Cannon, 31, was in Aspen, Colo. vacationing when he was admitted to the hospital, but has now moved to a Los Angeles hospital, according to his Twitter.

His wife, Mariah Carey posted a picture of them on her Web site from Jan. 4th. Her post reads, “please keep Nick in your thoughts because this is very painful. They tried to kick me out of the hospital but here I am pon de bed with Mr. C.”

Cannon remained tightlipped on what provoked the hospitalization. But chronic kidney disease is higher among African Americans with diabetes and high blood pressure are the first and second leading causes of kidney failure, according to the National Kidney Foundation.

Kidney disease occurs, according the National Institutes of Health, when the kidneys can’t properly remove waste and extra water from the blood. African Americans are affected by kidney disease at rates up to four times higher than in European Americans.
