Checkup finds Biden 'vigorous'; Harris briefly in power

President Joe Biden remains healthy and vigorous and fit for duty, but is showing some signs of aging, his doctor said Friday after the oldest president in American history underwent his first routine physical in office and in a history-making moment briefly transferred power to Vice President Kamala Harris while he underwent a colonoscopy.

Harris, the first woman, first Black person and first person of South Asian descent to be vice president, was for one hour and 25 minutes acting president while Biden was under anesthesia.

Over more than five hours Friday at Walter Reed National Military Medical Center, the president underwent a battery of blood, physical, gastrointestinal, dental, vision and neurological examinations. Dr. Kevin O'Connor, who has been Biden's primary care physician since 2009, wrote in a six-page memo released by the White House that Biden, who turns 79 on Saturday, remains a healthy, vigorous, 78-year-old male, who is fit to successfully execute the duties of the Presidency.

O'Connor, however, revealed that he investigated Biden for increased instances of throat clearing during public remarks and a stiffening of his gait. O'Connor reported that Biden's coughing was the result of gastrointestinal reflux and that the stiffened gait was the result of a new diagnosis of mild peripheral neuropathy, spinal arthritis and compensation for a broken foot sustained a year ago.

Interest in Biden's health has been high ever since he declared his candidacy for the White House in 2019 and remains intense as speculation about a 2024 reelection bid swirls. The visit to the medical center in the Washington suburbs was for his first routine physical exam as president and his first since December 2019.

As part of the screening, Biden underwent an extremely detailed neurological exam that ruled out stroke, multiple sclerosis, Parkinson's and amyotrophic lateral sclerosis, but caught the neuropathy, which is nerve damage in the hands and feet. O'Connor said the most common cause of the condition is diabetes, but Biden is not diabetic. Biden, he said, would soon try custom orthotics to improve his gait.

During the course of Biden's colonoscopy a benign-appearing polyp of about 3 millimeters was identified and removed and would be studied over the coming week. O'Connor said Biden has never had colon cancer.

Biden's reported body mass index classified him as slightly overweight, but his cholesterol was under control. Biden, O'Connor said, is prescribed the anticoagulant Eliquis, the statin Crestor and the seasonal allergy spray Dymista, and regularly takes the over-the-counter allergy pill Allegra and the antacid Pepcid.

O'Connor reported that Biden does not use tobacco products or drink alcohol and that he exercises at least five days per week.

Press secretary Jen Psaki said he resumed his duties after speaking with Harris and White House chief of staff Ron Klain at approximately 11:35 a.m.

As Biden left the medical center in the afternoon, he said he was feeling Great!

Great physical and a great House of Representatives vote, he said, referring to the House passage of his roughly 2 trillion social and environmental agenda.

After arriving back at the White House, he said Nothing's changed with his health, joking, "We're in great shape, and I'm looking forward to celebrating my 58th birthday.

While serving as acting president Harris was working from her office in the West Wing, Psaki said. She later traveled to Ohio once Biden awoke from the procedure.

Biden was keenly aware of the history he was making when he selected Harris to be his running mate, Psaki said, adding that she made history every day in the job.

Today was certainly another chapter in that history I think that will be noted for women, young girls across the country," she added.

During Biden's last physical exam, doctors found the former vice president to be healthy, vigorous and fit to successfully execute the duties of the Presidency," according to a doctor's report at the time.

In that report, O'Connor said that since 2003, Biden has had episodes of atrial fibrillation, a type of irregular heartbeat that's potentially serious but treatable. At the time, O'Connor cited a list of tests that showed Biden's heart was functioning normally and his only needed care was a blood thinner to prevent the most worrisome risk, blood clots or stroke.

Biden had a brush with death in 1988, requiring surgery to repair two brain aneurysms, weak bulges in arteries, one of them leaking. Biden has never had a recurrence, his doctor said, citing a test in 2014 that examined his arteries.

Dr. Jeffrey Linder, chief of general internal medicine and geriatrics at Northwestern University's Feinberg School of Medicine, read the White House report and said it contained nothing that's particularly worrisome.

All in all, according to this report it seems like he's in pretty good shape, with very common age-related illness,'' including atrial fibrillation and stiff gait, Linder said.

While the cause of Biden's mild neuropathy is unknown, Linder said it is not an unusual problem and not a cause for concern unless it's bothersome for the president. He added that there is no reason to think the small polyp that was removed was cancerous, given Biden's previous medical history.
