How To Identify Allergies

Allergies are hypersensitive reactions by your body to some unknown allergen. The unknown allergen is termed an antigen. Allergens responsible for adult allergic reactions are termed atopic allergens. Commonly known allergens responsible for adult allergic reactions are food additives, preservatives, latex, artificial colors and flavorings, small animal fur and dander, fabrics, and solvents. Adult sensitivities to environmental substances and increased exposure to chemicals result in increased sensitivity of the upper respiratory tract and airways to particular irritants.

Allergies causing hives and swelling of the linings of the respiratory tract commonly occur with exposure to dust, mold, and cockroaches. Allergens that are responsible for causing allergies in the digestive tract are called pollens. Allergic reactions in the respiratory tract can also be caused by inhalation of animal hair and dander, mold spores, and pollen. Anti-static bags and particles trap dust mites and other microscopic allergens.
Allergies to animals are primarily associated with an atopic or nonatopic reaction. Dogs and cats are almost always included in the allergic rhinitis caused by animal dander. You should note that in the case of dogs and cats, infections can be quite serious if left untreated, and they may develop allergy-related diseases like bronchial obstructions, asthma, and skin disease.
Allergies caused by dust mites over-the-counter medications, shampoos, sprays, soaps, and detergents are usually considered mild allergic reactions. You can quickly treat mild allergic reactions with over-the-counter (OTC), prescription (Rx), and OTC medications. The most common drugs used for OTC treatments are diphenhydramine (Ditropan), hydrocortisone, iatrogenic, methylprednisolone, and prednisolone. You can purchase these medications without a prescription from pharmacies and at chain supermarkets.
Atopic dermatitis is often accompanied by a watery and itchy nose, eyes, sneezing, and red eyes. It can lead to difficulty breathing. Since allergens are trapped in the nose and throat lining, increased mucus production, coughing, runny nose, wheezing, and inflammation of the membranes near the nose and eyes can result. In some instances, a potent allergen can cause severe damage to the structures of the larynx and trachea.
Allergic rhinitis caused by allergic reactions to dust, mold, or pet dander usually affects individuals who spend a lot of time outdoors. These are the individuals who most often come into contact with dust mites or with pet dander. They experience red eyes, itchiness, and watery eyes. It is also possible for individuals with allergies to develop anaphylactic shock when exposed to dust mites. Allergic rhinitis is diagnosed as having a dust allergy. However, other sources of exposure such as bedding and household dust may also be considered as triggers.

Allergies caused by histamine are characterized by sneezing, coughing and watering eyes, wheezing, and skin irritation. Histamine is released by mast cells to counteract the effects of an allergen which can be of varying allergens. When the immune system reacts to a histamine allergen, it produces immunoglobulin, which causes the eyes to swell and produce histamine. This causes the throat to make even more mucus. These allergies are usually diagnosed when patients experience repeated bouts of sneezing, runny nose, conjunctivitis, and eye irritation.

Allergies that cause the respiratory tract to swell and cause a red-rimmed appearance, called nasal congestion, are often referred to as allergic rhinitis. This is often seen in individuals who have allergic asthma. Inhalant allergy can cause shortness of breath, rapid breathing, chest tightness, and swelling of the face, lips, tongue, and throat. An allergic reaction can also cause swelling and edema of the upper body, including the arm, shoulder, and legs. Allergic reactions are most familiar to chemicals found in antifreeze, pesticides, some cosmetics, household cleaning products, and some food.
