May 27 (UPI) -- Former President George H.W. Bush was hospitalized on Sunday after experiencing low blood pressure and fatigue, a spokesman said.
Bush's spokesman, Jim McGrath, shared a tweet stating the 93-year-old Bush was taken to a hospital in Maine, where he is expected to remain for a few days for evaluation.
"The former president is awake and alert, and not in any discomfort," McGrath said.
Prior to being hospitalized, Bush joined fellow veterans at the Post 159 monthly pancake breakfast in Kennebunkport on Saturday for Memorial Day weekend.
"This weekend we remember, and thank, all who have given their lives for our great country," Bush wrote on Twitter.
Bush decided to appear at the breakfast after he learned members of his staff, including his former national security adviser Brent Scowcroft were planning to attend.
"It was very spur of the moment. It being Memorial Day, having a chance to spend some time with veterans seemed like the thing to do for him," McGrath told the Portland Press Herald.
Bush returned to his family compound in Maine last Monday, after he was was admitted to the intensive-care unit at Houston's Methodist Hospital for two weeks as he fought off a blood infection.
He was hospitalized for the infection a day after the funeral for his wife, former first lady Barbra Bush, who died at the age of 92 in April.
Bush, the oldest-living former president -- and longest-lived president in U.S. history -- has vascular parkinsonism, a form of Parkinson's disease.
