Anaphylaxis is a severe allergic reaction that usually occurs very quickly after exposure to a trigger that one is allergic to, such as a food or a bee sting.
It is often life threatening.
Worldwide, the rates of anaphylaxis have gradually been increasing, at the same time as recognition of allergies in general is also increasing.
An anaphylactic reaction is usually isolated, but can sometimes have a second, delayed phase of reaction (in which case it is called a “biphasic” reaction).
Because anaphylaxis is generally under recognized, and delays increase the risk for complications, today’s top five list focuses on the symptoms of anaphylaxis.
Top Five Symptoms of Anaphylaxis
- Rapid onset of symptoms after exposure Symptoms usually start within minutes to a few hours, and usually after an obvious exposure such as a bee sting or food consumption.
- Skin symptoms: About 90 percent of people will have some type of skin change, such as hives, itching, flushing, and/or swollen lips or tongue.
- Respiratory symptoms About 70 percent of people will have respiratory system changes ranging from nasal congestion to a change in voice, to shortness of breath and/or wheezing.
- Gastrointestinal symptoms About 45 percent of people will get nausea, vomiting, diarrhea, and/or abdominal pain.
- Cardiovascular symptoms: About 45 percent of people will have symptoms such as dizziness, fainting, and/or low blood pressure.
