Q: Can a person develop a milk allergy and what are the symptoms?
Dr. Paul Lenkowski with Jefferson Surgical Clinic gives us the facts on this one:
Yes, but usually you develop this allergy as an infant and outgrow it by your teen years. It is uncommon to develop this allergy in adult life but you certainly can have a milk allergy that carries on from infancy.
Yes, milk allergy can cause gastrointestinal symptoms like cramping, bloating, diarrhea, even blood in the stool, nausea, abdominal pain, diarrhea; typically in conjunction with cutaneous and/or respiratory symptoms.
You can even develop an anaphylaxis reaction to food allergens similar to that of a peanut allergy, but this is less common. More often GI upset from milk comes from Lactose intolerance which is an enzyme problem more than an allergy.
