Hereditary Angioedema (HAE) Evaluation & Treatment
Hereditary angioedema (HAE) is a rare genetic condition that causes episodes of deep swelling in the skin and tissues. Swelling attacks can affect the hands, feet, face, abdomen, and airway, and symptoms may be painful, unpredictable, and potentially life-threatening. At Allergy & Asthma Specialist of the Palm Beaches, we provide expert evaluation and personalized treatment plans for hereditary angioedema to support long-term control, symptom relief, and patient safety.
What Is Hereditary Angioedema (HAE)?
Hereditary angioedema is an inherited disorder that affects the body’s ability to regulate swelling. Unlike typical allergic swelling, HAE attacks are not caused by histamine and usually do not respond to standard allergy medications.
HAE may cause:
- Recurrent swelling episodes
- Abdominal pain attacks
- Swelling in the airway (medical emergency)
Because HAE is rare and symptoms can mimic other conditions, accurate diagnosis is essential.
Symptoms of Hereditary Angioedema
Symptoms can vary by patient and attack type. Common HAE symptoms include:
- Swelling of the hands or feet
- Facial swelling (lips, eyelids)
- Swelling in the arms or legs
- Abdominal swelling causing pain, nausea, vomiting, or diarrhea
- Tightness in the throat or difficulty breathing (emergency)
HAE swelling often develops gradually over hours and may last for days without proper treatment.
HAE vs. Allergic Angioedema
Many patients with hereditary angioedema are initially misdiagnosed as having allergic reactions. However, HAE differs in important ways:
Hereditary angioedema:
- Typically does not involve hives
- Often does not involve itching
- May not improve with antihistamines or steroids
- Can cause severe abdominal attacks
- May be triggered by stress, illness, or trauma
Because treatment differs significantly, identifying HAE correctly is critical.
What Triggers HAE Attacks?
HAE attacks can occur without warning, but some common triggers include:
- Physical stress or emotional stress
- Illness or infection
- Dental procedures
- Surgery or trauma
- Certain medications
- Hormonal changes
Understanding personal triggers is an important part of managing hereditary angioedema.
Diagnosis & Evaluation for Hereditary Angioedema
Diagnosing hereditary angioedema requires a careful clinical evaluation and appropriate testing. Our team reviews:
- Symptom history and swelling patterns
- Family history of swelling disorders
- Past treatment response (including lack of response to allergy medications)
When appropriate, we may recommend testing to confirm diagnosis and determine the best management plan.
Hereditary Angioedema Treatment Options
HAE treatment focuses on preventing attacks, reducing severity, and improving long-term safety. Treatment plans are individualized based on:
- Attack frequency
- Attack severity
- Location of swelling episodes
- Lifestyle factors and triggers
Management may include:
- Long-term control strategies
- Prevention planning
- Emergency preparedness guidance
- Ongoing monitoring and follow-up
Our goal is to help patients live with greater confidence and fewer disruptions.
Why Hereditary Angioedema Treatment Matters
Without proper diagnosis and management, hereditary angioedema can lead to:
- Frequent painful swelling episodes
- Emergency visits due to severe attacks
- Dangerous airway swelling
- Disruption to work, school, and daily activities
- Ongoing anxiety due to unpredictability
Effective care helps reduce risk and improve overall quality of life.
When to See a Specialist for HAE
You should seek evaluation if you experience:
- Recurrent swelling episodes without hives
- Abdominal pain attacks with no clear cause
- Swelling that does not respond to allergy medications
- A family history of hereditary angioedema
- Facial or throat swelling episodes
Early diagnosis can be lifesaving and can prevent unnecessary treatments.
