Lightheadedness

What is Dizziness?

When people say they feel "dizzy" it can mean many different things. What does dizzy mean to you? 

 

Feeling lightheaded usually means that you feel like you might faint or "pass out". Lightheadedness usually improves or disappears if you lie down. You might feel nauseated or vomit when you are lightheaded. 

 

Vertigo is a feeling that you, or things around you, are moving. You might feel like you are on a rollercoaster – like you are off balance, spinning or falling. With severe episodes of vertigo, you might feel sick to your stomach (nausea) and you may experience vomiting. You may also lose your balance and fall.

(see section on vertigo).
