What is chronic obstructive pulmonary disease (COPD)?

Chronic obstructive pulmonary disease (COPD) is a shortened name for some of the long-term lung and airway scarring that clog (block) your airways and make it hard to breathe. Either emphysema or chronic bronchitis means that you have COPD.
Remodeling of your lungs and airways in COPD includes:
 

• Decreased flexibility of your air sacs and airways (alveoli).
• Inflammation, fibrosis (scarring) and narrowing of your airways.
• Thick mucus in your airways.
• Destruction of walls between your alveoli.
• They enlarge and block leakage of air.
   

COPD patients normally have exacerbations, or worsening symptoms, of smelly shortness of breath, stickier mucus that blocks airways, wheeze and cough. You might have to be hospitalized during severe exacerbations. COPD slowly worsens over decades. Flare-ups get worse and become more common. This usually happens over years or decades, but some people decline more rapidly.

Types of chronic obstructive pulmonary disease

COPD comprises both emphysema and chronic bronchitis. The majority of patients with COPD have both.
  

• Emphysema is when your alveoli become inflamed and damaged. The most common symptom is shortness of breath (dyspnea).
• Chronic bronchitis is inflaming your large airways. It makes your airways smaller and a lot of mucus is produced. The most common symptom is cough.

Symptoms of COPD 

COPD symptoms don't typically happen until a lot of lung damage is done. COPD symptoms will gradually get worse, especially if exposure to smoke or other irritants goes on.

Some of the symptoms of COPD include:
 

• Having trouble catching your breath, especially with exertion.
• Wheezing or whistling sound while breathing.
• Long-standing cough that may produce great amounts of mucus.
• The mucus is likely to be clear, white, yellow or greenish.
• Tightness or heaviness in the chest.
• Fatigue or severe tiredness.
• Frequent infections of the lung.
• Spontaneous loss of weight. This is achievable as the disease progresses.
• Swelling of ankles, feet or legs.
   

Patients with COPD also usually experience intervals of more than normal day-to-day variation in symptoms. This greater fluctuation in symptoms is referred to as an exacerbation (eg-zas-er-bay-shun). Exacerbations can last from a few days to several weeks. Precipitants of an exacerbation are odors, cold air, dirty air, cold or infection.
 

Symptoms can be:

• Needing to work harder to breathe or breathe with effort.
• Tightness in the chest.
• Cough that is increased.
• Excess mucus or color or consistency of mucus.
• Fever.

What Causes COPD and How It Affects Your Lungs?

COPD is not sudden work—it is built up over many years with the exposure to the harmful irritants that kill lung tissue. Having a handle on the causes and how your lungs react will help you make breathing protective steps and get treated early if you do need to see a doctor.
 

Main Causes of COPD

The most prevalent etiology of COPD in most industrialized nations is chronic cigarette smoking. But cigarette smoking is not the sole offender—there are other environmental and occupational exposures that contribute to the causation of this chronic pulmonary disease as well.
 

These are the prime offenders of COPD:

• Tobacco Smoke: This is by far the most prevalent cause. Smokers—particularly over decades—have far greater probabilities of getting COPD. Yet, not all smokers will get detectable symptoms, but nonetheless, lung damage can quietly happen over time.
• Indoor Air Pollution: Most people in developing nations are exposed to biomass fuel smoke from burning wood, coal, or animal dung for heating and cooking. These vapors bring about much irritation and with time destroy the lungs in poorly ventilated homes.
• Occupational Exposure: In addition, exposure to dusty environments, chemical fumes, vapors, or smoke (e.g., construction site, factory, or mines) leads to chronic lung inflammation and raises COPD risk—particularly without safety equipment.
• Secondhand Smoke & Other Irritants: Secondhand smoke, pipe smoke, cigar smoke, or tainted air exposure on a daily basis also leads to lung injury and raises other risk factors.
• Genetic Causes – Alpha-1 Antitrypsin (AAT) Deficiency: Approximately 1% of COPD is caused by a genetic condition known as alpha-1 antitrypsin deficiency. Individuals who carry this condition are missing a protective protein, which protects the lungs from harm. Therefore, they can develop COPD or emphysema at an early age-even if they have never smoked. In certain instances, the condition also causes liver damage.
• Puzzlingly, not all smokers develop COPD: That indicates that genetics and other personal characteristics—such as exposure to pollution in early life or childhood infections of the respiratory system—may affect who develops the disease. But even those with no symptoms at all can have compromised lung function and hidden damage from years of smoking.
   

That's why regular lung exams are advised—particularly in current or former smokers or a family history of COPD.

Who's at Risk for COPD?

There are a number of things that can put you at risk for developing COPD. Some are lifestyle-related, some are environmental, and some are even genetic.
 

Top Risk Factors Include:

• Tobacco Smoke: The risk factor for COPD is long-term cigarette smoking. The more you smoke—and the longer you've been smoking—the higher your risk. Pipe, cigar, and marijuana smoking can also be a factor, as can repeated exposure to secondhand smoke.
• Asthma: Those with asthma already have inflamed airways. When they smoke or are exposed to other lung irritants, they are more susceptible to developing COPD.
• Occupational Exposure: Certain jobs that involve long-term exposure to dust, chemical fumes, smoke, or vapors (like mining, construction, or factory work) can predispose to lung inflammation and damage.
• Indoor Air Pollution: In certain regions of the globe, heating or cooking homes by burning coal, wood, or other fuels—particularly in poorly ventilated homes—is harmful to the lungs in the long term.
• Genetics: A genetically rare disorder called alpha-1 antitrypsin deficiency (AATD) can lead to COPD, even without smoking. Other inherited characteristics can lead to COPD in certain smokers.

