Asthma in Children: Symptoms, Causes & Treatmen

Introduction

Children’s asthma is the same lung condition that affects adults, but their symptoms are frequently different. Childhood asthma is common and impacted by both environmental and genetic factors, which is why it is important to understand more about it.

What is Asthma in Children?

Asthma in children or childhood asthma refers to respiratory airway limitation and persistent respiratory symptoms, including wheezing, coughing, shortness of breath, and chest tightness. Although asthma can strike at any age, it usually first manifests in childhood, when your child’s immune system is still maturing. By the age of five, the majority of kids with asthma experience their first symptoms.

Symptoms of Asthma in Children

The signs and symptoms of asthma vary from child to child. 

Typical signs and symptoms of asthma include;

• Tightness or soreness in the chest, which young children may refer to as a “sore tummy.”
• Breathing difficulties.
• Breathing difficulties or dyspnoea during exercise or activities.
• wheezing, which is the sound made when exhaling (and occasionally inhaling).
• Feeling worn out or feeble.
• A chronic cough that occurs throughout the day, at night, or both.
• A cough that gets worse after contracting a virus.
• Playing with less enthusiasm; pausing during activities to collect their breath.
• Seesaw retractions or motions of the chest, where the skin pulls at the neck or in between the ribs when breathing.
• Infants who have trouble eating or who grumble while they eat.

Causes & Triggers of Childhood Asthma

Causes

Asthma’s precise cause is unknown. It frequently appears in childhood, when the immune system of your child is still maturing. It is partially inherited, according to researchers. 

However, it is thought to be caused by a confluence of environmental and genetic variables that impact a child’s immune system and lung development. Among the main factors are:

• Genetics and family history: Your child is more likely to have asthma or allergies if they run in your family.
• Allergies: Children who have allergies to mould, dust mites, pollen, or pets are more likely to develop asthma, and the symptoms of allergies can occasionally mimic those of asthma.
• Early childhood infections: Frequent colds, the flu, or other chest infections, particularly before age five, can have an impact on the development and function of the lungs.
• Environmental exposure: Inhaling mould, smoke from bushfires, air pollution, or cigarette smoke can irritate the lungs and raise the chance of developing asthma.
• Low birth weight or premature birth: Babies that are born too soon or too little may have more sensitive lungs.
• Sensitive immune system: The immune systems of certain kids respond aggressively to stimuli, which results in mucous and swelling in the airways, making breathing more difficult.

Triggers 

Factors that exacerbate asthma symptoms or create flare-ups are known as triggers. Each child may have a unique set of these, and they may evolve with time. 

Typical triggers of asthma include:

• Allergens can trigger symptoms, including dust mites, pet dander, pollen from grass, trees, and weeds, mould, and even faeces from pests like mice or cockroaches.
• Respiratory infections: Common colds, sinus infections, pneumonia, and the flu are examples of viral infections that frequently exacerbate respiratory issues.
• Irritants in the air – items like Cigarette smoke, outdoor pollution, harsh scents, and household chemicals can irritate the airways.
• Physical activity: Exercise can cause coughing, wheezing, or a tight chest (exercise-induced asthma), particularly in cold, dry, or humid weather.
• Weather variations: Some children may experience symptoms in response to cold air or abrupt weather changes.
• Emotions: Strong feelings like laughing, weeping, or even yelling can occasionally cause a flare-up.

How is Asthma Diagnosed in Children?

Children with asthma are frequently challenging to diagnose, particularly if they are younger than six years old.

The symptoms of asthma are comparable to those of other children’s illnesses. Additionally, asthma symptoms might be confused with other respiratory diseases in children who don’t experience them frequently. Furthermore, pulmonary function tests that are used to detect asthma are sometimes impossible for younger children to perform. 

However, depending on the child’s age and the clinical circumstances, several tests can be utilised to support an asthma diagnosis. 

Your child’s doctor might suggest these tests to detect asthma:

1. Physical examination: Your physician will listen to your child’s heart and lungs and check for allergy symptoms in their eyes or nose.
2. Chest X-ray: To ascertain whether the symptoms are caused by anything other than asthma, your child’s physician may decide to do a chest X-ray. Occasionally, a chest X-ray may also reveal airway abnormalities brought on by severe asthma.
3. Blood and allergy testing: Your child’s paediatrician may do skin or blood tests to look for inflammatory markers if they suspect allergies. In order to ascertain whether allergy triggers are the source of asthma symptoms, they could also decide to conduct allergy testing. 
4. Spirometry: The doctor will do a basic lung test known as spirometry if the child is five years old or older. This test measures the amount of air in the child’s lungs and how quickly they can exhale it using a device known as a spirometer.

Treatment Options for Childhood Asthma

Asthma has no known cure. Rather, asthma treatments aim to prevent persistent airway inflammation and lessen or completely eradicate the symptoms of the illness. 

Your child’s doctor will create an asthma action plan, which is a care plan based on your child’s history and the severity of their asthma. 

Important considerations for treating childhood asthma:

• Steer clear of triggers: Reduce or eliminate allergens that aggravate asthma, such as mould, dust mites, pollen, pet dander, tobacco smoke, strong odours, and air pollution.
• Use of quick-relief medications: Short-acting beta2-agonists, such as albuterol, are fast-acting medications that are used before exercise or during asthma attacks. These quickly open the airways.
• Long-term control medications: To reduce airway swelling and avoid asthma episodes, some kids require daily medications such as leukotriene modifiers or inhaled steroids.
• Allergy management: Antihistamines, allergy sprays, and allergy injections can help lessen symptoms if allergens cause asthma.
• Proper inhaler or device: Infants frequently use nebulisers, but young children may require a spacer and mask with their inhaler.
• Routine examinations: Since asthma can evolve over time, your child’s medication may need to be modified (step-up or step-down) to manage symptoms.
• If necessary, specialised care: In more severe or complex situations, an allergy physician or lung specialist (pulmonologist) can be helpful.

Living with Asthma – Lifestyle & Home Care Tips

Complications if Untreated

Childhood asthma can cause a number of severe problems and long-term implications if treatment is not received. These consist of:

Severe asthma episodes that necessitate hospitalisation or ER visits.

• Permanent lung damage: Untreated asthma can result in long-term airway damage and irreversible lung function loss.
• Missed school and other activities: Symptoms can cause kids to miss school, sports, and other events, which can have an impact on their social and intellectual growth.
• Growth or puberty delays: In certain situations, a child’s growth or puberty may be delayed as a result of poorly treated asthma.

When to Seek Immediate Medical Help

Your child should get medical attention right away if they:

• Have a severe, ongoing cough or a continuous whistling sound when breathing.
• Displays symptoms like chest retractions that indicate extreme distress.
• The colour of their cheeks, lips, or nails has changed to a pale or blue tint. (cyanosis)
• Has trouble walking or talking, finding it difficult to move or speak in complete phrases.

Conclusion

Although there is no known treatment for childhood asthma, most kids can have active, healthy lives free from the limitations of their illness with the right support and care. To avoid problems and preserve lung health, early detection and treatment are crucial. 

Complications can be avoided by being aware of triggers, according to a written asthma action plan, and taking medications as prescribed. Parents may help their children maintain good lung health, avoid emergencies, and lead normal, healthy lives by being aware of their symptoms, responding quickly during flare-ups, and collaborating closely with medical specialists.
