Diseases That Cause Light Headedness & Stomach Sickness

Numerous diseases can cause lightheadedness and stomach sickness. According to the U.S. National Library of Medicine and the National Institutes of Health, dizziness is lightheadedness, or the feeling of imminent fainting 1. Lightheadedness occurs when there is inadequate blood flow to the brain. It is sometimes accompanied by nausea or the urge to vomit, although lightheadedness and nausea may be stand-alone symptoms. When they occur together, lightheadedness and nausea may signal an underlying disease.
