Age
Most allergies
manifest themselves between ages 15 and 25. An exception is cow's
milk allergy in small children. The earlier one develops allergic
symptoms, the higher the risk of developing more allergies later in
life. On the other hand, some people grow out of an allergy. In
many people, allergies diminish after the age of 40.
However, allergic symptoms appear to manifest themselves in an increasing number of older people. The causes of this trend are not yet entirely clear. What we do know is that moving house a lot may have an impact. In the old days, it was not nearly as customary to move once every few years. Every time you move to another place, the body is exposed to substances with which it is not yet familiar.
