Secretary of State Hillary Clinton was hopsitalized on Sunday at Manhattan’s New York Presbyterian-Hospital with a blood clot. The clot was discovered while Clinton was undergoing a follow-up for a concussion she suffered a few weeks ago and is a result of the accident, according to a statement from the State Department.

Dr. Roshini Raj of the New York University Medical Center told the TODAY show that the clot is not likely directly from the concussion, but from extensive bedrest during the recovery process.

While it is unknown where the clot is, the fact that she is being treated with anticoagulates means the clot is probably not in her brain, Dr. Harlan Krumholz of Yale University Medical School told the Wall Street Journal.

But Clinton could be at risk of deep vein thrombosis, in which clots form in the veins of the legs. Under such circumstance the clots can travel to the lungs and cause a pulmonary embolism, a life-threatening lung condition.

Clinton's recent troubles (she also fell ill with a stomach virus in early December) have raised speculation regarding not only her health, but her motives. She failed to appear before a congressional committee regarding Sept. 11 attacks on U.S. diplomats, however Clinton says she will testify once she is physically able, the Los Angeles Times reports.

Clinton will soon leave her post as Secretary of State and likely be succeeded by President Barack Obama's nominee John Kerry. Clinton's health problems could impact her decision as whether to run for President in 2016.
