Jeopardy! champion Brayden Smith's cause of death has been revealed after he died suddenly aged 24.

The contestant on the popular US game show, which has been airing for 37 seasons, had suffered health complications following an operation, according to a report.

Smith was hospitalised for days at a Southern Nevada hospital prior to his death on February 5, the Las Vegas Review-Journal reported.

Family members said Smith had died following surgery.

Smith had been a champion competitor during Alex Trebek's final episodes before the host lost his battle with pancreatic cancer.

He won five games in a row and more than $115,000 during his stint on the show, which was taped in October.

Smith's mother Debbie also paid tribute to him on Twitter.

"We are so grateful that Brayden was able to live out his dream on @jeopardy," she wrote on Twitter.

It comes after Trebek died in November.

He had hosted Jeopardy! since its debut in 1984, winning seven Daytime Emmy Awards for outstanding game show host.
