There are many causes of nervous dizziness, commonly including normal physiological phenomena such as endocrine abnormalities and sympathetic excitation, but also abnormal pathological factors such as cervical spondylosis, brain or cerebrovascular disease. When tension dizziness occurs, it is recommended that patients go to the hospital to identify the cause and then do the appropriate treatment. A normal physiological phenomenon 1, endocrine abnormalities: when in a state of tension, it will lead to abnormal secretion of hormones in the body, excessive secretion of adrenal hormones will cause an increase in heart rate and blood pressure, accelerated breathing, and even produce dizziness; 2, sympathetic excitation: when in a state of tension, it will cause sympathetic excitation, resulting in a significant increase in blood pressure, accelerated heart rate, and accelerated blood flow. This leads to an increase in blood flow and intracranial pressure in the brain, which can lead to the appearance of dizziness. Second, abnormal pathological factors 1, cervical spondylosis: such as suffering from cervical spondylosis, when tension will cause spasm of the neck muscles, if the surrounding osteophytes, will stimulate compression to the vertebral artery, affecting blood supply, resulting in dizziness symptoms; 2, brain or cerebrovascular disease: brain or cerebrovascular disease exists, when tension can make the brain and cerebrovascular stimulation, which may lead to spasm of the blood vessels, thus making the transport to The blood and oxygen to the brain, resulting in insufficient blood and oxygen supply to the brain and thus dizziness.
