What Causes Allergic Reactions?

Before we move ahead, let’s understand what causes allergic reactions in general. Our immune system plays a vital role in keeping us healthy by fighting off harmful viruses and bacteria that enter our body.

Sometimes, our immune system mistakenly identifies harmless substances known as allergens as dangerous invaders and tries to fight them off using chemicals such as histamine which results in reactions like watery eyes, sneezing, coughing etc.

This occurs because of unique sensitivity to specific substances, which includes but is not limited to dust mites, peanuts, bee stings or even certain medications such as penicillin.

Symptoms Of An Allergy

Symptoms vary based on the severity of the allergy and could range from mild itching sensations all over your body (the famous Chickenpox) to full-blown hives accompanied by inflammation of blood vessels (Swelling) under skin surface layer; if left untreated it may result in difficulty breathing or even loss of consciousness- Often leading patients taking Epinephrine.
