Can Allergies Cause Fever?

Fever

Allergies themselves typically do not cause fever. Fever is generally a response of the immune system to infections, certain medical conditions, or other triggers. Allergies, on the other hand, occur when the immune system overreacts to substances that are usually harmless, such as pollen, pet dander, dust mites, or certain foods. The symptoms of allergies are typically related to inflammation and irritation in the affected areas, such as the nose, eyes, skin, or respiratory system.

Common allergy symptoms include:

  • Sneezing
  • Runny or stuffy nose
  • Itchy or watery eyes
  • Skin rashes or hives
  • Itchy throat or ears
  • Wheezing or shortness of breath (in allergic asthma)

However, in some cases, severe allergic reactions known as anaphylaxis can occur, and these can lead to a sudden drop in blood pressure and difficulty breathing. Anaphylaxis is a medical emergency and can result in a fever, but it is not the allergy itself causing the fever; rather, it’s the body’s response to the severe allergic reaction.

If you experience fever along with allergy-like symptoms, it may be a sign of an underlying infection or other medical condition. Infections, such as the common cold or flu, can have symptoms similar to allergies, but they may also cause fever. In some cases, allergic rhinitis (hay fever) can make individuals more susceptible to secondary respiratory infections, which could lead to fever.

If you have persistent or concerning symptoms, including fever, it’s essential to consult a healthcare professional for proper evaluation and diagnosis. They can determine the cause of your symptoms and recommend appropriate treatment or management options.
