Can Allergies Cause Headaches and Dizziness?
Yes, allergies can definitely cause both headaches and dizziness through several mechanisms. Sinus congestion from allergic reactions creates pressure that triggers tension headaches and sinus headaches in up to 60% of allergy sufferers. Inflammation blocks proper drainage, leading to fluid buildup that affects inner ear balance and causes dizziness. Histamine release during allergic reactions can also dilate blood vessels, contributing to headache pain. Common triggers include seasonal pollen, dust mites, pet dander, and food allergens. The combination of nasal congestion, post-nasal drip, and sleep disruption from breathing difficulties creates a cycle that worsens both symptoms.
