Former New York City Mayor Ed Koch has been hospitalized for treatment of anemia.
George Arzt, a spokesman for the Democratic ex-mayor, said Koch was admitted to New York Presbyterian Hospital on Tuesday morning and underwent a blood transfusion.
Koch is undergoing a battery of hospital tests and expects to be in the hospital until Friday. Arzt had said the 87-year-old Koch hoped to be out of the hospital on Wednesday. He said Koch felt weak over the weekend while staying with friends in North Carolina.
The 87-year-old Koch, however, has been keeping busy in the hospital. He has been fielding calls from New York politicians in Charlotte, N.C. The spokesman said that when one asked Koch how he was feeling, he replied, "Forget about that. Tell me about the platform."
Anemia is a condition in which the number of healthy red blood cells in the body declines. Symptoms include weakness and dizziness.
Koch served three terms as mayor from 1978 to 1989 and is credited with rescuing the city from bankruptcy. Last year, the Queensboro Bridge was named after him.
