The president's doctor said the CT scan was normal and that Obama's symptoms "are consistent with soft tissue inflammation related to acid reflux."
White House press secretary Josh Earnest said the President was not sedated, so no transfer of authority was necessary. However, Vice President Joe Biden and other senior White House staffers "were kept up to speed," Earnest said.
The doctor's visit was not on the White House schedule for Saturday and reporters hustled to join the president's motorcade to Water Reed in Bethesda, Maryland. The president left the hospital 28 minutes after arriving.
Dr. Ronny L. Jackson, Obama's physician, issued a statement:
"This morning, an ear, nose and throat specialist from Fort Belvoir Medical Center conducted a fiber optic exam, under my supervision, of the President's throat based on symptoms of sore throat over the past couple weeks. The exam revealed soft tissue swelling in the posterior throat and I, in consultation with the specialist, determined that further evaluation with a routine CT scan was prudent.
"The CT scan was conducted this afternoon purely as a matter of convenience for the President's schedule. The CT scan was normal. The President's symptoms are consistent with soft tissue inflammation related to acid reflux and will be treated accordingly."
CNN chief medical correspondent Sanjay Gupta said acid reflux usually can be easily treated.
Obama visited Jackson for his periodic checkup in May. Jackson described Obama's overall health as "excellent."
The checkup information, released in June, was the third medical report released by the White House during Obama's presidency, informs Report.
