    Allergies is a hypersensitivity disorder of the immune system.[1] Allergic reactions occur when a person's immune system reacts to normally harmless substances in the environment. A substance that causes a reaction is called an allergen. These reactions are acquired, predictable, and rapid. Allergy is one of four forms of hypersensitivity and is formally called type I (or immediate) hypersensitivity. Allergic reactions are distinctive because of excessive activation of certain white blood cells called mast cells and basophils by a type of antibody called Immunoglobulin E (IgE). This reaction results in an inflammatory response which can range from uncomfortable to dangerous.

    Mild allergies like hay fever are very common in the human population and cause symptoms such as red eyes, itchiness, and runny nose, eczema, hives, or an asthma attack. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening reactions called anaphylaxis. Food allergies, and reactions to the venom of stinging insects such as wasps and bees are often associated with these severe reactions.[2]

    A variety of tests exist to diagnose allergic conditions. These include placing possible allergens on the skin and looking for a reaction such as swelling. Blood tests can also be done to look for an allergen-specific IgE.

    Welcome to the world of allergies. There are hundreds of resources available on allergies, perhaps you’ve read a few, or perhaps this is the first book you picked up about allergies.

    If that is the case, you’ll be pleased to know we have combined our intimate knowledge of allergies as well as traditional and unconventional approaches to diagnosing, treating and preventing them in this unique, easy-to-follow guidebook.

    From the time I was a young child I suffered from allergies – hay fever was for me the worst as a child, though as I grew older I suffered from food allergies as well. A bee sting for me now leads to an anaphylactic reaction; the last time I was stung, I was in the hospital for 3 days.

    So, you might say I am intimately familiar with allergies.

    Allergies they say, tend to run in families. I believe it. Some people however, develop allergies for miscellaneous reasons. You can for example, develop allergies because of a weakened immune system, or chronic state of illness. Many times, our bodies lose the ability to fight off irritants when our immune system is not 100 percent.

    No matter the case, you will find the information in this guidebook invaluable as you navigate your way through the world of allergies. You’ll learn everything there is to know about conventional allergies (like allergies to pollen, dust and more) and food allergies.

    You’ll find out what some of the more common diagnostic tools are for measuring your sensitivity, and discover ways to avoid common triggers so you can live life as comfortably (and symptom free) as possible.

    You’ll even gain access to the single most comprehensive FAQ and resource sections available on allergies. So you can take what you learn from this book and research your own allergies even further, all by utilizing the tools provided in this guide.
    Treatments for allergies include avoiding known allergens, use of medications such as anti-histamines that specifically prevent allergic reactions, steroids that modify the immune system in general, and medications such as decongestants that reduce the symptoms. Many of these medications are taken by mouth, though epinephrine, which is used to treat anaphylactic reactions, is injected. Immunotherapy uses injected allergens to desensitize the body's response.
