Lung diseases are diseases or disorders that can affect respiratory function, the ability to breathe, and how well the lungs work.
Some of the most common lung diseases include:
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Bronchiectasis
- Bronchitis
- Pulmonary fibrosis
- Sarcoidosis
- Lung cancer
- Pneumonia
- Pulmonary edema
- Influenza (“the flu”)
What Are Symptoms of Lung Diseases?
Symptoms of lung disease vary depending on the condition and may include:
- Cough
- Cough with phlegm
- Dry cough
- Coughing up blood
- Chronic cough
- Difficulty breathing
- Shortness of breath
- Wheezing
- Chest tightness/soreness
- Sharp chest pain that is worse when you take a breath
- Difficulty inhaling deeply
- Excess phlegm, mucus, or sputum production
- Frequent bronchitis or other lung infections
- Fever
- Weakness
- Fatigue
- Weight loss
- Loss of appetite
- Cold or flu symptoms
- Stuffy nose
- Sore throat
- Headache
- Body aches
- Swollen lymph nodes
What Causes Lung Diseases?
The cause of lung disease varies depending on the condition.
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Smoking tobacco (the main cause)
- Inhaling secondhand smoke
- Exposure to air pollutants in the home and workplace
- A history of respiratory infections
- Genetic factors, such as alpha-1 deficiency
- Bronchiectasis
- Primary bacterial or viral infections
- Bronchial obstruction
- Foreign body aspiration
- Cystic fibrosis or Young syndrome
- Primary ciliary dyskinesia
- Allergic bronchopulmonary aspergillosis (ABPA)
- Immunodeficiency states, both genetic and acquired, such as HIV/AIDS
- Congenital anatomic defects
- Connective-tissue disorders
- Alpha1-antitrypsin (AAT) deficiency
- Autoimmune diseases
- Idiopathic inflammatory disorders
- Autosomal dominant polycystic kidney disease (ADPKD)
- Traction from other processes
- Toxic gas exposure
- Bronchitis
- Acute bronchitis: caused by viruses such as the common cold, influenza, or whooping cough; sometimes caused by bacteria
- Chronic bronchitis: caused by smoking or breathing in toxic fumes or gases
- Pulmonary fibrosis
- Sarcoidosis
- It is unknown how a person gets sarcoidosis; may be a genetic component, or bacteria, viruses, or chemicals may trigger the disease
- Lung cancer
- Pneumonia
- Bacteria
- Viruses
- Fungi
- Pulmonary edema
- Congestive heart failure
- Certain medicines
- High altitude exposure
- Kidney failure
- Narrowed arteries that bring blood to the kidneys
- Lung damage caused by poisonous gas or severe infection
- Major injury
- Influenza
- Influenza virus
How Are Lung Diseases Diagnosed?
A variety of tests may be ordered to diagnose you with a lung condition such as asthma, COPD, bronchitis, lung cancer, and others. These tests may include one or more of the following:
- Pulmonary function tests
- Spirometry
- Peak expiratory flow (PEF)
- Bronchoprovocation tests
- Fractional exhaled nitric oxide (FeNO) tests
- Provocation (Trigger) Tests
- Allergy skin or blood tests, in patients who have a history of allergies
- Chest X-ray
- Arterial blood gas test to measure oxygen levels in the blood
- Bronchoscopy
- Lung tissue biopsy via bronchoscopy
- Sputum culture
- Blood tests
- Immunoglobulin levels
- Alpha1-antitrypsin (AAT) levels
- Aspergillus precipitins
- Total IgE levels
- Vitamin D levels
- Autoimmune screening tests
- Computed tomography (CT) scan of the chest
- Positron emission tomography (PET) scan
- Electrocardiogram (ECG or EKG) of the heart
What Is the Treatment for Lung Diseases?
Treatment for lung disease varies depending on the condition.
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Quitting smoking
- Avoiding secondhand tobacco smoke
- Avoiding air pollutants at home and at work
- Pulmonary rehabilitation
- Medications to treat symptoms
- Supplemental oxygen
- Bronchiectasis
- Antibiotics
- Bronchodilators
- Corticosteroids
- Chest physiotherapy
- Pulmonary rehabilitation
- Dietary supplementation
- Oxygen (reserved for hypoxemic patients with severe disease)
- Hospitalization for severe exacerbations
- Surgical therapies
- Bronchitis
