Non-stop singing after winning “American Idol” last year was not beneficial to Jordin Sparks, who might lose her voice due to what was described as an acute vocal cord hemorrhage condition.

The injury usually occurs in people who overuse their vocal chords, due to their profession. Such people include attorneys, teachers or singers. A vocal cord hemorrhage is when a blood vessel on the vocal cord ruptures. It can result in permanent vocal cord damage, so it is important that people suffering from this condition have absolute voice rest.

Numerous singers, including Steven Tyler of Aerosmith, Elton John and Jessica Simpson, have suffered vocal injuries, which temporarily affected their careers.

The 2007 “American Idol” winner had to cancel three shows during the weekend, including the opening night of Grammy Award-winning Alicia Keys’ tour, when she was supposed to be the opening act. Still, the singer is expected to rejoin Keys on her tour in May or even sooner, depending on how fast her injury heals. The tour, which started Saturday in Virginia, will continue until July.

“Jordin Sparks is on vocal rest and is expected to make a full and complete recovery. She looks forward to joining Alicia Keys on tour in May,” read a statement released by 19/Jive Records. “Sparks has been going nonstop over the past two years, and now she is going through the normal course of learning how to manage and care for her voice.”

The first news about Sparks’ vocal problems was revealed by Penn State University, which announced last week the cancellation of a Sparks concert that had been established for Sunday.

The youngest “American Idol” winner (Sparks was 17 when she won the sixth season of the talent contest show) released two hit singles, “Tattoo” and “No Air,” since her victory that made her famous. Her self-titled album also made it in the top ten on the charts.

Earlier this month, Sparks appeared on Idol’s charity fundraising show, “Idol Gives Back,” where she performed, together with Chris Brown, their hit “No Air.”
