Celine Dion has been dealing with serious health issues that have put her career on hold. Her health condition first made headlines in 2022, when Dion ended one of her tours early.

In a statement, the singer attributed the canceled tour dates to her suffering from severe muscle spasms. Later that year, Dion revealed that she had Stiff-Person Syndrome.

As per Johns Hopkins Medicine, the rare autoimmune disease stiffens the muscles and causes spasms. In Dion’s case, the condition has affected her ability to use her vocal cords.

“These spasms affect every aspect of my daily life, sometimes causing difficulties when I walk and not allowing me to use my vocal cords,” Dion explained in an Instagram video.

The singer went on to say that she was undergoing treatment. As per her sister Claudette, Dion is “listening to the top researchers in the field of this rare disease.”
