Donald Trump has repeatedly asserted that he’s in excellent health—claims backed by official medical evaluations—but recent observations and expert opinions are raising new questions.

In April, the White House released a medical report from Dr. Sean Barbabella, Trump’s physician, who assured the public that the former president is “fully fit” to serve. The report detailed that Trump stands 75 inches tall, weighs 224 pounds, and has normal results from scans of his eyes, ears, heart, and throat. It also noted he had cataract surgery, was taking several prescribed medications, and had recently undergone a colonoscopy that revealed a benign polyp and mild diverticulitis. Barbabella concluded that Trump was in “robust” physical and neurological health, crediting an active lifestyle for his well-being.

“President Trump exhibits excellent cognitive and physical health and is fully fit to execute the duties of the Commander-in-Chief and Head of State,” Dr. Barbabella wrote.
