Understanding dizziness and vertigo
Escrito por:Dizziness and vertigo are common sensations that can significantly disrupt daily life. While they are sometimes used interchangeably, dizziness and vertigo have distinct characteristics.
Dizziness is a feeling of unsteadiness or lightheadedness, while vertigo refers to the sensation that you or your surroundings are spinning or moving, even when still. Both symptoms can stem from various causes, often linked to the inner ear, neurological conditions, or even cardiovascular issues.
Causes of vertigo
Vertigo is frequently associated with disorders of the inner ear, particularly when the vestibular system—responsible for balance—is affected. One of the most common types is benign paroxysmal positional vertigo (BPPV), a condition where small calcium crystals in the inner ear become dislodged, leading to dizziness when changing head positions.
Ménière’s disease is another inner ear disorder that causes vertigo and is often accompanied by hearing loss, ringing in the ears (tinnitus), and pressure in the ear. Vestibular neuritis, an infection that inflames the inner ear, can also cause sudden, intense vertigo.
Causes of dizziness
Dizziness, on the other hand, can arise from dehydration, low blood pressure, anaemia, or even side effects of medication. Anxiety and stress are also potential triggers, as they can cause hyperventilation, which affects blood flow to the brain and may lead to dizziness.
In some cases, dizziness could signal an underlying neurological issue, such as a stroke or multiple sclerosis, making it essential to seek medical advice when symptoms are persistent or worsening.
Treatment
Treatment for dizziness and vertigo depends on the underlying cause. For BPPV, a physical therapy maneuver known as the Epley maneuver can help reposition the displaced crystals in the inner ear, often providing relief. Medications may be prescribed for conditions like Ménière’s disease to manage vertigo and reduce inner ear fluid buildup.
Vestibular rehabilitation therapy, a series of exercises to improve balance, is beneficial for some people experiencing chronic dizziness. In cases where vertigo and dizziness are linked to lifestyle factors, staying hydrated, managing stress, and maintaining a balanced diet can help reduce symptoms.
Addressing dizziness and vertigo can significantly improve quality of life. Consulting a healthcare provider is essential to identify the root cause and develop an effective treatment plan tailored to the individual’s needs.