Complications of COPD

As your COPD progresses, it doesn't stay contained in your lungs. It spreads to the other areas of your overall well-being too.
 

Some of the most frequent complications are:

• Recurrent Respiratory Infections: Individuals with COPD are at increased risk of developing colds, flu, and pneumonia. They can become a lot more difficult to breathe and can accelerate lung deterioration.
• Heart Disease: COPD increases the risk of heart problems, including heart attacks. The exact reason isn't fully understood but may be linked to lower oxygen levels and inflammation.
• Lung Cancer: Having COPD increases your chances of developing lung cancer—especially if you’re a smoker.
• Pulmonary Hypertension: This is high blood pressure in the arteries of your lungs. It can develop as a result of severe COPD and puts strain on your heart.
• Anxiety and Depression: Living with a chronic disease and struggling to breathe can affect your mental health, leading to increased stress, anxiety, or depression.

How Is COPD Diagnosed?

Early diagnosis can make a big difference in managing COPD effectively. If you’re experiencing symptoms like shortness of breath, a lingering cough, or wheezing, your healthcare provider will conduct a thorough evaluation.
 

Your doctor may ask questions like:

• Did you ever smoke or have any secondhand smoking?
• Do you spend time or work in dusty, fume-containing, or dirty places?
• Has COPD or liver disease occurred in you or any close blood relatives?
• Are you ever short of breath even when standing or sitting?
• Are you having trouble coughing up or spitting up mucus on a frequent basis?
   

Tests Used to Diagnose COPD

Your doctor makes a diagnosis of COPD with the help of some or all of the following tests:
 

• Pulmonary Function Tests (Spirometry): Tests how much air you can blow out in one second (FEV1) and how well your lungs are functioning in general.
• Pulse Oximetry: A nonpainful test with a clip on your finger to determine the oxygen level in your blood.
• Imaging Tests: Chest X-ray or CT scans allow visualizing changes in your lungs as a result of COPD.
• Arterial Blood Gas Test: Blood test that calculates the amount of oxygen and carbon dioxide and checks how efficiently your lungs are exchanging the gases.
• Exercise Testing: Helps to check if your level of oxygen falls while exercising.
• Electrocardiogram (ECG/EKG): Checks your heart rhythm and function to rule out causes of breathlessness due to the heart.
• Alpha-1 Antitrypsin Test: A test to see whether you have the genetic form of COPD secondary to AAT deficiency.
• Genetic Testing: In case there is a suspicion regarding inherited diseases, your physician might prescribe a genetic workup.

How Is COPD Treated?

Treatment of COPD focuses on the alleviation of symptoms, prevention of complications, and the improvement of the overall quality of life. Your physician will adapt your treatment to the severity of your symptoms, lung function, and lifestyle.
 

1. Quit Smoking

The single most significant thing you can do—if you are a smoker—is to quit. Smoking is responsible for the majority of COPD cases, and quitting at any point during the disease can reduce its progression and enhance your lung function. Your physician might suggest:

• Behavior therapy or counseling
• Nicotine replacement (patches, gum)
• Prescription medications
• Stop-smoking programs or groups
   

2. Inhaled Medications

The majority of individuals with COPD utilize inhalers to assist with opening up airways and lowering inflammation. Among the most common inhaled medicines are:
 

• Bronchodilators: Cause muscles around airways to relax, allowing for easier breathing.
• Inhaled corticosteroids: Lower airway inflammation and prevent flare-ups.
• Combination inhalers: Combine bronchodilators and steroids to improve symptom management.
   

3. Nebulizer Treatments

For people who are having trouble with inhalers or require more medicine, your physician can prescribe liquids to be taken with a nebulizer—a device that converts the medication into a mist you inhale.
 

4. Oxygen Therapy

If your oxygen level is too low, your physician can add supplemental oxygen. You may need it with exercise, at night, or all the time, depending on your condition.
 

5. Pulmonary Rehabilitation

This is a structured program that includes:
 

• Supervised exercise
• Breathing techniques
• Nutritional guidance
• COPD education and emotional support
• Pulmonary rehab can help improve your lung strength, endurance, and overall wellbeing.
   

6. Medications for Flare-Ups

• During COPD exacerbations (flare-ups), your doctor might recommend:
• Oral corticosteroids to reduce inflammation
• Antibiotics if there’s a bacterial infection
• BiPAP (bilevel positive airway pressure) machines to assist your breathing during severe episodes
   

7. Advanced Treatments

• For people with severe COPD, other options might include:
• Lung volume reduction (LVR) surgery or valve surgery to remove or close diseased parts of the lung and enhance breathing.
• Clinical trials, which are experiments with new treatments that might be better for some patients.

For those seeking expert care, the best hospital for COPD treatment, offers personalized treatment plans and advanced pulmonary care to help patients breathe easier and live healthier lives.

Preventing COPD and Its Complications

The best prevention against developing COPD is avoiding smoking and the avoidance of lung irritants. Even if you have COPD, there is a lot you can do to prevent it from getting worse and to prevent complications.
 

Here's How to Protect Your Lungs:

• Quit Smoking: Quitting smoking is the most effective action you can take to slow COPD and lower your risk of lung cancer and heart disease.
• Stay Away from Secondhand Smoke and Pollutants: Avoid being around smoke and reduce exposure to dust, fumes, and air pollution. If you have a job that exposes you to chemical vapors or dust, talk to your employer about using proper protective equipment.
   

Flu shot annually

• Pneumococcal vaccine to stop certain pneumonias
• COVID-19 vaccine and boosters, as advised
• RSV vaccine if you are eligible

Take Care of Your Mental Health: Having a chronic condition is often emotionally demanding. If you feel sad, worried, or overwhelmed, talk with your healthcare provider or mental health specialist. Support groups can help you feel less isolated.
