If you’re feeling dizzy, you may be searching for the underlying cause. Dehydration, medication, and a variety of conditions can cause you to feel dizzy and nauseous. While dizziness might seem like a mild condition, it can actually be very disruptive to daily life, sometimes with such severity that it leaves you bedridden for hours or days.

Among the many causes of dizziness are allergies. The inner-ear imbalance that can happen as a result of allergy-related sinus congestion and a blocked eustachian tube is easily treatable, however.

Causes of Airborne Allergy-Induced Dizziness

If you are allergic to certain airborne substances, including dust, pollens, and pet dander, your body begins releasing chemicals called histamines to fight off these perceived intruders. Those histamines cause the symptoms you know as allergy symptoms, including sinus congestion, sneezing, and coughing.

The eustachian tube connects your middle ear to the back of your throat.  When you begin experiencing symptoms in your ears, including that annoying clogged feeling that causes difficulty in hearing until it drains, it is because your eustachian tube is blocked. These middle-ear troubles can cause symptoms of dizziness in those suffering from allergies, colds, and sinus infections.

Lightheadedness may bealso a symptom of allergies. It is easily discernible from dizziness, since instead of the feeling that the room is spinning, you feel as though you might faint. Lying down usually resolves lightheadedness, at least temporarily.

Allergy-Induced Vertigo

Vertigo is a severe form of dizziness that causes a person to see the room as though it is spinning. A person with vertigo may also feel as though they are moving when they are sitting or standing still.

In the case of allergy-induced vertigo, the culprit is fluid building up in the middle ear. It’s important to note that while vertigo can be debilitating, it is treatable. Your doctor will likely run a variety of tests to determine the cause and, if it is determined to be related to allergic rhinitis, provide treatment accordingly. Since vertigo can be related to more serious issues, it’s important to seek treatment as quickly as possible once you’ve experienced the problem.

Causes of Food Allergy-Induced Dizziness

Lightheadedness and dizziness are common symptoms of food allergies. It is the body’s attempt to fight off this foreign substance, similar to the histamine reaction in airborne allergies. If you regularly have symptoms of dizziness, airborne allergies may not be the cause. You may have an intolerance to gluten or wheat.

Your symptoms can occur immediately after eating the offending food or hours later. For that reason, a person may not associate his or her dizziness with the food that has recently been ingested. It may not even be discovered until allergy testing reveals the sensitivity.


The cure for allergy-induced dizziness is usually to treat the cause. While prescription and over-the-counter medications are available to help relieve dizziness, treating the underlying cause is usually a more effective way to kick dizziness for good.

First, your physician will attempt to determine what is causing your dizziness. This is usually done by a traditional allergy test, with a detailed finding of your particular allergens. From there, you can decide what treatments are necessary.

There are many options for battling allergy symptoms. Antihistamines are popular for short-term use and can be very effective in relieving the congestion that can be causing your dizziness. Antihistamines are also used to treat vertigo.

Long-term, however, your doctor will likely want to treat the allergy causing the histamine reaction. This can be done with prescription medication that is safe for daily use, or can be done with specially formulated allergy shots that you will receive short-term to provide long-term results.

When you receive an allergy shot, you are actually being injected with the allergen. Over time, this helps desensitize your body to the allergen. By gradually increasing your dosage, your body gradually adjusts and over time, your symptoms decrease.

If your dizziness is food-related, a change in diet will likely become necessary. A gluten-free or wheat-free diet may be recommended, but luckily there are many options on the market today to address these special dietary needs. Your doctor may monitor you for signs of celiac disease, a more serious form of gluten intolerance that requires complete avoidance of gluten in your diet or serious health complications can follow.
