We have already sorted it out mechanism of action of aspirin. It irreversibly blocks something in the stomach and platelets for several days. Maybe even for two weeks. Other NSAIDs don't do this. Due to this, aspirin turns off the natural protection of the stomach from damage and discourages platelets from gathering in a heap.
In the case of the stomach, this is unambiguously bad, and in the case of platelets, it is sometimes useful. Sometimes - because without the normal functioning of platelets, we risk getting bleeding from the same stomach or hemorrhage into the brain.
But on the other hand, if the risk of blood clots in the arteries of the heart or brain is higher than the risk of bleeding, then aspirin will be useful.
If you have a low risk of blood clots in your arteries, then aspirin will only hurt.
So many people do not want to take risks in anticipation of bleeding, but they want to insure themselves in terms of thrombus formation. Therefore, it is tempting to take aspirin once a week. There will be no type and cerebral hemorrhage, and thrombosis can be prevented.
No, brothers. It doesn't work that way. If you take aspirin occasionally, then you will not be protected from thrombosis, but you can get bleeding. That is, you will not get any benefit, but you will earn side effects for yourself.
Malicious scientists from medicine have been trying for decades to decide exactly how much aspirin will protect you from a stroke, but it will not often kill you by bleeding from the stomach.
It turns out that if you take aspirin once a day, you can reduce the dose to some extent. Therefore, pharmacies sell you all sorts of pills in which aspirin is less than 100 milligrams. These are the doses that have proven to be effective in preventing any disease, but on condition that you take them every day. If taken every other day, the benefits are much less, but the side effects remain. Are you offended? I don’t.
