The incidence of cerebral aneurysm hemorrhage in China is about 1 in 10,000, but about 5% of the population has an aneurysm itself, the difference only lies in the onset or not. Therefore, early examination and hospital treatment recommendations are very important. So what factors lead to a ruptured aneurysm? As we can see from the data, about 5% of people have aneurysms in their brains, while the prevalence of ruptured brain aneurysms is 1 in 10,000, so it proves that there are different factors that cause bleeding brain aneurysms. There are more factors that can cause aneurysm rupture. First, it is the condition of the individual’s own aneurysm that can affect its risk, such as a large aneurysm. Secondly, people at risk need to pay more attention, for example, high blood pressure is likely to cause brain aneurysm bleeding, so people at risk should pay more attention to controlling blood pressure. A sudden increase in blood pressure caused by mental tension, emotional excitement, exertion, violent head swing, bending over, getting up sharply, drinking alcohol, straining to defecate, lifting heavy objects, etc., can easily trigger rupture and bleeding and pose a threat to the patient’s life. Since about 30% of patients with cerebral hemorrhage caused by ruptured aneurysm may die before they can be treated, which is what many people think of as sudden death, great care should be taken during prevention and preliminary examination. It is also important to be cautious when treating the hemorrhage because there is a possibility of secondary bleeding after the tumor ruptures, so you should try to choose hospitals with better conditions and higher medical and nursing teams to get the best treatment. At the same time, it is better to maintain a healthier lifestyle, try to control the blood pressure as much as possible, and have timely checkups and treatments to prevent problems before they occur.
