US election: Donald Trump in excellent health, says his doctor

Republican nominee Donald Trump is in "excellent physical health," according to a letter from his doctor.

Mr Trump released the letter following a recent physical examination by Dr Harold N Bornstein.

The 70-year-old is listed as 6 foot 3 inches (1.9 metres) and weighs 236 pounds (107 kilos).

The letter comes as his rival Hillary Clinton returns to the campaign trail after time off with pneumonia, appearing briefly to reporters.

Boarding a plane in White Plains, New York, she spoke to journalists as she heads to North Carolina to hold a rally, her first campaign event since the weekend.

Both candidates have faced public scrutiny over transparency about the state of their health.

"He takes a lipid lowering agent (rosuvastatin) and a low dose aspirin," the letter said. "He does not use tobacco products or alcohol."

His weight and height give him a body mass index of 29.5, according to US measurements, which is within the "overweight" range but close to the "obese" mark at 30.0.

Mr Trump discussed his health with talk-show host Dr Mehmet Oz in a taped interview, which is set to air on Thursday.
