Types of Allergies


There are various kinds of Allergies and classifying them all in one lot is confusing. Every single allergic reaction has unique symptoms and the intensity may differ with every person. It's a common belief that allergy symptoms are mere sensitivity to allergens. Additionally they believe it would be cured easily, giving proper treatment. One must understand, mere sensitivity isn't dangerous, while allergies could be life-threatening at times. Based on the allergens, allergies are classified as follows:

Food Allergies: Very often, people confuse themselves between food intolerance and food poisoning with food allergies. Food intolerance usually causes symptoms in the digestive tract like diarrhea, nausea or abdominal pain. Sensitivity to caffeine and intolerance to lactose are some common examples of food intolerance. As the symptoms of these intolerance, aren't associated with immune system, these must not be mixed up with food allergies. Also food poisoning is a reaction, which occurs when degraded or uncooked(partially cooked) food is ingested. Also, if taken the next time there will not be any reactions. On the contrary, food allergies are caused due to allergens in the food. They react exactly the same and mostly with increased intensity each time taken. Moreover it can cause dreadful anaphylaxis with repeated intake. It's when, the immune system is severely attacked in response to allergens. Some of the common allergens are cow's milk, wheat, peanuts, eggs, shell fish, fish etc.

Medication Allergies: After consuming drugs, it is very important to examine the reaction. The physicians will be very concerned about the reactions connected with medications, as they may become life threatening in some cases. Cephalosporin, penicillin or sulfa drugs are most commonly associated with anaphylaxis. Here too, medication adverse reactions are often mistaken for allergies. Adverse reactions do not make you vulnerable to anaphylaxis. So when you're explaining the reactions to a medication to the physician, he will particularly ask you about the symptoms. They will determine whether or not to continue the medication again, depending on your description.

Insect Venom Allergies: Some people have allergies to insect bite or sting. The venom injected into their skin can cause more severe allergies. Reactions to stings of hornet, bee and wasp may be fatal. Irrespective of whether you are allergic to insect venom or not, once the insect attacks you, you will notice a rash at the bitten site. As soon as you experience a reaction consult a physician to make sure that you are allergic or not to insect bite. When you have an allergy, prompt medical attention is required to avoid the condition becoming worse.

Environmental allergies: The allergies that come from pollen, mold, dust mite deposit etc are called environmental allergies. Asthma, allergic rhinitis and atopic dermatitis are the common reactions in response to these allergens. As soon as you understand you are allergic any of the above listed allergen, consult your physician. He can assist you on avoiding or minimizing the effects and strategies for prevention in future.
