Nausea or vomiting sometimes accompanies lightheadedness. Symptoms usually improve or go away after lying down.
It is common to feel lightheaded occasionally. Lightheadedness often occurs when a person gets up too quickly from a seated or lying position (orthostatic hypotension).
Unlike vertigo, lightheadedness does not produce a sensation of movement. Vertigo causes a spinning or whirling sensation that may lead to nausea or vomiting, loss of balance, trouble walking or standing, and falling.
