Caring for a child with angioedema can be challenging and requires preparation, vigilance, and adaptability as a parent.

Angioedema causes episodes of swelling under the skin, commonly affecting areas like the face, throat, and limbs. These episodes are often unpredictable and, in severe cases, life-threatening.

Recognizing your child’s angioedema symptoms and triggers can help you better manage their condition and support their physical and emotional health.

Understanding angioedema in children

You can become better at managing angioedema in children by learning more about the type, symptoms, and triggers of your child’s disease.

Being able to identify and reduce exposure to the triggers that can lead to an attack can help lessen the frequency and severity of your child’s angioedema symptoms.

Children, especially when younger, may have trouble describing how they feel during a swelling episode, so being able to recognize their symptoms means you might have the chance to start treatment before the swelling progresses.

Types of angioedema

The different types of angioedema have different causes, including allergies, reactions to medications, and genetic factors.

In children, the most common form is acute allergic angioedema, often triggered by environmental allergens like food, insect stings, or medications. This type is estimated to account for up to 70% of angioedema cases across people of all ages.

Other forms of angioedema that are more commonly seen in children include:

Rarely, children may also have acquired angioedema, a type of angioedema typically caused by other illnesses arising later in life, or drug-induced nonallergic angioedema — a form of angioedema that develops as a side effect of certain medications, commonly angiotensin-converting enzyme (ACE) inhibitors.

ACE inhibitors are medications that are used to lower blood pressure. Because they are not frequently prescribed to children, drug-induced nonallergic angioedema caused by these medications is not typically seen in children.

Urticaria, or hives, and angioedema sometimes happen together. A reaction involving hives can help identify the type of angioedema. For example, hives are often seen with allergy-related angioedema, but are rare in HAE.

Although angioedema isn’t the same as an allergy or asthma, children with these conditions may have overlapping triggers, such as certain foods, environmental allergens, or stress.

Recognizing and managing these shared triggers can be a way to reduce the risk of an angioedema attack.

Symptoms

Swelling is the primary clinical feature of angioedema. It can occur anywhere on the body, but most commonly in the face, hands, feet, throat, gut, or genitals. It typically develops in the deeper layers of the skin, leading to large, smooth, or raised areas.

While all types of angioedema involve swelling, the particular patterns and accompanying symptoms can vary depending on the type.

Swelling in the face, lips, or tongue can interfere with your child’s ability to talk. It’s important to watch for non-verbal signs that your child is uncomfortable, in pain, or in distress, such as:

  • fussiness, clinginess, or irritability
  • crying in a prolonged or high-pitched manner
  • guarding a part of their body, or flinching when touched
  • swelling, redness, or changes in skin temperature
  • refusing to eat or drink, or having changes in sleep

Swelling in the throat can make it hard to swallow, which may cause choking. Swelling is dangerous when it starts to block the airways. Difficulty breathing can worsen rapidly and require immediate treatment at a hospital or emergency department.

Causes and triggers

Angioedema can be caused by a variety of factors, including certain foods, medications, genetics, and environmental factors.

Some of the most common causes of angioedema include allergic reactions to foods such as nuts, shellfish, and dairy, as well as medications like aspirin, and antibiotics​. Environmental factors, such as pollen, can also trigger episodes of swelling​.

How to recognize early signs of angioedema in children

Often, the first sign of angioedema is puffiness in areas like your child’s face, lips, or hands.

Along with visible swelling, other signs may include skin that feels warm to the touch, nausea, fever, and flu-like symptoms. If swelling is triggered by an allergy, your child may also be itchy or have a rash.

As young children may have trouble noticing or explaining that they are feeling a swelling episode, be alert to subtle signs of discomfort, including changes in behavior, difficulty eating, or trouble speaking.

Other warning signs of an oncoming attack are abdominal pain, fatigue, irritability or other emotional changes.

Diagnosis and treatment options

Diagnosing angioedema in children typically involves a comprehensive review of their symptoms, a detailed account of medical and family history, and tests to confirm their condition.

A physical examination can identify signs like swelling, while allergy and blood tests can pinpoint the type of angioedema, including HAE.

Support your child during doctor visits, exams, and tests by:

  • staying calm and offering reassurance to help ease their anxiety
  • explaining each step in simple, age-appropriate terms to give them a sense of control
  • bringing a favorite toy or book to comfort them
  • asking the healthcare provider for breaks if needed
  • praising them for being brave and offering a small reward afterward

Angioedema treatment depends on the underlying cause.

For allergic reactions, treatment may involve antihistamines, steroids, or adrenaline (epinephrine) for emergency use to manage acute symptoms.

HAE treatments try to counteract the effects of the genetic mutations leading to swelling. For instance, C1 esterase inhibitors, which work to provide a protein that is missing or dysfunctional in most cases of HAE, can help to prevent or reduce the frequency of swelling episodes.

Managing angioedema at home

Staying ahead of potential issues in your child’s care is not just about managing their health — it’s about offering them stability and reassurance. This includes keeping track of warning signs, managing swelling episodes, and preparing an emergency plan.

Her are some steps you can take at home to help manage angioedema:

  • Reduce your child’s exposure to common triggers like food allergens (such as shellfish, nuts, or dairy) and environmental irritants (such as pollen or dust) by creating an allergen-free home environment and reading food labels carefully.
  • Focus on anti-inflammatory foods in your child’s diet, such as fruits, vegetables, lean proteins, and whole grains, to help reduce the risk of attacks.
  • Use a cool compress during mild swelling episodes and encourage rest to help relieve discomfort in the affected areas.
  • Follow gentle skincare routines by choosing fragrance-free, hypoallergenic products to protect your child’s skin.
  • Prepare a home kit with prescribed medications, an epinephrine injector (if recommended), emergency instructions, and key contact numbers,. Review this with family members to ensure everyone is prepared for emergencies.

Emotional support and education

Caring for a child with angioedema takes more than managing their physical symptoms.

It can involve recognizing the emotional challenges your child may face while living with a chronic health condition and offering age-appropriate information about angioedema.

It’s also important to learn strategies that help you cope with your own feelings.

Coping strategies for parents

The unpredictable nature of angioedema attacks can require constant attention on your part. This may lead to feelings of anxiety as you manage your child’s triggers and deal with their medical needs.

Countering these feelings with stress management, mental health support, and a sustainable daily routine can assist you in coping with the demands of caregiving.

Try to find ways to include personal time and breaks throughout the day to reduce the fatigue that can be a part of caregiving. Making time for activities you enjoy can replenish your energy.

If your emotions become overwhelming, talk to a friend or family member, or consider professional counseling.

Teaching your child about their condition

To better understand how to talk to your child about angioedema, start by learning more about their condition.

Your child’s healthcare provider can discuss the triggers, symptoms, and best approaches for treatment and day-to-day management of your child’s type of angioedema.

You can also explore other reliable sources for more information, like medical organizations and patient advocacy groups.

When sharing this knowledge with a young child, it can be useful to use simple, relatable terms to make the information easier for them to understand.

For example, you might tell them that:

  • their body gets really puffy in certain places because of a condition called angioedema
  • there are things you can do together to make them feel better
  • if certain things are avoided, the puffiness may stop before it starts
  • you will answer any questions they may have
  • you are always there to help them

Encourage your child to express how they feel when they notice symptoms, even if it’s difficult for them to describe what is making them uncomfortable.

As your child gets older, you can add more details about what causes their angioedema and how to manage it.

Finding support groups and resources

Reach out for support when you need it. Family, friends, healthcare professionals, and support groups can offer practical advice to help you raise a child with angioedema.

Regularly connecting with people who understand the challenges of angioedema can foster a sense of community and provide encouragement, making you feel more equipped and supported in your caregiving role.

Online and in-person support groups can serve as a parental guide, providing insights, emotional support, and practical advice from other parents managing angioedema in their children.

While many organizations primarily focus on HAE, there are some groups that can provide resources and guidance on managing different types of angioedema, including non-hereditary types.

Two resources include the American Academy of Allergy, Asthma, and Immunology and the Allergy & Asthma Network.

To connect with other parents and caregivers of children with HAE, check organizations like the U.S. Hereditary Angioedema Association, HAE Canada, HAE UK, and HAE International.

Angioedema News also offers the latest news and perspectives on HAE and other forms of the disease, as well as connections on social media, including Facebook, X, and Instagram.

Making a plan with your healthcare team

Establishing good communication with your child’s healthcare team is key to creating a comprehensive care plan.

Your child’s pediatrician and allergist can help you understand their needs and work with you to develop a plan that manages both routine care and emergency situations.

Your child’s treatment plan can include:

  • strategies for avoiding or minimizing exposure to known triggers
  • guidelines for when to contact your healthcare provider, especially if symptoms change or worsen, and when to seek emergency medical care
  • instructions for administering medications, including both long-term treatments and emergency interventions
  • a step-by-step guide on how to manage an acute angioedema episode
  • a list of emergency contacts, including family members, your child’s specialists, and nearby healthcare facilities

Keeping a symptom diary can help track your child’s angioedema episodes, including severity, duration, and potential triggers. Sharing this record with their healthcare team can provide insight into patterns that may guide adjustments to their treatment plan.
