Understanding Dairy Allergies
Dairy allergies are a type of food allergy that occurs when the immune system mistakenly identifies certain proteins found in dairy products as harmful. This can trigger an allergic reaction, which may range from mild to severe. In the UK, dairy allergies are relatively common among children, although some may outgrow them in later childhood. It is important to discern between a dairy allergy and lactose intolerance, as they are different conditions.
Symptoms of Dairy Allergies
Symptoms of a dairy allergy can manifest within minutes to a few hours after consuming dairy products. They often include skin reactions such as hives, itching, or eczema. Gastrointestinal symptoms, such as stomach pain, nausea, vomiting, and diarrhoea, are also common. In some cases, respiratory symptoms like wheezing, coughing, and nasal congestion may occur. In severe cases, a dairy allergy can lead to anaphylaxis, a life-threatening reaction that requires immediate medical attention.
Causes and Diagnosis
Dairy allergies are caused by an immune response to one or more proteins found in cow's milk, with casein and whey being the most common culprits. Diagnosis often involves a consultation with a healthcare professional, who may recommend skin prick tests or blood tests. An elimination diet, followed by a supervised food challenge, may also be used to confirm the allergy.
Managing Dairy Allergies
Management primarily involves strict avoidance of all dairy products and foods containing dairy ingredients. Reading food labels carefully is essential to avoid accidental exposure. It is also important to be aware of cross-contamination risks in food preparation. For those with severe allergies, doctors often prescribe an adrenaline auto-injector, such as an EpiPen, to be used in case of an emergency. Healthcare professionals or dietitians can provide guidance on alternative sources of calcium and other nutrients usually obtained from dairy foods.
Understanding Dairy Allergies
Dairy allergies happen when the body thinks the proteins in milk are bad. This makes the body react. This reaction can be small or big. Many children in the UK have dairy allergies, but some get better as they grow up. A dairy allergy is different from lactose intolerance.
Symptoms of Dairy Allergies
Symptoms can show up fast after eating or drinking milk products. Symptoms on the skin include hives, itching, or eczema. You might also have stomach pain, feel sick, throw up, or have diarrhea. Sometimes, you might have trouble breathing, like wheezing or coughing. In very serious cases, it can be life-threatening and you need to see a doctor right away.
Causes and Diagnosis
Dairy allergies are because of proteins in milk, like casein and whey. To find out if you have a dairy allergy, you need to see a doctor. The doctor might do some tests on your skin or blood. Sometimes, the doctor will ask you to stop eating certain foods to see if you feel better.
Managing Dairy Allergies
The best way to handle a dairy allergy is to stay away from milk and anything with milk in it. Always check food labels to make sure they don't have milk. Be careful when preparing food to avoid mixing milk with other foods. If your allergy is serious, a doctor might give you a special medicine called an EpiPen to use in emergencies. A healthcare worker can help you find other foods that give you calcium and nutrients without milk.
