An allergy is basically possible at any age. This way, even babies and children can develop an allergy early. The cause of the excessive immune response to normally harmless substances in babies and children is not known.
However, it is clear that the susceptibility to allergies is inheritable. Thus, children whose parents are allergy sufferers also develop an allergy with a probability of 50 to 80 percent. If only one parent is affected, the offspring will be affected in about 20 to 40 percent of the cases.
Environmental pollution such as car exhausts or chemicals in clothing or commodities can also promote the development of allergies.
Substances and substances that cause allergic reactions in children and babies can be of chemical, plant or animal origin. These are usually harmful to neither children nor adults. Typical allergy-causing substances are:
- Substances from plant protection products or cosmetics
- Ingredients of medicines
- Additives and ingredients in food
- Pollen from grasses and trees
- Animal skin and hair
- Spores of molds
- House dust mites
- Certain foods such as egg, nuts or cow's milk
