The definition of allergy 

In particular, allergies are affecting around one in five people. In the first place, there are many reasons for allergy and symptoms that vary from mild to life-threatening. Generally, allergy is one of the main characters associates with the cause and persistence of asthma. An allergy occurs when a person reacts to substances in the environment that are harmless to most people. These substances are known as allergens and are found in dust mites, pets, pollen, insects, ticks, moulds, foods and some medications.

Atopy is the genetics reason to produce allergic conditions. When atopic people are caught to allergens they create an immune effect which leads to allergic swelling. As a result, this can cause signs such as:

  • Nose and/or eyes, developing allergic rhinitis (hay fever) and/or conjunctivitis.
  • Skin appearing in eczema, or hives such as (urticaria).
  • Lungs resulting in asthma.

What happens when an allergic reaction occurs?

When a person who is allergic to a particular allergen comes into contact with it, an allergic effect happens:

  • When the allergen (such as pollen) enters the body, it triggers an antibody response.
  • The antibodies attach themselves to mast cells.
  • When the pollen comes into connection with the antibodies, the mast cells respond by releasing histamine.
  • When the release of histamine is due to an allergen, the resulting swelling (redness and inflammation) is annoying and painful.

Related effects can happen to some chemicals and food additives. However, if they do not affect the immune system, they are known as adverse reactions, not an allergy.

Allergy attacks which part of the body?

People feel many types of symptoms, depending on the type of allergen and from where it enters the body. Therefore, an allergic reaction may include many parts of the body at the same time.

Nose, eyes, sinuses and throat

When allergens enter our body while breathing through the nose, it secretes histamine which causes the lining of the nose to produce more mucus and become swollen and inflamed. Together with it causes itchiness in the nose, and severe sneezing may occur. In addition, eyes may start to water and people may get a sore throat.

Lungs and chest

Asthma can also trigger during an allergic reaction. When you breath an allergen, the lining of the passages in the lungs swells and makes breathing difficult

Stomach and bowel

Generally, foods that commonly cause allergy include peanuts, seafood, dairy products and eggs. Cow’s milk allergy in infants may occur and can cause eczema, asthma, colic and stomach upset. For the most part, some people cannot digest lactose (milk sugar). Lactose intolerance causes stomach upsets, but should not be confused with allergy.

Skin allergy

Atopic dermatitis (eczema) and urticaria (hives) can trigger skin allergy.

Life threatening allergic reactions require immediate treatment

In this case, most allergic reactions are gentle to moderate and do not cause extreme problems. However, a small number of people may experience a critical allergic reaction called anaphylaxis, which needs urgent life-saving medication. Generally, allergens which may cause anaphylaxis include foods, insects and medications. People with a severe allergy should have an ASCIA Action Plan for Anaphylaxis

Effective prevention and treatment options are available

Reducing dust mite in the home may help reduce symptoms in people who are allergic to mites. Such as, drugs which are used to treat allergies are: 

  • Antihistamines block histamine flows from the mast cells, reduces symptoms. Non-sedating antihistamine tablets are available from the chemist without a prescription. Antihistamine nasal and eye sprays are also available.

  • Medicated eye drops can be helpful in some cases, ask your doctor or pharmacist for advice.
  • Adrenaline (epinephrine) – is used for first aid emergency treatment of life-threatening severe allergic reactions (anaphylaxis).  Adrenaline is usually given using an adrenaline autoinjector that can be given without medical training.

Non-medicated treatments such as saline sprays are used for treating allergic rhinitis and sinusitis.

Allergen immunotherapy (also known as desensitisation) is a long-term treatment which changes the immune system’s response to allergens. Generally, it includes the management of routine, slowly increasing amounts of allergen extracts, by injections or by sublingual tablets, sprays or drops.
