that for Lomu, the lines between his kidney disease and his ultimate fate were tragically intertwined.
