The 20-year-old professional dancer has been diagnosed with endometriosis, a common condition in which tissue from the uterus lining grows outside the uterus, causing painful cysts and possibly infertility.

Hough went to Cedars-Sinai Medical Center following the last week’s live results show and later said she had a stomach ache and was feeling fine.

An announcement about Hough’s immediate future on ABC’s popular dance competition was expected during Monday’s show, where she was scheduled to perform a samba with partner and “Hannah Montana” actor Cody Linley.
