The increasing number indicates our combat against infectious and increased personal hygiene may have affected the mechanisms.

Allergies causes also due to Global warming which has an effect on changing forms of natural vegetation and more profuse pollen productions.

Development of Allergies cause

Right from birth, the immune system suits more to the allergies (TH2) or is Liable to the allergies (TH1), depending on heredities and the environment. TH positions for T helper type of white blood cells. 

TH1 immunity is good for combat against bacteria and viruses and protects against allergies. TH2 immunity is worthy in fighting parasitic infections but makes us more exposed to developing allergies.

Hyposensitisation (immunotherapy)

This is another form of Allergy treatment is hyposensitization, also called immunotherapy.
Hyposensitisation works by progressively familiarizing a little more and more of the allergen into your body to make it a reduced amount of sensitivity to it.

Allergens are generally injected under the skin of the upper arm. In the starting stages of treatment, you will be given shots at pauses of a week or less, after that allergen doses are progressively increased. 

When you touch the ‘maintenance dose’ period, a dose that is very operative in reducing your usual allergic reaction, allergens will have to carry on to have shots of this dose every few fortnights for at least 2 years.

Hyposensitisation is usually only suggested for the treatment of extreme condition allergies for example such as hay fever and pet allergies which have not yet reacted to other allergies treatments, and for explicit allergies such as bee and wasp stings which are normally painful.

This treatment should only be carried out under the close administration of a doctor as there is always a risk that it may cause a severe allergic reaction to the allergen.
