What is Dizziness?

Dizziness is a common symptom that people describe in different ways: a feeling of spinning, unsteadiness, or lightheadedness. It is often temporary and not serious, especially when caused by rapid standing, dehydration, or fatigue.

Sometimes dizziness is related to the inner ear, which is responsible for balance, and sometimes it is caused by other conditions that require medical evaluation.

Possible causes

  • Low blood pressure when standing up suddenly.
  • Dehydration, skipped meals, or low blood sugar.
  • Inner ear problems and balance disorders.
  • Fatigue, lack of sleep, and anxiety.
  • Certain medications as a side effect.

These are common general causes; determining the exact cause requires medical evaluation.

When to see a doctor

Consult your doctor if:

  • Dizziness recurs or persists without an obvious cause.
  • It affects your balance or is accompanied by ringing in the ears or hearing loss.

Seek emergency care immediately if you experience sudden dizziness with difficulty speaking or seeing, weakness or numbness in the face or limbs, severe chest pain, or fainting.
