Answer:
What Is a Milk Allergy?
When someone has a milk allergy, the body's immune system, which normally fights infections, overreacts to proteins in milk. If the person drinks or eats a product that contains milk, the body thinks these proteins are harmful invaders. The immune system responds by working very hard to fight off the invader. This causes an allergic reaction.
Milk is among the most common foods that cause allergic reactions. Some kids with a milk allergy outgrow it as they get older.
What Happens With a Milk Allergy?
People who are allergic to milk react to one or more of the proteins in it. Some people are allergic to casein (pronounced: KAY-seen) protein and some are allergic to whey (pronounced: WAY) protein. Some people are allergic to both casein and whey.
When a person with a milk allergy eats these proteins, the body releases chemicals like histamine. The release of these chemicals can cause someone to have symptoms like:
wheezing
trouble breathing
coughing
hoarseness
throat tightness
belly pain
vomiting
diarrhea
itchy, watery, or swollen eyes
hives
