welche allergien gibt es — when to see a doctor?

Allergies are broadly categorized into food allergies (peanuts, milk, eggs, wheat, soy, fish, shellfish), inhalant allergies (pollen, dust mites, mold, pet dander), insect venom allergies (bees, wasps), and contact allergies (nickel, fragrances, latex). Drug allergies are also common. When to see a doctor? If you experience recurrent or bothersome symptoms such as sneezing, runny nose, itchy eyes, skin rash, diarrhea, or shortness of breath after exposure to a suspected trigger. Especially for signs of anaphylaxis (swelling, difficulty breathing, dizziness), seek emergency care immediately. Allergy testing (skin prick, specific IgE) should be guided by a physician after a thorough history. Evidence for direct-to-consumer allergy tests is weak; they often yield false positives. The provided context lacks specific allergy information, so this answer is based on general medical practice. Note: Extra caution is needed for children and pregnant individuals.
