It's been a tough few weeks for Hillary Clinton.
The Secretary of State was hospitalized after doctors found a blood clot during an exam related to the concussion she suffered during a fall earlier this month.
"Her doctors will continue to assess her condition, including other issues associated with her concussion," Philippe Reines, deputy assistant secretary of state, said Sunday.
"They will determine if any further action is required."
She's being treated with anti-coagulants and is expected to be stay at New York Presbyterian Hospital for 48 hours so she can be monitored, CNN reports.
The 65-year-old, who has visited more than 110 countries in the past four years, suffered a concussion when she passed out and fell in her D.C. home.
Reports at the time said dehydration suffered after a trip the former first lady took to Europe was the cause of her fainting spell and thus the fall that concussed her.
Clinton was recently named one of Barbara Walters's 10 most-fascinating people of 2012 and plans to step down from her secretary post early next year.
President Barack Obama has named John Kerry her replacement.
