Insufficient blood supply to the brain may be caused by vertebral artery-type cervical spondylosis, cerebral atherosclerosis, insufficient pumping of blood from the heart, and chronic hypoxia in the brain.
1. Vertebral artery-type cervical spondylosis: herniated cervical intervertebral discs compress the vertebral arteries, affecting the insufficient blood supply to the brain and causing insufficient blood supply to the brain.
2. Cerebral atherosclerosis: due to the formation of cerebral atherosclerosis plaque, resulting in narrowing of cerebral blood vessels, affecting the blood supply to the brain, resulting in insufficient blood supply to the brain.
3. Insufficient pumping of blood by heart: such as chronic heart failure, the pumping ability of heart can be weakened and cardiac output can be reduced, resulting in insufficient blood flow to the brain, causing insufficient blood supply to the brain.
4. Chronic hypoxia in the brain: In chronic obstructive pulmonary disease, the partial pressure of oxygen in the blood is low, which affects the oxygen supply to the brain and leads to insufficient blood supply to the brain.
If you have symptoms of insufficient blood supply to the brain, you should consult a doctor in time to find out the cause of the disease and treat the cause.
