The 41 pages that link to Chronic obstructive pulmonary disease, each with the reason it gives.

• AsthmaCompared with: Its usually persistent obstruction contrasts with asthma’s often variable airflow limitation.

• Smoking cessationRelated: Cessation slows further smoke-related lung damage, though existing disease may remain.

• Mucociliary clearanceRelated: Airway inflammation and structural changes can impair mucus transport in this disease.

• LungRelated: It damages airways or alveoli and makes breathing out difficult.

• Respiratory systemRelated: It shows how long-term airway and alveolar damage can impair ventilation and gas exchange.

• Tobacco smokingRelated: Long-term smoking is a leading cause of this persistent respiratory impairment.

• Acute respiratory distress syndromeCompared with: Its defining problem is chronic airflow obstruction, unlike ARDS’s acute injury and oxygenation failure.

• SpirometryRelated: Spirometry is central to confirming persistent airflow obstruction in suspected COPD.

• Oxygen therapyRelated: Some people with advanced disease benefit from long-term oxygen when blood oxygen is chronically low.

• N-acetylcysteineRelated: Inhaled or oral N-acetylcysteine has been studied and used as a mucus-thinning adjunct.

• Occupational asthmaCompared with: Its typically persistent airflow obstruction differs from asthma's variable, often reversible narrowing.

• Respiratory failureBroader topic: It is a common underlying disease that can cause chronic or acute-on-chronic failure.

• Ventilation–perfusion mismatchRelated: Airway obstruction and vascular destruction create uneven ventilation and perfusion.

• Pulmonary fibrosisCompared with: Its airflow obstruction differs from the restrictive pattern typical of pulmonary fibrosis.

• Pulmonary function testingBroader topic: Spirometry is used to establish airflow obstruction and assess its severity.

• Inhaled corticosteroidRelated: In selected patients, inhaled corticosteroids are added to reduce exacerbations.

• Interstitial lung diseaseCompared with: Unlike typical ILD, it primarily obstructs airflow rather than restricting lung expansion.

• Pulmonary rehabilitationBroader topic: It is the best-studied indication and a common reason for referral.

• BronchoconstrictionCompared with: Its persistent airflow limitation contrasts with episodic bronchoconstriction.

• BronchospasmRelated: Some people with COPD experience reversible bronchospasm during symptom flare-ups.

• CyanosisRelated: Advanced disease can reduce arterial oxygen enough to produce central cyanosis.

• EmphysemaNarrower topic: Emphysema is one of the structural diseases grouped under COPD.

• Tobacco smokeRelated: Long-term tobacco smoke exposure is its leading cause.

• PulmonologyRelated: COPD is a common cause of persistent breathlessness and a major focus of pulmonary care.

• Respiratory syncytial virusRelated: RSV can precipitate serious exacerbations in people with chronic obstructive pulmonary disease.

• TheophyllineRelated: Theophylline has sometimes been used as an add-on bronchodilator in COPD.

• Alpha-1 antitrypsin deficiencyNarrower topic: Alpha-1 antitrypsin deficiency is an inherited cause of obstructive lung disease.

• BronchodilatorRelated: Long-acting bronchodilators are central to symptom control in this disease.

• CigaretteRelated: Cigarette smoke is the leading cause of COPD in many populations.

• InhalerRelated: Bronchodilators and other inhaled medicines help manage its symptoms and exacerbations.

• BronchitisNarrower topic: Chronic bronchitis is one clinical form within this broader disease group.

• Haemophilus influenzaeRelated: Nontypeable H. influenzae can colonize airways and contribute to exacerbations.

• Chlamydia pneumoniaeRelated: C. pneumoniae has been investigated in relation to chronic airway disease, but its causal role remains uncertain.

• AcetylcysteineRelated: Acetylcysteine is used in some patients to help manage chronic mucus and exacerbations.

• Bronchiolitis obliteransCompared with: It also causes persistent obstruction, but typically involves broader airway and lung-tissue changes.

• Respiratory diseaseBroader topic: It contrasts with episodic obstruction through persistent limitation of airflow.

• SalbutamolRelated: Salbutamol can relieve reversible bronchoconstriction and breathlessness in this condition.

• SalmeterolRelated: Salmeterol can provide sustained bronchodilation for COPD symptoms.

• Health effects of smoking tobaccoBroader topic: Tobacco smoke is the main cause of COPD in many populations.

• Respiratory tract infectionCompared with: It can worsen during infection, yet it is a chronic disease rather than an infection.

• Shortness of breathBroader topic: Air trapping and reduced airflow often make breathing difficult, especially during exertion.
