Allergies are among the most common conditions that affect millions of people worldwide. They result from an overreaction of the immune system to certain substances that are usually harmless, such as pollen, dust mites, or certain foods. Most people associate allergies with common symptoms like sneezing, runny nose, itchy eyes, and hives.

However, there are some uncommon symptoms of allergies that can be confusing. In this post from QEStrong, we will explore some of the uncommon signs of an allergy that you should be aware of:

Uncommon Symptoms of an Allergy

1. Fatigue

Fatigue is one of the less-discussed symptoms of allergies, but it is a common one nonetheless. Allergies can cause fatigue in various ways, from dehydration due to excess mucus production to an increased need for sleep due to an overly active immune system.

Allergies can also cause difficulty in breathing, which can lead to decreased oxygen intake, causing fatigue. Additionally, the body’s need to fight off allergens can cause the body to become tired as it works to protect itself. If you experience frequent fatigue and think it may be related to allergies, it’s important to talk to your doctor.

2. Dizziness

Allergies can manifest in many ways, and some of these symptoms can be unexpected. One of the more unexpected symptoms of an allergy is dizziness. While it’s not necessarily a common symptom, dizziness can be a frequent occurrence for some people with allergies.

Dizziness associated with allergies results from decreased blood pressure and oxygen levels. When your body is dealing with an allergic reaction, it releases histamine, which constricts blood vessels supplying oxygen and blood to the brain. This can cause dizziness, lightheadedness, or even fainting.

3. Headaches

Headaches are a common symptom of allergies, and many allergy sufferers experience them. In fact, it’s estimated that up to 20% of people with allergies suffer from headaches. These headaches may be caused by the body’s response to allergens, such as histamine, or by changes in the environment that trigger an allergic reaction.

Allergy headaches can vary in intensity and duration, from mild to severe. They may be localized to one area of the head or be more widespread. Common symptoms include:

4. Digestive Issues

Digestive issues are an often overlooked symptom of allergies. If you have an allergy, it can cause inflammation in your digestive tract, leading to uncomfortable and sometimes serious problems. 

Symptoms may include nausea, vomiting, abdominal cramps, bloating, diarrhea, and constipation. In some cases, food allergies can also cause irritable bowel syndrome (IBS) and chronic indigestion. 

5. Joint Pain

Joint pain is an uncommon symptom of allergies that can be confusing for many people. Allergies can cause inflammation throughout the body, which can lead to joint pain and stiffness. This can be especially problematic for people who already have joint issues, such as arthritis, as they could be taking pain relief medication when they should be taking antihistamines.

6. Breathing Difficulties

Breathing difficulties are a common symptom of allergies, but they can also be an uncommon symptom. Allergies can lead to inflammation in the airways, which can lead to wheezing, shortness of breath, and even asthma attacks. This can be especially problematic for people who already have respiratory issues.


Allergies can cause an array of symptoms, some of which may be uncommon and confusing. It is crucial to be aware of these uncommon symptoms so that you can recognize them and seek medical attention if necessary to get allergy relief.

If you have allergies and experience any of these symptoms, talk to your doctor about how to get allergy relief, manage your condition, and prevent complications.
