Former Mayor Ed Koch hospitalized

Former Mayor Ed Koch was hospitalized Tuesday, suffering from anemia.

“He’s been looking weak recently,” George Arzt, his former press secretary, told The Post. “He isn’t eating like he used to.”

Koch, 87, checked into New York Presbyterian/Columbia Medical Center on the advice of a longtime physician friend.

He was expected to be released after treatment, perhaps as early as Wednesday.

Koch served as mayor for 12 years starting in 1978 and remains an influential political force.

Last year, his endorsement of Republican Bob Turner over Democrat David Weprin in a Brooklyn congressional race helped propel Turner to a stunning upset victory.

The former mayor underwent a quadruple bypass in 2009 after suffering a previous heart attack and stroke.

To celebrate the success of the operation, he later invited 20 of his doctors and their spouses to dinner at the Peter Luger steak house.
