Pediatric Asthma in India

Pediatric asthma is a chronic inflammatory condition of the airways characterized by recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. It is one of the most common chronic diseases in childhood, affecting approximately 7.9% of children in India. A systematic review and meta-analysis examining asthma prevalence among Indian children found this consistent rate across multiple studies involving over 167,000 children. In children with asthma, the airways are hyperresponsive and become inflamed and narrow when triggered by certain stimuli such as allergens, respiratory infections, exercise, or cold air. This narrowing reduces airflow to the lungs, causing the characteristic symptoms. The prevalence is higher in urban areas compared to rural settings and more common among boys than girls. While some children may outgrow asthma as they get older, many will continue to have the condition into adulthood. With proper management including medication, trigger avoidance, and education according to Indian Academy of Pediatrics guidelines, most children with asthma can lead normal, active lives with minimal symptoms and few limitations.

Causes

Genetic predisposition - Family history of asthma or allergies increases risk, with studies in Indian families showing hereditary patterns
Allergies - Children with allergies to airborne substances like pollen, dust mites, pet dander, or mold have higher asthma risk, particularly common in Indian urban environments
Respiratory infections - Viral infections like respiratory syncytial virus (RSV) in early childhood may increase asthma risk, a common concern in densely populated Indian cities
Environmental factors - Exposure to air pollution, which is significant in many Indian urban centers, tobacco smoke, or other irritants can trigger asthma development
Indoor air pollution - Use of biomass fuels for cooking in rural Indian households is strongly associated with childhood asthma development
Early life factors - Premature birth, low birth weight, or exposure to certain medications during pregnancy
Urbanization - Children from urban areas in India show significantly higher asthma rates compared to rural settings
Gender - Studies in India confirm that before puberty, asthma is more common in boys; after puberty, it becomes more common in girls
Socioeconomic factors - In India, higher socioeconomic status is associated with increased asthma risk, possibly due to Western lifestyle influences
Climate and seasonal variations - Monsoon seasons and humidity changes in India can trigger asthma symptoms in susceptible children

In young children, irritability, difficulty feeding, or slower weight gain may be signs

Diagnosis

Medical History and Physical Examination

Following Indian Academy of Pediatrics (IAP) guidelines, the diagnostic process begins with a detailed history of symptoms, their pattern, triggers, and family history of asthma or allergies. Physical examination focuses on the respiratory system but also looks for signs of allergic conditions like eczema or allergic rhinitis, which often coexist with asthma. The doctor listens to the child's breathing with a stethoscope to detect wheezing, reduced air entry, or other abnormal sounds. IAP emphasizes checking for comorbidities like allergic rhinosinusitis (present in 75-80% of cases), obesity, GERD, and adenoidal hypertrophy.

Lung Function Tests

For children typically age 5 and older who can follow instructions, spirometry measures how much air the child can breathe in and out and how quickly. This test may be performed before and after administering a bronchodilator medication to see if lung function improves, which supports an asthma diagnosis. The IAP guidelines specify that in bronchial asthma, FEV1/FVC will be less than 80%, and a positive bronchodilator reversibility is defined as an increase in FEV1 of greater than 12% post-bronchodilator. Peak flow monitoring uses a simple handheld device to measure how fast a child can blow air out, which can help track asthma control over time, though IAP notes it has low sensitivity for initial diagnosis.

Allergy Testing

Since allergies often trigger asthma symptoms, particularly in Indian urban environments, skin prick tests or blood tests may be performed to identify specific allergens the child reacts to. Skin tests involve placing a small amount of allergen on the skin and observing for a reaction. Blood tests measure levels of specific IgE antibodies to allergens. Results help guide environmental control measures, especially for common Indian allergens like house dust mites, molds that proliferate during monsoon seasons, and pollen from local flora.

Trial of Asthma Medications

A positive response to asthma medications can support the diagnosis. Following IAP recommendations, the doctor may prescribe a short course of a bronchodilator, inhaled corticosteroid, or other asthma medication and assess whether the child's symptoms improve. This approach is particularly useful for younger children who cannot perform lung function tests and is a common diagnostic method in resource-limited settings across India.

Chest X-ray

While not needed for most cases of childhood asthma, a chest X-ray may be ordered to rule out other conditions that can cause similar symptoms, such as tuberculosis (which remains prevalent in India), pneumonia, foreign body aspiration, or structural abnormalities of the airways. It may also be performed during severe asthma exacerbations to check for complications like pneumonia or pneumothorax (collapsed lung).

