Taking aspirin fights inflammation by blocking an enzyme called cyclooxygenase. This obstructs the pathway for producing prostaglandins, which cause inflammation. This can immensely reduce the pain a person faces and can even cure the problem completely. Aspirin is found to cause blood clots to form in the major arteries of the heart and brain muscle. A doctor may prescribe aspirin to allow better blood circulation throughout the body. The benefits and harms of aspirin should be weighed before taking it. Taking aspirin can pose many more risks. These risks can be caused by family history, taking other medications, and medical history.
