"He did not undergo any procedures requiring sedation or anesthesia", Conley said.
Dr Conley was joined by 11 other specialists who put the 72-year-old through a battery of medical tests. Trump, however, has said that he walks a lot in the White House complex.
In January, Trump hosted the strapping athletes of America's champion college football team, the Clemson Tigers, with a mountain of hamburgers and pizzas. Press Secretary Sarah Sanders said in a statement that "while he spends much of his average day in scheduled meetings, events, and calls, there is time to allow for a more creative environment that has helped make him the most productive President in modern history". But the doctor named as its author later said Mr Trump had written the letter himself.More news: A Forced Decision: Why the US Withdrew From the INF Treaty
No further details on the president's health have been released yet. Nor has he been known to enter the White House gym for a workout.
Modern-day presidents have undergone regular exams to catch any potential problems but also to assure the public that they are fit for office, something Trump's doctor a year ago took to an extraordinary level. Conley conducted this year's examination on Mr. Trump, which took place "over the course of approximately four hours".
Jackson, who is still under investigation, will also travel and work closely with White House staff.
Last year, doctors checked the president's eyes; ears, nose and throat; heart; lungs; gastrointestinal tract; skin; and teeth.
Jackson later was nominated by Trump to run the Department of Veteran Affairs, but the admiral withdrew his name after allegations of misconduct surfaced, including accusations he improperly dispensed medication. At the first physical of his presidency, which took place a year ago, he was found to weigh 239lb (108kg) and have a cholesterol level that is slightly higher than recommended.
