Based on the information available, frequent aspirin use has been found to increase the risk of bleeding during surgery [1]. Aspirin is a common antiplatelet medication that works by preventing platelets in your blood from sticking together to form clots [2]. However, this effect also means that aspirin can increase the risk of bleeding, including during and after surgical procedures [1][2].

A study published in the Journal of the American Medical Association found that patients who took aspirin in the two weeks before surgery had a higher risk of bleeding complications than those who did not take aspirin [1]. The study concluded that "these results support the recommendation to discontinue aspirin before elective surgery" [1].

It is important to note that the increased bleeding risk associated with aspirin use is generally reversible and will decrease once the medication is stopped [2]. However, patients should always consult with their healthcare provider before stopping any medication, especially if they are scheduled for surgery [2].

In summary, frequent aspirin use can increase the risk of bleeding during surgery, and patients should discuss their medication regimen with their healthcare provider before undergoing surgical procedures.
