(CNN) - Rep. Michele Bachmann responded Tuesday to a report that the presidential candidate frequently suffers from severe headaches that have at least three times landed her in the hospital.
At a campaign stop in South Carolina, Bachmann said she treats her migraines with medicine as needed and emphasized the rigorous pace of her campaign schedule since she entered the 2012 race.
"I'm prescribed medication that I take on occasion whenever symptoms arise and they keep my migraines under control, but I'd like to be abundantly clear, my ability to function effectively … will not affect my ability to serve as commander in chief," Bachmann said.
Campaign press secretary Alice Stewart addressed an earlier report Tuesday from the Daily Caller that said Bachmann "suffers from stress-induced medical episodes that she has characterized as severe headaches."
"Like millions of Americans, Congresswoman Bachmann suffers with migraines and they are under control when treated with medication," campaign press secretary Alice Stewart told CNN.
Former Bachmann staffers spoke anonymously to the Daily Caller regarding Bachmann's episodes and whether they could impact her bid for the White House. Some former Bachmann staffers have left the congresswoman's office on anything but good terms, and it's not clear if those speaking anonymously to the Daily Caller have an agenda in speaking out against her.
