eritusreaktsioone

Eritusreaktsioone is a term used to describe adverse reactions that can occur in the body following exposure to certain substances or stimuli. These reactions are typically a manifestation of the immune system's response, although in some cases, non-immunological mechanisms may also be involved. The severity of eritusreaktsioone can range from mild, localized symptoms to severe, systemic and potentially life-threatening conditions.

Common causes of eritusreaktsioone include a wide array of substances such as medications, insect stings, foods, and environmental allergens like pollen or dust mites. The body's immune system identifies these substances as foreign or harmful and initiates a defense response. This response can involve the release of various chemical mediators, such as histamine, which lead to characteristic symptoms.

Symptoms of eritusreaktsioone are diverse and depend on the causative agent and the individual's sensitivity. They can include skin manifestations like redness, itching, hives, or swelling. Respiratory symptoms might involve sneezing, nasal congestion, coughing, or difficulty breathing. Gastrointestinal issues can present as nausea, vomiting, or diarrhea. In severe cases, anaphylaxis, a rapid and widespread allergic reaction, can occur, leading to a sudden drop in blood pressure, difficulty breathing, and loss of consciousness. Diagnosis of eritusreaktsioone often involves a medical history, physical examination, and sometimes specific allergy testing. Management focuses on avoiding the offending substance and treating the symptoms with medications such as antihistamines or corticosteroids. In emergency situations, epinephrine is administered.
