COPD vs. asthma quick comparison
- COPD is mainly due to damage caused by smoking, while asthma is due to an inflammatory reaction.
- COPD is a progressive disease, while allergic reactions of asthma can be reversible.
- Initial symptoms can be similar in both diseases, for example, shortness of breath, chest tightness, wheezing, and cough, which can lead to confusion or misdiagnosis.
- Both diseases can have severe, dangerous signs and symptoms, for example, a bluish discoloration of the skin, and respiratory distress. Death may even occur.
- Initial treatments of COPD include bronchodilators, while initial treatments for asthma include inhaled corticosteroids while initial treatments.
- COPD usually develops after age 40 and often becomes a chronic disease of lung function. Asthma may develop in people of almost any age.
What is COPD?
COPD (chronic obstructive pulmonary disease) is a lung disease caused by chronic interference with lung airflow that impairs breathing, and is not fully reversible. Usually symptoms, for example, shortness of breath, recurrent coughing, clearing throat, and progressive exercise tolerance, worsen over time. Many doctors and researchers (for example, the World Health Organization) consider terms such as chronic bronchitis and emphysema as forms of COPD. The major cause of COPD is smoking.
What is asthma?
Asthma is a respiratory condition marked by spasms of the bronchi, due to inflamed and narrowed airways in the lungs. Asthma causes difficulty in breathing that often results from an allergic reaction. Many substances may trigger asthma attacks. Asthma usually causes recurring periods of shortness of breath, wheezing and/or chest tightness. Often, asthma can be fully reversible with medical treatment and breathing can return to normal.
Symptoms and signs: 6 similarities between COPD vs. asthma
Similarities in signs and symptoms are between the two conditions are:
Symptoms and signs: 6 Differences between COPD vs. asthma
- In asthma, breathing can return to normal between attacks, while breathing with COPD usually does not return to normal.
- The symptoms of COPD gradually become more severe. (This also may occur if you have asthma.)
- COPD produces more mucus and phlegm compared to asthma.
- Chronic cough is common with COPD.
- People with COPD often have chronic blueness to fingernail beds and/or lips (cyanosis).
- Asthma can occur in a person of almost any age, while COPD usually occurs in those over age 40. (Although it is possible in some individuals to develop COPD a younger age.)
Causes of COPD vs. asthma
COPD is caused by long-term exposure to lung irritants that damage lung cells. The main cause of COPD in the United States is cigarette smoke followed by other tobacco smoke (including second hand smoke). Other possible causes of COPD include chemical or toxic fumes, and inherited (genetic) factors, like alpha-1 antitrypsin deficiency, but these causes are far less common than cigarette smoking.
Although cigarette smoke may trigger asthma in some patients, asthma triggers are different from person to person, and most commonly include airborne substances such as pollen, dust, mites, mold spores, pet dander, and/or many other substances. Inflammatory immune reactions to asthma triggers in the airways is the main cause of asthma.
COPD vs. asthma treatment guidelines and management
There are many treatment options and ways to manage COPD. The newest 2017 guidelines emphasize the use of combined bronchodilators as first-line therapy for COPD. Doctors recommend vaccinations for people with the condition to decrease the risk of lower respiratory tract infections. Alterations in health-related behaviors (for example, stopping smoking) is emphasized. Spirometry measurements can help determine the extent of obstructive lung disease. As COPD progresses, oxygen therapy, especially if you have obstructive sleep apnea, may help improve your survival.
Like COPD, there are many treatment options and ways to manage asthma. Your primary care doctor and/or an allergist will discuss and suggest the best choice of treatment and management drugs for you. Medications used include corticosteroids, short acting beta agonists (for example, albuterol, or Poventil and other brand names), and occasionally anticholinergic medications for severe exacerbations.
Occasionally, for long-term treatment and management of asthma, doctors will prescribe long-acting anticholinergic medications (for example, salmeterol [Servent] and formoterol [Foradil]), corticosteroids, and/or other drugs combinations of drugs. You and your allergist may need to try different drugs to find the most effective treatment for your condition. Your doctor may recommend allergy shots (immunotherapy) if you have become desensitized to certain asthma triggers.
Emergency treatment of life-threatening asthma or COPD may involve intravenous corticosteroids, intubation, mechanical ventilation, and oxygen treatment until the crisis is resolved.
What is the prognosis and life expectancy for a person COPD vs. asthma?
The prognosis for COPD ranges from fair to poor and depends on how rapidly COPD advances over time. In general, individuals with COPD have a decrease in their lifespan according to research.
If you have asthma, the prognosis for most people ranges from fair to excellent, depending upon how well you can identify what triggers your attacks, and your response to medication.

Asthma MedicationsThere are two types of asthma medications: long-term control with anti-inflammatory drugs and quick relief from bronchodilators. Asthma medicines may be inhaled using a metered-dose inhaler or nebulizer or they may be taken orally. People with high blood pressure, diabetes, thyroid disease, or heart disease shouldn't take OTC asthma drugs like Primatene Mist and Bronkaid.
Asthma OverviewAsthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.

