How to Recognize Allergies and Their Symptoms

Allergies are actually a mistake on the part of your body. They occur when your immune system senses that some harmless substance is a potential threat. Your immune system creates antibodies that stay aware of the allergen that you are allergic to. These antibodies can release immune system chemicals. An example is histamine. Histamine can be responsible for allergy symptoms.

Causes of Allergies

Allergy triggers include:

  • Airborne allergens – For example, pollen, mold, and animal dander.
  • Foods – You can be allergic to a variety of foods. Common ones are peanuts, shellfish, and milk.
  • Insect bites – Some people are allergic to bee stings.
  • Medicines – Penicillin is a common medication that people are allergic to.
  • Latex – This can cause skin reactions in some people.


Allergy symptoms can affect the airways, sinuses, and nasal passages. Also, they can affect your skin and digestive system. Allergic reactions can be mild to severe. A very serious and severe reaction is called anaphylaxis.

How to Tell What You Are Allergic to

The most common way that doctors detect your specific allergies is through a skin test. Your doctor will scratch your skin and apply an allergen to that location. The skin test does not work for all allergens. However, it does work for all of the major categories. By getting tested, you may avert a potentially life-threatening reaction to an allergen.

Many times, your family history is a good indicator of the kind of allergies that you will have.

Also, your doctor may ask you a battery of questions that can help determine which allergies you have. An example of a question that she might ask you is whether you have eaten anything unusual recently.

If you are suffering from allergy symptoms, then it is a good idea to consult with your doctor or allergist. Nowadays, there are many treatment options, and you don’t need to suffer from vexing symptoms.
