What does anaphylaxis mean?
Anaphylaxis is a severe and potentially life-threatening allergic reaction that requires immediate medical attention. It can occur within minutes of exposure to an allergen, such as peanuts, shellfish, or certain medications. Symptoms may include difficulty breathing, rapid heartbeat, and a drop in blood pressure. If left untreated, anaphylaxis can lead to anaphylactic shock, which can be fatal. Prompt administration of epinephrine and other emergency treatments can help alleviate symptoms and prevent serious complications. Anaphylaxis is a medical emergency that should be taken seriously, and individuals with a history of allergies should be aware of the risks and take steps to prevent exposure.
