Allergy

Allergy This is an excessive and abnormal reaction of the immune system to substances which, in most people, do not trigger a harmful immune response. These substances are called allergens. An allergy can be chronic and cause symptoms that affect day-to-day life.

Allergy It can be triggered, amongst other things, by plant pollen, dust mites, animal hair and dander, moulds, and food components such as cow’s milk proteins, eggs, wheat or nuts. The body’s reaction depends on the type of allergen and the patient’s individual sensitivity.

Allergy symptoms They can affect various systems and occur at any age. The most common symptoms include sneezing, a runny nose, a blocked nose, watery and red eyes, a cough, wheezing and urticaria. In the case of food allergies, gastrointestinal symptoms and skin changes may also occur.

Allergy treatment This depends on the type of allergy, the severity of the symptoms and the patient’s individual circumstances. The mainstay of treatment is, where possible, to limit exposure to the allergen. Treatment includes, amongst other things, antihistamines and topical preparations, and in selected cases also allergen immunotherapy. It involves the gradual administration of carefully selected doses of the allergen in order to reduce the body’s excessive reactivity.

In the event of a severe allergic reaction, particularly if it involves difficulty breathing or swelling of the tongue or throat, urgent medical attention is required.
