Yes, allergies can cause dizziness. Usually, dizziness caused by allergens can be airborne allergy-induced or food allergy-induced. Allergies can block your Eustachian tube with mucus. As a result, it won’t be able to equalize pressure in the ear and maintain the body’s balance, thus causing the symptoms of dizziness. On the other hand, food allergy-induced dizziness may come from an intolerance to gluten, wheat, or other food products. The symptoms might surface immediately after eating the food or hours later.
