Donald Trump made an unusually candid admission about his health routine during a campaign rally in Ohio.

The 80-year-old president said he takes a full-strength aspirin every day even though his doctors have encouraged him to use a smaller dose.

His reason, he explained, is partly psychological.

“I take an aspirin a day,” Trump told supporters in Vandalia.

“I don’t know if it works, but psychologically I need it.”

Trump then launched into an extended explanation of the habit he says he has maintained for decades.

“It thins the hell out of your blood, I guess,” he said.

“I don’t know if it works or not, but I’ve been doing it for a long time. And here I am making speeches.”

He said he prefers Bayer aspirin and takes the “big one” rather than the smaller low-dose version his doctors have recommended.

Trump appeared to stumble over the exact dosage.

“They want me to go down to the 80,” he said, apparently referring to the commonly used 81-milligram low-dose tablet.

“I take the 386. I don’t know what the hell it is. It’s a monster.”

Standard full-strength aspirin tablets are generally 325 milligrams, and Trump has previously said that 325 mg is the dose he takes.

His comment about “386” therefore appears to have been a verbal mistake rather than a description of a standard aspirin dose.

Trump said his doctors have questioned why he continues taking the larger tablet.

“They said, ‘Sir, you don’t need that!’” he recalled.

His response, according to Trump:

“I’ve been doing okay for 35 years. Leave me alone.”

He then joked that switching to the smaller tablet would make him nervous.

If something bad happened afterward, he said, he would blame the doctor who persuaded him to change the routine.

The remarks should not be interpreted as Trump saying aspirin treats a psychological condition.

He was describing the reassurance he gets from continuing a long-established habit.

Trump has previously described himself as somewhat superstitious about his aspirin routine and has said he is reluctant to change something he believes has worked for him for decades.

That distinction matters because aspirin is not being used here as a psychiatric medication.

It is an antiplatelet drug that reduces the ability of platelets to clump together and form blood clots.

For certain patients, that effect can be lifesaving.

Aspirin is commonly prescribed after heart attacks, some strokes, coronary stent procedures and bypass surgery because it can reduce the risk of future clot-related events.

But the equation is different for people taking aspirin purely to prevent a first heart attack or stroke.

Modern medical guidelines have become considerably more cautious about routine daily aspirin use in older adults because the medication can increase the risk of gastrointestinal bleeding, intracranial bleeding and hemorrhagic stroke.

The U.S. Preventive Services Task Force recommends against starting low-dose aspirin for primary cardiovascular prevention in adults aged 60 or older.

The American Heart Association similarly says routine aspirin use is generally not recommended for healthy adults over 70 who have not previously suffered cardiovascular disease.

Those recommendations do not establish what Trump personally should take.

That decision depends on his medical history and why his physicians prescribed or continued the medication.

Trump himself has acknowledged one obvious side effect.

Bruising.

He has previously said the larger aspirin dose makes him bruise easily, particularly on his hands.

The White House has attributed the discoloration periodically visible on Trump’s hands to a combination of aspirin use and frequent handshaking.

Trump has also acknowledged using makeup to conceal some of the marks.

The president’s health has received increasing attention during his second term.

The White House has previously disclosed that Trump has chronic venous insufficiency, a common circulatory condition that can cause swelling in the legs and ankles.

That diagnosis is separate from his aspirin use.

There is no basis to connect every visible bruise, episode of swelling or public appearance to a single underlying medical problem without clinical evidence.

The Ohio remarks nevertheless offered a rare window into how Trump himself thinks about one part of his health routine.

And his explanation was less scientific than personal.

He repeatedly emphasized how long he had been taking the drug.

The logic was essentially that he had done it for decades and remained reluctant to alter a routine he associated with staying healthy.

That mindset is exactly what he appeared to mean when he said he needed the aspirin “psychologically.”

The comment came during a Saturday campaign rally in Vandalia, where Trump was campaigning for Ohio Republicans including Sen. Jon Husted and gubernatorial candidate Vivek Ramaswamy ahead of the Nov. 3 midterms.

The aspirin discussion lasted only a small portion of a much longer political speech.

But it quickly drew attention because presidents rarely discuss medication habits so casually — particularly when acknowledging that their own doctors would prefer a different dose.

Trump presented the disagreement almost as a matter of instinct versus medical advice.

His doctors, by his telling, prefer the smaller tablet.

Trump prefers the larger one.

Not because he produced evidence that the higher dose works better.

But because he has taken it for decades and feels uneasy about changing.

“I don’t know if it works,” he told the crowd.

For Trump, apparently, that uncertainty has not been enough to break the habit.
