allergiaoireet

Allergiaoireet is the term used to describe the symptoms associated with allergic reactions. It encompasses a range of manifestations that occur when the immune system reacts to otherwise harmless substances, known as allergens. The specific symptoms depend on the person and the type of allergen.

Common symptoms are categorized by body system: nasal symptoms include sneezing, runny or congested nose, and itching; ocular symptoms include itchy, red, watery eyes; skin symptoms include hives, itching, eczema, or swelling; respiratory symptoms include coughing, wheeze, and shortness of breath; gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea can occur with food allergies. In rare cases, allergic reactions can progress to anaphylaxis, a life-threatening condition requiring immediate treatment.

Onset of allergiaoireet varies with exposure and allergen. Some are immediate within minutes; others develop hours later. Seasonal allergens (pollen) cause recurrent symptoms during certain times of the year, while perennial allergens (dust mites, animal dander) may cause year-round symptoms.

Diagnosis relies on medical history and physical examination, supported by tests such as skin prick tests or specific IgE blood tests. In some cases, an elimination diet or supervised oral food challenge is used.

Management focuses on avoidance of known allergens, symptom-relief medications (antihistamines, intranasal corticosteroids, decongestants, leukotriene receptor antagonists), and emergency treatment for severe reactions (epinephrine). Allergen immunotherapy may reduce sensitivity for some allergens. Regular monitoring and an individualized plan help many people manage allergiaoireet effectively.
