Types of allergies and reactions
There are three main types of allergies, environmental (grasses, cat & dogs,trees) causing an inflamation in the nose and throat membrane. Food allergy (milk nuts many more) immune system reaction, various responses. Drug Allergy (penicillin) reactions can vary from rashes to anaphylaxis.
Anaphylaxis is a severe, allergic reaction that can be life threatenning. During this type of reaction there is a drop in blood presure narrowing or closer of airways and is often fatal unless immediate treatment is given.
Other allergic reactions include, rashes, and diareah. Sometimes children with milk allergy are diagnosed with "failure to thrive" due to lack of weight gain, or even weight loss.
A food allergy is an inappropriate immune system responce. A food intolerance causes abnormal discomfort and indigestion but not a reaction in the immune system. The level of discomfort a person can have with both food intolerance and food allergy, can differ greatly.
Allergic tendencies can be inherited. Enviromental conditions can effect the chances of someone developing allergies. Prolonged breastfeeding and delaying the introduction of solid foods can reduce the chances of developing allergies in later life. There is research that suggests exposure to dirt during a childs early years, can reduce the chances of developing allergies. By excerising the early immune system.
Reactions to milk
Allergic reactions can occer to different milk proteins,lactalbumin, lactogloblin and caisein, as well as whey (a byproduct) The protein caisein, is most often the most allergic component, is used often as a binding agent in food and other products.
Boiling, heating milk will reduce the allergenicity of whey but will not effect the reactions to the milk protein casein.
Lactose, is the sugar in milk, and is often used as a filler in many drugs, and even some sunscreens. Even if you have the enzymes to digest the lactose, the lactose can still have some milk protein in it.
Lactose Intolerance is a lack of the enzyme lactase, to digest the sugar in cows milk called lactose. Even lactose free milk has some lactose in it. Removing the lactose from milk does nothing to remove the proteins from milk. Just like sugar free peanutbutter, would be a problem to a person who is allergic to peanuts a lactose free milk would be a problem to someone who is allergic to milk.
About milk uses
Mammailian milks, That humans have used for food, include milk from many animals, other than human milk, samples include cow, camel, goat or yak. Most people who are allergic to cow's also have an allergy to goat.
Whey is a by-product of the cheese making process. This by product is difficult to dispose of in an enviromentaly friendly way, so they use it in many pet and people food.
Testing for allergies
Durring a skin test the skin is pricked with allergyns to see if reaction occers on skin.
Blood tests can also be given called R.A.S.P (Rasio-Allergo-Sorbent) measures levels of
antibodies to allergens.
A chalange test is when a patient is given orally, first small amounts of allergyn, UNDER MEDICAL SUPERVISION to see if reaction occers. Chalange tests are rarely done now, for people with severe reations.
