Hereditary angioedema (HAE), type 2 is a disease that causes sudden swelling in the body. Swelling most commonly occurs in the limbs, face, intestinal tract, and airway. Swelling typically occurs randomly, although stress and trauma could be connected to the swelling. Another symptom of this disease is a non-itchy rash that occurs during a swelling episode (called erythema). Symptoms usually begin in childhood, but the symptoms can get worse during and after puberty. Without treatment, the swelling happens about once every one to two weeks, with the worst episodes lasting three to four days. There is a wide variation in how often and how long the episodes last, even between members of the same family who have HAE.
Hereditary angioedema (HAE), type 2 can be caused by a random change in the gene, meaning that there is no family history of the disease, yet a child can still develop HAE. The second way is through inheriting the affected gene, which means a parent who has HAE can pass it down to their child. HAE can be tested for and diagnosed before birth. HAE is diagnosed through blood samples or genetic testing. Treatment involves either self-given or physician-given shots of various medications.
There are multiple treatment options to manage HAE, and you should consult a doctor about what option is right for you. If you or a family member has been diagnosed with HAEy, talk to your doctor about the most current treatment options. Support groups are also good resources for information.
