Dizziness Overview

Dizziness is a balance symptom (or circulatory symptom) where a person feels unsteady or faint. They may feel disoriented and unbalanced. It must be distinguished from similar symptoms such as giddiness, lightheadedness, faintness, and vertigo. Dizziness differs from vertigo, which is the more severe sensation of moving or that the room is spinning. There are many possible causes of dizziness ranging from minor problems (e.g. motion sickness, alcohol, etc.) to extremely severe disorders of the heart and lungs (causing inadequate blood oxygenation). Ear disorders such as an ear infection can cause dizziness. Meniere’s Disease is a chronic ear disorder causing episodic dizziness and vertigo. Low blood pressure disorders can cause dizziness and fainting. Psychological causes of dizziness include anxiety and panic attacks (hyperventilation). There are many other possible causes. Dizziness can be a medical emergency, as it may indicate brain conditions such as stroke. Seek immediate professional diagnosis of any dizziness symptoms.
