The most common causes of allergies are pollen and dust mites.

Besides these, there are a wide range of substances that can trigger an allergic response.

Pollen:
---------
Pollen is the seeds or spores released by flowers or plants during pollination phase of plants and usually is higher in summer. Some countries shows the daily pollen index in the media during summer to warm allergen sufferers the risks of allergy during this peroid.
Pollens irritate the sensitive mucusal lining of the nose and the epithelium of the skin causing inflammation and swelling.

Dust mites:
---------------
Dust mites are microscopic parasites who live on the skin flakes shed by the human body every day. They can found just about everywhere on the floor, carpets, on mattresses, pillows, bed covers, clothes and upholstery.
The faeces from the dust mite is the main substance which causes sneezing and wheezing.

House dust like dander from animals, cockroach faeces, bacteria, moulds, fungus spores and dust mites are the main cause of allergies in any family.

Moulds
-------------
Moulds are microscopic fungi with spores floating in the air like pollen.
They are usually found in damp areas indoors such as the basement or bathroom, as well as outdoors in grass, leaves, hay, or under plants.


Animal proteins
------------------
Proteins found in an animal's skin and saliva can cause allergy to skin, nose and lungs in some people.

Food allergens
------------------
Certain foods especially eggs, milk, nuts, and seafood, induce intestinal and skin reactions frequently in children who often outgrow it after puberty.

2.Antihistamines can help relieve symptoms such as sneezing and running nose.

3.Bronchodilators (theophylline and beta-agonists e.g. salbutamol) are used in cases of asthma to open the airways, relieve coughing, wheezing, shortness of breath and difficulty in breathing.

4.Corticosteroids such as dexamethasone may be given to relieve symptoms.
They also reduce the immune reaction to the allergens.
