Skin Allergy: Causes, Treatment and More.

by Zahra Ijaz · June 2, 2021

Skin Allergy can be a sign and symptom of different allergies. Moreover, they can be due to the direct result of exposure to an allergy.

An Allergy is an immune response to a foreign body or substance that is usually not harmful to your body.

These foreign substances or bodies are Allergens and they can include certain foods, pollen, or pet dander.


Skin Allergy

Skin Allergy is due to an immune response. The immune system in your body helps to keep you healthy by fighting harmful pathogens like bacterias, viruses, etc.

It does this by attacking anything that is not a part of your natural body. Moreover, depending on the allergen, this response can involve possible inflammation, sneezing, or a host of different symptoms.

For instance, if your body encounters pet dander,s and you are allergic to it, your immune response will attack it as a result of an allergy.

Skin Allergy

Allergens or molecules which can potentially cause allergy are present in the surrounding environment and are present in the form of pollen, food, mold, dust mites, or insect venoms.

When your body is threatened by these molecules or foreign bodies, it reacts with an immune response, thus we develop an Allergy.

Interestingly, no one is born with allergies. Instead, about 50 million people in the US suffer from allergies only when they come in contact with an allergen and develop an allergy.

Moreover, hayfever affects about 400 million people worldwide, with asthma affecting 300 million, food allergies between 200 to 250 million, and drug allergies affecting almost 10% of the world’s population.
