NEW YORK (Reuters) - Olympic champion Sunisa Lee has said the kidney disease that threatened her gymnastics career is in remission and she feels better than ever as she bids for a spot on the U.S. team for this year's Paris Games.

The 21-year-old American, who won the all-around gold at the Tokyo Olympics, revealed late last year that the disease caused her face, fingers and legs to swell and made it difficult at times to even get out of bed.
