Allergies with nasal congestion can result in dizziness and sometimes hearing loss. If you suffer with allergies, whenever you are exposed to an allergen (pollen, dust mites, mold, food, animal dander, or chemicals), the chances are good that you may have dizziness. As the mucus produced from the allergic reaction subsides, usually the dizziness will go away.Allergies cause a constant runny nose, ongoing sneezing, swollen nasal passages, excess mucus, weepy eyes, and a scratchy palate and throat. A cough may result from postnasal drip. Some people with allergies feel only a drippy nose; others are so congested that the allergy affects every part of their lives.
Infected ears and fluid in the eyes because of blocked Eustachian tubes are two common results of allergies in both adults and children.Viral or bacterial infections may also result in dizziness or vertigo. Mastoiditis, a serious infection that extends far into your inner ear, can destroy your hearing and equilibrium, resulting in feelings of dizziness.
