Allergy is an exaggerated response of the immune system. Allergy or allergic reactions occurs when a person’s immune system reacts to normally harmless substances in the environment. A substance that causes allergic reactions is called allergens.
Mild allergies like light fever are very common in the humans and cause symptoms such as redness of eyes, itchiness, and runny nose, eczema, or an asthma attack. Allergies can develop at any stage of life. It also depends upon your parent’s allergic history.
What causes allergy?
Allergies can develop at any age. Possibly even in the womb. They commonly occur in children but may give rise to symptoms for the first time in adulthood. Asthma may persist in adults while nasal allergies tend to decline gradually with age.
Allergy can be hereditary. It may also depend upon gender and race. Infectious disease and environmental pollution are also responsible for causing allergy.
One of the most common food allergies is due to peanuts. Peanut allergies may be extremely severe. Nuts from trees, including pecans, pistachios, pine nuts, and walnuts, are another common allergen. Sufferers may be sensitive to one, or many, tree nuts. Seeds, including poppy and sesame contain oils where protein is present, which may elicit an allergic reaction.
Egg allergies affect one to two percent of children but are outgrown by about two-thirds of children by the age around 5. The sensitivity is usually to proteins in the white rather than the yolk.
Milk, from cows, goats, or sheep, is another common allergy-causing food, and many sufferers are also unable to tolerate dairy products like cheese. Other foods containing allergenic proteins include fish, wheat, soy, shellfish, fruits, vegetables, spices, synthetic and natural colors, chicken, and chemical additives.
