Sudden dizziness and nausea

Dizziness and nausea are common symptoms in people's daily life. Usually when this situation occurs, it has a great impact on people at that time, and sometimes serious situations even lead to the inability to live a normal life. There are many people who suffer from sudden dizziness and nausea, which is often due to insufficient blood supply to the brain or a cold. In addition, patients with cervical spondylosis or some vertebral artery problems may also experience such symptoms. The following detailed explanation of these causes is hoped to help everyone find the right medicine for their condition.

Some dizziness is caused by low blood pressure, insufficient blood supply to the brain, and even fainting. For example, at the 1996 Atlanta Olympics, my country's famous shooting athlete Wang Yifu fainted on the field for this reason.

Many patients with cervical spondylosis have symptoms of vertigo, mainly manifested as dizziness, tinnitus, nausea, and even deafness, blurred vision, and unclear vision. The main symptoms are nausea and even vomiting, pale complexion, sweating all over, and sometimes being unable to walk and needing help. 80% of vertigo is related to dislocation of the cervical intervertebral joints. How does vertigo occur? I think that, except for congenital factors such as cranial nerve malformations or organic lesions caused by trauma, about 80% of vertigo is related to dislocation of the cervical intervertebral joints.

We know that the vertebral artery is an important "pipeline" in the human body. It passes through the cervical vertebrae to the brain and is responsible for blood supply to the brain. Any dislocation, hyperplasia or other problems in the cervical spine may damage or affect this blood supply "pipeline", thereby affecting blood supply to the brain. Vertigo is caused by the dislocation of the occipital-atlas and atlantoaxial intervertebral joints compressing the third segment of the vertebral artery, resulting in insufficient blood and oxygen supply to the basilar artery. At this time, the brainstem, cerebellum, diencephalon, and cerebrum are all hypoxic and ischemic, and the labyrinthine artery and internal auditory artery are also ischemic and hypoxic, causing nerve disorder in the ear and tinnitus and deafness; at the same time, compression of the superior cervical sympathetic nerves causes vascular spasm in the brain, which aggravates the cerebral ischemia, so symptoms such as dizziness occur.

Some people may experience dizziness and nausea when riding in a car or boat, but they will be fine as long as they stop riding. This situation is related to personal constitution. Everyone should pay attention to strengthening exercise to improve their physical fitness. Pregnant women generally experience dizziness and nausea after pregnancy. This usually occurs in the early stages of pregnancy and will improve in the middle and late stages of pregnancy. There is no need to worry too much about dizziness and nausea. It may also be caused by other diseases in the body. Cerebellar lesions can also cause dizziness and nausea, such as cerebellar hemorrhage or infarction, and unstable walking. Cervical spine problems can cause insufficient blood supply to the vertebral basilar artery, which is a common disease that causes dizziness and nausea.
