MASON CITY, Iowa -- Teresa Heinz Kerry, the wife of Democratic presidential candidate John Kerry, was taken to a hospital here late Saturday after complaining of an upset stomach, a spokeswoman said.

She was taken to Mercy Medical Center-North Iowa by ambulance from the airport.

"As a precaution, Mrs. Heinz Kerry had a series of routine tests performed and was released," said Sarah Geggenheimar, a spokeswoman for Heinz Kerry. "She is feeling better and is traveling to her home in Pittsburgh tonight as planned."

Heinz Kerry had just finished a private meeting with a group of local Democrats to talk about health care.

"She was just fatigued I think. She said she felt a little dizzy at one point," said Steve Musson, a local restaurateur at whose home the gathering was held.

"She was only here a couple hours," Musson said. "She had a glass of water and didn't eat anything ... She seemed fine when she left here."

Kerry had been campaigning in Ohio, separately from his wife, when she became ill and drove in a motrocade to their Pittsburgh home early in the evening.
