Understanding Dairy Allergy:

What is a dairy allergy?
A dairy allergy is a significant health concern characterized by the immune system's overreaction to proteins found in cow's milk. Unlike lactose intolerance, which is a reaction to a sugar in milk, a dairy allergy involves an immune response to proteins like casein and whey. When a person with a dairy allergy ingests these proteins, their immune system mistakenly identifies them as harmful invaders, leading to an allergic reaction. This condition is most commonly seen in children, but it can occur at any age.

The science behind a dairy allergy involves the production of Immunoglobulin E (IgE) antibodies by the immune system. These antibodies are designed to neutralize what the body perceives as a threat. Upon subsequent exposure to milk proteins, these IgE antibodies trigger an allergic reaction. This reaction can involve various organs in the body and manifest in numerous symptoms, which can range from mild to potentially life-threatening.

What are the symptoms of a dairy allergy?
The symptoms of a dairy allergy can vary widely in severity and may affect multiple parts of the body. Common symptoms include:
Skin reactions: These may include hives, redness, swelling, or eczema. In some cases, the skin might itch or develop rashes.
Gastrointestinal issues: Symptoms can include stomach cramps, diarrhoea, vomiting, or nausea. These occur as the body attempts to expel the offending proteins.
Respiratory problems: Some individuals may experience sneezing, a runny or stuffy nose, coughing, wheezing, or difficulty breathing, particularly if they have asthma.
Anaphylaxis: In severe cases, a dairy allergy can lead to anaphylaxis, a life-threatening reaction that can cause a drop in blood pressure, severe shortness of breath, and loss of consciousness. This requires immediate medical attention.

It is also important to note that symptoms can appear immediately or several hours after consuming dairy products. The variability and potential severity of these symptoms make understanding and managing a dairy allergy crucial for those affected.

Diagnosing Dairy Allergy: From Symptoms to Testing

How do I know if I'm allergic to dairy?
Determining if you are allergic to dairy involves observing the body's reaction after consuming dairy products and seeking professional medical advice. If you experience symptoms like hives, stomach upset, vomiting, or respiratory issues shortly after consuming dairy, it may indicate an allergy. However, these symptoms can also be related to other health issues, making it essential to consult with a healthcare professional for an accurate diagnosis.

What is the difference between lactose and dairy? Understanding the difference between lactose and dairy is crucial in distinguishing between lactose intolerance and a dairy allergy. Lactose is a sugar found in milk and dairy products. Lactose intolerance occurs when the body lacks enough lactase, the enzyme needed to break down lactose, leading to digestive symptoms like bloating, gas, and diarrhoea. On the other hand, a dairy allergy is an immune response to the proteins in milk and can lead to a range of symptoms beyond just digestive distress. Lactose intolerance is generally less severe and not life-threatening, unlike a dairy allergy, which can potentially lead to anaphylaxis.

How do I know if I am lactose intolerant or allergic to milk?
Distinguishing between lactose intolerance and a milk allergy can be challenging, as some symptoms overlap. However, the key difference lies in the nature and severity of the symptoms. Lactose intolerance typically causes digestive problems like bloating, diarrhoea, and gas, and these symptoms usually occur a few hours after consuming dairy. In contrast, a milk allergy can trigger a broader range of symptoms, including skin reactions, respiratory problems, and in severe cases, anaphylaxis. These symptoms can occur immediately or within a few hours of dairy consumption. If you're unsure, it's best to consult a healthcare professional who can conduct appropriate tests to determine the cause of your symptoms.

Can you eat lactose if you have a milk allergy?
If you have a milk allergy, it is advisable to avoid lactose and all dairy products entirely. This is because a milk allergy is a reaction to the proteins in milk, not just the lactose. Consuming lactose-free products will not prevent an allergic reaction if they contain milk proteins. Therefore, individuals with a milk allergy must read labels carefully to ensure that foods are not only lactose-free but also completely free of milk proteins.

