If you feel like your allergies spin you “right ’round, baby, right ‘round” … well, you’re not wrong. This is a relatively rare symptom, but it’s possible.

You’re probably already familiar with standard allergy symptoms: runny nose, itchy eyes, sneezing and the like. But you might not realize that issues like dizziness (feeling off-balance) and vertigo (feeling like you’re spinning) can be a direct result of your allergies, too.

“I’d estimate that maybe 5% of my patients are specifically referred for these reasons,” says allergist Mark Aronica, MD. He explains what causes allergy-induced dizziness and what to do if it’s happening to you.

Why allergies make you dizzy

Your Eustachian tubes are tiny tubes that connect your ears to your sinuses. They drain fluid and equalize the air pressure inside of your ears, which contributes to your sense of balance. They also lead to your vestibular system, located in your inner ear, which is responsible for sending your brain signals about balance.

It makes sense, then, that if your Eustachian tubes are swollen or blocked, you may start experiencing dizziness or vertigo. And what can cause your Eustachian tubes to become swollen or blocked? You guessed it: allergies.

Inflammation and mucus build-up in your Eustachian tubes is called Eustachian tube dysfunction. And though it doesn’t always cause dizziness or vertigo, they can be among the symptoms.

“When you have inflammation in the nose and sinuses, you can also have inflammation in and around the Eustachian tubes, which can cause those tubes to narrow,” Dr. Aronica explains. “Fluid can then build up behind the ear and impact the vestibular system, which can cause dizziness.”

How to treat your dizziness

The best way to treat allergy-induced dizziness is to treat your allergies themselves. Whether you have spring allergies or fall allergies (or year-round allergies, ugh), management looks pretty similar: Avoid allergens, if you can, and turn to medication if you can’t. 

“When I see patients with dizziness, we try a nasal steroid spray to see if that reduces inflammation and opens up the Eustachian tubes,” Dr. Aronica says. “If their dizziness gets better, that suggests cause and effect.”

Prescription nasal steroid sprays like fluticasone and triamcinolone can ease the inflammation in your nose, sinuses and Eustachian tubes.

You can also ease your allergies with over-the-counter medications and prevent your symptoms from getting worse by keeping outdoor allergens out of your home. Keep your windows closed, bathe outdoor pets frequently and wash your clothes after you’ve spent time outdoors, especially if you’re doing something allergy-inducing, like hiking, raking leaves or mowing the lawn.

What if your dizziness is caused by something else?

“If a steroid nasal spray doesn’t work, I encourage patients to follow up appropriately with their primary care physician or the doctor who referred them — just to make sure we’re not missing something else,” Dr. Aronica notes.

A number of other conditions can cause dizziness and vertigo, so if your allergies aren’t the culprit, you may need to see a neurologist or an otolaryngologist (an ear, nose and throat doctor, commonly known as an ENT) to figure out what’s going on.

When to talk to your doctor

If you’re experiencing frequent dizziness or vertigo, you should make an appointment to get checked out — and if you know you’re also in the midst of a bout of bad allergies, be sure to tell your doctor so they can best assess the cause of your symptoms.
