It did not say why he had been admitted and his aides declined to give further details.
Mahathir has had heart problems in the past, suffering several heart attacks and undergoing bypass surgery.
He has been one of Malaysia’s most dominant political figures in recent decades, serving twice as prime minister for a total of 24 years.
His first stint was from 1981 to 2003, then he made a comeback and returned as premier in 2018 at the age of 92 at the head of a reformist coalition.
But that administration collapsed in 2020 due to infighting.
