Barbara Bush hospitalized

Former first lady Barbara Bush was hospitalized Saturday morning after she complained she was "not feeling well," her spokeswoman said Sunday.

However, Bush, 84, is expected to be released from Methodist Hospital in Houston in about a day or two, doctors said this weekend.

According to Bush's chief of staff, the former first lady was not admitted for anything serious on Saturday. Rather, it was a precautionary measure, her top adviser said, noting Bush had kept up her public schedule in recent days despite not feeling "like herself."

According to reporters, former President George H.W. Bush traveled with her to the hospital.

The former first lady was most recently admitted to the hospital in 2009 for open-heart surgery, after doctors noted trouble with her aortic valve. Prior to that, she was treated in 2008 for a perforated ulcer.
