Allergy isreaction of the human immune system to objects certain, which should no cause reactions in other people's bodies. The reaction can appear in the form of a runny nose, skin rash which itch, or maybe hard to breathe.
Objects that can trigger an allergic response are known as allergens. In most people, allergens do not cause a reaction in the body. However, in people who have allergies to these allergens, the immune system will react because it is considered harmful to the body. White blood cells, including basophils, are one of the components that play a role in causing allergic reactions.
Allergic reactions that appear in each person are different, from mild reactions such as sneezing to severe reactions, namely anaphylaxis. Allergic reactions that appear also depend on the type of allergen
Allergies are common in children and usually subside with age. However, in some people, the allergies they suffer from still appear even though they have entered adulthood.
Allergy Causes
Allergies are caused by the immune system's reaction to allergens that vary from person to person. . This can happen because the body overreacts to the release of an allergic reaction-triggering substance called histamine. Some examples of allergens are dust, dead pet skin, peanuts, insect bites such as cockroaches, exposure to caterpillars, drugs, plants (e.g. poisonous plants) and latex materials.
In certain cases, a person can also have an allergy to sperm, for example in the use of sperm for the face.
