The clot was discovered in a follow-up exam related to her concussion
Clinton is expected to remain hospitalized for at least the next 48 hours
She was scheduled to return to work this week after recovering from the concussion
Secretary of State Hillary Clinton was hospitalized Sunday after doctors discovered a blood clot during a follow-up exam related to a concussion she suffered this month, her spokesman said.
She is expected to remain at New York Presbyterian Hospital for the next 48 hours so doctors can monitor her condition and treat her with anti-coagulants, said Philippe Reines, deputy assistant secretary of state.
“Her doctors will continue to assess her condition, including other issues associated with her concussion,” Reines said. “They will determine if any further action is required.”
Reines did not specify where the clot was discovered.
Clinton, 65, was suffering from a stomach virus earlier this month when she fainted because of dehydration, causing the concussion.
Clinton spent the holidays with her family last week after working from home.
She was scheduled to return to work at the State Department this week after being sidelined for the past three weeks. Her illness forced her to bow out of testifying December 20 before the House Foreign Affairs Committee on the deadly attack on the U.S. Consulate in Benghazi, Libya. Deputies Thomas Nides and Bill Burns appeared in her place.
Clinton, a one-time presidential candidate who is the source of constant speculation she might run again in 2016, plans to step down from the State Department once a replacement is confirmed by the Senate.
