Dr. Ronny Jackson says in a statement released by the White House that Trump's physical Friday "went exceptionally well".
In a brief statement, Jackson said, "The President's physical exam today at Walter Reed National Military Medical Center went exceptionally well".
The White House announced earlier this week that Jackson would take the unusual step of answering questions about the president's exam during the daily briefing next Tuesday.
After a week of questions about Trump's mental fitness spurred by a damaging new book, the White House said the doctor's exam would not include any psychiatric tests.
There is a long history of the White House picking and choosing what to reveal about the Commander-in-Chief's health, said Barbara Perry, director of presidential studies at the University of Virginia's Miller Center.
A routine annual affair for every U.S. president, Trump's medical checkup is being widely reported and has drawn media attention in view of his political opponents raising questions about his health.
Sanders has brushed aside concerns expressed by reporters about the president's health as "ridiculous".
GETTY TURNING POINT Donald Trump's first physical exam could be a major event
Usually going for a medical check-up isn't a big deal, unless of course you're the President of the United States of America.
Mr Bornstein had previously written about Mr Trump's health in glowing terms, stating in 2015 he would be "the healthiest individual ever elected to the presidency". Past presidents have received a "fit to serve as president" stamp of approval following the exam. He uses a cart when he plays golf.
Trump does not smoke, and he does not consume alcohol.
What precisely will be disclosed about the President's health isn't yet clear.
Trump, who is the oldest president to take office, in public appearances has slurred words and grasped a drinking glass with both hands. Because the health information is considered private under federal law, the President himself must sign off on its release.
Trump's physical will be among the most closely scrutinized of any president in decades, perhaps since Ronald Reagan, who was wounded in a 1981 assassination attempt and also suffered from Alzheimer's disease while still in office, according to his youngest son, Ron Reagan.

The coalition, which says it takes all precautions to minimize civilian casualties, could not be reached for comment. The media arm of the rebels, known as the Houthis, said Thursday's projectile was a Qaher 2-M ballistic missile.
