Asthma: Symptoms, Causes, Treatment and When to Seek Emergency Medical Care

Introduction

Asthma is one of the most common chronic respiratory conditions worldwide, affecting both children and adults. It is characterised by chronic inflammation of the airways, causing them to become overly sensitive to various triggers. During an asthma flare-up, the muscles surrounding the airways tighten, the lining of the airways becomes swollen, and excess mucus is produced, making breathing difficult.

The severity of asthma varies considerably. Some people experience only occasional mild symptoms, while others have persistent asthma that requires long-term treatment. Without appropriate management, asthma can significantly affect quality of life, interfere with work, exercise and sleep, and in severe cases become life-threatening.

Many factors can trigger asthma symptoms, including viral infections, allergies, exercise, cold air, air pollution, smoke and emotional stress. Identifying these triggers and maintaining good asthma control are key components of successful management.

Whether you live in Mallorca or are visiting the island, recognising asthma symptoms and understanding when urgent medical assessment is required can help prevent serious complications and ensure timely treatment.

What Is Asthma?

Asthma is a chronic inflammatory disease of the airways.

In people with asthma, the bronchial tubes become inflamed and overly responsive to certain triggers. When exposed to these triggers, several changes occur simultaneously:

• The muscles around the airways tighten (bronchospasm).
• The airway lining becomes swollen.
• Excess mucus is produced.
• Airflow becomes restricted.

These changes make it difficult to move air in and out of the lungs, resulting in the characteristic symptoms of asthma.

Unlike chronic obstructive pulmonary disease (COPD), the airway narrowing in asthma is usually reversible, either spontaneously or with appropriate treatment.

Types of Asthma

Asthma is not a single disease. Several different forms exist, each with distinct characteristics.

Allergic Asthma

Allergic asthma is the most common type.

Symptoms are triggered by exposure to allergens such as:

• Pollen.
• House dust mites.
• Animal dander.
• Mould spores.

Many patients also have hay fever or eczema.

Non-Allergic Asthma

Some individuals develop asthma without obvious allergic triggers.

Symptoms may be provoked by:

• Viral respiratory infections.
• Cold air.
• Air pollution.
• Strong odours.
• Emotional stress.
• Certain medications.

Exercise-Induced Bronchoconstriction

Some people develop asthma symptoms mainly during or shortly after physical activity.

Typical symptoms include:

• Cough.
• Wheezing.
• Chest tightness.
• Shortness of breath.

Symptoms usually improve with rest or appropriate inhaler treatment.

Occupational Asthma

Exposure to substances in the workplace may trigger asthma.

Examples include:

• Flour dust.
• Chemical vapours.
• Wood dust.
• Latex.
• Animal proteins.

Symptoms often improve during holidays or periods away from work.

Severe Asthma

A small proportion of patients have severe asthma that remains poorly controlled despite appropriate treatment.

These individuals often require specialist assessment and advanced therapies.

Common Causes and Triggers

Asthma symptoms are triggered by inflammation combined with exposure to certain environmental or physical factors.

Common triggers include:

Respiratory Infections

• Common cold.
• Influenza.
• COVID-19.
• Other viral infections.

Respiratory viruses are among the most frequent causes of asthma exacerbations.

Allergens

Common allergens include:

• Grass pollen.
• Olive tree pollen.
• Dust mites.
• Cats.
• Dogs.
• Mould.

Exercise

Physical exertion, particularly in cold or dry air, may provoke asthma symptoms.

Cold Air

Breathing cold air may irritate sensitive airways and trigger bronchospasm.

Air Pollution

Exposure to:

• Traffic pollution.
• Wildfire smoke.
• Industrial pollution.
• Ozone.
• Fine particulate matter.

may worsen asthma control.

Tobacco Smoke

Both active smoking and passive smoke exposure significantly worsen asthma.

Strong Odours

Examples include:

• Perfumes.
• Cleaning products.
• Paint fumes.
• Aerosols.

