Can cervical spondylosis cause constant yawning?

It could be a sign of an underlying condition; however, if such symptoms occur, it indicates that the situation is already quite serious, and medical treatment at a hospital should be sought as soon as possible. Yawning is actually a physiological response in the human body, primarily caused by lack of oxygen or cerebral ischemia and hypoxia. Cervical spondylosis can also lead to insufficient blood supply to the brain. This condition generally suggests that the vertebral artery may be somewhat narrowed, potentially resulting in inadequate oxygen and blood supply to the brain.
