What Taking Aspirin Every Day Does to Your Body

This popular remedy can have serious side effects.

One widely practiced health ritual may be on its way out. For years, doctors have recommended that some people take low-dose daily aspirin to lower their risk of cardiovascular disease. But a panel of experts has drafted a recommendation that doctors should no longer prescribe low-dose daily aspirin to prevent a first heart attack or stroke, the New York Times reported on Tuesday. Here is what taking aspirin every day does to your body, according to that task force and previous research. Read on to find out more—and to ensure your health and the health of others, don't miss these Sure Signs You May Have Already Had COVID.


Aspirin May Cause Serious Bleeding

This is the reason why the expert panel (known as the U.S. Preventative Services Task Force) is backing away from the daily aspirin recommendation: Taking daily aspirin increases the risk of serious bleeding, including in the stomach, intestines, and brain, a risk that already increases with age. The experts have determined that the risk of bleeding caused by daily aspirin may be greater than its potential reward.

However: The panel's recommendations won't apply to people who are already taking daily aspirin or have already had a heart attack, the Times reported. If you're taking daily aspirin and are wondering if you should continue, it's a good idea to talk to your doctor before making any changes to your routine.


Aspirin May Not Prevent Colon Cancer

In 2016, the task force recommended that people take baby aspirin to reduce the risk of colorectal cancer. Now they plan to reverse that guidance. The panel cited data from a randomized controlled study called Aspirin in Reducing Events in the Elderly. In that study, researchers found that aspirin use was linked to an almost doubling of colorectal cancer deaths after about five years. (Other experts disagree, and say there is good evidence taking aspirin can prevent colorectal polyps from turning into cancer.)

Aspirin Can Reduce Inflammation

There's a reason why aspirin has been around since 1899 as the first over-the-counter painkiller: It's very effective in reducing pain and swelling. Specifically, aspirin works by inhibiting prostaglandins, the enzyme that serves as an on-off switch for aches and inflammation. Classically, it's been used for fevers and pain.


Aspirin Can Cause Stomach Ulcers

Aspirin is a strong drug, and it can damage the lining of the stomach, causing pain, ulcers, and bleeding. The risk increases in people who are older, have stomach ulcers, take blood thinners or drink alcohol.
