The 52 pages that link to Asthma, each with the reason it gives.

• Air pollutionRelated: Air pollutants can trigger symptoms and contribute to asthma attacks.

• Chronic obstructive pulmonary diseaseCompared with: Asthma obstruction is often more variable and reversible than the persistent limitation typical of COPD.

• AnaphylaxisCompared with: Wheezing overlaps, but isolated asthma does not account for anaphylaxis's systemic features.

• Cystic fibrosisCompared with: Both can cause breathing problems, but asthma does not produce cystic fibrosis's inherited CFTR defect.

• Allergic rhinitisRelated: The two conditions frequently coexist and can influence one another's control.

• Indoor air qualityRelated: Indoor allergens, irritants, and dampness can trigger symptoms or worsen asthma for some people.

• AllergyRelated: Allergic inflammation can contribute to asthma in some people, though asthma has other causes.

• Pulmonary edemaCompared with: Asthma causes airflow obstruction rather than fluid filling the pulmonary interstitium or alveoli.

• Respiratory systemRelated: Its airway narrowing can make breathing difficult despite structurally intact lungs.

• SpirometryRelated: Spirometry can document variable airflow limitation and response to bronchodilator treatment.

• Nitrogen dioxideRelated: NO₂ exposure can irritate airways and worsen asthma symptoms, particularly in susceptible people.

• EicosanoidRelated: Cysteinyl leukotrienes can contribute to airway narrowing and mucus production.

• PrednisoneRelated: Short courses of systemic prednisone can treat severe exacerbations.

• Occupational asthmaNarrower topic: Occupational asthma is defined by asthma arising from or worsened by workplace conditions.

• Photochemical smogRelated: Ozone and other smog pollutants can trigger symptoms and exacerbate asthma.

• Ventilation–perfusion mismatchRelated: Uneven airway narrowing produces poorly ventilated regions despite continuing blood flow.

• CoughRelated: Cough can be a prominent asthma symptom, sometimes occurring without obvious wheezing.

• Pepper sprayRelated: People with asthma may be especially vulnerable to respiratory effects of inhaled irritants.

• Indoor air pollutionRelated: Indoor allergens and irritants can trigger symptoms or worsen asthma.

• Pulmonary function testingBroader topic: Repeated airflow measurements can document variable obstruction and response to bronchodilators.

• Chronic rhinosinusitisRelated: Asthma commonly coexists with chronic rhinosinusitis and can affect treatment decisions.

• Secondhand smokeRelated: Secondhand smoke can trigger asthma symptoms and worsen control of the disease.

• Inhaled corticosteroidRelated: Inhaled corticosteroids control the persistent inflammation that contributes to asthma symptoms and attacks.

• Interstitial lung diseaseCompared with: Asthma affects the airways and often varies over time, unlike persistent interstitial scarring.

• Nasal polypsRelated: Asthma frequently coexists with nasal polyps, especially in severe inflammatory disease.

• BronchoconstrictionRelated: Bronchoconstriction contributes to asthma's episodic airflow limitation.

• BronchospasmNarrower topic: Asthma commonly causes recurrent bronchospasm through airway inflammation and hyperresponsiveness.

• EmphysemaCompared with: Its airflow obstruction is often variable and reversible, unlike the persistent structural damage of emphysema.

• Cat allergyNarrower topic: Cat allergy can trigger asthma symptoms or worsen existing asthma.

• MethylxanthineRelated: Theophylline has been used as a bronchodilator in asthma treatment.

• SmogRelated: Ozone and particles in smog can trigger symptoms and worsen asthma.

• ACE inhibitor coughCompared with: Asthma can also cause persistent cough, but often has other features such as wheeze or variable breathlessness.

• PulmonologyRelated: Pulmonologists diagnose asthma and manage its symptoms, triggers, and long-term control.

• Respiratory syncytial virusRelated: RSV can trigger wheezing and may worsen respiratory symptoms in people with asthma.

• TheophyllineRelated: Theophylline can relieve airflow limitation, though it is not usually a preferred first-line treatment.

• BronchodilatorRelated: Bronchodilators relieve reversible airflow narrowing in asthma, alongside anti-inflammatory treatment.

• Eosinophilic granulomatosis with polyangiitisRelated: Asthma often precedes systemic vasculitis in EGPA and is a defining part of its clinical pattern.

• InhalerRelated: Inhaled reliever and controller medicines are central to asthma treatment.

• TartrazineRelated: Tartrazine has been investigated as a possible trigger in some people with asthma, though evidence does not support a general effect.

• BronchitisCompared with: Asthma can resemble bronchitis but involves recurring, variable airway narrowing.

• MontelukastNarrower topic: Montelukast is used for long-term control and prevention of asthma symptoms.

• PrednisoloneRelated: Prednisolone can treat severe exacerbations by reducing airway inflammation.

• Bronchiolitis obliteransCompared with: Its variable, often reversible obstruction contrasts with the persistent obstruction of bronchiolitis obliterans.

• Respiratory diseaseBroader topic: It illustrates episodic airway obstruction that can improve spontaneously or with treatment.

• SalbutamolNarrower topic: Salbutamol can relieve acute bronchoconstriction, but it does not control underlying airway inflammation.

• SalmeterolRelated: Salmeterol is used for maintenance control, alongside inhaled corticosteroid therapy.

• Passive smokingRelated: Secondhand smoke can trigger symptoms and worsen asthma, especially in children.

• Respiratory soundsRelated: Airway narrowing during asthma can produce wheezing.

• Respiratory tract infectionCompared with: An infection may trigger asthma symptoms, but asthma itself is not an infection.

• Robert DonatRelated: Severe asthma affected Donat’s health and repeatedly interrupted his acting career.
