Allergic reactions are just a manner in which the body’s immune
system defends it against harmful agents. Sneezing, wheezing, coughing,
rashes, and a running nose are some of the symptoms of allergic
reactions to external stimuli. Identifying the allergens is the first
step in the treatment of allergies. Allergic reactions might affect one
spot on the body or all over the body and could be in a variety of
forms. Allergies are very common and some people are more prone to
these than others. Allergens can be inhaled, contacted through the
skin, swallowed, or injected. Nothing is exempt from the possibility of
being an allergen.
Severe cases of allergic reactions may
require a course of steroid treatment extending for a couple of weeks
to one month. While first-time exposure may produce only a mild
reaction, subsequent episodes can produce more serious allergic
reactions. Most reactions occur within a few minutes to several hours
after exposure. In some people, it is possible to see the reaction even
after 24 hours. Anaphylaxis is a sudden and severe allergic reaction
that occurs within minutes of exposure and is a condition that requires
immediate medical attention. The situation can get worse very fast and
lead to death in a matter of minutes if not treated.
Allergic
reactions could be mild, moderate, or severe. Rashes, hives, itching,
nasal congestion, and watery, red eyes are all signs of mild allergic
reactions. Other symptoms might indicate a moderate or severe reaction.
There are some ways of administering first aid to someone who has had
an allergic reaction. Calming and reassuring the victim should be your
first move because anxiety can worsen symptoms. If the person develops
an itchy rash, apply calamine lotion and cool compresses. Contact a
doctor immediately and get the person some professional help either at
home or in a hospital.
