What Are Allergies?

An allergy is very simply an exaggerated immune response to something which is generally not usually dangerous. There are an assortment of various allergies that exist and they can be caused by both genetic and environmental factors. Ultimately, this is the body’s way of protecting the body much in the same way that your body protects against bacteria and viruses. When the body finds this foreign substance it in essence attacks it to keep it away from organs and other bodily systems.

An individual who experiences allergic reactions does so because their immune response is heightened to a specific substance that does not otherwise affect others in the same way. Some examples of allergic responses include hives, swelling, itching, muscle spasms, and an increase in mucus production. These symptoms come from the release of chemicals known as histamines which help to fight off the allergen.

There are several common allergens such as mold, dust, pollen, and pet dander as well as several individuals who find reactions to medications as well as different foods. Other common allergens can be found in jewelry and cosmetics and there are many who also have allergic reactions to insect bites.

Certainly, there are also several different things that cause allergic reactions that are less common. There are individuals who are allergic to the sun, those that are allergic to water, and even those who are allergic to the adhesive in Band-Aids.

Some allergies are even found to be passed down through families. For instance if someone in your family is allergic to bee stings this can increase your chance of having an allergic reaction to a bee sting as well. Allergies can also make several medical conditions such as asthma, sinus problems, and eczema even worse.

Allergies can express themselves in many different forms. Symptoms of an allergy can include any of the following: headache, hives, itchy nose, mouth, throat, or skin, stomach cramps, diarrhea, vomiting, problems breathing, itchy eyes with redness and swelling, and coughing and wheezing. Typically the determination of which symptoms present themselves usually has to do with the part of the body that is exposed to the allergen.

Tracking where an allergic reaction comes from can be a tough job. A lot of people chart any changes that they have made when an allergy presents itself while others find that it's simpler to head to an allergist and have a multitude of tests performed to let them know exactly what they are allergic to. Regardless of what you find that you are allergic to it's advisable to contact your physician to discuss your allergic reactions and the ways in which you can address any symptoms that may arise.
