Aspirin is a medication that is commonly used to relieve pain, reduce inflammation, and prevent blood clots. While it can be beneficial in some cases, taking higher doses of aspirin can increase the risk of several health problems.

One of the most significant risks of taking higher aspirin doses is gastrointestinal bleeding. Aspirin can irritate the lining of the stomach and intestines, which can lead to ulcers and bleeding. This risk is especially high in older adults and people who have a history of stomach ulcers or gastrointestinal bleeding [1].

Another potential risk of taking higher aspirin doses is an increased risk of stroke. While aspirin can help prevent blood clots, taking too much can actually increase the risk of bleeding in the brain, which can lead to a stroke [2].

Additionally, taking higher doses of aspirin has been linked to an increased risk of advanced cancer. A study called ASPREE found that older adults who took daily aspirin had a higher risk of developing advanced cancer than those who took a placebo [3].

It is important to note that aspirin can interact with other medications, including blood thinners, and can cause side effects such as ringing in the ears, nausea, and vomiting. As with any medication, it is important to talk to a healthcare provider before taking aspirin, especially at higher doses.
