Allergies are a common problem for many people. In fact, over 50 million Americans suffer from allergies each year. While most people know that symptoms such as a runny nose and itchy eyes are caused by allergies, there are quite a few other symptoms that you may not realize are also caused by allergies.
In this article, we will discuss some of the most common allergy symptoms that people often mistake for other conditions. Read on to learn more!
Symptoms Caused by Allergies
According to the American College of Allergy, Asthma, and Immunology (ACAAI), some people may not even realize they have allergies because their symptoms are mild or mistaken for other conditions. Here are a few things you may be experiencing that could actually be caused by allergies.
#1 – Asthma
If you have asthma, it is likely that you also suffer from allergies. In fact, about 80% of people with asthma also have allergies.
Allergies are a common trigger for asthma attacks and can make your symptoms worse.
If you have asthma and find that your symptoms are getting worse, it may be time to see an allergist to see if allergies are the cause.
#2 – Coughing
A cough is a common symptom of allergies, especially if you are also sneezing and have a runny nose.
Allergies can cause your throat and airways to become inflamed, which can lead to coughing.
If you have a cough that is not going away, it may be time to see an allergist to find out if allergies are the cause.

#3 – Dry skin or Eczema
Eczema is a common skin condition that can be caused by allergies.
It causes itchy and dry skin and can be aggravated by certain substances, like pollen or pet dander.
If you have eczema, you may need to use a moisturizer or corticosteroid cream to relieve the symptoms.
You should also avoid triggers, like certain fabrics or perfumes.
If you can’t control your eczema with over-the-counter treatments, see your doctor. They may prescribe a stronger medication.
#4 – Sinus infection
Sinus infections are common in people with allergies.
Allergies can cause your sinuses to become inflamed, which can lead to a sinus infection.
If you have a sinus infection that is not going away, it may be time to see an allergist to find out if allergies are the cause.
#5 -Headaches
You get them typically because your sinuses get filled up, and that pressure can give you a headache.
But if you have allergies, the inflammation in your sinuses can also cause headaches.
If you have headaches that are not going away, it may be time to see an allergist to find out if allergies are the cause.
#6 – Irritability
It’s not just you, allergy sufferers do tend to be more irritable.
When your body is fighting off allergies, it releases histamines.
Histamines are chemicals that cause all the symptoms of allergies, like runny nose and watery eyes.
They also can make you feel tired and cranky.

#7 – Brain fog
Allergies can make it hard to concentrate and make you feel like you’re in a fog.
When your sinuses are inflamed, it can block the passages that drain fluid from your brain.
This can lead to increased pressure in your skull, which can cause headaches.
But even without the headaches, the inflammation can make it hard to think clearly.
If you’re feeling like you can’t focus, allergies may be to blame.
#8 – Mood swings
Allergies can make you feel irritable and moody.
Histamines can affect your central nervous system, which can lead to feelings of anxiety and depression.
If you’re feeling unusually cranky or down, allergies may be the cause.
Talk to your doctor if you think allergies are affecting your mood.
They can help you manage your symptoms and feel better.
#9 – Sore throat in the morning
If you wake up with a sore throat, it could be from a postnasal drip.
Postnasal drip happens when your body produces too much mucus.
It can be caused by allergies, colds, or sinus infections.
The excess mucus drips down the back of your throat, which can irritate it.
Gargling with salt water can help soothe a sore throat.
You can also try over-the-counter medications like lozenges or cough drops.
If your sore throat lasts more than a few days, see your doctor. They can determine if you have an infection and prescribe antibiotics if necessary.
#10 – Vomiting
While vomiting can be caused by a number of things, including the stomach flu, food poisoning, and migraines, it can also be a symptom of allergies.
If you vomit soon after eating or drinking something, it could be a sign that you’re allergic to it.
Other allergy symptoms like hives, difficulty breathing, or swelling of the face, lips, or tongue can also cause vomiting.
If you have any of these symptoms, seek medical help immediately.

#11 – Nausea
Like vomiting, nausea is another symptom that can have a number of causes.
But if you feel nauseous after eating or drinking something, or smell something that triggers your allergies, it could be a sign that you’re having an allergic reaction.
If you have other allergy symptoms along with nausea, seek medical help right away.
#12 – Chronic fatigue
If you’re constantly tired and don’t have a lot of energy, it could be a sign that you have allergies.
Allergies can cause chronic fatigue because your body is working overtime to fight the allergens.
If you’re always tired and think allergies may be to blame, talk to your doctor.
They can help you figure out what’s causing your fatigue and how to treat it.
#13 – Sleep problems
Allergies can also make it hard to sleep.
If you have allergies and often wake up feeling tired or with a headache, it could be due to your allergies.
Talk to your doctor about ways to manage your allergies so you can get a good night’s sleep.
#14 – Itchy ears
Itchy ears are another common symptom of allergies.
If you have itchy ears, it could be due to an allergic reaction.
Talk to your doctor about ways to manage your allergies so you can get relief from your symptoms.

#15 – Frequent infections
If you have allergies, you may be more likely to get infections.
This is because allergies can weaken your immune system.
Talk to your doctor about ways to manage your allergies so you can reduce your risk of infection.
