Dizziness may be caused by cervical spondylosis, otolithiasis, cerebral atherosclerosis and other diseases.
1. Cervical spondylosis: the vertebral artery is an important channel for blood to enter the brain, and people suffering from cervical spondylosis may tilt their heads backward, which pressurizes the vertebral artery and leads to narrowing of the vertebral artery, resulting in insufficient blood supply to the brain, and then dizziness occurs.
2. Otolithiasis: It is a common peripheral vestibular disease, also known as benign paroxysmal positional vertigo. When the patient’s head is tilted back, it is easy to make the otoliths fall off, which results in strong rotational vertigo and is accompanied by nystagmus, nausea, vomiting and other symptoms.
3. Cerebral atherosclerosis: lipids and necrotic tissues gather in the cerebral arteries to form atherosclerotic plaques, thus affecting the blood supply to the brain, and when the patient’s head is tilted back, it is easy to aggravate the cerebral ischemia, and dizziness occurs.
In addition, there are other reasons that can cause dizziness when tilting the head back, if accompanied by other discomforts, it is recommended to go to the hospital in a timely manner to find out the cause of the disease and receive treatment as soon as possible.
