Risk factors
By Mayo Clinic staffThere aren't many known risk factors for anaphylaxis, but some things that may increase your risk include:
- A personal history of anaphylaxis. If you've experienced anaphylaxis once, your risk of having this serious reaction is increased. Future reactions may be more severe than the first reaction.
- Allergies or asthma. People who have either condition are at increased risk of having anaphylaxis.
- A family history. If you have family members who have experienced exercised-induced anaphylaxis, your risk of developing this type of anaphylaxis is higher than it is for someone without a family history.
