Other Allergies

Urticaria (Hives)

Urticaria (commonly known as hives) are mosquito bite like swellings on the surface of the skin that range in size from a few millimetres to several centimetres. They may last minutes or hours and can change shape from round to oval, forming rings or patches. The skin swelling seen in urticaria is due to the release of chemicals such as histamine from mast cells in the skin that causes small blood vessels to leak. They are often itchy, but sometimes may not be itchy at all. Read more...

Eczema (Atopic Dermatitis)

Eczema (Atopic Dermatitis) is a condition that affects the skin, causing redness, itching and oozing.

Eczema mostly occurs in infants, with around 1 in 5 children under 2 years of age affected1. It is common for people with eczema to have or develop allergies, suggesting that inherited (genetic) factors play a role in eczema development. There is currently no cure available for eczema, but it can be effectively treated and managed. Read more... 

Allergic Conjunctivitis

This a broad group of allergic conditions involving inflammation of the thin membrane that covers the inside of the eyelids and the eye, known as the conjunctiva. The commoner conditions are mild and do not affect the cornea, but the rarer diseases do involve the cornea and can be sight- threatening.

People with allergic conjunctivitis experience itching, watering and redness of the eye, and most people with these symptoms also have allergic rhinitis (or hayfever). Typically, seasonal allergic conjunctivitis follows exposure to pollen in the springtime and can be quite dramatic and debilitating. Perennial allergic conjunctivitis occurs all year round and is usually a milder form of conjunctivitis caused by more persistent exposures to allergens such as house dust mites.

Allergic conjunctivitis is triggered by the same allergens that trigger nasal allergies or allergic rhinitis. Seasonal allergic rhinitis is triggered by pollen in the air during Spring and early Summer and the pattern and plants causing it will vary from region to region. In Australia, grass pollen is the most common cause. Read more...

Allergic Rhinitis (hayfever)

Allergic Rhinitis (hayfever) is one of the most common allergic conditions, affecting 1 in 5 people in Australia. It is caused by the body’s immune system reacting to common environmental substances such as pollen, house dust mite, moulds and animal danders. Common symptoms include runny nose, rubbing of the nose, itchy nose, sneezing, itchy, watery eyes and blocked nose and snoring at night.

Many people with asthma also have allergic rhinitis. When allergic rhinitis is well controlled, asthma symptoms are easier to control as well. When symptoms are longterm, allergic rhinitis may be associated with complications such as snoring, chronic tiredness, ear and sinus infections.

Symptoms may be regarded as mild when there is no disturbance in sleep, leisure, school or work activities and moderate/severe when there is disturbance to sleep, leisure, school or work activities. Read more...
