Asthma in Islamabad: Symptoms, Causes, Diagnosis & Treatment

By Islamabad Respiratory Clinic (IRC), G-11 Markaz, Islamabad · Medically reviewed by Dr Muhammad Israr & Dr Jehangir Khan

Asthma is a common chronic airway disease that can cause recurrent cough, wheezing, chest tightness and shortness of breath. Symptoms can change from day to day and may become worse after exposure to pollen, dust, smoke, air pollution, cold air, exercise or respiratory infections.

For people living in Islamabad and Rawalpindi, seasonal pollen and environmental exposures can be particularly important. Islamabad has well-documented seasonal paper mulberry pollen exposure, and published research has found an association between paper mulberry pollen concentrations and asthma exacerbations among sensitised patients.

This guide explains what asthma is, common asthma triggers in Islamabad, symptoms that should not be ignored, how asthma is diagnosed, what spirometry and FeNO testing can tell you, the role of allergy testing, and how modern asthma treatment is planned.

What Is Asthma?

Asthma is a chronic respiratory disease involving inflammation and narrowing of the airways. The symptoms and degree of airflow limitation can vary over time.

Typical asthma symptoms include wheezing, shortness of breath, chest tightness and cough. Some people have symptoms every day, while others may have symptoms only during particular seasons or after specific triggers.

Asthma is not simply "a cough" and not every person with recurrent cough has asthma. Conditions such as allergic rhinitis, post-nasal drip, gastroesophageal reflux, COPD, bronchiectasis, vocal-cord disorders and some heart conditions can produce similar respiratory symptoms.

What Are the Symptoms of Asthma?

Asthma symptoms vary considerably between patients. Some people experience occasional episodes, while others have persistent symptoms.

Common symptoms include:

• Wheezing or a whistling sound while breathing
• Shortness of breath
• Chest tightness or heaviness
• Recurrent cough
• Cough that is worse at night or early morning
• Breathlessness during exercise
• Symptoms after exposure to dust, smoke or pollen
• Symptoms that worsen during respiratory infections
• Repeated episodes that improve and then return

Some patients mainly have cough rather than obvious wheezing. This can make the diagnosis more difficult and may require pulmonary function testing and consideration of other possible causes.

Why Can Asthma Symptoms Become Worse in Islamabad?

Asthma triggers differ from person to person. Islamabad's environment can expose susceptible people to several potential respiratory irritants and allergens.

1. Seasonal pollen

Seasonal pollen is an important concern in Islamabad, particularly for people who are sensitised to specific pollens. Paper mulberry pollen is especially well known in the Islamabad region.

2. Traffic-related air pollution

Vehicle emissions and particulate pollution can irritate the airways and may aggravate respiratory symptoms in susceptible individuals.

3. Dust and construction activity

Road dust, construction dust and other airborne particles can irritate sensitive airways. Dust can also contain allergens such as dust-mite particles and other substances capable of provoking symptoms.

4. Smoke and burning

Tobacco smoke, biomass burning, garbage burning and other forms of smoke exposure can irritate the respiratory tract and may worsen asthma.

5. Cold air and weather changes

Cold or rapidly changing weather can trigger symptoms in some people with asthma, particularly during exercise or outdoor exposure.

6. Indoor allergens

Dust mites, mould and animal allergens can contribute to symptoms in sensitised individuals. Indoor exposures may become particularly relevant when a person spends long periods inside the home or workplace.

7. Respiratory infections

Viral respiratory infections can trigger asthma symptoms or acute worsening of established asthma.

8. Exercise

Exercise can provoke airway narrowing in some people with asthma. Exercise-related symptoms do not necessarily mean that a person should avoid physical activity; rather, asthma control and appropriate treatment should be assessed.

Paper Mulberry Pollen and Asthma in Islamabad

Paper mulberry (Broussonetia papyrifera) pollen is a particularly relevant seasonal allergen in Islamabad.

A published observational study examined paper mulberry pollen levels and asthma exacerbations in Islamabad. The researchers found a strong positive correlation between pollen concentrations and asthma exacerbations among patients sensitised to paper mulberry. The study also observed worsening peak-flow measurements with increasing pollen concentrations in sensitised patients with asthma.

The findings support an important clinical message: not everyone with asthma will necessarily react to paper mulberry pollen, but sensitised patients may experience significant seasonal worsening.

