There are three main causes of unsteadiness: 1) cranial, such as hypotension, hypoglycemia and intracranial related diseases, such as brain tumors, cerebral edema, cerebral hemorrhage, cerebral infarction, etc., which may lead to a decrease in brain cell function and unsteadiness, possibly due to vestibular neuritis, vagal effusion, otoliths, as well as hyperplasia and degeneration of the cervical spine, stimulating the sympathetic nerve or vertebral artery, or The condition of unsteadiness may occur due to a decline in cardiopulmonary function, which affects the blood supply and oxygenation of the brain. 2. Abnormalities in the nerve tissue, such as compression of the spinal cord after significant narrowing of the cervical spine, resulting in ischemia of the nerves in the spinal cord, or compression of the nerve roots in the lumbar spine, resulting in abnormal nerve root function, may also cause unsteadiness. 3. The muscles of the body can maintain the balance of the body, if the muscle tissue suffers from trauma or muscle atrophy and neurological muscle weakness, it may lead to unstable standing.
