Red and itchy skin, cough and sneeze around an allergen -means you are having allergy! Such a awful and frustrating condition. When your immune system interacts with an allergen (foreign substance) like bee venom, pet dander or a pollen, it causes a exaggerated allergic reaction in a sensitive body. Although many individuals outgrow allergies gradually, but it can affect any person at any age.
Immune system is a complex system that normally defends your body against foreign elements and substances such as viruses and bacteria. This system produces substances known as antibodies which stops and kills unwanted invaders that could make you ill or cause an infection. When you have a defective yet sensitive immune system, it makes you allergic to certain substances. When you come contact to that allergen, it can cause you get some sort of allergic response, which may make you cough or sneeze, inflame your skin etc.
The disease which come under the category of allergy include:
- Hay fever
- Food allergies
- Atopic dermatitis
- Allergic asthma
The word allergy was originated as ‘’Allergie’’ in Greek language. The word ‘’allergy’’ was first used in 1906, by Clemens von Pirquet. To get an allergy is a common phenomenon. About 20% of the people are affected by allergic rhinitis, 6% of people have atleast one or more food allergies, 18% people have asthma, 0.05-2% of the people have anaphylaxis and 20% people have have atopic dermatits.
CAUSES OF ALLERGIES:
Immune system is a vast system that helps to protect your body against invading pathogens and invaders. When a harmless substance enters in your body, sometimes, the immune system makes a mistake and consider it as a harmful pathogen. The immune system automatically starts to make antibodies for that particular agent. Now, when you are exposed to that agent again, those antibodies that were produced before, releases a number of chemicals to kill that harmless substance. These chemicals are the reason for the allergic reaction.
Substances that mostly induce allergy include:
- Some foods, such as tree nuts, milk, eggs, shellfish, soy, fish, wheat, peanuts and beetle nut.
- Airborne allergens, particularly pollen, dust mist, mold and animal dander.
- Medications, like penicillin.
- Insect stings such as bee stings or wasp stings.
