The spokesman for former New York City Mayor Ed Koch says he's been re-admitted to the hospital two days after he was released.
Spokesman George Arzt says Koch went back to New York-Presbyterian/Columbia hospital on Monday. He says Koch's doctor wanted the 88-year-old to get more treatment for the fluid in his lungs, which is causing shortness of breath.
Doctors have told Koch to reduce his salt intake.
Koch also was hospitalized in December with a respiratory infection and in September with anemia.
