What Characterizes Food Allergy?
Food allergy represents one of the less frequent types of
allergy. According to the statistical data that has been
gathered recently, only 2 percent of the adults and 6 percent
of the children manifest the symptoms of food allergy. The
other people who believe that they have food allergy suffer, in
fact, from food intolerance.
However, it is very important to know that these two health
conditions are very different. First of all, food intolerance
has mild symptoms and does not imply the immune system. Food
allergy, on the other hand, may even lead to anaphylactic shock
sometimes. In addition, in food allergy, the immune system
plays a very important role.
When people who are allergic to a certain food consume
it, the immune system releases a chemical substance, called
histamine, in order to neutralize the proteins from the food.
The reason why these proteins are mistaken for dangerous bodies
is unknown. The scientists continue the research in order to
pinpoint exactly the cause of all the types of allergy. When
histamine is set free into the body, the allergic reaction is
triggered and the food allergy symptoms become observable.
It is very important to know that the symptoms become obvious
within a few hours after consuming the food that triggers the
allergic reaction. In some cases the allergic reaction is mild
while in other cases, it may even be lethal. The severity of
the symptoms depends on the immune system of each person. Most
frequently, the symptoms include hives, itch of the skin,
stuffed nosed, dizziness, nausea and vomiting.
The respiratory tract is also affected, so it is not
uncommon for people who are allergic to a certain food to
experience wheezing, shortness of breath or even long
congestion. In rather rare cases, people have reported that
they have allergy asthma. Anaphylaxis, which represents the
most serious allergic reaction, the symptoms include
obstruction of the respiratory ways, shock, dizziness and loss
of consciousness. The blood pressure of a person who enters
anaphylaxis drops significantly. The pulse is either fast or
very weak.
When the food that causes the allergic reaction is known, the
best way to avoid the problem is to stay away from that certain
food. When that particular food is consumed, in order to
prevent the symptoms, an injection with adrenaline or
epinephrine must be made. This treatment is recommended only in
dangerous situations. For people who have less severe symptoms,
the doctor will recommend a treatment based on
antihistamines.
