Concerns about the health of United States President Donald Trump have been raised by a medical professor who believes Trump’s recent instances of nodding off could be an indication of a possible illness. Dr. Jonathan Reiner expressed worry after observing Trump appearing to fall asleep at Arlington National Cemetery during Memorial Day, suggesting it could be a sign of chronic insomnia.

Dr. Reiner stated that Trump has exhibited severe daytime drowsiness, often falling asleep in various settings, including the Oval Office. He highlighted the potential risks associated with chronic insomnia, such as an increased risk of dementia and cognitive decline in older individuals.

Scheduled for a medical examination on Tuesday, Trump’s health will be under renewed public scrutiny as he undergoes annual preventative medical and dental check-ups at Walter Reed National Military Medical Center. This examination marks Trump’s fourth publicly disclosed medical check-up since starting his second term in office, coinciding with his efforts to showcase strength ahead of upcoming midterm elections.

Traditionally, presidential physicals have provided limited insights into the commander-in-chief’s health, with results filtered through the White House and subject to presidential approval. Trump, the oldest person ever elected as U.S. president, faces public skepticism regarding his mental acuity and physical fitness to effectively serve as president, as indicated by a recent poll.

Dr. Jeffrey Kuhlman, a former White House physician under multiple administrations, emphasized that advanced age is a primary concern for Trump’s physical health. A comprehensive physical examination for a president of Trump’s age would typically encompass thorough heart evaluations, cancer screenings, cognitive assessments, and basic health metrics like blood pressure and body measurements.
