Jeannie Mai pulled out of Dancing with the Stars after falling ill with epiglottitis, an infection of the throat.
The 41-year-old TV personality left the reality TV competition series after seeking medical attention for the potentially life-threatening inflammatory condition that can cause swelling and block airflow to the lungs, ABC reported on Monday.
Symptoms of epiglottitis are fever, sore throat, difficulty swallowing, or difficulty breathing.
"My doctors discovered a health concern with my throat which requires immediate attention and surgery," she said in a statement to Good Morning America.
"I am heartbroken that my DWTS journey has to end here. I have pushed myself to new limits physically and mentally, and I am so proud of how far we’ve come."
Jeannie was competing with professional dancer Brandon Armstrong on the show and, following her sudden departure, producers have opted to only eliminate one couple from the show this week.
"Jeannie has inspired us, along with millions of fans, with her energy and dedication," they added in a statement. "We wish her a full and speedy recovery. Since Jeannie had to withdraw from the competition, tonight’s show will feature the eight remaining couples and a single elimination."
Rapper Nelly, Selling Sunset's Chrishell Stause, Backstreet Boys singer AJ McLean and Disney Channel actress Skai Jackson are among those competing in the current 29th season.
