US presidents regularly undergo physical examinations. It is not remarkable. However, the results of Donald Trump's recent medical check-up have sparked an online conspiracy theory - the girther movement.
According to the official medical report, released by the White House on 16 January, President Trump stands at 75 inches (6ft 3in; 1.9m) and weighs 239lb (17st 1lb; 108kg).
But the girther movement, propelled mainly by critics of the president, posits that Mr Trump is shorter and heavier than the report suggests.
This particular presidential physical has received increased interest after questions were raised over Mr Trump's mental health and supposed unhealthy diet.
