Aspirin is not recommended for patients without cardiovascular or cerebrovascular disease. Aspirin is an anti-platelet aggregation drug. For patients with definite coronary atherosclerosis, or ischemic cerebrovascular disease, as well as patients with peripheral arteriosclerosis occlusion, the use of aspirin can play a very good therapeutic role by anti-platelet aggregation and reducing thrombosis. Aspirin is a necessary drug, but for healthy people without the above-mentioned diseases, long-term use of aspirin is not only not beneficial, but also has drug side effects, such as long-term application of aspirin can lead to edema and erosion of the gastric mucosa, the formation of peptic ulcers, and even gastrointestinal bleeding. The incidence of this condition is not low, so normal people avoid taking aspirin.
