Asthma is one of the most common long-term health conditions affecting children. In many cases, symptoms can be managed successfully with the right medication, regular reviews, and avoiding known triggers. When your child’s asthma is well controlled, they can usually take part in school, sports, and everyday activities with minimal disruption.
However, some children continue to experience frequent symptoms despite following their treatment plan carefully. If your child regularly has wheezing, coughing, breathlessness, or asthma attacks, it may be a sign that their condition requires further investigation. In these situations, specialist assessment can help identify factors that may be preventing good asthma control.
Although severe childhood asthma is relatively uncommon, it can have a significant impact on your child’s health and quality of life. Ongoing symptoms may affect sleep, school attendance, physical activity, and overall wellbeing. Understanding when specialist care may be needed can help you access the most appropriate support and treatment for your child.
Understanding Childhood Asthma
Asthma is a condition that causes inflammation and narrowing of your child’s airways, making it more difficult for air to move in and out of the lungs. This can lead to symptoms such as wheezing, coughing, chest tightness, and shortness of breath. These symptoms may occur occasionally or become more frequent depending on how well the asthma is controlled.
Every child experiences asthma differently. While some children only develop symptoms from time to time, others may need ongoing treatment to keep their condition under control. You may also notice that your child’s symptoms change over time or worsen when exposed to certain triggers, such as infections, exercise, pollen, or cold weather.
The aim of asthma management is to reduce symptoms and prevent asthma attacks. With the right treatment plan, regular monitoring, and good trigger management, many children can lead active and healthy lives. Helping your child maintain good asthma control can also reduce the risk of future complications and hospital visits.
What Is Severe Asthma?
Severe asthma usually refers to asthma that remains poorly controlled despite appropriate high-level treatment, confirmed diagnosis, good inhaler technique, and regular use of prescribed medication. Even when you follow your child’s treatment plan correctly, they may continue to experience frequent symptoms, asthma attacks, or limitations in their daily activities. This can make asthma more challenging to manage and may affect your child’s quality of life.
Severe asthma is different from mild or moderate asthma, which is often controlled with standard treatments. Children with severe asthma typically require more detailed investigation to understand why their symptoms persist. In many cases, specialist assessment is needed to identify contributing factors and develop a more tailored treatment approach.
Accurate diagnosis is an important part of the process. Some conditions can cause symptoms that closely resemble asthma, making it essential to confirm the underlying cause of your child’s breathing difficulties. A thorough evaluation can help ensure your child receives the most appropriate care and support.
Evidence Note:
International ERS/ATS guidance defines severe asthma as asthma that requires high-dose inhaled corticosteroids plus another controller medication, and/or systemic corticosteroids, to prevent it from becoming uncontrolled, or asthma that remains uncontrolled despite this treatment. For parents, this means a child should not be labelled as having severe asthma simply because they cough or wheeze often. First, clinicians need to check whether the diagnosis is correct, whether inhalers are being used properly, whether medication is being taken regularly, and whether triggers or other conditions are making symptoms worse.
How Common Is Severe Asthma in Children?
Most children with asthma do not have severe disease. With appropriate treatment and regular monitoring, many are able to achieve good symptom control and lead active lives. This means your child may be able to manage their condition effectively with standard asthma therapies.
Only a small percentage of children with asthma have severe asthma. However, these cases often account for a significant number of asthma-related healthcare visits, emergency attendances, and hospital admissions. If your child’s symptoms remain difficult to control, further assessment may be needed.
Early recognition of severe asthma is important for achieving the best possible outcomes. Identifying ongoing symptoms and treatment challenges can help ensure your child receives appropriate care as soon as possible. This may reduce the risk of complications and improve your child’s quality of life.
Common Symptoms of Severe Asthma

Children with severe asthma may experience symptoms more frequently than those with milder forms of the condition. Symptoms can occur during the day, at night, or when your child is physically active. In some cases, these symptoms may persist despite regular treatment.
Common symptoms include persistent coughing, wheezing, breathlessness, and chest tightness. You may notice that your child becomes short of breath more easily or struggles to participate in normal activities. Some children may also experience repeated asthma attacks that require urgent medical attention.
