How can you recognise anaphylaxis?

There is no single set of criteria for identifying anaphylaxis, as you will not see all of the signs and symptoms in every instance, and the signs and symptoms can indicate other conditions as well. However, anaphylaxis is likely if a person develops sudden and severe problems such as life-threatening breathing difficulties and skin changes a short time (usually a few minutes) after being exposed to a certain allergen. However, 20 % of the time, skin changes do not occur, and there may be instances of anaphylaxis where the person only has problems with low blood pressure during the episode.

In instances where only swellings (urticaria / angioedema) occur throughout the body, the person affected does not have anaphylaxis, as there are no life threatening problems with the airways, breathing, or circulation.
