Trump echoed this explanation himself in a 2024 interview with Time Magazine, linking the bruising to “thousands of handshakes.”

However, experts note that hand bruising in older adults isn’t uncommon and can result from more than just physical interaction.

Expert Insight: Age-Related Skin Changes Could Be the Cause

Dr. Ola Otulana, a UK-based general practitioner, provided an outside medical perspective on the marks. Speaking to Economic Times, he suggested the bruising looked like a superficial contusion — likely caused by minor impact, pressure, or even medical procedures such as a blood draw.

“As skin becomes thinner with age, and blood vessels more fragile, bruising can occur more easily,” Dr. Otulana explained. “This doesn’t indicate a serious issue unless accompanied by other symptoms.”

He added that individuals on blood thinners, aspirin, or similar medications are more prone to such markings, and that in Trump’s case, there’s no immediate cause for concern.

Is He Wearing a Catheter? Viral Image Sparks New Theory

Adding fuel to the fire, a photograph from a recent UFC event showed Trump with what some interpreted as a visible outline down one pant leg — prompting speculation about whether he might be wearing a catheter.

One viral post speculated: “That’s not a crease. That’s tubing. Possibly a Foley catheter.” Others disagreed, insisting it was simply a sharply pressed trouser line and noting that Foley catheters are generally reserved for post-surgical use, not everyday wear.

At nearly 80 years old, Donald Trump is subject to the same natural aging process as anyone else. Wrinkled hands, bruising, and even occasional balance concerns are not necessarily signs of illness — and according to his doctors, he remains medically fit.
