Hereditaryangioedema(HAE) is a rare inherited condition that causes episodes of swelling inside and outside the body.
The effects and symptoms of HAE can occur unexpectedly and with an unpredictable pattern.
Certaintriggers, such as getting a cold or experiencing stress, can also cause the symptoms to develop.

Sometimes HAE is associated with a skin rash.
If not treated, they may last up to a week.
Some people may experience more frequent and severe effects.
Others with the condition may not have as many effects.
Unpredictability of HAE symptoms
One of the hallmarks of HAE is its unpredictability.
This can start with symptoms such as difficulty swallowing and struggling to speak.
Gasping for air is a sign that a persons airway is blocked.
This is an emergency situation requiring immediate medical attention.
Keeping a symptom diary is often part of the management plan.
All of the symptoms occur when HAE causes edema (swelling) in these areas of the body.
Swelling of the throat can make it hard to breathe and can be life-threatening.