Emotional Stress

Although stress does not cause asthma, it can worsen symptoms in susceptible individuals.

Certain Medications

Some patients experience asthma symptoms after taking:

• Aspirin.
• Non-steroidal anti-inflammatory drugs (NSAIDs).
• Beta-blockers.

This occurs only in susceptible individuals.

Risk Factors

Factors associated with an increased likelihood of developing asthma include:

• Family history of asthma.
• Allergic rhinitis (hay fever).
• Eczema.
• Childhood allergies.
• Exposure to tobacco smoke.
• Air pollution.
• Obesity.
• Occupational exposure to respiratory irritants.
• Premature birth.

Not every person with these risk factors will develop asthma.

Common Symptoms

Asthma symptoms vary between individuals and may fluctuate over time.

Common symptoms include:

Respiratory Symptoms

• Wheezing.
• Shortness of breath.
• Chest tightness.
• Persistent cough.
• Difficulty breathing deeply.

Night-Time Symptoms

Many patients notice symptoms that are worse:

• During the night.
• Early in the morning.
• After exercise.
• During allergy season.

Night-time symptoms often indicate poor asthma control.

During an Asthma Attack

Symptoms may include:

• Rapid breathing.
• Difficulty speaking in full sentences.
• Audible wheezing.
• Persistent coughing.
• Chest tightness.
• Use of neck and chest muscles to breathe.
• Anxiety due to breathlessness.

Severe attacks require immediate medical assessment.

When Should You Seek Emergency Medical Care?

Asthma symptoms can range from mild wheezing to severe, life-threatening breathing difficulties.

Seek immediate emergency medical attention if you experience:

• Severe shortness of breath.
• Difficulty speaking in full sentences due to breathlessness.
• Rapid worsening of wheezing.
• Chest tightness that is becoming increasingly severe.
• Blue lips or fingertips (cyanosis).
• Confusion or drowsiness.
• Collapse or loss of consciousness.
• Little or no improvement after using your prescribed reliever inhaler.
• Needing your reliever inhaler much more frequently than usual during an acute attack.

These symptoms may indicate a severe asthma attack, which requires urgent medical treatment.

Delaying emergency care may result in respiratory failure and other serious complications.

When Should You Arrange a Medical Assessment?

Medical assessment is recommended if:

• You experience wheezing for the first time.
• You have persistent coughing lasting several weeks.
• Breathlessness occurs repeatedly during exercise.
• Symptoms regularly wake you during the night.
• You frequently require your reliever inhaler.
• Asthma symptoms interfere with work, sleep or daily activities.
• Symptoms become progressively more frequent.
• You have repeated chest infections.
• You suspect allergies are triggering your symptoms.

Good asthma control aims to minimise symptoms, reduce the risk of severe attacks and maintain normal daily activities.

How Is Asthma Evaluated?

Diagnosis begins with a detailed medical history.

Your doctor may ask questions such as:

• When did your symptoms begin?
• What triggers your symptoms?
• Do symptoms occur during exercise?
• Are symptoms worse at night?
• Do you have allergies, eczema or hay fever?
• Is there a family history of asthma?
• Have you ever smoked?
• Have you recently had a respiratory infection?
• Which medications have you used?
• Have you ever required emergency treatment for breathing difficulties?

The pattern of symptoms often provides important clues regarding the diagnosis.

Physical Examination

A comprehensive examination may include:

• Measurement of blood pressure.
• Heart rate.
• Respiratory rate.
• Oxygen saturation.
• Temperature.
• Examination of the nose and throat.
• Listening to the lungs with a stethoscope.
• Assessment for wheezing.
• Evaluation of breathing effort.
• Examination for signs of allergic disease such as eczema or allergic rhinitis.

During mild asthma, the examination may be completely normal between episodes.

Additional Investigations

Further investigations help confirm the diagnosis and assess asthma severity.

