Bing, 68, was resting comfortably at Detroit's Henry Ford Hospital, the statement released by the city said.
"He is expected to remain in the hospital for five to seven days and undergo a full recovery," Dr. Scott Dulchavsky, chairman of the hospital's surgery department, said in the statement. "The mayor will return to normal activities within three weeks. However, he can resume limited administrative duties as early as tomorrow. I expect a faster than normal recovery due to Mayor Bing's spectacular physical health. He is in very good spirits."
Mayoral spokesman Robert Warfield told the Detroit Free Press Bing designated Chief of Staff Kirk Lewis as deputy mayor and Lewis will act as mayor until Bing can resume his normal activities.
Left unclear was whether Lewis would take Bing's place in negotiations expected to take place between the city and Gov. Rick Snyder over whether Detroit accepts a consent agreement for state oversight of the city's finances.
The mayor was hospitalized Thursday after feeling discomfort following a dental visit. The next day it was announced he had been diagnosed with an inflammation of the intestine.
