Houston ? Former first lady Barbara Bush was hospitalized Saturday in Houston to undergo routine tests but doctors don’t suspect anything serious, a family spokeswoman said.

Bush, 84, was being treated at Methodist Hospital and should be released in a day or two, spokeswoman Jean Becker said late Saturday.

“She hasn’t been feeling well for about a week, and the doctors thought she should come in and undergo a battery of tests,” Becker said. “It’s not serious. She just hasn’t been feeling herself and they’re just trying to figure out why.”
