Can allergies cause a fever?

Jun 30, 2021 | Fever

General idea

Are you wondering, “Can allergies cause a fever?” No, allergies do not cause a fever. But in some cases, they may lead to health problems that can result in a fever. Allergy symptoms typically include watery eyes, sneezing, a runny nose, or a skin rash. These symptoms can make you vulnerable to a viral or bacterial infection, which can cause a fever. So you can indirectly blame allergies for causing a fever. That said, let’s learn more about common allergy symptoms, fever, and its treatment in detail.

The Difference Between Allergies & Common flu

In viral or bacterial infection, your body triggers an immune response. White blood cells produce chemicals called pyrogens, which are responsible for your body’s temperature spike. This is your body’s natural response that helps to kill off heat-sensitive bacteria.

On the other hand, allergens cause no such reaction. During an allergic reaction, your body makes you sneeze and cough by releasing histamines. This only happens during allergic reactions. This is why you shouldn’t take anti-histamine medication for the common flu or cold.

Common Allergy Symptoms

Generally, allergy symptoms depend on the cause, known as an allergen. Depending on the person and specific allergen, allergy symptoms can include:

  • Watery eyes
  • Runny nose
  • Coughing
  • Sneezing
  • Sore throat
  • Swelling
  • Skin rash
  • Sinus pain or headache
  • Postnasal drip
  • Wheezing

Individuals that are allergic to a particular food can experience symptoms like diarrhea and nausea. However, suppose you experience a severe allergic reaction that jeopardizes your

breathing or loss of consciousness. In that case, you should immediately reach out for help. This condition is called anaphylaxis, which is a medical emergency. You can visit Pulmonary Medical Consultants. At our modern pulmonary and critical care medical practice, we use advanced technology and compassionate care to help our patients.

Can Allergies Cause Fevers Indirectly?

According to the American College of Allergy, Asthma, and Immunology, allergies don’t cause a fever. But if you experience a fever alongside allergy symptoms, this is likely because of a sinus infection.

Allergies can affect your immune system. You might feel weak when your white blood cells are busy fighting pollen. It’s not uncommon to get a cold or sinus infection during seasonal allergies. Sinuses having mucus invite bacteria. Thus, allergies can indirectly cause a fever.

So, if you experience a cold amid allergy season, make sure that you’re drinking plenty of water and resting your body to recover quickly.

Are You Sure Those Are Allergies?

Even if you do not have a fever, make sure to take good care of yourself. Allergies, if left untreated, can cause severe sinus infections and even asthma. Don’t try to self-medicate or ignore your symptoms. Because this can likely end up doing more harm than good. So, watch out for bad breath, colored mucus, or any chills. Speak with your physician about the proper treatment plans.

Final Thoughts

Can allergies cause a low-grade fever? In short, the answer is still no. However, they can indirectly help to cause viral or bacterial infection. If you’re experiencing seasonal allergies, don’t ignore them. Make a call to Pulmonary Medical Consultants to discuss your symptoms and possible treatment plans.
