Raised red or pale yellow wheals, sometimes surrounded by
an inflated border on the skin might be a sign of hives food
allergy. Though hives can also develop due to non-allergic causes,
a hives skin allergy that develops in response to an allergic
reaction is more common.
Hives Allergy
Over 20% of the cases of acute hives occur in response
to eating allergenic foods, such as wheat, eggs, nuts, chocolate,
and fish. Welts of hives
food allergy vary in size and color. They are typically itchy,
burning, and painful.
Allergy and Hives
The allergic method responsible for hives involves the
release of a chemical called histamine by the mast cells. When mast
cells release histamine, it circulates in skin capillaries and the
endothelial cells, and it provokes a reaction, which results in a
leakage of liquids from the capillaries. This process
causes rashes and itchy skin.
Allergy Symptoms Hives
Due to the unique characteristics of the wheals, hives
are easy to identify optically. An urticaria doctor can determine the
causes, including determining whether the outbreak of hives is due to a
food allergy.
Allergy Hives Treatment
If your allergy hives cover a small area of the body and
cause an itchy sensation, they can be countered by taking
antihistamines. Certain antihistamines reduce the level of itching and
swelling, which provides relief to the patient.
A hives food allergy can be prevented by avoiding all
allergenic foods. However, it may take some time and trial and error to
determine which foods provoke outbreaks. It will be helpful to
keep a food diary during this time so that you can keep track of what
you have eaten when you experience a hives outbreak.
If allergy hives are accompanied by breathing
difficulty, changes in heart rate, or other symptoms of anaphylaxis,
seek medical treatment immediately.
Allergy Shots Hives
Allergy shots
hives is a form of immunotherapy for allergic disorders in which the
patient is vaccinated with
increasingly
larger doses of an allergen with the aim of inducing immunologic
tolerance.
Wheat
Allergy Hives
Some people can develop a wheat allergy, which can
result in symptoms such as hives, swelling around the mouth, and, in
extreme cases, anaphylaxis. Like all allergies, wheat allergy involves
IgE and mast cell response.
Dust
Allergy Hives
Dust mite allergens can also cause hives. Individuals
who are allergic to dust or dust mites should use hypoallergenic
mattress covers, encase bedding with protective covers, and avoid dusty
areas.
Egg Allergy Hives
Egg allergy is most commonly found in infants soon after
eating eggs for the first time. It can result in hives.
Peanut Allergy Hives
Peanut allergy can be extremely dangerous. If your child
experiences hives after eating peanuts for the first time, the next
exposure might be more drastic. Consult your doctor before allowing
your child to eat peanuts again.
