Allergy types

  1. 1. Allergy TypesWhy is knowledge about allergy types so important?Why such a fuss around allergies? Who cares if you sneeze a little during the spring?Well, the truth is far more unpleasant.Some statistics for you:1. Presence of asthma has increased for unbelievable 50% every 10 years forthe past 40 years.2. In States alone, researchers estimate that over 20 million on Americans haveasthma.3. 150 to 200 people die in the States every year because of the food allergies.4. At least 40 deaths per year occur because of the insect venom.5. More than 400 people die every year due to the penicillin anaphylaxis.6. There are rough estimates that allergies cost health care system over $8billion in States alone.7. There is a 33% chance that a child will develop allergies if one of his parentshave one.Do you still believe that allergies are to be taken lightly?We have made a general list on this website of different allergy types with somefurther reading. This list is by far complete and we will be adding information’s onregular basis.Food AllergiesStatistics show that 90% of allergic responses to foods are caused by milk, peanuts,eggs, tree nuts (like almonds or walnuts), fish (like flounder), shellfish (like shrimp orlobster), soy and wheat. These ingredients must be also listed on food labels (FDArequires it!). Probably the most common food allergy in States is a sensitivity tocrustacea.Milk Allergy
  2. 2. Milk allergies are by far the most common in children. This can result in intolerance tomilk from cows, goats, or sheep, or even to dairy products such as cheese.Egg AllergyEgg allergy is the second most common food allergy in children. It is basically anoversensitivity to dietary substances from the yolk of eggs and may causeoverreaction of the immune system. Usually it is treated with an exclusion diet andavoidance of foods that may have egg included.Most children outgrow egg allergy by the age of five but some of them will never.Usually we made diagnosis with the combination of skin prick testing and bloodtesting. At this point there is no cure for this allergy.Wheat AllergyDetermining if you have a wheat allergy, can be quite challenging since Omega-5gliadin that is the most potent allergen in the wheat, cannot be detected in wholewheat preparations, but it must be extracted and partially digested to reach fullactivity and therefore certain allergy tests may not be suitable to detect all kinds ofwheat allergies. On the positive side, wheat allergy is really rare kind of allergy.Peanut AllergyAlthough all allergies should be taken seriously, peanut allergy is one of those thatwe should taken extremely seriously, since it is one of the most common causes offood allergy deaths in States.By definition it is a type of food allergy that is distinct from nut allergies. This allergy isusually treated with an exclusion diet and vigilant avoidance of foods.If the worst scenario comes (anaphylaxis), person should be treated immediately withepinephrine.Fish AllergyFish can cause severe allergic reactions (such as anaphylaxis) and we advice allpeople that suffer from fish allergy to have a quick access to an epinephrine auto-injector (such as an EpiPen®) at all times.These kind of allergies are usually treated with an exclusion diet and avoidance offoods that may be contaminated with fish ingredients and/or oils.
  3. 3. This allergy usually is lifelong and statistics show that approximately 40 percent ofpeople with fish allergy experienced their first allergic reaction as adults.Shellfish AllergyShellfish allergies are very much alike fish allergies. Most of them are caused byshrimp, crab and lobster (or common name crustacea). Reactions to crustaceanshellfish tend to be much more severe than from mollusks (such as clams, musselsor oysters).To prevent a serious reaction, avoid any shellfish and shellfish products and alwaysread ingredient labels to identify shellfish ingredients.Sulfite AllergySulfites are preservatives used in various foods and medications and have beenused for centuries, mainly as food additives, but can also occur naturally in foodssuch as fermented beverages.The FDA estimates that one out of 100 people is sensitive to the sulfite compounds.A person can develop sensitivity to sulfites at any time in life.The only way to prevent reaction is to avoid foods that contain or are likely to containsulfites. Be sure to read the labels on all food items!Soy AllergySoy allergy is one of the more common food allergies that occur among babies andchildren. Many research show that an allergy to soy generally occurs childhood andoften is outgrown by age three.Allergic reactions to soy are generally mild, but in rare occasions severe reactionscan occur.Interesting fact is that the FDA exempts highly refined soybean oil from being labeledas an allergen, because studies show most individuals with a soy allergy can safelyeat soy oil that has been highly refined.But keep in mind that if you are allergic to soy, ask your doctor whether or not youshould avoid soy oil.
