Health and safety can change in the blink of an eye, and one of the most severe ways that can happen is through having an allergic reaction and experiencing anaphylaxis. Anaphylaxis is caused by the over-release of chemicals, specifically histamines, which force a person’s body to go into shock. There is a wide spectrum of reactions that one can have during anaphylaxis – ranging from mild to life-threatening. It’s critical that patients and providers know what to look for to identify allergic reactions and anaphylaxis and remain proactive in seeking treatment.
