Chicago's First Lady Maggie Daley is back in the hospital suffering from flu-like symptoms.
Mrs. Daley was re-admitted to Northwestern Memorial Hospital Sunday night in stable condition, according to a Mayor's Press Office statement.
Mrs. Daley felt nauseous and experienced dehydration, according to the statement.
Doctors ran a series of tests before deciding to keep her for observation.
She was hospitalized for 10 days last month to get a metal rod in her leg replaced.
Doctors stressed this stay is not related to Mrs. Daley's cancer.
