Long-term use of aspirin has been a topic of interest for many individuals, particularly those with heart conditions. According to the Mayo Clinic, long-term aspirin use can have both benefits and potential side effects [2].

Aspirin works by thinning the blood, which can help prevent blood clots from forming. This is particularly beneficial for individuals who have had a heart attack or stroke, as it can help prevent further cardiovascular events [2]. However, long-term use of aspirin can also lead to several potential side effects.

One of the most common side effects of long-term aspirin use is gastrointestinal bleeding [2]. This is because aspirin can irritate the lining of the stomach and intestines, leading to bleeding. In some cases, this bleeding can be severe and require medical attention.

Another potential side effect of long-term aspirin use is an increased risk of hemorrhagic stroke [2]. While aspirin can help prevent ischemic strokes (which are caused by blood clots), it can also increase the risk of hemorrhagic strokes (which are caused by bleeding in the brain). This is because aspirin thins the blood, making it more difficult for the body to form clots and stop bleeding.

Additionally, long-term aspirin use can lead to an increased risk of kidney damage [1][3]. This is because aspirin can cause the kidneys to produce more urine, which can lead to a loss of important nutrients and electrolytes. Over time, this can lead to kidney damage.

Finally, long-term aspirin use can also lead to an increased risk of allergic reactions [1]. These reactions can range from mild (such as hives or a rash) to severe (such as anaphylaxis).

In summary, while long-term aspirin use can be beneficial for some individuals, it can also lead to several potential side effects. These include gastrointestinal bleeding, an increased risk of hemorrhagic stroke, kidney damage, and allergic reactions. It is important for individuals who are considering long-term aspirin use to speak with their healthcare provider to determine whether the benefits outweigh the risks.
