The White House said Thursday it is looking into whether President Trump plans to get a physical, and whether he'll publicly report the findings, as some predecessors in the Oval Office have done.

The review certifies from a physician whether the president is "fit for duty" and includes information about medical history and past tests, as well as information about new testing like a colonoscope. A 2010 exam for former President Barack Obama concluded that he was "fit for duty" and noted that he was using nicotine replacement therapy, which helps curb the urge to smoke cigarettes.

An exam in 2001 for former President George W. Bush also concluded he was "fit for duty" and included information about his medical injuries in the past, some of which were sports-related.

White House press secretary Sarah Sanders said she didn't know what Trump's plans were for reporting his health outcomes, but said she would check on it.

"I do know that I spent 12 days on the road with him in Asia, and despite the fact that he's a little bit older than me he had twice the energy that I did, and I'm the one that's sick now and he's still going, so I think he's in pretty good health," Sanders said.

Former presidents have gone to the Walter Reed National Military Medical Center in Washington, D.C., or National Naval Medical Center in Bethesda, Md., to be examined by a doctor. The two medical centers were combined in 2011 at the Bethesda location and took the name Walter Reed as part of the military's Base Realignment and Closure.

The topic of Trump's health and that of his former opponent, Hillary Clinton, featured prominently during the 2016 campaign for the Oval Office.

Questions about the health of Clinton, who was 69 at the time, surfaced when she stumbled following a 9/11 memorial event in New York, and questions about Trump, who was 70 at the time, emerged as he regularly shared his penchant for fast food on social media.

Dr. Harold Bornstein, Trump's family doctor for more than three decades, wrote a letter during the campaign certifying his health, saying that he "unequivocally" would be "the healthiest individual ever elected to the presidency."

Trump made his health records public by releasing a one-page report on the "Dr. Oz" show. The one-page letter from Bornstein, dated Sept. 13, 2016, said that Trump had "the stamina to endure — uninterrupted — the rigors of a punishing and unprecedented presidential campaign and, more importantly, the singularly demanding job of President of the United States."

The letter revealed that Trump weighed 236 pounds, which classifies him under the body mass index as just shy of obese. It also revealed that his blood pressure was normal and that he takes a statin for high cholesterol.

On Thursday, MSNBC host Joe Scarborough said that people close to Trump say he has early signs of dementia. Trump's father died of Alzheimer's disease, which is a type of dementia.