These symptoms can have a significant impact on your child’s daily life. Severe asthma may affect sleep, school attendance, physical activity, and overall wellbeing. Early assessment can help you understand the severity of your child’s condition and identify appropriate treatment options.
| Warning sign | What it may suggest | Why specialist review may help |
| Frequent daytime symptoms | Asthma may not be well controlled | Treatment plan may need adjustment |
| Night-time coughing or wheezing | Ongoing airway inflammation | Control and triggers should be reviewed |
| Repeated asthma attacks | Higher risk of emergency care | Specialist assessment can reduce future risk |
| Frequent reliever inhaler use | Preventer treatment may not be enough or not reaching the lungs | Inhaler technique and medication plan should be checked |
| Missed school or avoided sport | Asthma is affecting quality of life | A personalised care plan may help |
| Hospital or A&E attendance | Higher-risk asthma pattern | Specialist referral is often appropriate |
Frequent Asthma Attacks
Frequent asthma attacks can be an important warning sign that your child’s asthma is not well controlled. These episodes may occur despite regular treatment and can sometimes require urgent medical attention. If your child experiences repeated attacks, further assessment may be necessary.
Recurrent asthma attacks can increase the risk of complications and may affect your child’s overall health and wellbeing. You may also notice increased symptoms between attacks, such as coughing, wheezing, or breathlessness. These signs can indicate that current treatment is not providing adequate control.
A specialist assessment is often recommended when asthma attacks occur repeatedly. This allows clinicians to identify potential triggers, review your child’s treatment plan, and explore additional management options. Early intervention can help reduce future attacks and improve your child’s quality of life.
Night-Time Symptoms
Children with poorly controlled asthma often experience symptoms during the night. You may notice that your child wakes frequently due to coughing, wheezing, or breathlessness. These symptoms can occur even when daytime symptoms appear relatively mild.
Poor sleep can have a significant impact on your child’s daily life. If your child is regularly waking during the night, it may affect concentration, mood, behaviour, and performance at school. Night-time symptoms can also be a sign of ongoing airway inflammation.
It is important not to ignore persistent night-time asthma symptoms. If your child’s sleep is being disrupted regularly, their asthma may not be adequately controlled. A medical review can help you identify the cause and determine whether adjustments to treatment are needed.
Impact on School and Activities
Severe asthma can affect many aspects of your child’s daily life. Frequent symptoms, asthma attacks, or medical appointments may cause your child to miss school more often than their peers. This can sometimes make it more difficult for them to keep up with lessons and school activities.
Breathing difficulties may also limit your child’s participation in sports and other physical activities. You may notice that your child avoids exercise because it triggers symptoms or causes discomfort. Over time, this can affect both physical fitness and social confidence.
Improving asthma control can help your child take part in more of the activities they enjoy. With appropriate treatment and support, your child may feel more confident at school, during exercise, and in social situations. Better symptom management can have a positive impact on overall wellbeing and quality of life.
Identifying Asthma Triggers
Asthma symptoms in children are often triggered by environmental or lifestyle factors. Common triggers include viral infections, pollen, dust mites, pet dander, smoke, and air pollution. Recognising what affects your child can help reduce exposure and minimise symptom flare-ups.
- Seasonal and Allergen Patterns: Symptoms may worsen during certain seasons or after exposure to allergens such as pollen or pet dander.
- Respiratory Infections: Viral infections can trigger asthma attacks and increase symptom severity.
- Environmental Factors: Smoke, dust, and air pollution can contribute to worsening asthma symptoms.
- Comprehensive Management Needed: Avoiding triggers alone is rarely enough; regular medical treatment and monitoring are important for controlling severe asthma.
Overall, identifying triggers is a key part of managing childhood asthma. By recognising patterns and reducing exposure where possible, you can help minimise symptoms, but ongoing medical care remains essential for effective control.
The Importance of Correct Diagnosis

Not every child with ongoing respiratory symptoms has severe asthma. Several other conditions can cause similar symptoms, including persistent coughing, wheezing, or breathlessness. This is why it is important for your child to receive a thorough medical assessment.
A specialist evaluation can help confirm whether severe asthma is the underlying cause of your child’s symptoms. It can also identify other factors that may be contributing to breathing difficulties or poor symptom control. This helps ensure that your child receives the most appropriate treatment.
Accurate diagnosis is the foundation of effective asthma management. Once the cause of your child’s symptoms has been identified, a tailored treatment plan can be developed. This gives your child the best opportunity to achieve improved symptom control and a better quality of life.
UK Guidance Note:
In the UK, the BTS/NICE/SIGN asthma guideline recommends that asthma should not be confirmed without both a suggestive clinical history and supporting objective testing where possible. For children aged 5 to 16, this may include tests such as FeNO, spirometry with bronchodilator reversibility, peak flow monitoring, allergy-related testing, or referral for specialist assessment if the diagnosis remains uncertain. For children under 5, diagnosis can be more difficult because objective testing may not always be possible, so regular review and specialist referral may be needed if symptoms do not respond to treatment.
Assessing Treatment Adherence
Before diagnosing severe asthma, clinicians will often review how your child’s medications are being used. Incorrect inhaler technique or missed doses can reduce the effectiveness of treatment and make symptoms more difficult to control. In some cases, these factors may contribute significantly to ongoing asthma problems.
Many children experience improved asthma control once medication use is optimised. Ensuring that your child uses their inhaler correctly and follows their prescribed treatment plan can make a noticeable difference. Regular reviews can help identify and address any issues early.
This assessment is an important part of a specialist asthma evaluation. By understanding how treatment is being used, clinicians can determine whether symptoms are due to severe asthma or other manageable factors. This helps ensure that your child receives the most appropriate care and support.
Inhaler Technique and Asthma Control
Even the most effective asthma medications may not work as intended if an inhaler is used incorrectly. For this reason, it is important that both you and your child receive clear guidance on the correct inhaler technique. Proper use helps ensure that the medication reaches the airways where it is needed most.
Regular reviews of inhaler technique can help identify and correct any problems. You may be surprised to find that small adjustments can make a significant difference to your child’s symptom control. These checks are an important part of ongoing asthma management.
Education remains a key component of effective asthma care. By understanding how medications work and how to use inhalers correctly, you can help your child get the greatest benefit from treatment. This can contribute to better asthma control and improved quality of life.
Clinical Tip:
Before increasing asthma medication, it is important to check whether the inhaler is being used correctly and consistently. NICE/BTS/SIGN guidance recommends considering reasons for uncontrolled asthma before changing treatment, including alternative diagnoses, other medical conditions, poor adherence, incorrect inhaler technique, smoke exposure, vaping exposure, seasonal triggers, air pollution, indoor mould and psychosocial factors.
Investigating Underlying Factors
Several factors can contribute to poor asthma control, even when your child is receiving treatment. These may include allergies, exposure to tobacco smoke, obesity, or untreated nasal and sinus conditions. Identifying these issues can help explain why symptoms remain difficult to manage.
As part of a comprehensive assessment, specialists will often investigate factors that may be affecting your child’s asthma. This allows them to build a clearer picture of your child’s overall health and identify any additional concerns. You may find that addressing these issues helps improve symptom control.
Asthma management is often most effective when multiple aspects of care are considered. Alongside medication, your child may benefit from strategies that target contributing factors and reduce symptom triggers. This more holistic approach can help improve both asthma control and quality of life.
Advanced Diagnostic Testing
Children with suspected severe asthma may require additional diagnostic tests to better understand their condition. These investigations can provide more detailed information about lung function and levels of airway inflammation. This helps your specialist assess how well your child’s lungs are working.
The results of these tests can guide treatment decisions and help confirm whether severe asthma is present. In some cases, testing may also identify alternative diagnoses that explain your child’s symptoms. This ensures that your child receives the most appropriate and effective care.
Advanced diagnostic testing can also support long-term monitoring of your child’s asthma. Specialist clinics often have access to these tools, allowing for more precise and tailored assessment. This can help you and your clinician track progress and adjust treatment when needed.
Medication Options for Severe Asthma

Children with severe asthma may require more intensive treatment compared to those with milder forms of the condition. This can include higher doses of inhaled medications or the addition of other therapies to help control symptoms. The goal is to reduce inflammation and improve breathing as effectively as possible.
Treatment plans are always tailored to your child’s individual needs and symptom pattern. Your clinician will aim to find the lowest effective dose that provides good asthma control while minimising side effects. This personalised approach helps ensure that your child receives the most appropriate treatment.
Regular review is an essential part of ongoing asthma management. You may notice that treatment is adjusted over time based on how well your child is responding. This helps maintain optimal control and ensures the treatment continues to meet your child’s needs.
Biologic Therapies
Biologic therapies are specialist medicines that may be used for selected children with severe asthma when standard treatments are not providing enough control. They are usually considered only after the diagnosis has been reviewed, inhaler technique and adherence have been checked, and triggers or other contributing factors have been addressed.
These medicines target specific inflammatory pathways involved in some types of asthma, such as allergic or eosinophilic asthma. They are not suitable for every child, so blood tests, allergy testing, symptom history and asthma attack frequency may all be considered before treatment is recommended.