These may include:

• Spirometry (lung function testing).
• Peak expiratory flow measurement.
• Bronchodilator reversibility testing.
• Fractional exhaled nitric oxide (FeNO) testing where available.
• Allergy testing.
• Chest X-ray when another diagnosis is suspected.
• Blood tests in selected patients.

Lung function testing is one of the most important investigations for confirming asthma.

Treatment for Asthma

Treatment depends on symptom frequency, severity and individual risk factors.

The goals of treatment are to:

• Control symptoms.
• Prevent asthma attacks.
• Maintain normal lung function.
• Allow normal physical activity.
• Reduce the need for emergency care.

Reliever Inhalers

Reliever inhalers are used to rapidly relieve symptoms during an asthma attack.

These medications relax the muscles surrounding the airways, allowing airflow to improve within minutes.

They should be used exactly as prescribed.

Frequent reliance on a reliever inhaler may indicate that asthma is not well controlled and should prompt medical review.

Preventer Inhalers

Preventer inhalers contain anti-inflammatory medication that reduces chronic airway inflammation.

Regular use helps:

• Reduce symptoms.
• Prevent asthma attacks.
• Improve lung function.
• Decrease the need for reliever medication.

Unlike reliever inhalers, preventers must be taken consistently, even when symptoms are absent.

Combination Inhalers

Some patients benefit from inhalers containing both:

• An inhaled corticosteroid.
• A long-acting bronchodilator.

These medications provide ongoing control while helping prevent asthma exacerbations.

The most appropriate inhaler depends on the individual's asthma severity and current clinical guidelines.

Management of Severe Asthma

Patients with severe asthma may require additional treatments, including:

• Specialist respiratory assessment.
• Biological therapies.
• Short courses of oral corticosteroids during severe flare-ups.
• Treatment of associated allergic disease.
• Individualised asthma action plans.

Most people with asthma do not require these advanced therapies.

Lifestyle Measures That Help Control Asthma

Medication is only one aspect of asthma management.

Additional measures include:

• Avoiding tobacco smoke.
• Identifying and reducing exposure to personal triggers.
• Managing allergies.
• Maintaining a healthy weight.
• Receiving recommended vaccinations.
• Exercising regularly when asthma is well controlled.
• Learning correct inhaler technique.
• Following a personalised asthma action plan.

Good long-term control greatly reduces the likelihood of severe asthma attacks.

Common Myths About Asthma

Myth 1: Asthma only affects children.

False.

Asthma can develop at any age. Many adults receive their first diagnosis during adulthood.

Myth 2: If symptoms disappear, asthma has been cured.

False.

Asthma symptoms often fluctuate.

Even when symptoms are absent, underlying airway inflammation may persist, making continued treatment important for many patients.

Myth 3: People with asthma should avoid exercise.

False.

Most people with well-controlled asthma can participate fully in physical activity.

Regular exercise is encouraged once asthma is appropriately managed.

Myth 4: Inhaled corticosteroids are dangerous.

False.

When used at the prescribed dose, inhaled corticosteroids are considered safe and are one of the most effective treatments for preventing asthma attacks.

The benefits of good asthma control greatly outweigh the risk of side effects for most patients.

Myth 5: Using a reliever inhaler several times every day is normal.

False.

Frequent need for a reliever inhaler usually indicates poor asthma control and should prompt a medical review to optimise treatment.

Medical Assessment for Asthma at Dr. Indhira Ghyssaert's Practice in Mallorca

At Dr. Indhira Ghyssaert's practice in Mallorca, patients presenting with asthma symptoms receive a comprehensive medical assessment to confirm the diagnosis, evaluate symptom control and identify factors that may be contributing to airway inflammation.

Because wheezing, cough and shortness of breath may also be caused by respiratory infections, chronic obstructive pulmonary disease (COPD), heart disease, anxiety, allergies or other medical conditions, establishing an accurate diagnosis is essential before initiating or modifying treatment.

