Allergy is a condition in which the body tends to react due to hypersensitivity to some substance such as food, drugs, drinks, pollution, flowers, and others. An allergen could be anything under the sun that might cause a reaction in one’s body if the body disagrees with that substance. Even a common thing such as sunlight and air might cause sever reactions in some if the skin is susceptible to allergies due to the same.

When someone is exposed to an allergen

An allergy is the body's reaction to a substance - known as an allergen - which does not normally produce adverse effects in the majority of people. Allergens can be encountered in different environments and in different ways such as by breathing, eating or drinking, touching, being near or having them injected into your body.

These days of increasing pollution levels mean that more and more people are becoming victims of a variety of allergens, which are the various substances that cause an allergic reaction. These can be anything from a certain type of food coloring to pet dander or even a certain chemical that is present in seafood. There are also more and more children being born with allergies, so there is an all-over rise in the incidence of allergies.

Of all the diseases related to the respiratory system, asthma allergy is the most prevalent. This condition is usually visible in children and young adults, but the process may progress throughout their lives. Asthma allergy is a lung disease characterized by difficulty in breathing, wheezing, coughing, and the increase in production of mucus during an attack. The symptoms may bring simple discomfort or they may eventually lead to death, depending on the number allergens that affect the patient, causing blockages in the airways.
