The immune system mistakes milk proteins like casein or whey for harmful substances, releasing histamines and such, causing symptoms. Symptoms can show up within minutes or hours after eating milk products. Immediate ones include hives, swelling, wheezing, etc. Delayed ones involve digestion or breathing problems.
In severe cases, milk allergy can cause anaphylaxis, a life – threatening reaction. Quick treatment with an epinephrine shot and a trip to the ER are crucial.
It’s important to tell a milk allergy apart from lactose intolerance or milk protein intolerance. Lactose intolerance is a digestion issue, not an immune one, with milder symptoms like bloating and gas.
Some factors make milk allergy more likely. Kids with atopic dermatitis are more prone. A family history of allergies also raises the risk. Milk allergy is common in young kids, but many outgrow it as they age.
