A food allergy can cause a range of symptoms, from mild to life-threatening. Common symptoms include hives, itching, swelling, gastrointestinal issues, and respiratory problems. Severe reactions, known as anaphylaxis, can lead to difficulty breathing, a drop in blood pressure, and even death if not treated promptly. It is essential for nurses to recognize these symptoms and act quickly to administer emergency treatment, such as an epinephrine injection.
