anafilaxiára

Anafilaxiára is a severe, potentially life-threatening allergic reaction that occurs rapidly after exposure to an allergen. It is a systemic response, meaning it affects multiple organ systems in the body. Common triggers for anaphylaxis include certain foods like peanuts, tree nuts, shellfish, and milk, as well as insect stings, medications, and latex.

The symptoms of anaphylaxis can appear within minutes or up to an hour after exposure to the allergen. They can include itching, hives, flushing of the skin, swelling of the lips, tongue, or throat, and difficulty breathing due to airway constriction. Gastrointestinal symptoms such as nausea, vomiting, diarrhea, and abdominal cramps can also occur. Cardiovascular effects may include a drop in blood pressure, rapid heart rate, dizziness, and loss of consciousness.

Prompt recognition and treatment are crucial for managing anaphylaxis. The primary treatment is immediate administration of epinephrine (adrenaline) via an auto-injector. Epinephrine works by constricting blood vessels, opening airways, and reducing swelling. After epinephrine administration, individuals should seek immediate medical attention, even if symptoms improve, as a second wave of reaction, known as biphasic anaphylaxis, can occur.

Prevention of anaphylaxis involves strict avoidance of known allergens. Individuals diagnosed with a severe allergy are often prescribed epinephrine auto-injectors and advised to carry them at all times. Education about recognizing symptoms and using the auto-injector is essential for patients and their caregivers. Medical professionals play a key role in diagnosis, management, and providing guidance on allergen avoidance and emergency preparedness.
