First, the first thing that comes to mind is blood pressure. Because after entering middle age, you have certain arteriosclerosis (which happens to everyone, but the hardening speed is different), especially some people who smoke and drink all the year round. At this time, your blood pressure will be unstable. Have you ever measured your blood pressure when you are dizzy? Have you ever taken your blood pressure when you are not dizzy? Is it high? What's your vomiting like? Is it that kind of jet vomiting? If so, you should be careful. It may be intracranial hypertension caused by hypertension. It is necessary to immediately reduce the intracranial pressure to prevent cerebrovascular accidents. If your blood pressure is not high, it is still a little low, and the above-mentioned dizziness, nausea and vomiting will also occur. It is mainly considered that it is caused by insufficient blood supply to the brain. Moreover, if your blood lipid is higher, the blood will be sticky and the blood flow rate will slow down, which will aggravate the dizziness.
Cervical spondylosis. Have you ever had your own cervical examination? Have you taken an anteroposterior cervical radiograph? If yes, is there any problem? Because the incidence of cervical spondylosis is too high now, some people think they don't have the disease because they don't have numbness in their hands, neck pain and other symptoms of cervical spondylosis. However, they found cervical spondylosis when they did a health check-up, and it is quite serious. In addition to cervical discomfort, many cervical spondylosis will have symptoms of dizziness and nausea. It is because the stenosis of intervertebral space oppresses blood vessels and nerves, resulting in insufficient blood supply to the brain.
Simple cerebral blood supply deficiency. Only after all the tests are normal can we consider simple cerebral blood supply deficiency.
Fourth, there is another disease. Most of the patients are elderly people. But in recent two years, the disease has become younger. It is a common lacunar cerebral infarction in clinic. After a small blood vessel is blocked locally, it does not affect the activities of limbs, nor does it have any symptoms of cerebrovascular disease. Only dizziness and nausea will occur, and because the focus is small, it can only be found by strengthening CT or magnetic vibration.
In short, if you want to know the cause, you should go to the hospital for a comprehensive examination and try to get early treatment.
