Allergies (Allergology)

An allergy is an excessive reaction of the immune system to foreign, actually harmless substances, the so-called allergens. Allergic reactions can appear in very different ways and affect all organs. In our outpatient clinic, the entire spectrum of allergy diagnostics and allergy treatment for children is covered (a detailed list can be found here). Hyposensitization is carried out on an outpatient basis and, in the case of bee or wasp venom allergies, also on an inpatient basis. A specialized nutritionist is available. We treat children and adolescents between the ages of 0-18 years.
