What happens during anaphylaxis?
Answer:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur within seconds or minutes of exposure to an allergen. During anaphylaxis, the immune system overreacts to a harmless substance, releasing a flood of chemicals that can cause a range of symptoms throughout the body. Some of the symptoms include:
1. Skin Reactions:
- Itching, hives, flushed or pale skin
- Swelling of the face, lips, tongue, or throat
2. Respiratory Symptoms:
- Shortness of breath, wheezing
- Swelling or tightness in the throat
- Coughing, chest tightness
3. Cardiovascular Symptoms:
- Rapid or weak pulse
- Drop in blood pressure
- Fainting, dizziness, lightheadedness
4. Gastrointestinal Symptoms:
- Nausea, vomiting, diarrhea
- Abdominal pain, cramping
In severe cases, anaphylaxis can lead to a sudden and dramatic drop in blood pressure, shock, and even death if not treated promptly. It is crucial for individuals with known severe allergies to carry an epinephrine auto-injector (EpiPen) at all times and seek immediate medical attention if they suspect anaphylaxis.
