Should I take an aspirin every day?

This is a complicated question. I think what’s difficult for many people to understand is that there’s no doubt that if you take a low-dose aspirin every day, you’ll reduce your risk of a heart attack and stroke. This fact is agreed upon by a majority of the medical community. But aspirin does have drawbacks.

Since it helps to stop blood from clotting, it increases the risk of making people bleed more easily — and research shows this risk increases with age. By this, I mean that you may get more nosebleeds or even little cuts could bleed more, but it can also increase the risk of internal bleeding in the brain or stomach, as well as the risk of developing a stomach ulcer.

So, before you decide whether or not to take a daily aspirin, you need to have a discussion with your health care provider. The answer you get will depend on factors such as your history of heart disease, your risk of heart attacks and strokes, and your age and overall health.

Your doctor may suggest you take a daily, low-dose (most commonly 81 mg) aspirin for two reasons. The first is for something we call “primary prevention.” If you’re included in this category, it means there are no heart issues in your medical history. You’ve never had a heart attack, stroke, or blocked arteries in any areas of your body; nor have you had coronary bypass surgery or coronary angioplasty with stent placement. If you’re in this category, your doctor will weigh the risks against the benefits of taking a daily aspirin.

There is debate over whether folks in this group who have never taken a daily aspirin and are over age 60 should begin taking one. The U.S. Preventive Services Task Force — an independent group of experts that issues evidence-based recommendations — says adults 60 and older should not start taking aspirin to lower their risk of a first heart attack or stroke. The guidance, issued in 2022, is based on research that suggests the harms of doing so — an increased risk for bleeding in the stomach, intestines and brain — can outweigh the benefits.

If you fit in the category of “secondary prevention,” it means that you’ve already had a heart attack or stroke, or you have underlying heart or vascular disease or diabetes. In these cases, it’s likely the upside of taking aspirin outweighs the downside.

A 2024 study, published in the Journal of the American Heart Association, which included more than 15,000 participants, found that taking a daily aspirin if you have heart disease, regardless of your age, is beneficial and overrides its risks. That said, you still need to speak with your doctor in case you have other complications, such as an allergy to aspirin, a bleeding or clotting disorder, or a history of gastrointestinal bleeding.

I admit that figuring out whether you should take a daily dose of aspirin can be tricky. A couple of years ago, media coverage warned people over 60 with no previous heart issues that if they were taking a daily aspirin, they were unnecessarily putting themselves in danger of bleeding. Well, my mother, who was then in her late 80s, heard that news and, without consulting me or any other physician, stopped taking her daily dose of aspirin.

She had been taking one every day for decades, and during that time, she never had a stroke, heart attack, stent, or bypass procedure. She had normal cholesterol, but she had prediabetes and high blood pressure. My mom also has a family history of heart disease. Within three months of not taking aspirin, she had a disabling stroke.

My mother’s story is a good lesson in why it’s so important to speak with your doctor before either starting or stopping an aspirin regimen. If she had asked me or her doctor whether she should stop taking a daily aspirin, we both would have said, “You have high blood pressure, and you’re prediabetic.” While we could do some additional imaging on on her arteries, we still would have said, “You know what? Based on what we now know about you, I would like you to continue to take aspirin.”

But I want to be clear: a daily aspirin isn’t for everyone, and it’s not a magic pill that guarantees heart health. You also want to lead a healthy lifestyle. Eat a diet rich in fiber, fresh fruits and vegetables and avoid processed foods, be physically active, limit alcohol and don’t smoke, tame your stress and watch your weight, as well as have your blood sugar level checked. When it comes to taking care of our hearts, let’s not miss a beat.
