Aspirin Aspirin may not be healthy for the DIGESTIVE TRACT but can sometimes also cause serious bleeding in the upper GASTROINTESTINAL tract. A doctor's office manager said the risk of bleeding is directly related to aspirin. He also said that ¼ cup aspirin is good for a day (about the same amount of aspirin as a child's). Another thing he said was that if you take aspirin for arthritis it could cause severe bleeding. Late last month, in a journal called Lancet, Lancet compared aspirin use among 550 people hospitalized with severe stomach bleeding or DUODENUM with the aspirin-taking practices of 1,202 non-hospitalized people from the same communities . An aspirin-induced ULCER or gastric inflammation of the stomach lining is the cause of such bleeding which typically causes vomiting of blood. In virtually everyone who takes aspirin, aspirin can cause MICRO BLEEDING. More serious bleeding is rare, but poses a life-threatening risk, especially if the person has other medical problems or has lost a lot of blood quickly. In one survey 19 people out of 100,000 had a serious hemorrhage. It is precisely the power of aspirin that makes it effective against heart attacks and strokes caused by clots. I think you shouldn't take aspirin to prevent heart attacks, strokes or etc... for a reason and that reason is that it could cause another danger for you while you're trying to prevent it from happening to you.
