What is Dizziness?
Dizziness is a common symptom with many possible causes, ranging from relatively minor issues like dehydration or standing up too quickly, to inner ear problems affecting balance, to, less commonly, heart or neurological conditions. It can feel like lightheadedness, a spinning sensation (vertigo), or unsteadiness.
Most dizziness is not serious and improves with simple measures or resolves on its own, but understanding the specific pattern — what triggers it, how long it lasts, and any accompanying symptoms — helps identify when further assessment is needed.

Clinical context
The pattern of dizziness gives useful clues
Brief dizziness when standing up quickly is usually harmless, while a spinning sensation triggered by head movement often points to an inner ear cause — describing the exact pattern helps your doctor identify the likely cause.
