Doctors are expected to make a determination shortly about whether any further action is required, Reines said, adding that doctors will continue to assess Clinton's condition, "including other issues associated with her concussion." Clinton was expected to return to work next week, almost three weeks after being sidelined by the concussion. The secretary of state had been recuperating at home. Aides and doctors say Clinton contracted a stomach virus in early December and became dehydrated, then fainted, fell and hit her head. She was diagnosed with a concussion on Dec. 13 and hasn't been seen in public since.
Clinton's illness led her to cancel an overseas trip and scheduled testimony before Congress about the attack on the U.S. Consulate in Libya. The former first lady and senator, who had always planned to step down as America's top diplomat in January, is known for her grueling travel schedule. She is the most traveled secretary of state in history, having visited 112 countries while in the job.
The secretary of state's husband, former President Bill Clinton, suffered from heart disease and underwent successful quadruple bypass surgery in 2004 at Columbia Presbyterian Medical Center in New York City. In 2010, Bill Clinton had two coronary stents implanted in his heart after being hospitalized for chest pain.
