What is Allergology?

Allergology is a branch of medicine that deals with the diagnosis, treatment, and prevention of allergies. Allergies are hypersensitivity reactions of the body to substances that are usually harmless, such as pollen, dust mites, animal fur, certain foods, or medications. An allergist is a specialist who, through appropriate tests and examinations, can identify the allergen and propose effective treatment methods.

What are the symptoms of Allergies?

The symptoms of allergies can vary and depend on the type of allergy. The most common include:

  • Skin allergies: manifest as itching, redness, rash, and sometimes swelling.
  • Respiratory allergies: characterized by sneezing, blocked nose, cough, difficulty breathing, and in severe cases, asthma attacks.
  • Food allergies: can cause nausea, vomiting, diarrhea, abdominal pain, and in extreme cases, anaphylactic reaction.
  • Drug allergies: symptoms can vary from mild skin reactions to severe anaphylactic reactions.

What do Allergy tests look like?

Allergy diagnostics can include various tests and examinations:

  • Skin tests: the most common form of allergy diagnosis, involving the application of allergenic substances to the skin and observation of the reaction.
  • Blood tests: used to detect IgE antibodies specific to certain allergens.
  • Provocation tests: involve the controlled administration of an allergen under medical supervision to see if it triggers a reaction.
  • Patch tests: mainly used to diagnose contact allergies, involve attaching patches soaked with allergens to the skin.

Treatment and prevention of allergies

The treatment of allergies depends on their type and the severity of symptoms. It may include:

  • Avoiding allergens: a key element in preventing allergic reactions.
  • Medications: antihistamines, corticosteroids, mast cell stabilizers, can be used in the form of tablets, ointments, nasal drops, or inhalers.
  • Immunotherapy: a long-term treatment method that involves gradually accustoming the body to the allergen to reduce the allergic reaction.
  • Patient education and regular follow-up visits with an allergist are important components of effective allergy treatment.
