Answer:
Anaphylaxis
Step-by-step explanation:
Anaphylaxis is the life-threatening condition that follows an allergic reaction to a substance that the patient's immune system is particularly sensitive to -- which substance that may be varies from person to person, be it bee venom, peanuts, seafood, certain fruit, medications, latex, eggs, etc.
During anaphylaxis, the patient's body is thrust into a shock state, causing:
- their airways to close due to the bronchial tissue within the throat swelling which limits their ability to breathe;
- their eyes swell leading to vision problems; their blood pressure may suddenly decline (hypotension);
- their heart rate may skyrocket (tachycardia); and they may experience a syncopal episode (passing out, fainting).
- If unresolved, these patients can die from such a reaction, which is why anaphylaxis can be a medical emergency.
In some cases, this condition can be temporarily resolved with the injection of the medication epinephrine, known by its brand name EpiPen or the more cost-effective alternative AdrenaClick, or colloquially as adrenaline. The administration of this medication should be promptly followed up with a visit to an emergency room (ER) for a workup by a healthcare professional.
To summarize, the life-threatening allergic reaction to a substance, like peanuts, is known as anaphylaxis.
