Allergy symptoms start out mild often. The condition can cause the eyes to water, itch, or can cause the nose to drip mucus. The skin sometimes is irritated, which causes itchy or hives. Sometimes hives can cause the skin to swell. In some instances, angioedema causes swelling in the larger areas of the skin.
How does swelling occur?
When the blood vessels start leaking fluids, it can cause swelling. In some instances, angioedema can develop into a serious condition. Serious conditions may start the reaction that emerges from asthmatic conditions.
How do these allergies affect me?
In some instances when “anaphylactic reactions” occur, the allergies can take a life. In this life-threatening instance wheezing develops, which emerges from constricting airways. The blood pressure can lower, especially if the blood vessels start to open and dilate.
How is this condition diagnosed?
First, doctors will consider the symptoms. The doctor will consider hereditary factors before diagnosing this type of allergy. Eosinophilis is a white blood cell, which doctors evaluate through blood test. If an allergic reaction causes a large count of eosinophilis to produce, it is a sign that the patient has such allergies.
Allergens often trigger allergy reactions. Doctors will consider these allergens, which they examine dust mites, pollen, dust, mold, pet dander and so forth. Hereditary allergens are examined also.
How can I help the doctor find a diagnosis?
You can recount the time your allergies first started. The start date can help the doctor decide what type of allergens is causing you irritation. If your allergies start in September and carry on to October likely, you have seasonal allergic reactions. Most times the diagnosis is hay fever, yet in some instances the symptoms decide otherwise.
Doctors will need to know how frequent your symptoms occur. This will help the doctor find a diagnostic. The doctor bases the diagnostic on foods you eat, season and so on.
Doctors will also use skin tests to find allergen reactions. Generally, skin tests assist doctors in finding diagnostics quickly. Doctors will use needles and prick the skin in several areas, and sometimes over hundreds of times to find the cause.
Doctors will use the needles, which have diluted solutions to test for allergies. The solutions may include medicinal ingredients, food, dander from pets, pollen, fungal spores, venom from insects, weeds, grass, trees and so on. Some trees are made of latex materials, which if the skin shows a reaction from this extract, likely the patient has allergies that stem from latex.
In this case, the doctor will direct the patient to avoid foods, latex and other allergens that cause a reaction. The doctor will then treat the patient with shots or other remedies to help control the symptoms.
How can the doctor tell if a reaction occurs?
Doctors look for reactions, such as swelling, paleness, wheal, and so on. If a wheal appears often swelling and redness develops in a few minutes.
Will the doctor inject the solutions into the flesh?
Yes, if it seems no reaction occurs the doctor will use injection methods to discover potential allergic reactions.
What if the doctor cannot discover allergen reactions in skin tests?
If the doctor does not find anything, then likely other tests are needed to discover allergies. In some instances, other tests are needed when a person reacts with harsh red rashes to pricks or injections. In this instance, the doctor will perform a RAST test, or Radioallergosorbent test.
For the most part doctors find allergen reactions when using skin tests and in most instances, allergies are curable providing the patient seeks medical help immediately.
