Gary Coleman.
A Utah Valley Regional Medical Center spokeswoman says Coleman was admitted to the Provo facility on Wednesday but she couldn't release any other details.
Coleman lives in Santaquin, which is 55 miles (90km) south of Salt Lake City.
The 42-year-old actor is best known for his stint on TV's Diff'rent Strokes, which aired from 1978 to 1986.
In February, Coleman suffered a seizure on the set of The Insider.
A telephone message left for Coleman's Utah attorney was not immediately returned Thursday.
