An allergy is an immune response or reaction to substances that are usually not harmful. Allergies are very common. Both genes nad environment ahd a role. If both your parents have allergies, there is a good chance that you have them, too. The immune system normally protects the body against harmful substances, such as bacteria and viruses. It also reacts to foreign substances called allergens. These are usually harmless and in most people do not cause a problem.
A theory known as the "Hygiene Hypothesis" suggests that contrubute exposure to microorganisms in childhood in developed countries, leads to improper development of the adaptive immune system and a subsequent increased risk of allergic disease.

It is important to understand that most times your genes do not determine your health. Here are some ways that your genes and your environment can interact:.
The epigenome is the primary location of gene-environment interactions and can be altered by the environment both directly and indirectly. Epigenetic factors most famously histone modification and DNA methylation can switch genes on or off and determine what proteins are transcribed.
They are involved in many normal cellular processes and epigenetic changes are a natural part of human development. Some changes, however, can lead to disease. Some of these abnormal changes can lead to diseases such as:. Some environmental exposures and dietary factors can lead to abnormal changes in epigenetic pathways.
Because epigenetic changes are subtle and cumulative, it is difficult to know the true causal relationship between epigenetics and the environment.
Some factors that can lead to epigenetic changes include. Sometimes, friction rubbing or roughly stroking the skin will cause symptoms. Allergies may make certain medical conditions, such as sinus problems, eczemaand asthmaworse. Mostly, the part of the body the allergen touches affects what symptoms you develop. For example:.