If your asthma repeatedly becomes worse during the Islamabad pollen season, an appropriate allergy assessment may help identify whether a specific allergen is clinically relevant to your symptoms.

How Is Asthma Diagnosed?

Asthma diagnosis is based on two important elements:

1. A history of characteristic respiratory symptoms that vary over time and intensity.
2. Objective evidence of variable expiratory airflow limitation when appropriate testing is available.

Spirometry with bronchodilator responsiveness is one of the most commonly used objective tests. Depending on the patient and the circumstances, other investigations may also be appropriate.

A single normal breathing test does not automatically exclude asthma because asthma is a variable disease. If the clinical suspicion remains high, the doctor may consider repeat testing, peak-flow monitoring, bronchial challenge testing or other investigations.

Asthma Tests Available at IRC

At Islamabad Respiratory Clinic, respiratory assessment may include objective testing selected according to the patient's symptoms and clinical history.

Spirometry for Asthma

Spirometry is one of the most important objective tests used in the evaluation of asthma.

It measures how much air a person can exhale and how quickly that air can be expelled. Important measurements include:

• FEV1: forced expiratory volume in the first second.
• FVC: forced vital capacity.
• FEV1/FVC: the ratio used to assess airflow obstruction.

For suspected asthma, spirometry may be performed before and after a bronchodilator. Improvement in airflow after bronchodilator administration can provide objective evidence supporting variable airflow limitation.

Spirometry is not only useful for diagnosis. It can also help monitor lung function over time and investigate alternative diagnoses when the clinical picture is not typical of asthma.

What Is FeNO Testing?

FeNO stands for fractional exhaled nitric oxide. It is a non-invasive breath test used to estimate certain types of airway inflammation.

A raised FeNO can support the presence of Type 2 airway inflammation in a patient with compatible asthma symptoms. It may also help clinicians assess treatment response and asthma phenotype in selected patients.

However, FeNO should not be interpreted in isolation. A high FeNO is not exclusive to asthma, and a normal FeNO does not rule asthma out.

Allergy Testing, IgE and Eosinophils

Allergy testing

Allergy testing can identify sensitisation to specific allergens. Depending on the clinical situation, testing may involve skin-prick testing or blood testing for allergen-specific IgE.

The important distinction is that a positive allergy test does not automatically prove that the allergen is causing a patient's asthma symptoms. The result should fit the patient's history and exposure pattern.

Serum IgE

Total serum IgE can be elevated in people with allergic disease, but it is not by itself a diagnostic test for asthma.

Allergen-specific IgE testing may provide more specific information when an allergic trigger is suspected.

Blood eosinophils

Blood eosinophils can provide information about inflammatory phenotype. Higher eosinophil levels may support a Type 2 or eosinophilic asthma phenotype in the appropriate clinical setting.

Current asthma guidance emphasizes that biomarkers such as FeNO and blood eosinophils can support diagnosis or phenotyping in selected patients, but neither a high nor low result should be interpreted independently of the clinical picture.

Asthma Treatment

Asthma treatment is individualized. The appropriate treatment depends on age, symptoms, exacerbation history, lung function, risk factors, inflammatory phenotype, inhaler technique, adherence and other medical conditions.

Modern asthma management focuses on controlling airway inflammation, reducing symptoms and preventing exacerbations rather than simply treating symptoms whenever they appear.

Key components of asthma management may include:

• Appropriate inhaled anti-inflammatory treatment
• Reliever medication when prescribed and appropriate
• Correct inhaler technique
• Regular assessment of asthma control
• Identification and reduction of relevant triggers
• Smoking and second-hand smoke avoidance
• Management of allergic rhinitis and other associated conditions
• Vaccination where clinically appropriate
• Written asthma action planning for appropriate patients
• Regular review when symptoms remain uncontrolled

Treatment should not be selected solely because a patient has cough or wheeze. A correct diagnosis and assessment of severity and risk are important before long-term treatment is adjusted.

Why Are Inhalers Important in Asthma?

Inhaled medicines deliver medication directly to the airways and are central to modern asthma management.

Many patients are concerned that inhalers are addictive or that using an inhaler means their disease is becoming "severe." These are common misconceptions.

The safety and effectiveness of an inhaler depend on using the correct medication, dose, device and technique for the individual patient.

Poor inhaler technique can result in much less medicine reaching the lungs. For this reason, inhaler technique should be checked periodically rather than assuming that a patient is using the device correctly.

How Can You Reduce Asthma Triggers in Islamabad?

You cannot eliminate every environmental trigger, but you can reduce exposure to triggers that are relevant to you.

During high-pollen periods

• Keep windows closed when outdoor pollen exposure is particularly high if this helps your symptoms.
• Shower and change clothes after prolonged outdoor exposure if pollen is a known trigger.
• Avoid unnecessary outdoor exposure during periods when symptoms consistently worsen.
• Follow your prescribed asthma treatment plan rather than relying only on emergency reliever medication.

For dust exposure

• Reduce indoor dust accumulation.
• Wash bedding regularly.
• Consider appropriate dust-mite control if testing or history suggests dust-mite allergy.
• Use respiratory protection when exposure to heavy dust cannot be avoided.

For smoke exposure

• Do not smoke indoors.
• Avoid second-hand tobacco smoke.
• Avoid exposure to unnecessary burning of waste or biomass.
• Reduce exposure to heavy traffic pollution where practical.

For mould

• Address water leakage and dampness.
• Improve ventilation in areas prone to condensation.
• Remove visible mould appropriately and safely.

Asthma and Allergic Rhinitis Often Occur Together

People with asthma may also have allergic rhinitis, sinus symptoms or recurrent nasal congestion.

Symptoms such as sneezing, itchy nose, watery eyes, nasal blockage and post-nasal drainage can coexist with lower-airway symptoms. If nasal disease is not recognized, a patient may continue to experience respiratory symptoms despite asthma treatment.

For this reason, asthma assessment should consider the patient's complete upper and lower respiratory history rather than looking only at the lungs.

Asthma, Exercise and Physical Activity

Asthma does not automatically mean that a person should avoid exercise.

Some patients experience exercise-induced bronchoconstriction, particularly when asthma is not adequately controlled. Appropriate assessment and treatment can allow many people with asthma to remain physically active.

If you repeatedly develop cough, wheezing or chest tightness during or after exercise, discuss these symptoms with a respiratory physician rather than simply stopping physical activity.

Asthma in Children and Adults

Asthma can occur at any age. Children may present with recurrent wheezing or cough, while adults may develop symptoms later in life.

The diagnosis can sometimes be challenging in young children because reliable lung-function testing may not always be possible. In older children and adults, objective lung-function testing becomes increasingly useful when available and clinically appropriate.

A recurrent cough should not automatically be labelled asthma without considering other possible causes.

When Should You See a Pulmonologist for Asthma?

A specialist respiratory assessment may be appropriate if you have:

• Repeated wheezing
• Breathlessness that keeps returning
• Night-time cough or breathlessness
• Exercise-related respiratory symptoms
• Repeated need for nebulisation
• Repeated courses of oral steroids
• Frequent emergency visits because of breathing problems
• Symptoms that return every pollen season
• Persistent symptoms despite using an inhaler
• Uncertainty about whether you actually have asthma
• Abnormal spirometry or other pulmonary-function results

When Is Asthma an Emergency?

A severe asthma attack can become life-threatening.

Seek urgent medical attention if breathing becomes severely difficult, symptoms are rapidly worsening, you are unable to speak normally because of breathlessness, you become unusually drowsy or confused, or your prescribed reliever treatment is not providing adequate relief.

Do not delay emergency care while waiting for a routine clinic appointment if severe breathing difficulty is occurring.

Asthma Is Not Always the Same as Allergy

Asthma and allergy are closely related in many patients, but they are not identical conditions.

Some people have allergic asthma, while others have asthma without demonstrable allergic sensitisation. Conversely, a person can have allergic rhinitis without having asthma.

This is why allergy testing should be performed when clinically indicated rather than assuming that every asthma patient has an allergy.

Can Asthma Be Completely Cured?

Asthma is generally considered a chronic respiratory condition rather than a disease for which a universal permanent cure exists.

However, good asthma control is achievable for many patients. Some people may have long periods with few or no symptoms, while others require ongoing controller treatment.

The goal is to achieve good symptom control, reduce future risk and allow the patient to live an active life with the minimum effective treatment needed.
