Allergy is a hypersensitivity disorder of the immune system. Substances known as allergens are the reason for this disease. It happens when there is excessive activation of mast cells and basophils by a type of antibody known as IgE, which cause extreme inflammatory response.
Common allergens are: pollens, mold spores, house dust mites, animal danders, foods, insect bites or stings, plants, viruses, bacteria and even environmental conditions like cold temperatures.
Common allergic reactions include eczema, hives, hay fever, asthma attacks, food allergies and reactions to the venom of stinging insects such as wasps and bees.
Causes of Allergies
The basic cause of allergy is still not known. A person who is allergic is more likely to have relatives who are allergic. But, non-hereditary factors also play an important part.
Types of Allergies
The most common allergic diseases are allergic rhinitis, non-allergic rhinitis, asthma, allergic dermatitis, contact dermatitis and urticaria.
Allergic rhinitis: Allergic rhinitis also known as ‘hay fever’ can be a seasonal problem or a year-round problem. Hay fever or seasonal allergic rhinitis is caused by allergy to grasses, weeds, pollens of trees or mold spores. Another form is the Perennial allergic rhinitis which is caused by house dust, animal danders, mold and some foods.
The signs and symptoms of allergic rhinitis include sneezing, often accompanied by a runny or clogged nose coughing and postnasal drip itching eyes, nose and throat.
1)Eating a healthy diet, with foods rich in vitamin B and C.
2)Every day, eat a teaspoon of honey as it strengthens resistance to local plant pollens.
3)Drinking a cup of ginseng or Echinacea tea daily also strengthens one’s immune system.
