Exposure to things that irritate the airways for the long term is the most common cause of the chronic obstructive pulmonary disease (COPD).
Due to COPD, the airways become inflamed, damaged, and narrowed. The main cause is cigarette smoking although the condition can sometimes affect people who have never smoked. About 85 to 90 percent of all COPD cases are caused by smoking.
Other causes of COPD include long-term exposure to harmful fumes or dust. Some rare causes of COPD include a rare genetic problem that makes the lungs more vulnerable to damage (anti-trypsin deficiency).
What is COPD?
Chronic obstructive pulmonary disease (COPD) is a name for a group of lung diseases that cause breathing difficulties.
Normally, airways and air sacs in the lungs are elastic or stretchy. While breathing in, the air sacs fill with air, such as a small balloon. While breathing out, the air sacs deflate, and air goes out.
In COPD, less air flows in and out of the airways because of one or more of the following problems:
- Airways and air sacs in the lungs become less elastic (increased pulmonary resistance).
- Walls between the air sacs become destroyed.
- Airways become thick and inflamed.
- Airways become clogged due to more mucus production.
Who is at a risk of COPD?
Risk factors for the chronic obstructive pulmonary disease include:
- Smoking (biggest risk factor)
- Exposure to air pollution
- Breathing secondhand smoke
- Working with chemicals, dust, and fumes
- Alpha-1 antitrypsin deficiency (a genetic condition)
- History of childhood respiratory infection
2 types of COPD
Chronic obstructive pulmonary disease (COPD) includes two types:
- Emphysema: It is a condition that affects the air sacs and walls between them. They become damaged, lose elasticity, and stay permanently overinflated.
- Chronic bronchitis: It is a condition in which the airway lining is constantly irritated and inflamed. This causes the lining to create more mucus and clog the airways.
Most people with COPD have both emphysema and chronic bronchitis, but the severity of each type can be different for different people.
What are the symptoms of COPD?
People with chronic obstructive pulmonary disease (COPD) might have no symptoms or only mild symptoms at first. As the disease develops over time, symptoms usually become more severe.
- Frequent cough that produces a lot of mucus
- Wheezing and whistling sound while breathing
- Shortness of breath, especially with physical activity
- Chest tightness
- Cough that doesn't go away
- Frequent colds or flu
- Blue fingernails
- Low energy
In severe cases, COPD can cause weight loss without trying, weakness in the lower muscles, and swelling in the ankles, feet, or legs.
How is COPD diagnosed?
Various tools are used in clinics to make a diagnosis, such as:
- Medical history that includes asking about symptoms and smoking or childhood asthma history
- Family history of chronic obstructive pulmonary disease (COPD) and asthma
- History of occupational exposure to chemicals and irritants
- Multiple tests including lung function tests such as spirometry, a chest X-ray or computed tomography scan, and blood tests
The diagnosis of COPD depends mainly on signs and symptoms, medical and family histories, and test results.
What are the treatment options available for COPD?
Currently, there is no cure for chronic obstructive pulmonary disease. However, treatments can help slow the progress of the disease, control symptoms and improve the ability to stay active. There are treatments available to prevent or treat complications of the disease.
Treatment options include:
- Lifestyle changes such as quitting smoking and avoiding secondhand smoke and places
- Inhalers such as bronchodilators and tablets to help make breathing easier
- Pulmonary rehabilitation (a program that helps improve the well-being of people who have chronic breathing problems)
- Exercise program
- Disease management training
- Nutritional counseling
- Psychological counseling
- Surgery or a lung transplant for people who have severe symptoms that have not gotten better with medicines

Chronic Bronchitis
Chronic bronchitis is a cough that occurs daily with production of sputum that lasts for at least 3 months, 2 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 includes GOLD guidelines, smoking cessation, medications, and surgery. The life expectancy of a person with COPD depends on the stage of the disease.
COPD Quiz
COPD 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 vs. Asthma (Differences and Similarities)
COPD (chronic obstructive pulmonary disease) and asthma both have common symptoms like coughing, wheezing, shortness of breath, and a tight feeling in the chest. COPD is caused by tobacco smoking, while asthma is caused by your inherited genetic makeup and their interactions with the environment. Risk factors for asthma are obesity, exposure to cigarette smoke (even secondhand smoke), and personal history of hay fever. There is no cure for either disease, but symptoms can be managed with medication. A person with asthma has a better prognosis and life expectancy than someone with COPD.
COPD vs. Emphysema
COPD (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
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.

How Is a Pulmonary Angiography Done?
A pulmonary angiography detects problems in the blood flow of the pulmonary vessels. The results of the procedure are shown as a moving X-ray known as a pulmonary angiogram. Doctors need to insert a catheter into your arm or groin and thread it through your veins to your heart as part of the procedure.
How Is a Pulmonary Function Test Performed?
Pulmonary function test or lung function test is a group of tests that check the workings of the lungs. They are noninvasive test which can determine the functional status of the lung cells and how well the lungs are working.

What Are Lung Segmentectomy and Limited Pulmonary Resection?
A lung segmentectomy is a procedure to remove the diseased lung without removing excess normal lung. Lung segmentectomy and limited pulmonary resection are performed due to bonchiectasis, early-stage lung cancer, lung nodules, tuberculosis, and suppurative lesions. Complications include air leakage, bleeding, residual airspace, infection of the pleural space, respiratory failure, and cardiac complications.

What Is the Life Expectancy of Someone With COPD?
Chronic obstructive pulmonary disease (COPD) is a group of diseases with the chief symptom of breathlessness and cough. COPD is a slowly progressive disease. Depending on the disease severity, the five-year life expectancy for people with chronic obstructive pulmonary disease (COPD) ranges from 40%-70%. That means 40-70 out of 100 people will be alive after five years of diagnosis of COPD.
