Milk allergy is distinct from lactose intolerance, which is a nonallergic food sensitivity caused by the lack of the enzyme lactase in the small intestines to break lactose down into glucose and galactose.

A food intolerance differs from a food allergy or chemical sensitivity because it generally requires a normal serving size to produce symptoms similar to an IgE immunologic response. While food intolerances may be mistaken for a food allergy, they are thought to originate in the gastrointestinal system.
Symptoms of food intolerance vary greatly, and can be mistaken for the symptoms of a food allergy. While true allergies are associated with fast-acting immunoglobulin IgE responses, it can be difficult to determine the offending food causing a food intolerance because the response generally takes place over a prolonged period of time.
