Three Surprising Symptoms Of Undiagnosed Allergies

Posted on

Having allergies isn't fun for anyone, but many people don't even realize that they have them. You could have multiple symptoms of allergies and not know that they're connected to each other, let alone caused by an allergic reaction. Read on to discover three surprising symptoms of allergies.


When your body is exposed to an allergen, it responds by trying to protect itself. This typically means releasing naturally-produced chemicals into the body in an effort to fend off the allergen. However, these chemicals can potentially leave you feeling tired. If you don't know what you're allergic to, you could be chronically exposing yourself to the allergen and end up feeling exhausted all the time as a result.

Unfortunately, finding the root cause of general lethargy can be tough, as exhaustion and lethargy can be caused by a wide variety of ailments. However, if you've already seen a doctor and been screened for common causes like anemia and didn't find the answer, it might be time to see an allergy specialist.

Stomach Pain

Believe it or not, undiagnosed allergies could potentially be making your stomach hurt on a regular basis. There are a few potential reasons behind this.

One of the most common causes is that your body may be producing more mucus while you're asleep in an effort to flush allergens out of your nasal passageways. This can cause nasal drip while you're sleeping. The mucus that drips down your esophagus eventually ends up in the stomach. Unfortunately, the human stomach isn't equipped to digest large amounts of mucus, so you may have pain in your stomach or vomit, especially after lying down for a long time.


Lastly, allergies can cause swelling throughout the body. The histamines that are released by the body when it has an allergic reaction can cause swelling nearly everywhere, including your eyelids, limbs, or even your throat. In severe reactions, this can lead to problems like anaphylaxis. However, with mild allergies, your frequently stuffed-up nose or bloated eyelids could actually be due to a mild to moderate allergic reaction.

Seeing an allergy doctor can turn your life around if you have undiagnosed allergies. Your doctor will perform tests to find out what exactly you're allergic to so you can avoid it in your day-to-day life. You may also be given medication to control the allergic reactions. If you're tired of dealing with the symptoms mentioned above, see an allergy doctor for relief.
