What is allergy?

Allergy is a condition characterised by a level of sensitivity greater than normal to a specific substance or group of substances. These substances, called allergens, trigger a response in susceptible individuals. The allergens may be found in the ticks, moulds, food, pollen, pets, and dust mites.

A genetic tendency to develop allergic disease in a body is known as atopy. When the allergens come in contact with the people who are atopic, an immune gets developed which further leads to allergic reactions and inflammations. When the allergens come in contact with the person of a specific allergy then the possibility allergic reaction increases by many folds.

An antibody response is triggered by the body as soon as the allergen enters the body. The attachment of antibodies to the mast cells takes place. The reaction of the mast cell is to release histamine. If the histamine is released due to an allergen then it might lead to irritation and inflammation.

Histamine produced by the immune system protects against harmful irritants like mold, dust, and pollen. It helps to preserve water in the body. Once an individual is dehydrated, the production of histamine is enhanced by the body. This in turn results in symptoms similar to seasonal allergies. Hence, drinking sufficient water will not allow excessive production of histamine and decrease the Allergy symptoms.

There are no specific side effects to treating allergies. However, for people who are very vulnerable to multiple allergies, it is important to note that you may even be allergic to some of the ingredients that are used to create different medications.