  4. 4. Seasonal AllergiesSpring AllergiesAs the trees start to bloom and the pollen gets airborne, allergy sufferers begin theirannual ritual of sniffling and sneezing (but this might evolve into more seriouscondition, so it shouldn’t be taken lightly).Allergy symptoms tend to be high on breezy days when the wind picks up pollen andcarries it through the air. On other hand, rainy days cause a drop in the pollen countsbecause the rain washes away the allergens.Summer AllergiesThe biggest summer allergy in the summer is pollen which can trigger the runnynose, itchy eyes, and other allergy symptoms.On other hand, one of the most common allergies in summer is ragweed (August),which can travel airborne for hundreds of miles.Fall AllergiesFall allergies are much alike summer one with ragweed and pollen as allergensprevailing.Winter AllergiesIn winter the situation is a bit different, because we can easily mix cold and allergy.The difference is usually in the time period, when colds go away much faster (usuallyin a week time).There are also different allergens from the Summer or Autumn like pet dander, moldor damp wood.Pet AllergiesDog AllergyIf you suspect you have a dog allergy, you should have symptoms likecoughing/wheezing, itchy eyes, stuffy nose or sneezing. Dog allergy can givesomeone a skin reaction and should be treated seriously with people who haveasthma.
  5. 5. If you are diagnosed with dog allergy, your doctor might subscribe you drugs likeantihistamines or decongestants.Cat AllergyCat allergy is an allergic reaction to allergens produced by cats and can resolve insymptoms like itchy eyes, itchy nose, sneezing, sore throat etc. Symptoms are oftenmistaken for a common cold.Tip: If you regularly bath your cat, you may remove significant amounts of allergensfrom the fur.Like in dog allergy, antihistamines and decongestants may provide allergy relief hereas well.Other AllergiesHay FeverHay fever (or allergic rhinitis), is a condition that shows signs and symptoms similarto a cold (sneezing, congestion, runny nose and sinus pressures). It is caused by anallergic response to airborne substances, such as pollen – unlike a cold (caused by avirus).Interesting thing about the terminology is that hay fever does not mean that theperson is allergic to hay and has a fever.Allergic Conjunctivitis (Pink Eye)Conjunctivitis (pink or madras eye) is inflammation of the outermost layer of the eyeand the inner surface of the eyelids and it is most commonly due to a viral infection oran allergic reaction.The symptoms are red eye, swelling of conjunctiva and watering of the eyes.The most effective prevention is hygiene and not rubbing the eyes by infected hands.Conjunctivitis resolves in most of the cases without treatment, within two to five days.Allergies to Poison IvyPoison ivy (also known as Toxicodendron radicans) is a poisonous North Americanplant that is well known for its production of urushiol that causes an itching, irritationand sometimes painful rash in most people who touch it.
  6. 6. The allergic reaction to it is called the Urushiol-induced contact dermatitis and can inextreme cases lead to anaphylaxis.Over 350,000 people are affected by poison ivy annually in the US.Allergies to Insect Stings (Bee Stings)Insect sting allergy is the term commonly given to the allergic response of an animalin response to the bite (or sting) of an insect.In the United States approximately 40 people die each year from anaphylaxis due tostinging insect allergy.Read more about insect sting allergy on Wikipedia.Mold AllergyBy the definition, the mold allergy occur when your immune system overreacts whenyou breathe in mold spores.Symptoms can be irritations of the eye, nose and throat, sinus congestion, and otherrespiratory problems. You should know that mold spores won’t cause asthma forexample, but it will irritate existing conditions.The best way to minimize the risk is to reduce your exposure to the mold.Pollen AllergiesOver 40 million people from States suffer from pollen allergies (when you inhale it),known as hay fever, allergic rhinitis or seasonal allergies which can range fromannoying like sneezing, itchy throat, cough, to life-threatening.Sun Reactions of the SkinSun allergy is a number of conditions in which an itchy red rash occurs on skin that’sbeen exposed to sun. The most common form of sun allergy is polymorphic lighteruption, also known as sun poisoning.Mild cases of sun allergy may resolve without treatment. More severe cases mayrequire steroid creams or pills. People who have a severe sun allergy may need totake preventative measures (wear sun-protective clothing).
  7. 7. Aspirin Allergy (Salicylate Allergy)Aspirin is a non-steroidal anti-inflammatory drug that is commonly used to recoverfrom headaches and fevers.An aspirin allergy can cause symptoms that range from mild to severe and reactionsmay include hives, itchy skin, red eyes or in a rare case – anaphylaxis (life-threatening allergic reaction).Penicillin AllergyPenicillin allergy is an overreaction by your immune system to penicillin. If you have apenicillin allergy, your reaction to taking the antibiotic may range from a rash toanaphylaxis.Although penicillin is still the most commonly reported allergy, less than 20% of allpatients that believe that they have a penicillin allergy are truly allergic to penicillin;nevertheless, penicillin is still the most common cause of severe allergic drugreactions.Read more:
