Don’t miss what’s next in HAE
For people with HAE Life can be filled with burden
HAE attacks are often disfiguring and debilitating, imposing a significant burden on people’s quality of life
For people with HAE, attacks can affect life in many ways
Emotional burden
How it may feel:
- Some people with HAE may potentially experience near-constant anxiety about their next attack, causing them to cancel plans
- They may experience embarrassment and/or feelings of shame in front of friends, co-workers, or strangers
So if I’m swelling, emotions are heightened, absolutely. There is a sense of panic that occurs during a swell.
Today’s HAE management may come with trade-offs

I’m definitely figuring out my own personal triggers. I know that different hormones will trigger my attacks, so we have to be careful, especially when I was doing IVF. We had to take into consideration the estrogen I was exposed to.

WOMEN AND HAE
The burden of HAE is higher in women, particularly those of childbearing age

Women may be more affected by HAE due to increased estrogen levels and hormonal changes
Adolescents with menstrual disorders are sometimes prescribed oral birth control pills, which can trigger an HAE attack
Changes in female sex hormones—such as those that occur during puberty, menstruation, use of birth control pills, pregnancy, and menopause—can all affect the frequency and severity of HAE attacks
Family planning decisions may be complicated by the impact of certain treatment options

Adolescents and HAE A challenging time of life made harder by this unpredictable, disfiguring disease

While the experiences of adults and adolescents with HAE are similar in many ways, there are also unique aspects of being an adolescent with HAE, particularly the impact on schooling as well as social and emotional functioning:
- Signs of HAE usually appear when people are young, either in childhood or as a teenager
- Attacks may become more frequent and severe during and after puberty
In a study of adolescents aged 12 to 17 with HAE:
- Some reported feeling different from their peers and said they had missed childhood events such as sleepovers, parties, and spending time with friends
- HAE attacks caused them to withdraw socially, isolating themselves to avoid potential attacks, or avoiding being seen if they were experiencing swells
- Some reported feeling self-conscious and experiencing episodes of bullying or teasing due to being different or having a visible swell
Sharing information about HAE
Because HAE is so rare, many people have never heard of it— that means your friends and family may not know the basics.
10 facts about HAE
you can share with the people in your life
01
HAE is a rare disease that causes parts of my body to suddenly swell up
02
These attacks can affect different parts of my body, including my face, arms, hands, legs, feet, genitals, or stomach
03
If an attack affects my throat and prevents me from breathing, it can be life-threatening
04
These attacks may be caused by anxiety, injury, surgical procedures, or other reasons. Attacks can even happen from happy excitement, like a wedding or birthday party. Sometimes, the attacks happen for no known reason
05
About two people in 100,000 have HAE in the United States
06
There are about 7,000 people living with HAE in the United States
07
HAE is typically passed down from parent to child
08
HAE is not contagious, and I cannot pass it on to you
09
The attack from HAE is not the same as swelling from an allergic reaction
10
The medications that treat allergic reactions are not effective in treating an HAE attack. One way of treating an attack is to give myself an injection of a medication prescribed by my healthcare provider
Questions to Ask Your Healthcare provider
It can be helpful to take a list of questions to your healthcare provider’s appointment, so you remember everything you want to discuss. The following are some questions you may want to ask.
- What type of HAE do I have?
- How can I avoid having an attack?
- How can I tell when the worst part of the attack has passed?
- What are the chances that I will pass this on to my children?
- Which treatment is right for me?
- Does it matter if I skip a treatment?
- I am experiencing side effects. How can I manage them?
- Are there any current clinical trials, and can I participate?

Tracking your HAE attacks may help you find patterns over time or notice any sudden changes. After you’ve had an attack and treated it, write down the details in a journal. Recording and sharing details of your attacks may allow for improved discussion with your healthcare provider at your next visit.
- Date of attack
- Location of swelling (hands, feet, stomach, face, etc)
- Time and place symptoms began
- Type of trigger (if known)
- Attack intensity (low, medium, high)
- Was this attack similar to or different from past attacks?
- How long did the attack last?
