Dizziness symptoms overview dizziness-symptoms

Dizziness symptoms can usually be more specifically described as one of the following sensations:

• The false sense of motion or spinning (vertigo)
• Lightheadedness or the feeling of near fainting
• Loss of balance or unsteadiness (disequilibrium)
• Other sensations such as floating, swimming or heavy-headedness

A number of underlying health conditions can cause these problems. Some of these conditions disrupt or confuse the signals your brain receives from one or more of your sensory systems, including your:

• Eyes, which help you determine where your body is in space and how it’s moving
• Sensory nerves, which send messages to your brain about body movements and positions
• Inner ear, which houses sensors that help detect gravity and back-and-forth motion

When to see a doctor

See your doctor if you experience any unexplained, recurrent or severe dizziness.

Call 911 or emergency medical help or go to the emergency room if you experience new, severe dizziness or vertigo along with any of the following:
