Childhood Asthma in Pokhara: Triggers, Treatment and Daily Management

Asthma is the most common chronic respiratory disease in childhood globally. In Nepal, its prevalence is increasing — driven by urbanization, air quality changes, and increased recognition. Many children in Pokhara with recurrent wheezing go undiagnosed or undertreated, resulting in repeated emergency visits, missed school days, and activity limitations that are avoidable with correct management.

What Is the Difference Between Asthma and Reactive Airway Disease in Children?

Reactive airway disease (RAD) is a broad clinical term used when a child under 2 years has recurrent wheezing without a definitive asthma diagnosis. Asthma is the specific diagnosis given when wheeze is recurrent, responds to bronchodilator treatment, and has an identifiable pattern of triggers. After age 5, spirometry can confirm asthma by demonstrating reversible airflow obstruction.

Both asthma and reactive airway disease involve bronchospasm — narrowing of the small airways — and airway inflammation. In practice, both are managed similarly with bronchodilators and anti-inflammatory medications, and the term distinction matters more for prognosis counseling than for immediate treatment decisions.

Children with reactive airway disease in infancy often — but not always — go on to develop confirmed asthma. Risk factors for persistence include:

• A parent with asthma
• Eczema or allergic rhinitis in the child
• Wheeze triggered by non-respiratory viral infections (e.g., exercise, cold air, emotion)
• Elevated blood eosinophil count or IgE

What Triggers Asthma in Children in Nepal and Pokhara?

Common asthma triggers in Nepali children include house dust mite, mold, tobacco smoke, cooking smoke, cold air, pollen, and respiratory viral infections. Recognizing and reducing exposure to specific triggers is a central part of long-term asthma control.

Indoor triggers (highest impact):

• House dust mite — the most common asthma trigger in South Asia. Thrives in bedding, carpets, upholstered furniture, and humid environments. Pokhara’s lakeside humidity creates favorable conditions.
• Cockroach allergens — present in kitchen environments.
• Mold and dampness — common in older buildings during monsoon season.
• Tobacco smoke — passive exposure is a significant trigger and increases asthma severity.
• Cooking smoke — biomass fuel (wood, dung cake) generates particulate matter and gases that trigger bronchospasm.
• Pet dander — dogs and cats in the home.

Outdoor and environmental triggers:

• Cold air — exercise in cold morning air is a common trigger.
• Pollen — seasonal, particularly spring.
• Air pollution — vehicle exhaust, construction dust, open burning.
• Respiratory viral infections — rhinovirus (common cold virus) is the most frequent trigger of asthma exacerbations in children.

Exercise-induced bronchospasm: Wheezing or coughing during or after vigorous exercise is often the first presentation of asthma in school-age children. Pre-exercise reliever inhaler use 15 minutes before exercise prevents this.

How Is Asthma Diagnosed in Children?

Asthma diagnosis in children under 5 is clinical — based on recurrent wheeze, trigger pattern, and response to bronchodilators. In children over 5, spirometry measures FEV1 (forced expiratory volume) before and after bronchodilator. A greater than 12% improvement in FEV1 confirms reversible airflow obstruction, which is characteristic of asthma.

Diagnostic indicators used by pediatricians:

• Recurrent wheeze (3 or more episodes)
• Nocturnal or early-morning cough
• Cough or wheeze triggered by exercise, cold air, or allergen exposure
• Improvement with reliever bronchodilator (salbutamol)
• Family history of asthma or allergy
• Eczema or allergic rhinitis in the child

A chest X-ray is not required to diagnose asthma but is used to exclude other causes of wheeze (foreign body, lung malformation). Blood eosinophil count and total IgE may support the allergic component. Allergy skin prick testing can identify specific allergens where trigger control is being planned.

How Do You Recognize an Asthma Attack in a Child?

A mild asthma attack presents as wheeze with mild increased work of breathing. The child can speak in full sentences, is alert, and responds quickly to a reliever inhaler. A severe attack involves significant respiratory distress — the child cannot speak in full sentences, has visible intercostal or subcostal retractions, and oxygen saturation drops below 94%.

Signs of a severe asthma attack requiring immediate emergency care:

• Fast breathing rate with visible chest wall movement
• Using neck muscles, shoulder muscles to breathe (accessory muscle use)
• Skin pulling in at the throat (tracheal tug)
• Unable to complete a sentence without stopping to breathe
• Oxygen saturation below 92% on pulse oximeter
• Silence on auscultation (silent chest) — indicates severe obstruction
• Child appears exhausted, drowsy, or confused

Go immediately to A&B International Hospital emergency for any severe asthma attack. Do not drive and wait — call for help.

What Is the Correct Inhaler Technique for Children?

Inhaler technique failure is the most common reason asthma is poorly controlled. Pressurized metered-dose inhalers (pMDI) must be used with a spacer in all children under 5, and are recommended with a spacer up to age 8–10.

Using a pMDI with spacer:

1. Shake the inhaler well.
2. Attach the inhaler to the spacer. Place the facemask or mouthpiece on the child’s face/mouth with a good seal.
3. Press the inhaler canister down once.
4. Ask the child to breathe in and out slowly and normally for 5–6 breaths.
5. Wait 60 seconds before a second puff.
6. Rinse the child’s mouth with water after each use of an inhaled steroid.

Common technique errors: Multiple puffs at once, no spacer used, not shaking the inhaler, not sealing the mask to the face, breathing too fast.

Ask the pediatrician or pharmacist to check inhaler technique at every review visit.

What Is the Difference Between Controller and Reliever Medications?

Reliever medications (rescue medications) work within minutes to reverse bronchospasm. They are used for acute symptoms. Salbutamol (albuterol) pMDI is the standard reliever.

• Used at first sign of wheeze or breathing difficulty
• Provide rapid symptom relief but do not treat the underlying inflammation
• If reliever is needed more than 2 times per week (not counting pre-exercise doses), asthma is not controlled and a controller medication review is needed

Controller medications reduce airway inflammation and prevent symptoms. Inhaled corticosteroids (ICS) — such as beclomethasone, fluticasone, or budesonide — are the most effective controllers available.

• Taken daily, every day, even when symptoms are absent
• Do not cause significant growth suppression at standard pediatric doses when used correctly
• Require weeks of consistent use to achieve full effect
• Should not be stopped without pediatrician advice

Leukotriene receptor antagonists (montelukast) can be added for allergic asthma or used alone in mild cases. Long-acting bronchodilators are used in older children with inadequately controlled moderate-to-severe asthma.

How Should Asthma Be Managed at School in Nepal?

Every child with asthma should have a written asthma action plan that teachers and school health workers can follow. The plan should include:

• The child’s name and photo
• Daily controller medication details
• Reliever inhaler name, dose, and instructions
• Signs of a mild, moderate, and severe attack
• What the school should do in each scenario
• Emergency contact numbers and the nearest hospital (A&B International Hospital, +977 061-412512)

Schools should hold a spare reliever inhaler with spacer in the health room for the child. Teachers should be trained to recognize and respond to an asthma attack.

What Are Pokhara’s Air Quality Considerations for Children With Asthma?

Pokhara generally has better air quality than Kathmandu due to lower vehicle density and proximity to Phewa Lake. However, during dry season (October–April), dust from construction activity, vehicle exhaust on the Prithvi Highway corridor, and open burning of agricultural residue increase PM2.5 levels measurably.

Children with asthma in Pokhara should:

• Check local air quality forecasts during dry season
• Avoid outdoor exercise on visibly dusty or smoky days
• Keep windows closed on high-traffic road-facing sides of the home during peak hours
• Use a dust mite–proof mattress cover — Pokhara’s humidity supports mite populations year-round
