Understanding Milk Allergy

A milk allergy is an immune system reaction to one or more proteins found in cow's milk. It's one of the most common food allergies, particularly among infants and young children.

Common Symptoms

Symptoms of a milk allergy can range from mild to severe and may include:

  • Skin reactions: Hives, itching, or swelling of the lips, tongue, or face.
  • Gastrointestinal issues: Nausea, vomiting, diarrhea, or abdominal pain.
  • Respiratory problems: Wheezing, coughing, or difficulty breathing.
  • Anaphylaxis: A severe, potentially life-threatening reaction that requires immediate medical attention (NHS).

Hidden Sources of Milk

Milk proteins can be present in various foods and products, sometimes unexpectedly. Common items that may contain milk include:

  • Processed meats: Sausages, hot dogs, and deli meats.
  • Baked goods: Bread, cakes, cookies, and pastries.
  • Cereals: Some breakfast cereals and granola bars.
  • Salad dressings: Cream-based dressings and sauces.
  • Medications: Certain tablets and capsules may contain lactose as a filler.

It's crucial to read food labels carefully and be aware of terms like "casein," "whey," and "lactose," which indicate the presence of milk proteins.

Diagnosis

Diagnosing a milk allergy typically involves:

  • Medical history review: Discussing symptoms and potential triggers.
  • Skin prick tests: Introducing small amounts of milk protein to observe for allergic reactions.
  • Blood tests: Measuring specific IgE antibodies to milk proteins.
  • Oral food challenges: Under medical supervision, consuming small amounts of milk to monitor for reactions.

Severity and Risk Factors

The severity of a milk allergy can vary. Some individuals may experience mild symptoms, while others could have severe reactions. Risk factors include:

  • Age: Milk allergy is more common in infants and young children.
  • Family history: A family history of allergies, asthma, or eczema increases the risk.
  • Other allergies: Having other food allergies or allergic conditions.

Treatment and Management

The primary treatment for a milk allergy is strict avoidance of milk and milk-containing products. In cases of accidental ingestion, antihistamines may be used for mild reactions, while severe reactions (anaphylaxis) require immediate administration of epinephrine and emergency medical attention.

It's essential to consult with a healthcare professional for proper diagnosis and to develop an individualized management plan (NHS).

Conclusion

A milk allergy is a serious condition that requires careful management. Being vigilant about food labels, understanding hidden sources of milk, and having an action plan for accidental exposure are vital steps in managing this allergy effectively.
