Celine Dion, known for her powerful and inspiring vocals, is showcasing an equally resilient spirit in her current battle against a debilitating health condition.

The acclaimed singer of "My Heart Will Go On" recently opened up about being diagnosed with stiff-person syndrome, an infrequent, gradually worsening neurological disorder characterized by rigid muscles in the torso, arms, and legs. The National Institute of Neurological Disorders and Stroke explains that this syndrome also leads to hypersensitivity to noise, touch, and emotional stress, which can trigger muscle spasms.

Get the full lowdown on Dion's distressing health struggle.

The heartrending revelation came when Dion announced the deferral of her 2023 tour on December 8, 2022, attributing the decision to this devastating diagnosis.

In a heartfelt video posted on social media, Dion expressed the substantial impact of her condition on her everyday life. She said, "The spasms affect every aspect of my daily life, sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I'm used to." The emotional singer admitted the struggle, saying, "All I know is singing, it's what I've done all my life."

Nonetheless, Dion is optimistic about her recovery, "I have a great team of doctors working alongside me to help me get better," she confirmed to her fans. "I'm working with my sports medicine therapist every day to build back my strength and my ability to perform again."

Emphasizing her unwavering determination to recuperate, the Grammy winner stated, "I have hope I'm on the road to recovery. This is my focus, and I'm doing everything I can to recuperate."

A source revealed after the announcement that Dion's health had affected her weight, leaving her at a meager "96 pounds" in the months preceding her public disclosure.

Friends and family of the "The Power of Love" singer expressed concerns over her dedication to work, claiming that Dion often neglects her own health.

The source divulged in December, "She never did know when to stop." Moreover, they highlighted Dion's friends' advice for her to pace herself, emphasizing the growing concern about her wellbeing.

In a recent turn of events, the mother of three decided to call off her entire world tour, aiming to prioritize her health and avoid giving fans false promises.

In an Instagram post on May 26, Dion expressed her deep disappointment over the tour's cancellation but affirmed her commitment to recovering and returning to the stage. "I’m not giving up… and I can’t wait to see you again!' – Celine xx," the heartfelt message concluded.
