Food allergies are a common problem in kids. Nearly two
million children have food allergies in the United States. Some food allergies
are life threatening, even if the food is taken in very little quantity. Peanut
tops the list of notorious foods which cause allergies. Following it are milk,
especially cow’s milk, soy, eggs, wheat, seafood and other nuts.
Food allergies are caused when the immune system is
confused. The job of the immune system is to protect the body from diseases,
bacteria, viruses and germs. The antibodies produced by the immune system helps
to fight these minute external organisms which makes the person sick. But if
the body is allergic to certain food, the immune system mistakes the food to a
harmful foreign substance and takes action towards it thinking that it is
dangerous to the body. The body acts adversely, when it isn’t supposed to do
so.
When the immune system detects allergic substance, the
antibodies produce mast cells. They are a kind of immune system cell which
release a chemicals, such as histamine, in the bloodstream. These chemicals
affect the respiratory system, digestive system, nose, eyes, throat, and skin.
Initial symptoms are runny nose, tingling sensation in the lips or tongue, and
itchy skin rash like hives. The reaction can be mild to severe and depends on
every individual. The symptoms can appear right after the food is consumed or
after few hours. Other symptoms are cough, wheezing, nausea, hoarse voice,
vomiting, diarrhea, stomach ache, and throat tightness.
A sudden and harsh allergic reaction is known as
anaphylaxis. The patient encounters many problems, all at once which involve
blood vessels, the heart, digestion, breathing, and skin. The blood pressure
drops very steeply, the tongue swells and there is swelling in the breathing
tubes. Patients who have such allergic reactions should be ready to handle
emergencies. They should always carry some type of medicine which will help to
combat or reduce the adverse affect of the food.
Most of the times, it is very easy to detect the cause of
food allergy. Problems such as hives begin to surface as soon as the child eats
the substance he is allergic to. At other times, it becomes very difficult to
determine the cause of allergy. In such cases, everything should be observed
under close surveillance. Food items which are made out of many ingredients
should be thoroughly checked for the allergic cause. Most of the times,
allergies are inherited from other family members or other kids born with food
allergies. Changes in the surroundings and the body play a major role in these
kinds of cases. Some of the kids aren’t actually allergic to the food and show
only mild reaction. Like people who are lactose intolerant suffer from diarrhea
and belly pain after consuming milk and diary products. This is not an
indication that the child is allergic to milk. This reaction happens because
their body is incapable of breaking down the sugars which are found in diary
products and milk.
If the conditions are severe, a doctor should be consulted
immediately. If food allergy is diagnosed, the doctor refers to an allergy
specialist. The doctor asks questions like eating patterns, past allergic
reactions and the time period between the consumption of food and the surfacing
of the symptoms. The specialist can also ask about allergy related conditions
like asthma or eczema and whether allergic reactions are hereditary. Usually
skin test and blood test is done to test the antibodies and the reaction they
have on the skin when it is exposed to the allergic substance.
