Anaphylaxis Overview

Anaphylaxis is a severe allergic reaction that can affect various systems of the body. It requires immediate medical attention due to its potentially life-threatening nature and has been called the most serious form of hypersensitivity response in humans. Recognizing the signs of this condition and knowing how to respond promptly can save lives.

Symptoms of Anaphylaxis

Symptoms may appear rapidly after exposure to an allergen and typically involve multiple organ systems; however, there might also be isolated cases where only one system is affected. Common symptoms include difficulty breathing, low blood pressure, loss of consciousness, swelling of the throat, hives, nausea, vomiting, diarrhea, abdominal pain, chest tightness, dizziness, lightheadedness, unconsciousness, weakness, fatigue, anxiety, restlessness, rapid heartbeat, pale skin, cold sweat, flushing, red eyes, blurred vision, headache, inflammation of the nose lining, salivary glands, and bronchial tubes. Some patients experience these symptoms within minutes while others develop them over hours with some subsiding before more emerge.

The severity of anaphylactic reactions varies from patient to patient. For instance, two individuals exposed to peanuts could have very different responses—one experiencing mild symptoms like itching and another suffering cardiac arrest. A person who's previously had an anaphylactic reaction usually knows what their triggers are, such as penicillin or nuts, which helps them avoid those allergens.

Causes of Anaphylaxis

Certain medications can cause anaphylactic reactions., including beta lactam antibiotics (such as Penicillin), nonsteroidal antiinflammatory drugs (NSAIDs) like aspirin, anticonvulsants, monoclonal antibodies used to treat cancer, general anesthesia, radiocontrast agents, and vaccines. Other potential causes include insect bites or stings, foods (including shellfish, peanuts, tree nuts, fish, wheat, soybeans, sesame seeds, peas, and eggs). Medical conditions associated with an increased risk of anaphylaxis include asthma, hay fever, sinusitis, rhinitis, conjunctivitis, eczema, acne, bladder stones, angioderma, psoriasis, and thyroid disorders.

In summary, anaphylaxis is a severe allergic reaction characterized by symptoms affecting various parts of the body, often requiring urgent medical attention. Knowing the possible triggers and understanding the typical symptoms can help both prevent and manage future incidents.