The assessment focuses not only on relieving current symptoms but also on preventing future asthma attacks and improving long-term respiratory health.

Depending on the patient's symptoms and clinical findings, the assessment may include:

• A detailed medical history.
• Review of asthma symptoms and known triggers.
• Assessment of previous asthma attacks and hospital admissions.
• Measurement of vital signs, including oxygen saturation.
• Examination of the chest and respiratory system.
• Assessment for associated allergic conditions such as hay fever or eczema.
• Blood tests when clinically indicated.
• Referral for lung function testing or specialist respiratory assessment when appropriate.
• Evaluation of inhaler technique and current medication use.

Treatment recommendations are individualised according to current evidence-based clinical guidelines and each patient's level of asthma control.

Management may include optimising inhaler therapy, trigger avoidance strategies, treatment of associated allergic conditions and referral to a respiratory specialist when clinically indicated.

The primary objective is to achieve excellent symptom control while reducing the risk of future exacerbations and preserving long-term lung function.

Asthma While Visiting Mallorca

Travelling can sometimes increase the likelihood of asthma symptoms.

Changes in climate, pollen exposure, respiratory infections, exercise, air pollution and unfamiliar environmental allergens may all trigger asthma in susceptible individuals.

Although Mallorca generally has good air quality, seasonal pollen levels—particularly from grasses, olive trees and cypress—may contribute to symptoms in people with allergic asthma.

Visitors should ensure they:

• Carry their prescribed inhalers at all times.
• Continue their regular asthma medication.
• Avoid known triggers whenever possible.
• Seek prompt medical attention if symptoms worsen or do not respond to their usual treatment.

Immediate medical assessment is essential if breathing becomes progressively more difficult or symptoms fail to improve after using a reliever inhaler.

Frequently Asked Questions

Can asthma develop in adulthood?

Yes.

Although asthma commonly begins during childhood, many people develop asthma for the first time as adults. Adult-onset asthma is particularly common in individuals with allergies, occupational exposures or following certain respiratory infections.

Is asthma curable?

There is currently no cure for asthma.

However, with appropriate treatment and regular medical follow-up, most people achieve excellent symptom control and lead active, healthy lives.

Can asthma worsen during allergy season?

Yes.

Many individuals have allergic asthma, in which exposure to pollen, dust mites, mould or animal dander triggers airway inflammation and worsening symptoms.

Good allergy management often improves asthma control.

Can exercise trigger asthma?

Yes.

Exercise-induced bronchoconstriction is common, particularly during vigorous activity or in cold, dry air.

Most people can continue exercising safely once their asthma is well controlled and appropriate treatment is in place.

Is asthma contagious?

No.

Asthma is not an infectious disease and cannot be passed from one person to another.

However, viral respiratory infections that trigger asthma flare-ups can be contagious.

Why is correct inhaler technique important?

Even highly effective medications may not work properly if the inhaler is used incorrectly.

Regular review of inhaler technique helps ensure that medication reaches the lungs effectively and improves asthma control.

Key Takeaways

• Asthma is a chronic inflammatory disease of the airways that causes reversible narrowing of the bronchial tubes.
• Common symptoms include wheezing, cough, chest tightness and shortness of breath.
• Viral infections, allergens, exercise, cold air and smoke are among the most common triggers.
• Severe breathlessness, inability to speak in full sentences or poor response to a reliever inhaler require immediate emergency medical attention.
• Long-term asthma control depends on accurate diagnosis, appropriate medication, trigger management and regular medical follow-up.

Conclusion

Asthma is a common but potentially serious respiratory condition that requires accurate diagnosis and appropriate long-term management.

Although many people experience only occasional symptoms, poorly controlled asthma increases the risk of severe attacks, hospitalisation and reduced quality of life.

A comprehensive medical assessment helps confirm the diagnosis, identify individual triggers and develop a personalised treatment plan that minimises symptoms while reducing the risk of future exacerbations.
