Anaphylaxis Definition: What is Anaphylaxis?

Severe Allergic Reactions (Anaphylaxis)

anaphylaxis definition

Anaphylaxis is an emergency when someone has an allergic reaction that causes their airways to close up. What happens is that the allergy causes your immune system to release chemicals called histamines to react against the allergen. This allergic reaction may represent mild symptoms of itchy skin, runny eyes and nose. However, a severe allergic reaction often result in symptoms of difficulty in breathing, swallowing, wheezing, and breathlessness due to swelling of the airways; eventually, the person loses consciousness and stops breathing.

What is Anaphylaxis?

Anyone can experience an allergic reaction, but it's hazardous for those with severe allergies. Anaphylaxis is an anaphylactic reaction that can be life-threatening and can occur instantly. If you experience any signs or symptoms of an Anaphylactic reaction, seek medical attention immediately. Symptoms of Anaphylaxis can include trouble breathing, dizziness, and shock. It is crucial to understand what Anaphylaxis involves and how to treat it. The emergency medicine, Epinephrine (adrenaline), boosts the body's immune system to fight off the allergy attack.

Signs and Symptoms of Anaphylaxis

Suppose you or a loved one experiences any of the following symptoms of Anaphylaxis. In that case, it's time to seek medical attention: swelling around the mouth or throat, shortness of breath, difficulty breathing, chest pain, and red eyes. You must immediately get to an emergency room if you notice these symptoms. With the help of an allergy specialist, you may be able to get treatment and prevent Anaphylaxis from turning into an even worse situation. Remember, Anaphylaxis is a life-threatening allergic reaction and is not something to take lightly. Watch for the symptoms and take appropriate action if you experience them.

What causes Anaphylaxis?

Anaphylaxis is a severe allergic reaction that can occur very quickly. Symptoms of Anaphylaxis include difficulty breathing, pale skin, and a fast heart rate. It can be life-threatening if not treated immediately. Most often, foods or medications trigger the symptoms of Anaphylaxis—however, it can also be brought about by other things, such as wasp or insect stings or latex allergies. Antibiotics can cause allergic reactions that can lead to Anaphylaxis. Shellfish is another common cause of severe reactions presenting in a medical emergency. Although there is no one cause of Anaphylaxis, it can happen due to many different things. Knowing the allergy symptoms and triggers helps you avoid them in the first place and get help if an allergy occurs accidentally.

Does pollen cause anaphylaxis?

Anyone who enjoys going outside should know Anaphylaxis's symptoms, ranging from mild to life-threatening. If you have been prescribed by your doctor to use an epinephrine autoinjector for, e.g., EpiPen, remember to always carry it with you in an emergency! Pollen can trigger allergic reactions even if you have never had a response before. If you are at risk for severe allergies to certain types of pollen, then keep this in mind when heading out into nature. Knowing how allergies work is the first step to avoiding them altogether!