Additional Tests for Complicated Cases

For difficult-to-diagnose cases, additional tests may be considered. Exhaled nitric oxide measurement detects airway inflammation. Bronchoprovocation testing deliberately exposes the child to triggers under controlled conditions to see if airways narrow. Chest CT scan provides detailed images of the lungs and airways. In tertiary care centers across India like AIIMS (All India Institute of Medical Sciences) and major hospitals in metropolitan cities, these advanced tests are performed by pediatric pulmonology specialists.

Treatment Options

Medication Management Following Indian Guidelines

Medications are the cornerstone of asthma treatment, following Indian Academy of Pediatrics (IAP) and Global Initiative for Asthma (GINA) guidelines adapted for Indian healthcare settings. Quick-relief medications (bronchodilators) like salbutamol (albuterol) relax airway muscles to provide immediate relief during symptoms or attacks and are widely available across India. Long-term control medications, taken daily, reduce inflammation and prevent symptoms. These include inhaled corticosteroids (the most effective controller medications), leukotriene modifiers, long-acting bronchodilators (for older children, always combined with corticosteroids), and biologic therapies for severe asthma available at tertiary care centers. IAP recommends a step-wise approach to medication management, with the goal of using the lowest effective doses. Age-specific therapy is proposed in steps according to clinical severity and the level of disease control.

Asthma Action Plan

Every child with asthma should have a written asthma action plan developed with their healthcare provider, a practice strongly promoted by the Indian Academy of Pediatrics. This personalized document outlines daily management, how to recognize and handle worsening symptoms, and when to seek emergency care. It typically uses a color-coded system (green, yellow, red) corresponding to different levels of symptom control. The plan includes which medications to take, when to take them, and how to adjust treatment during illnesses or symptom flares. In the Indian context, these plans are often modified to accommodate literacy levels and may include pictorial representations. Copies should be provided to schools, daycare providers, and other caregivers.

Trigger Identification and Avoidance

Identifying and minimizing exposure to asthma triggers is crucial for management in India's diverse environmental conditions. Environmental modifications may include using allergen-proof bedding covers, regular wet dusting rather than dry sweeping, controlling humidity to prevent mold (especially during monsoon seasons), eliminating exposure to tobacco smoke, addressing indoor air pollution from cooking fuels (particularly in rural areas), and using air purifiers in urban areas with high pollution levels. For children with exercise-induced symptoms, pre-treatment with medication before physical activity may be recommended. For those with allergic asthma, allergen immunotherapy may be considered to reduce sensitivity to specific allergens common in Indian environments.

Integrated Modern and Traditional Treatment Approaches

In India, many families seek a combination of conventional and traditional medicine approaches. While conventional treatments form the foundation of asthma management, Ayurvedic treatments are sometimes integrated under proper medical supervision. These might include specific dietary recommendations, breathing exercises (pranayama), and herbal remedies with potential anti-inflammatory properties. The Ayurvedic approach to asthma (known as Tamaka Shwasa) emphasizes lifestyle modifications, dietary adjustments, and specific herbs like Adhota (Malabar nut tree), Tulsi (holy basil), and turmeric. It's important that these complementary approaches are coordinated with conventional medical care and discussed with your child's healthcare provider.

Education and Skills Training

Comprehensive education for both children (age-appropriate) and caregivers is essential for successful asthma management in the Indian context. This includes understanding the nature of asthma as a chronic condition, proper use of inhalers and spacers, recognition of early warning signs of exacerbations, and the importance of adherence to treatment plans even when symptoms are absent. In India, where misconceptions about inhaler use (such as fear of dependence) are common, special emphasis is placed on education about the safety and importance of prescribed medications. Regular demonstrations of inhaler technique should be performed, as technique often deteriorates over time.

Regular Monitoring and Follow-up

Ongoing assessment of asthma control is necessary to adjust treatment as needed. Following IAP guidelines, this includes regular follow-up visits with healthcare providers, typically every 3-6 months when stable and more frequently when initiating treatment or during periods of poor control. During these visits, symptoms, medication use, emergency visits, school absences, activity limitations, and if possible, lung function are evaluated. In the Indian context, where access to specialized care may vary, there is an emphasis on training primary care physicians to manage routine asthma care, with referrals to specialists for complex cases.

Management of Comorbid Conditions

The IAP emphasizes several comorbidities associated with bronchial asthma that require management. These include allergic rhinosinusitis (associated in 75–80% of bronchial asthma cases), obesity (noting that reduction of even 5–10% of weight helps in better asthma control), GERD, adenoidal hypertrophy, and obstructive sleep apnea syndrome. In the Indian population, allergic rhinitis is particularly common and should be treated with appropriate nasal corticosteroids and antihistamines to improve asthma control. Given the rising prevalence of childhood obesity in urban India, weight management programs may benefit children whose asthma is complicated by excess weight.

Home Remedies

Creating an Asthma-Friendly Home Environment in Indian Households

Adapt your home to reduce common asthma triggers in Indian environments. In urban areas with high pollution, keep windows closed during peak traffic hours and consider air purifiers if affordable. Use door and window screens to prevent insects that can trigger allergies. In homes with indoor cooking, ensure proper ventilation, especially if using gas stoves. During monsoon season, address dampness promptly to prevent mold growth. Use allergen-proof covers on mattresses and pillows, wash bedding weekly in hot water, and minimize dust-collecting items. Remove shoes at the entrance to reduce outdoor pollutants. Ban smoking inside the home, avoid incense and strong fragrances that can trigger symptoms, and clean regularly using damp cloths rather than dry dusting to reduce airborne particles.

Developing Good Inhaler Technique

Proper inhaler technique is crucial for medication effectiveness in asthma management. Many studies in India have shown that incorrect inhaler technique is a major barrier to successful treatment. Always use a spacer device with metered-dose inhalers for children of all ages. Practice the correct sequence: shake inhaler, attach to spacer, exhale completely, place mouthpiece in mouth with tight seal (or mask for younger children), press inhaler once, take slow deep breath and hold for 10 seconds if possible, then wait 30-60 seconds before repeating if additional puffs are needed. Clean spacers weekly according to manufacturer instructions. Regularly review technique with healthcare providers and ask them to demonstrate if you're unsure.

Maintaining Physical Activity with Traditional Practices

Regular physical activity strengthens respiratory muscles and improves overall health. Work with your child's doctor to develop a pre-exercise medication routine if needed, typically using a quick-relief inhaler 15-20 minutes before activity. Traditional Indian practices like yoga and pranayama (breathing exercises) can be particularly beneficial for children with asthma. Specific breathing techniques taught by qualified instructors can help improve lung capacity and breath control. Choose activities the child enjoys and can succeed at to build confidence. Swimming is often well-tolerated as the warm, humid air can be less triggering. Be aware of seasonal variations that might exacerbate symptoms, such as dust storms, high pollen seasons, or extreme air pollution days common in many Indian cities.

Dietary Considerations and Ayurvedic Approaches

While maintaining conventional medical treatment, some dietary approaches from Ayurvedic tradition may complement asthma management. Include warming foods and spices with potential anti-inflammatory properties like turmeric (haldi) with black pepper, ginger (adrak), and honey in the diet. Ayurvedic practitioners often recommend warm foods and drinks rather than cold items. Certain fruits like pomegranate and foods rich in antioxidants may help reduce inflammation. Some families find that a teaspoon of honey mixed with warm water or ginger tea helps soothe the throat during minor symptoms. Always consult with your child's doctor before making significant dietary changes or trying herbal remedies, and never use these as a replacement for prescribed medications.

Supporting Emotional Well-being

Help your child develop a positive attitude toward asthma management rather than feeling limited by the condition. In the Indian context, where chronic conditions may sometimes be stigmatized, it's important to educate family members and school staff about asthma to ensure proper support. Encourage age-appropriate understanding and gradual responsibility for self-management. Consider connecting with other families through asthma support groups that are becoming more common in urban centers across India. Watch for signs of anxiety or depression, which can both trigger and result from asthma symptoms. Teach simple relaxation techniques like deep breathing or progressive muscle relaxation, which can help during episodes of breathlessness and reduce anxiety.

Preventing and Managing Respiratory Infections

Since respiratory infections are common asthma triggers in children, especially in India where respiratory infections are prevalent, emphasize good hand hygiene and teach proper handwashing technique. Ensure your child receives recommended vaccinations, including annual influenza vaccine. In crowded urban settings, avoid close contact with people who have colds or other infections when possible. Develop a clear plan with your doctor for adjusting asthma medications during illnesses. Start interventions at the first sign of a cold rather than waiting for asthma symptoms to worsen. Maintain adequate hydration during illnesses to help thin mucus secretions, particularly important during hot Indian summers.

