Former US President George H.W. Bush has been admitted to a hospital here, where the 92-year- old leader is responding to treatment, his top aide said today.
Bush was admitted to Houston Methodist Hospital falling ill recently.
"He's there. He's fine and he's doing really well," Bush's chief of staff, Jean Becker was quoted as saying by Houston Chronicle newspaper.
She said the doctors have a couple of theories about Bush's condition, but he is responding to treatment.
Becker did not specify the reason why Bush was hospitalised.
Bush, who lives in Houston, Texas, is expected to be discharged in the next couple of days, the report said.
Bush served as America's 41st president from 1989 to 1993.
As is the case with most people his age, Bush has had his share of health issues in recent years.
