How does HAE
How female hormones play a role
Fluctuations in the female hormone
Estrogens are female sex hormones. They're important for sexual and reproductive development. Estrogens can also be included in oral contraceptives, hormone replacement therapy and other medications. Studies have shown that fluctuations in estrogen may influence HAE attacks in some people. can have an influence on HAE symptoms. Hormonal changes and fluctuations in sex hormones can trigger swelling attacks and affect the course of angioedema in women with HAE.
However, every woman is different, so some women with HAE may be more or less sensitive to changes in their hormone levels than others. If you have HAE, it's a good idea to work closely with your treatment specialist as you approach each life stage.
When puberty begins, the body starts to produce more hormones, including estrogen. Because estrogen may affect HAE symptoms, some females with HAE may experience their first HAE attack at this time, or they may begin to experience more frequent and more severe HAE attacks.
If you have HAE, make sure you discuss any medication you take with your doctor. Birth control pills may contain estrogen, which may affect HAE symptoms, so they could cause more frequent or severe HAE attacks.
Also note that HAE can be passed from parent to child. If one parent has HAE, there is a 50% chance it will be passed to the child. Curious about how genetics can play a role in HAE? Learn more about family and HAE.
If you're thinking about having children, you might be happy to know that women with HAE are not at an increased risk of infertility or miscarriage. During pregnancy, women with HAE may or may not see their symptoms change.
Effects of pregnancy on HAE symptoms*

During menopause, women experience another change in hormone levels that may affect HAE symptoms. Hormone replacement therapy may also affect the frequency and severity of your HAE attacks.

Early one morning, I got a call from my sister. She said, 'I know what we have.' I immediately scheduled an appointment with an HAE specialist in my area and got a diagnosis of my own within 2 months.

What are the different types of hereditary angioedema (HAE)?
There are three types of HAE, and they are classified by what problem the genetic defect causes. A person can have low levels of C1-INH in the body (type I HAE), poorly functioning C1-INH (type II HAE), or HAE with normal functioning C1-INH (HAE with Normal C1).Learn more about the types.
