What does it mean when you get light headed/dizzy and lips go numb?

Hyperventilation? One common cause is hyperventilation. This occurs when a person's breathing is faster and deeper than normal - and upsets their normal acid/base balance in the blood. Symptoms can include light-headedness, dizziness, numbness around the lips, and even severe cramping and spasm in the hands. It can be frightening - and sometimes it is brought about by anxiety. Holding your breath briefly may help.
