What happens when you have an anaphylactic reaction?
Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock — your blood pressure drops suddenly and your airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.
What causes anaphylactic reactions?
Anaphylaxis is the result of the immune system, the body’s natural defence system, overreacting to a trigger. This is often something you’re allergic to, but not always. Common anaphylaxis triggers include: foods – including nuts, milk, fish, shellfish, eggs and some fruits.
What are the most common anaphylactic reactions to?
Anaphylaxis (an-a-fi-LAK-sis) is a serious, life-threatening allergic reaction. The most common anaphylactic reactions are to foods, insect stings, medications and latex. If you are allergic to a substance, your immune system overreacts to this allergen by releasing chemicals that cause allergy symptoms.
What is anaphylaxis an example of?
Anaphylaxis is when you get severe allergic reactions. Examples include reactions to certain foods or particular insect stings. Going into anaphylactic shock can be life-threatening. If you notice symptoms of anaphylaxis, such as having trouble breathing, use an epinephrine injector.
How do hospitals treat anaphylaxis?
In hospital
- an oxygen mask may be used to help breathing.
- fluids may be given directly into a vein to help increase blood pressure.
- additional medicines such as antihistamines and steroids may be used to help relieve symptoms.
- blood tests may be carried out to confirm anaphylaxis.
How fast does anaphylaxis happen?
It mostly occurs within 20 minutes to 2 hours after exposure to the allergen. Signs and symptoms may be mild at first, but can rapidly worsen. A small number of people suddenly develop signs and symptoms of a severe allergic reaction (anaphylaxis) without any signs of a mild to moderate allergic reaction.
