Certain factors may increase the risk of developing a milk allergy:

  • Other allergies. Many children allergic to milk also have other allergies. Often, however, milk allergy is the first to develop.
  • Atopic dermatitis. Children who have atopic dermatitis — a common, chronic inflammation of the skin — are much more likely to develop a food allergy.
  • Family history. A person's risk of a food allergy increases if one or both parents have a food allergy or another type of allergy — such as hay fever, asthma, hives or eczema.
  • Age. Milk allergy is more common in children. As you grow older, your digestive system matures, and your body is less likely to react to milk.
