by What are Asthma and COPD?
Both asthma and chronic obstructive pulmonary disease (COPD) are conditions that affect the lungs and make breathing difficult. However, there are some key differences between the two diseases that are important to understand.
Asthma
Asthma is a chronic lung disease characterized by inflammation and narrowing of the airways. The inflammation causes the muscles around the airways to tighten, reducing the size of the airways and causing wheezing, coughing, chest tightness and shortness of breath. Asthma episodes or attacks can range from mild to life-threatening. Some common triggers that can cause an asthma attack include allergens, exercise, cold air, smoke and infections.
While there is currently no cure for asthma, treatments are available to help control symptoms and prevent attacks. Daily asthma control medications like inhaled corticosteroids help reduce airway inflammation, while quick-relief inhalers containing bronchodilators are used to open airways during an attack. Most people can manage their asthma successfully with the right medication regimen and by avoiding triggers.
COPD
COPD, also known as chronic bronchitis or emphysema, refers to a group of lung diseases that cause airflow blockage and breathing-related problems. The most common cause of Asthma and COPD worldwide is long-term exposure to irritating gases or particulate matter, usually from cigarette smoke. Other less common causes include exposure to air pollution, dust or chemical fumes.
Unlike asthma, COPD gets progressively worse over time and is not fully reversible. The two main conditions that make up COPD are chronic bronchitis and emphysema. Chronic bronchitis causes a long-term cough with mucus, while emphysema damages and destroys the air sacs in the lungs. This damage to the lungs leads to a limitation of airflow both on exhaling and inhaling over many years.
Symptoms of COPD include shortness of breath, a chronic cough that may or may not produce mucus, wheezing and chest tightness. However, these symptoms typically do not appear until the lung disease is fairly serious. Treatment focuses on relieving symptoms via bronchodilators and reducing lung damage progression through smoking cessation and other medications like steroids. Lung function loss from COPD is usually not fully reversible.
Similarities and Differences
While both asthma and COPD involve airflow obstruction, there are some distinct differences:
– Asthma is generally reversible while COPD is progressive and not fully reversible. Asthma treatment relieves symptoms and prevents attacks while COPD treatment slows disease progression.
– Asthma often develops in childhood while COPD usually develops in mid-life, often in smokers over 40.
– Asthma symptoms vary over time and are often triggered by allergens, viruses or exercise. COPD symptoms gradually worsen over many years.
– In asthma, the airways narrow due to inflammation and tightening of airway muscles. In COPD, damage to lung tissues like emphysema causes permanent airflow limitation over time.
– Asthma episodes happen suddenly, while COPD develops more slowly and symptoms worsen gradually.
– Asthma can often be managed effectively with medications, while COPD has no cure and lung damage accumulates irreversibly from continued smoking or prolonged exposure.
Treating Asthma COPD
While asthma COPD are distinct conditions, they share some similarities in terms of treatment approaches. Both usually involve a combination of medications and lifestyle changes.
When it comes to medications, the following are commonly used to treat both asthma and COPD:
– Short-acting bronchodilators for quick symptom relief during asthma attacks or COPD flare-ups. Examples are albuterol and ipratropium.
– Long-acting bronchodilators for daily management. These open the airways and include drugs like salmeterol and tiotropium.
– Inhaled corticosteroids to reduce airway inflammation in asthma and lessen COPD symptoms when used with bronchodilators. Common ones are fluticasone and budesonide.
– Oral corticosteroids such as prednisone in short bursts to treat severe asthma attacks or COPD exacerbations.
Lifestyle changes helpful for both conditions include avoiding cigarette smoke and other air pollutants, getting vaccinated, managing respiratory infections promptly and following an exercise plan adapted to your lung function level. Other supportive treatments involve pulmonary rehabilitation and supplementary oxygen when oxygen levels are low.
while asthma COPD have distinctive features, an integrated approach using medications, lifestyle changes, minimising triggers and monitoring lung function overtime can help millions of people manage these common respiratory diseases effectively. With prompt treatment, the majority can live full and active lives.
