Romney's most recent physical examination Aug. 9 revealed "a healthy appearing, energetic, strong physically fit male" who "appears younger than his age."
The GOP presidential nominee "totally abstains from drinking any alcoholic beverages and does not use any tobacco products or illicit drugs," his personal physician, Dr. Randall Gaz, wrote.
Romney "eats a high-fiber diet with abundant fruits and vegetables and minimizes intake of high-cholesterol foods and concentrated sweets," Gaz said.
The letter noted Romney is allergic to penicillin and takes Lipitor and low-dose aspirin on a daily basis. Gaz said Romney's resting, regular heart rate is in the 40s, which is "most likely related to his past intensive exercise with regular running."
Gaz said Romney has "shown the ability to be engaged in multiple, varied, simultaneous activities requiring complex mental, social, emotional and leadership skills."
"He is a vigorous man who takes excellent care of his personal physical health. He has reserves of strength, energy and stamina that provide him with the ability to meet unexpected demands. There are no physical impairments that should interfere with his rigorous and demanding political career as the next president of the United States," the letter concluded.
Running mate Paul Ryan's overall health also is excellent, Dr. Brian Monahan wrote.
Ryan has practiced "important preventive lifestyle choices to include regular vigorous aerobic and strength-building exercises, a heart-healthy diet, smoking abstinence and infrequent alcohol use," Monahan said.
Ryan occasionally makes use of an albuterol inhaler to treat airway hypersensitivity and has a history of a herniated disc, the letter indicated.