Preventive Care

Adhere to prescribed controller medications even when the child feels well, as these prevent inflammation and reduce the risk of exacerbations; in India, where medication adherence can be a challenge due to misconceptions, emphasize the importance of regular controller use
Keep rescue medication (e.g., salbutamol/albuterol) available at all times, including at school, during travel, and for extracurricular activities; ensure medications haven't expired, particularly important in hot and humid Indian climates
Ensure annual influenza vaccination and stay current with all recommended immunizations as per the Indian Academy of Pediatrics schedule to prevent respiratory infections that can trigger asthma
Schedule regular follow-up appointments with healthcare providers to monitor asthma control and adjust treatment as needed; if living in a remote area, consider telemedicine options now available across many parts of India
Maintain an updated written asthma action plan (in the appropriate local language) and review it regularly with all caregivers, teachers, and school nurses; pictorial action plans may be useful for families with limited literacy
Consider allergen immunotherapy for children with significant allergic triggers common in India (house dust mites, local pollens, molds) that cannot be adequately avoided, available at major allergy centers in metropolitan areas
Monitor and record symptoms, medication use, and peak flow measurements (if appropriate) to identify patterns and early warning signs; smartphone apps for asthma tracking are becoming increasingly available in India
Avoid exposure to tobacco smoke, biomass fuel smoke from cooking, and other indoor air pollutants common in Indian households; encourage family members who smoke to quit or smoke only outdoors
During festivals like Diwali or Holi that may involve air pollution or color powders, take extra precautions and possibly increase preventive medications as advised by your doctor
Teach children age-appropriate self-management skills, gradually increasing responsibility as they mature; this is particularly important in India where extended family members may have varying understanding of asthma management
Ensure proper nutrition following a balanced Indian diet, adequate sleep, and regular physical activity to support overall health and immune function
Be prepared for seasonal changes in asthma triggers specific to Indian climate zones (monsoon, winter smog in northern cities, dust storms, harvest seasons) and adjust environmental controls and medications proactively
Work with school personnel to ensure appropriate asthma management during school hours, helping to overcome the stigma sometimes associated with chronic conditions in Indian school settings

Surgical Options

Bronchial Thermoplasty

This minimally invasive procedure is rarely used in children and is reserved for older adolescents (typically 18 years and older) with severe, persistent asthma that remains poorly controlled despite maximal medical therapy. In India, this advanced procedure is available only at select tertiary care centers in major metropolitan cities like Delhi, Mumbai, Chennai, and Bangalore. It involves delivering controlled thermal energy to the airways during bronchoscopy, which reduces the amount of smooth muscle in the airway walls. This decreases the ability of the airways to constrict during an asthma attack. The procedure is performed in three separate sessions, each treating different sections of the lungs. While not a cure, it may reduce severe exacerbations and emergency visits in carefully selected patients with severe refractory asthma.

Note on Surgical Options for Pediatric Asthma in India

Unlike some other medical conditions, asthma is primarily managed with medications, environmental control measures, and education rather than surgical interventions. True surgical options specifically for asthma treatment are extremely limited, with bronchial thermoplasty being the only procedure directly targeting asthma pathophysiology, and even this is rarely used in pediatric populations in India. The Indian Academy of Pediatrics emphasizes medical management as the mainstay of treatment. However, surgery may sometimes be indicated for conditions that can worsen asthma control, with access to these procedures varying widely across different regions of India.

Adenotonsillectomy

While not a direct treatment for asthma itself, removal of enlarged adenoids and tonsils may be beneficial for some children who have both asthma and obstructive sleep apnea or recurrent upper airway infections that trigger asthma exacerbations. This is a relatively common procedure in India and is available at most district and tertiary hospitals. By improving upper airway patency and reducing infections, this procedure may indirectly improve asthma control in selected cases. In India, where upper respiratory infections are common triggers for asthma exacerbations, this procedure may be particularly beneficial for selected patients. The decision involves weighing potential benefits against surgical risks, and is made in consultation with otolaryngology specialists.

Endoscopic Sinus Surgery

For children with severe chronic sinusitis that triggers or exacerbates asthma and has not responded to medical management, endoscopic sinus surgery may be considered. In India, chronic sinusitis is relatively common due to environmental factors and high prevalence of allergic rhinitis. This procedure improves drainage from the sinuses and can reduce the frequency of sinus infections. Since upper and lower airways are closely linked (the "unified airway" concept), better control of chronic sinusitis may lead to improved asthma outcomes in some patients. The procedure is available at most ENT departments in major Indian hospitals, though pediatric cases are typically referred to specialized centers. This approach is typically considered only after extended trials of medical therapy including nasal corticosteroids and saline irrigation.

Anti-reflux Procedures

In rare cases where severe gastroesophageal reflux disease (GERD) contributes significantly to poorly controlled asthma despite maximal medical therapy, anti-reflux surgery such as Nissen fundoplication might be considered. GERD is increasingly recognized as a comorbidity in Indian children with asthma, though dietary factors and management approaches may differ from Western populations. However, evidence for improvement in asthma outcomes following such procedures is limited, and they are generally reserved for children with severe reflux symptoms or complications beyond asthma exacerbations. In India, these procedures are typically performed at pediatric surgical centers in major cities. Careful evaluation by a multidisciplinary team is essential before pursuing this approach.
