I feel dizzy often, maybe once or twice a day. it started off once a week but its gotten worse. why?

Dizziness : Hard to know the cause but progressive symptoms warrant a visit to the doctor. There are three main types of dizziness: 1) vertigo or spinning of the room; 2) lightheadedness (faint feeling); and 3) imbalance (falling to one side or incoordination). Each type of dizziness has different causes and originates from different areas of the body.
