Dizziness as a Symptom of Food Allergies

Is it possible that your food allergy is making you dizzy? May sound strange but in fact, there are cases in which food allergies can cause one to be dizzy. And for anyone who has experienced this symptom, they can attest that being dizzy can be very debilitating. Once in a while, you might manage to lay low, but for those who experience this for days in a row, it can leave you bedridden for hours and hours.

So what is it that causes the allergy induced dizziness? If you allergic to airborne substances your body begins by releasing chemicals called histamines to fight off what are perceived to be intruders. The histamine reactions include sinus congestion, itchy throat, coughing, and sneezing, all of which become commonly known as allergy symptoms. These allergies then affect the Eustachian tube, which is the tunnel that connects the middle ear to the back of your throat. This tube plays an important role in regulating balance. It also plays a role in equalizing the pressure in your middle ear with ambient air pressure. When the Eustachian tube is blocked with mucus it results in the clogged feeling that makes it difficult to hear. Additionally, it no longer is able to equalize pressure in the ear and maintain balance in your body. This will then lead to dizziness in those with allergies, cold or since infections.


It is important to recognize that dizziness and lightheadedness are often believed to be one-in-the-same, however, they are very different. Lightheadedness can lead to feeling as though you might pass out or that the room is spinning but once you lie down it is often resolved. It is often a very temporary feeling that often can also be relieved by drinking fluids or taking in something with sugar, as it can be caused by a drop in pressure or sugars.

Dizziness on the other hand usually does not get resolved just from lying down or taking a drink and appears to last longer and be more intense in feeling.  

Food allergies are sometimes linked to both lightheadedness and dizziness. As your body tries to fight off foreign substances, these symptoms may arise. Typically intolerances to gluten or wheat, among some other foods, can be a cause of dizziness. For those who are experiencing this due to a food allergy, the dizziness may start as early as right after eating the offending foods or may show up hours and hours later. Some people even experience exercise-induced food allergy symptoms, which include the feelings of dizziness or lightheadedness as well. Food intolerances tend to not show up for hours or even days later, making it hard to identify the true cause of the dizziness. This may take require extensive testing and further evaluations to determine which foods are the cause. 

Curing the allergy-induced dizziness means avoiding the allergen itself. If it is caused by airborne allergens, it is often suggested to use prescription and over the counter medications to help relieve the symptoms and dizziness. When it is ingesting the food itself that causes the dizziness, then avoiding that food is the way to cure the symptoms.

Some people even experience exercise-induced food allergy symptoms, which include dizziness or lightheadedness as well. 

Seeking medical attention to determine what food allergies you might have is the first step in understanding the true cause of the dizziness and other allergic responses you may be experiencing.  Once the doctor determines its causes, through a series of blood tests, skin tests or elimination diets, then dietary changes can be made.  

The good thing is that once the true cause of the dizziness is determined appropriate treatment can be found. When it is connected to a food allergy, following a new allergen-free diet will help the dizziness to resolve itself and life can continue as normal.
