President Trump will undergo a physical early next year and release the results to the public, the White House said Thursday.

The review will certify from a physician whether the president is "fit for duty." Past physicals of former presidents have included information about medical history and past tests as well as information about any new testing, such as a colonoscopy. Trump will be evaluated at Walter Reed National Military Medical Center in Bethesda, Md., White House press secretary Sarah Sanders said during the press briefing.

"He does have a physical scheduled for the first part of next year, the full physical that most presidents go through," she said. "That will take place at Walter Reed, and those records will be released by the doctor following that taking place."

She did not specify when exactly the medical exam would take place.

Trump's health is in the spotlight because a panel on MSNBC's "Morning Joe" suggested Thursday that his mental health was diminishing because he gave a speech Wednesday in which he appeared to be slurring words toward the end. Last week, 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 form of dementia.

Social media users had their own theories about Trump's slurred speech, speculating that it was attributable to a set of false teeth.

Sanders called the questions about Trump's health "ridiculous."

“The president’s throat was dry, nothing more than that,” she told reporters.

Other aspects of Trump's health have often gained attention, such as his eating habits. A book by Corey Lewandowski, Trump's former campaign manager, detailed that when Trump was a candidate he used to regularly eat fast food. A standard dinner would be comprised of two Big Macs, two Filet-o-Fish and a chocolate milkshake from McDonalds. Lewandowski has since defended his former boss's diet, saying that he never ate the bread that came with his sandwiches.

Former presidents have gone to the Walter Reed National Military Medical Center in Washington, D.C., or National Naval Medical Center in Bethesda 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. Other presidents have undergone similar evaluations at the start of their term.

Trump's health also was scrutinized during the presidential campaign because he used to post photos of himself with fast food. 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." In a second letter dated Sept. 13, 2016, Bornstein wrote 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.