Asthma QuizAsthma is a chronic disease of the airways of the lungs, which can be managed with proper treatment. Triggered by two main causes, asthma symptoms can be brought on by environmental factors and surprising allergens.
Asthma: Over The Counter TreatmentPatients who have infrequent, mild bouts of asthma attacks may use over-the-counter (OTC) medications to treat their asthma symptoms. OTC asthma medicines are limited to epinephrine and ephedrine. These OTC drugs are best used with the guidance of a physician, as there may be side effects and the drugs may not be very effective.
Bronchitis is inflammation of the airways in the lung. Acute bronchitis is is short in duration (10 to 20 days) in comparison with chronic bronchitis, which lasts for months to years. Causes of acute bronchitis include viruses and bacteria, which means it can be contagious. Acute bronchitis caused by environmental factors such as pollution or cigarette smoke is not contagious. Common symptoms for acute bronchitis include nasal congestion, cough, headache, sore throat, muscle aches, and fatigue.
Acute bronchitis in children also my include runny nose, fever, and chest pain. Treatment for acute bronchitis are OTC pain relievers, cough suppressants (although not recommended in children), and rest. Infrequently antibiotics may be prescribed to treat acute bronchitis.
Bronchitis PictureAcute bronchitis usually comes on quickly and gets better after several weeks. See a picture of Acute Bronchitis and learn more about the health topic.
Bronchitis SlideshowIs bronchitis contagious? Learn about bronchitis, an inflammation of the lining of the lungs. Bronchitis can be aggravated from colds, cigarette smoking, COPD, and other lung conditions. Explore bronchitis symptoms and treatments.
Bronchitis QuizWhat happens within the body when a person develops bronchitis? Take this quick quiz to learn the causes, symptoms, treatments, and complications of this common respiratory illness.
Chronic bronchitis is a cough that occurs daily with production of sputum that lasts for at least three months, two years in a row. Causes of chronic bronchitis include cigarette smoking, inhaled irritants, and underlying disease processes (such as asthma, or congestive heart failure). Symptoms include cough, shortness of breath, and wheezing. Treatments include bronchodilators and steroids. Complications of chronic bronchitis include COPD and emphysema.
COPD (Chronic Obstructive Pulmonary Disease)COPD or chronic obstructive pulmonary disease is a lung condition caused by smoking tobacco, exposure to secondhand smoke, and/or air pollutants. Conditions that accompany COPD include chronic bronchitis, chronic cough, and emphysema. Symptoms of COPD include shortness of breath, wheezing, and chronic cough. Treatment of COPD include GOLD guidelines, smoking cessation, medications, and surgery. The life expectancy of a person with COPD depends on the stage of the disease.
COPD QuizCOPD is a combination of three conditions? Take this quiz to learn the three conditions that make up the pulmonary disease called chronic obstructive pulmonary disease (COPD).
COPD SlideshowCOPD is a pulmonary disorder caused by obstructions in the airways of the lungs leading to breathing problems. Learn about COPD symptoms, diagnosis, and treatment options. COPD may be complicated by chronic bronchitis or emphysema.
COPD vs. Emphysema Differences SimilaritiesCOPD (chronic obstructive pulmonary disease) is the term doctors and other healthcare professionals use to describe a group of serious, progressive (worsens over time), chronic lung diseases that include emphysema, chronic bronchitis, and sometimes asthma. The number one cause of COPD or emphysema, is smoking, and smoking is the third leading cause of death in the US.
Emphysema (Lung Condition)Emphysema is a COPD (chronic obstructive pulmonary disease) that often occurs with other obstructive pulmonary problems and chronic bronchitis. Causes of emphysema include chronic cigarette smoking, exposure to secondhand smoke, air pollution, and in the underdeveloped parts of the world. Symptoms of emphysema include chronic cough, chest discomfort, breathlessness, and wheezing. Treatments include medication and lifestyle changes.
Lungs Design And PurposeThe lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.

Nontuberculous Mycobacterial Lung Disease
Nontuberculous mycobacteria (NTM), most commonly, M. avium complex or MAC, is a mycobacteria that causes lung infections and disease. Nontuberculous mycobacteria are commonly found in soil, air, and water. Examples of how NTM lung infection are transmitted include swimming, using a hot tub (NTM bacteria are aerosolized), or playing with or handling soil.
The most common symptoms of NTM lung infection are chronic, dry cough, and shortness of breath. Sometimes the cough may have mucous or blood. Other symptoms of NTM lung disease include fatigue, chest pain, malaise, and weakness. As NTM lung disease progresses, fevers, night sweats, and appetite loss may occur. Treatment guidelines for NTM lung disease depend upon the type and extent of the infection, and the person's health.
