Allergies And Their Symptoms

Allergies are the result from the overreaction by the body’s immune system when in contact with allergens, which are mainly harmless non-parasitic antigens. Allergens, for people suffering with allergies, cause hypersensitivity in the immune system. When the allergen is recognized by the immune system, histamines are created and released by the body in order to fight the allergen off.

The symptoms of allergies are due to the creation of histamines by the body. These include burning, itchy eyes, runny nose, sneezing, coughing, hives, skin rashes, headache, vomiting, cramps and diarrhea. The combination of symptoms and intensity for allergic reactions is experienced differently for each person.

Allergens come in all sizes, shapes and environments. Both environmental and genetic can be the factors of allergies. The mother usually passes inherited allergies and if both parents have allergies, there is even a greater risk to inherit them. Some of the common allergens include, pollen, dust, pet dander and mold. You can also get allergic reactions from foods, spices, insect bites, drug interactions, cosmetics and jewelry. Usually allergens are inhaled through the nose, mouth or eyes as contact is through the air.

Allergens when breathed through the nose cause an itchy nose and throat, runny nose, coughing, wheezing and mucus production. An asthmatic response can occur when inhaled into the lungs which constricts airways and increased mucus is produced in the lungs. For eye contact, allergens cause watering, swelling, itching and red eyes. Skin contact, allergens can cause rashes, dermatitis, swelling, blisters, inflammation, eczema and skin peeling. Food allergies can cause abdominal pain, nausea, bloating, hives, swelling, vomiting and diarrhea. Response to medication, such as penicillin or aspirin, or insect bites is called anaphylaxis, which produces a systematic response. There are even allergic reactions to sunlight, temperature and friction which are more rare.

Allergies are known by anyone who has experienced them, that they make an appearance out of nowhere causing symptoms quickly. More than anything, allergies are just a hassle. Allergy treatments include medication in preventing and counteracting symptoms. Some of the medications used in treating allergy symptoms include pills, sprays, drops, injections, inhalers and creams. Immediate medical attention is required for anaphylaxis and other extreme allergic reactions.