Understanding the Onset and Testing of Dairy Allergy

What age does a dairy allergy start?
A dairy allergy can develop at any age, but it is most commonly diagnosed in infancy and early childhood. Many children are introduced to cow's milk as they wean off breast milk or formula, which is when symptoms of a dairy allergy often first appear. It's important to monitor for any adverse reactions during this transition period. However, while less common, adults can also develop a dairy allergy, even if they have previously consumed dairy products without any issues.

Can adults develop a dairy allergy?
Yes, adults can develop a dairy allergy, even if they have consumed dairy products without problems for most of their lives. This phenomenon, known as adult-onset allergy, can occur due to changes in the immune system. The reasons for these changes can be varied and are not always clear. It's important for adults who suddenly experience symptoms after consuming dairy to consult a healthcare professional, as they might be developing an allergy.

What are the first signs of being dairy intolerant?
The first signs of being dairy intolerant typically involve digestive discomfort. This can include symptoms like bloating, gas, diarrhoea, and abdominal pain. These symptoms usually occur a few hours after consuming dairy products. Unlike a dairy allergy, lactose intolerance symptoms are generally limited to the digestive system and do not involve the immune system.

How do they test for a dairy allergy?
Testing for a dairy allergy is usually done through skin prick tests or blood tests. In a skin prick test, a small amount of the allergen is placed on the skin, and the area is pricked to allow the allergen to enter the surface layer of the skin. If a wheal (a small, red, raised area) develops, it indicates an allergic reaction. Blood tests measure the level of IgE antibodies to specific allergens, including cow's milk. In some cases, an oral food challenge, supervised by a healthcare professional, may be used to confirm the diagnosis. This involves consuming small, increasing amounts of the suspected allergen to observe the body's reaction.

Managing and Treating Dairy Allergy: Lifestyle and Medical Approaches

Can a dairy allergy be cured?
Currently, there is no cure for a dairy allergy. The primary method of managing a dairy allergy is strict avoidance of dairy products. This involves carefully reading food labels, as milk proteins can be found in many processed foods. In some cases, especially in children, a dairy allergy may be outgrown with age. Regular follow-ups with a healthcare provider can help determine if the allergy is persisting.

Do antihistamines help milk allergy?
Antihistamines can help alleviate some symptoms of a milk allergy, such as hives or a runny nose, by blocking the action of histamine, a chemical released during an allergic reaction. However, antihistamines are not a cure for a milk allergy and do not prevent serious reactions like anaphylaxis. Individuals with a known milk allergy should carry an epinephrine auto-injector (if prescribed) and seek immediate medical attention if they experience a severe reaction.

Can I be allergic to milk but not cheese?
It is possible to be allergic to milk but tolerate certain types of cheese. This is because the processing of cheese can alter the proteins in a way that might not trigger an allergic reaction in some people. However, this is not a guarantee, and those with a milk allergy should consult with a healthcare provider before trying cheese or any other dairy products.

What foods should you avoid if you are allergic to dairy?
If you are allergic to dairy, you should avoid all foods containing milk and milk proteins. This includes obvious sources like milk, cheese, butter, and yogurt, as well as less obvious sources like some bread, crackers, chocolates, and processed snacks. It's crucial to read food labels carefully and look for terms like whey, casein, lactalbumin, and lactoglobulin, which indicate the presence of milk proteins.

Are eggs dairy?
Eggs are not dairy products. The term 'dairy' refers to products made from mammalian milk, such as cow, goat, or sheep milk. Eggs are laid by birds and are classified as poultry products. However, those with a dairy allergy should still read labels carefully, as some processed foods containing eggs may also contain milk products.

What happens to your body when you eliminate dairy?
Eliminating dairy from your diet, especially if you have a dairy allergy or lactose intolerance, can lead to improvements in symptoms like digestive discomfort, skin reactions, or respiratory issues. For those without allergies or intolerances, removing dairy might not have significant health effects and should be done with consideration to maintaining a balanced diet. Dairy products are a key source of calcium and vitamin D, so it's important to find alternative sources of these nutrients when eliminating dairy.
