Is Blood Pressure 61/102 Normal? Understanding the Cause of Dizziness

When assessing blood pressure, a normal range at rest is typically considered to be a systolic pressure between 90-140 mmHg and a diastolic pressure between 60-90 mmHg. A reading of 61/102 mmHg falls within this acceptable range, indicating that the blood pressure is not the likely cause of any dizziness being experienced. If dizziness is occurring despite normal readings, other underlying causes should be explored, such as insufficient cerebral blood flow, cervical spine issues, or inner ear disorders like benign paroxysmal positional vertigo (BPPV).

1. Cerebral Hypoperfusion (Reduced Blood Flow to the Brain)

Transient dizziness can occur due to temporary reductions in blood flow to the brain. Factors such as fatigue, lack of sleep, or sudden changes in posture can contribute to this condition. Additionally, individuals with risk factors like high cholesterol or regular tobacco use may be more prone to arterial hardening, which can lead to chronic cerebral hypoperfusion. Symptoms may include dizziness, fatigue, blurred vision, or even brief motor impairments, despite having normal blood pressure. Diagnostic tools such as a head CT scan or MRI can help identify any abnormalities in brain circulation.

2. Cervical Spondylosis or Vertebral Artery Compression

How Neck Issues Cause Dizziness

Vertebral artery insufficiency, often associated with cervical spondylosis or disc herniation, can compress the arteries that supply blood to the brainstem and cerebellum. This compression can disrupt the posterior circulation of the brain, resulting in symptoms like dizziness, nausea, fatigue, and tinnitus. These symptoms are often exacerbated by specific neck movements or prolonged postures. A cervical CT scan or MRI can provide detailed images of the spinal structures and help confirm the diagnosis.

3. Benign Paroxysmal Positional Vertigo (BPPV)

The Role of Inner Ear Dysfunction

BPPV is a common cause of vertigo and is often triggered by age-related degeneration of the inner ear structures or by head trauma. It causes sudden, intense episodes of dizziness often accompanied by nystagmus (involuntary eye movement), visual spinning, nausea, and vomiting. These symptoms are typically triggered by specific changes in head position, such as lying down or turning over in bed. Diagnostic tests may include vestibular function assessments, audiologic evaluations, and imaging studies like CT or MRI to rule out other conditions.
