Yalda Valinejad of Iran, who won a gold medal in taekwondo at the Buenos Aires 2018 Youth Olympic Games, has been given a two-year ban due to an anti-doping violation.

According to Iranian publication Tehran Times, Valinejad returned an adverse analytical finding in her sample for the prohibited substance furosemide.

Furosemide is a loop diuretic medication used to treat fluid build-up due to ailments such as heart failure, liver scarring or kidney disease.

It is on the World Anti-Doping Agency's list of prohibited substances as it can be used by athletes as a masking agent for performance-enhancing drugs, as well as rapidly getting rid of water for weight loss.

This ban from June 22 2021 is set to run until June 21 2023.

The governing body for the sport, World Taekwondo confirmed the suspension to insidethegames in a statement.

"World Taekwondo was in contact with the Iran National Anti-Doping Organisation who confirmed that Yalda Valinejad has been suspended for two years," said a spokesperson.

"World Taekwondo is committed to implementing a robust anti-doping programme and ensuring the protection of clean athletes."

Valinejad won the gold medal at the Youth Olympics three years ago, having won the women's under-63 kilogram category final against her main foe that year, Nadica Bozanic of Serbia.

Bozanic had defeated her in the quarter-finals of the Youth World Championships in 2018.

Valinejad made her senior debut at the World Taekwondo Championships in Manchester in 2019 in the women's under-62kg, but was defeated by Caroline Gomes dos Santos of Brazil in the first round.

The 19-year-old will be eligible to compete again at the age of 21.
