Mjäll allergi
Milk allergy is an atypical immune system response to milk and products containing milk. It's one of the most common food allergies in children. Cow's milk is the usual cause of milk allergy, but milk from sheep, goats, buffalo and other mammals also can cause a reaction. An allergic reaction usually occurs soon after you or your child consumes milk. Signs and symptoms of milk allergy range from mild to severe and can include wheezing, vomiting, hives and digestive problems.
Milk allergy can also cause anaphylaxis — a severe, life-threatening reaction. Avoiding milk and milk products is the primary treatment for milk allergy. Fortunately, most children outgrow milk allergy.
Milk allergy
Those who don't outgrow it may need to continue to avoid milk products. Milk allergy symptoms, which differ from person to person, occur a few minutes to a few hours after you or your child drinks milk or eats milk products. A true milk allergy differs from milk protein intolerance and lactose intolerance. Unlike milk allergy, intolerance doesn't involve the immune system. Milk intolerance requires different treatment from true milk allergy.
Common signs and symptoms of milk protein intolerance or lactose intolerance include digestive problems, such as bloating, gas or diarrhea, after consuming milk or products containing milk.
Milk allergy can cause anaphylaxis, a life-threatening reaction that narrows the airways and can block breathing. Milk is the third most common food — after peanuts and tree nuts — to cause anaphylaxis. If you or your child has a reaction to milk, tell your health care provider, no matter how mild the reaction. Tests can help confirm milk allergy, so you can avoid future and potentially worse reactions.
Anaphylaxis is a medical emergency and requires treatment with an epinephrine adrenaline shot EpiPen, Adrenaclick, others and a trip to the emergency room. Signs and symptoms start soon after milk consumption and can include:. See your provider or an allergist if you or your child experiences milk allergy symptoms shortly after consuming milk. If possible, see your provider during the allergic reaction to help make a diagnosis.
Seek emergency treatment if you or your child develops signs or symptoms of anaphylaxis.

All true food allergies are caused by an immune system malfunction. If you have milk allergy, your immune system identifies certain milk proteins as harmful, triggering the production of immunoglobulin E IgE antibodies to neutralize the protein allergen. The next time you come in contact with these proteins, immunoglobulin E IgE antibodies recognize them and signal your immune system to release histamine and other chemicals, causing a range of allergic signs and symptoms.
You or your child may be allergic to only one milk protein or to both. These proteins may be hard to avoid because they're also in some processed foods. And most people who react to cow's milk will react to sheep, goat and buffalo milk. A food allergen can also cause what's sometimes called a delayed food allergy. Although any food can be a trigger, milk is one of the most common. The reaction, commonly vomiting and diarrhea, usually occurs within hours after eating the trigger rather than within minutes.

Unlike some food allergies, food protein-induced enterocolitis syndrome FPIES usually resolves over time. Children who are allergic to milk are more likely to develop certain other health problems, including:. There's no sure way to prevent a food allergy, but you can prevent reactions by avoiding the food that causes them. If you know you or your child is allergic to milk, avoid milk and milk products.
Read food labels carefully.
