Dizziness is a sensation of spatial disorientation that often leads to feeling faint, unsteady or lightheaded. Many people describe dizziness as feeling “like the room is spinning,” Some people may become dizzy from simple actions, such as  going on an amusement park ride or not having enough to eat.  However, frequent or lengthy episodes of dizziness may signal a more serious underlying cause, such as heart disease.

Most episodes of dizziness are not related to serious conditions and often quickly resolve without treatment. However, people are encouraged to see their physician if they have any unexplained dizziness, especially if is accompanied by other symptoms.

The most serious cardiovascular conditions that can lead to dizziness include a severe drop in blood pressure, abnormal heart rhythm (arrhythmia) heart attack and stroke. In many of these cases, there may be additional signs or symptoms, such as chest pain or heart palpitations.
