Cervical Spondylosis And Its Surprising Link To Dizziness And Nausea

Many people are unaware that cervical spondylosis, a common condition associated with wear and tear on the neck vertebrae, can cause symptoms such as dizziness and nausea. This occurs primarily due to instability, misalignment, or bone spurs in the cervical spine, which can cause the transverse foramina — small openings in the vertebrae — to become curved or constricted.

Understanding The Anatomy Behind Cervical Vertigo

Within the cervical spine are seven vertebrae, each containing a transverse foramen. These foramina form a continuous channel through which the vertebral arteries pass, eventually supplying blood to the brainstem and cerebellum. When these openings become distorted due to degenerative changes, the vertebral arteries may become compressed or kinked, leading to reduced blood flow to critical areas of the brain responsible for balance and spatial orientation.

The Role Of Blood Supply In Maintaining Balance

In addition to the vertebral arteries, the brain receives blood from the internal carotid arteries, which supply the cerebrum. Together, these systems ensure that all regions of the brain receive adequate oxygen and nutrients. However, when vertebral artery flow is compromised due to cervical abnormalities, it can disrupt the function of the vestibular system, resulting in episodes of dizziness, vertigo, and even nausea.

This condition, sometimes referred to as cervical vertigo, is often overlooked but can significantly impact a person's quality of life. Recognizing the link between neck health and neurological symptoms is essential for proper diagnosis and treatment.
