This is a medical emergency that needs urgent treatment.

What exactly causes these allergies?

Again, substances that cause allergies are known as allergens. It can be anything, ranging from food to any external agents.

Allergies occur when the body’s immune system shows some reaction on exposure to that external agent. As if it were harmful to our body. Causing a start to a series of reactions that results in allergies. Allergies are thus a protective mechanism of our body but it’s long-lasting effects can be severe.

It is not clear yet why allergies happen to certain people. But it is observed that most people affected, have a family history of allergies or some closely related conditions. Such as asthma and eczema.

The number of people with allergies is increasing every year. The bulk of allergic disease mostly occurs in childhood, with asthma, allergic rhinitis, and eczema and food allergy.

Rhinitis is the inflammation of the lining of the nose. It is, clinically, a symptom of a runny red nose. Manifested by itching, sneezing, and nasal blockage (congestion).
