HAE Attack Triggers
Know them to avoid attacks
Most HAE attacks occur spontaneously with no apparent reason. Some triggers have, however, been documented in studies of HAE.
Documented HAE attack triggers are:
- Minor trauma
- Illnesses such as colds and flu
There are two subtypes of HAE based on the underlying genetic defect in the control of the blood protein C1-esterase inhibitor (C1INH) – and a third type HAE with normal C1INH. These angioedemas may share many of the same attack triggers.