In the UK, biologic therapies for severe asthma are specialist treatments with specific eligibility criteria. They may be considered for selected children or adolescents with confirmed severe asthma, depending on age, asthma type, biomarkers such as IgE, eosinophils or FeNO, exacerbation history, and current NICE/NHS guidance. These treatments are not suitable for every child and should only be considered after diagnosis, inhaler technique, adherence, triggers and other contributing conditions have been carefully reviewed.
Monitoring and Follow-Up
Children with severe asthma require regular monitoring to assess how well their symptoms are controlled and how they are responding to treatment. During follow-up appointments, your clinician may review your child’s progress and make adjustments to the management plan if needed. This helps ensure that your child continues to receive the most effective care.
Monitoring may include lung function testing, symptom tracking, and a detailed review of how your child has been feeling since the last visit. You may also be asked about night-time symptoms, activity levels, and any recent asthma attacks. These regular checks help build a clear picture of your child’s condition over time.
Consistent follow-up is important for achieving better long-term outcomes. By attending regular appointments, you can help ensure that any changes in your child’s asthma are identified early. Ongoing care plays a key role in maintaining stable symptoms and improving your child’s overall quality of life.
Creating an Asthma Action Plan
An asthma action plan gives you clear, step-by-step instructions on how to manage your child’s symptoms. It helps you recognise early warning signs and know exactly what to do if your child’s asthma begins to worsen. This can make day-to-day management feel more structured and less stressful for you.
If your child’s symptoms worsen or they have an asthma attack, the action plan guides you on the next steps to take. This may include adjusting medication or seeking medical help when needed. Having this plan in place means you can respond quickly and confidently if your child’s condition changes.
Asthma action plans are especially important for children with severe asthma. They can help you feel more prepared and in control during difficult situations. It is important that you fully understand your child’s plan and follow it closely to support better asthma management.
When Should a Child Be Referred to a Specialist?
Referral to a specialist is often recommended when your child’s asthma remains poorly controlled despite appropriate treatment. If your child continues to experience frequent attacks, repeated hospital admissions, or ongoing symptoms, it may be a sign that further assessment is needed. This helps ensure that nothing important is being missed in your child’s care.
A specialist can carry out a more detailed investigation to identify any underlying causes of poor control. They may also review your child’s current treatment plan and explore additional or alternative options. This can help ensure that your child receives the most suitable and effective care for their condition.
Early specialist referral may support better long-term asthma control for your child. You may find that expert input helps achieve better symptom control and reduces the risk of future complications. Seeking specialist advice can be an important step towards improving your child’s overall asthma management.
Supporting Children and Families

Living with severe asthma can be challenging for both you and your child. Worries about symptoms, school attendance, and long-term health can sometimes feel overwhelming for your family. These concerns are completely understandable when managing a long-term condition.
Education and clear communication with healthcare professionals can make a significant difference. When you understand your child’s condition better, you may feel more confident in managing symptoms day to day. Regular support from your care team can also help you feel more in control.
Emotional support is an important part of asthma care. You may find it helpful to talk openly with your child about their symptoms and feelings. With the right guidance and reassurance, you can help your child feel more secure and supported in managing their condition.
Accessing Specialist Asthma Care
If your child continues to experience persistent symptoms despite regular treatment, specialist assessment may help identify further management options. This can provide a clearer understanding of why symptoms are ongoing and what adjustments may be needed. You may find that a more detailed evaluation helps improve your child’s asthma control.
Early intervention is important in reducing the risk of complications associated with poorly controlled asthma. By seeking specialist care sooner, you can help ensure your child receives the most appropriate treatment at the right time. This may lead to fewer symptoms and better day-to-day stability.
Accessing specialist asthma care can also improve your confidence in managing your child’s condition. You may receive additional support, education, and treatment strategies tailored specifically to your child’s needs. Overall, this approach aims to improve both health outcomes and quality of life.
When to Seek Urgent Help
Severe asthma care is important, but some symptoms need emergency attention rather than a routine appointment. Call 999 if your child is having an asthma attack and is getting worse, does not improve after using the maximum reliever dose in their asthma action plan, or does not have their reliever inhaler available. NHS advice also recommends using the reliever inhaler again after 10 minutes if symptoms are no better and the ambulance has not arrived.
You should also seek urgent help if your child is struggling to speak, breathing very hard, becoming drowsy, looking blue around the lips, or you feel seriously worried about their breathing. It is always safer to act quickly if your child’s asthma symptoms feel severe or unusual.
