Anaphylaxis is a severe form of allergic reaction that can be life-threatening. An anaphylactic response happens when the body’s immune response system overreacts to the presence of a trigger substance and treats it as a threat to the body.
A trigger substance is anything that you are allergic to, such as nuts or penicillin. This trigger substance then releases a swell of chemicals, like histamine, which swells blood vessels in the body and restricts breathing.
Anaphylaxis happens to people who have severe allergies. Allergic reactions can vary from mild symptoms to life-threatening ones like anaphylactic shock. You never really know the severity of reaction you’ll have until you come into contact with the trigger substance. This is what can make allergic reactions so dangerous.
If you believe that you’re allergic to a certain substance, you should let our clinical team know. They can advise you on alternative treatments if a specific medication isn’t suitable for you.
Global prevalence data is difficult to get, but allergy and anaphylaxis prevalence is increasing year on year. It's believed that the figures could be rising for a couple of reasons. One reason could be that we are getting better at diagnosing allergies now that they are much more common than they used to be.
Another previously held theory was that children are growing up in a more sanitary environment than they used to; and because these children aren’t being exposed to as many germs or bacteria, their immune systems aren't working as they should. However there’s a growing consensus that this probably isn’t actually the case .
