Do Allergies Cause Fever?
August 26, 2023 | by Yashaswi Pathakamuri | Posted in FAQ's
Allergies themselves typically do not cause fever. Fever is generally a response of the body’s immune system to infections, inflammation, or other immune-related triggers. Allergies, on the other hand, are immune responses to harmless substances (allergens) that the body identifies as potentially harmful.
However, it’s possible for allergies to indirectly lead to a slightly elevated body temperature or a feeling of warmth. Here’s how:
- Systemic Allergic Reactions: In some cases, severe allergic reactions known as anaphylaxis can occur. Anaphylaxis is a medical emergency that involves a rapid and severe immune response to an allergen. During anaphylaxis, the body releases chemicals like histamine, which can lead to a drop in blood pressure and an increased heart rate. These physiological changes could potentially result in a feeling of warmth or mild elevation in body temperature, but not a true fever.
- Inflammatory Responses: Allergic reactions can cause inflammation in the body. While this inflammation is not the same as an infection, it might lead to feelings of discomfort, warmth, or malaise, which could be mistaken for fever by some individuals.
- Secondary Infections: In some cases, allergies can lead to symptoms like congestion, runny nose, or irritated throat. These symptoms might make you more susceptible to secondary infections, such as a cold or sinus infection, which can cause fever.
It’s important to note that if you’re experiencing symptoms that you suspect might be due to allergies or an allergic reaction, it’s a good idea to consult a healthcare professional for proper evaluation and diagnosis. If you have concerns about fever or other symptoms, a healthcare provider can help determine the underlying cause and provide appropriate guidance and treatment.
