People who suffer from various ear infections often feel lightheaded. These people tend to have a desire to vomit even without any reasons. When the auditory system suffers, people may perceive different sounds inadequately, which even may force them to vomit. Ear infections negatively impact balance systems. It all resulted in the lack of balance of movements, nausea, and feeling you want to vomit. If the main cause of the infection is a specific virus which attacks the entire body, dizziness is a typical symptom.
