Chronic Obstructive Pulmonary Disease (COPD): 3.5 million deaths in 2021.

Do you smoke or spend long hours in dusty, smoky, or chemical-filled environments? If yes, you may be at high risk of developing Chronic Obstructive Pulmonary Disease (COPD).
Does COPD only happen to people who smoke or work in dusty, smoky, or chemical-filled environments? Let’s understand the reality.
The answer is “NO.” COPD is more common in smokers and people exposed to dust, smoke, or chemicals, but it can also affect others due to genetics, infections, or long-term lung irritation.

Chronic Obstructive Pulmonary Disease (COPD) is a lung disease that develops slowly over time. In the beginning, we may not even notice it, but as time passes, it gets much worse. In COPD, our lungs become damaged, making it hard to breathe. The airways become narrow, and they fill with too much mucus, which further blocks airflow. The tiny air sacs in the lungs also start to get destroyed.
The main causes, as mentioned earlier, are smoking, exposure to dust and smoke, and working in chemical environments. Some studies show that it caused approximately 3.5 million deaths in 2021; approximately 5% of all global deaths are caused by chronic obstructive pulmonary disease.

Causes of Chronic Obstructive Pulmonary Disease (COPD)

Smoking

Did you know that smoking is responsible for nearly 90% of COPD cases? Every puff slowly damages your lungs, bringing you closer to this life-threatening disease.

Bad air quality or pollution

Industrial smoke and poor air quality are hidden factors that can trigger chronic obstructive pulmonary disease (COPD).

Workplace Exposure

Working for years in mines, construction sites or chemical factories can damage your lungs and lead to Chronic Obstructive Pulmonary Disease (COPD)

Genetic Mutation

In some people (about 1%), chronic obstructive pulmonary disease (COPD) is caused by a genetic problem. Their bodies don’t make enough of a protective protein called alpha-1-antitrypsin (AAT), which normally helps protect the lungs from damage.

Type of Chronic Obstructive Pulmonary Disease (COPD)

Chronic bronchitis

In chronic bronchitis our lungs become narrow due to the swelling. Too much mucus starts forming in our airways, due to which we start coughing too much and for a long time and make it difficult to breathe.

Emphysema bronchitis

Emphysema occurs when the walls of the air sacs inside your lungs become damaged. This causes air to become trapped inside the lungs, which can make you feel short of breath (shortness of breath).

Common Symptoms of COPD

• A long-lasting cough.
• Cough in which mucus comes out.
• Shortness of breath.
• Blocked chest.
• Difficulty taking deep breaths.

How COPD is Diagnosed

Spirometry Test

This test measures the amount of air you can blow out of your lungs.

Physical examination

The doctor will examine you physically and ask you about your symptoms and medical history. They will place a stethoscope on your chest and back to listen to your breathing.

Treatment Options for Chronic Obstructive Pulmonary Disease (COPD)

COPD is not curable, but there are treatments that can help to reduce symptoms.

Lifestyle Changes to Protect Your Lungs

Stay Active & Eat Healthy: 🏃‍♂️ It is necessary to exercise regularly and eat a balanced diet that keeps your lungs strong. (The Ultimate COPD Diet Cookbook: An Essential Step-by-Step Dietary Guide With Delectable, Nutritious, and Easy-To-Follow Recipes To Managing And Living Better With COPD)

Quit Smoking: 🚭 The most powerful step to slow down COPD is to protect your lungs, and it’s necessary to quit smoking to protect your lungs.

Breathe Cleaner Air: 🌬️ If you live in a polluted city, invest in an air purifier for safer breathing or try to move forward to a clean one.

Workplace Safety: 🏭 Jobs in mining, construction, or chemical areas expose you to harmful gases—consider protective measures or even a job change for your health if required.

Medicine

The doctor can prescribe you many medicines as per your examination. Oral antibiotics, such as bronchodilators, steroids, and anticholinergics, to control inflammation and relax the muscles around your airways.

Oxygen Therapy

Oxygen therapy may be suggested for people who have advanced COPD and have low oxygen levels in their blood.

Prevention Tips for COPD

1. Avoid Smoking
2. Limit Exposure to Pollutants
3. Regular Checkups
4. Avoid things that irritate your lungs
5. Try Yoga

Recent Research Updates on COPD (2024–2025)

👉 First FDA-Approved Biologic for COPD—Dupilumab

In April 2024, the U.S. FDA approved dupilumab (Dupixent) as the first biological treatment for COPD in patients with high eosinophil levels. In clinical trials, when used with inhalers, it reduced COPD flare-ups by about 30–34% and improved lung function.

👉 New PDE3/4 Inhibitor – Ensifentrine (Ohtuvayre)

In June 2024, the FDA approved a new maintenance bronchodilator for COPD. It works by relaxing the airway muscles and reducing inflammation, helping patients breathe better. This treatment is also included in the GOLD 2025 COPD guidelines.

👉 AI-Based Rapid COPD Diagnosis

A UK company, N-Tidal Diagnosis, has developed an AI-based test that can detect COPD in under 5 minutes by studying a patient’s breath. The NHS started using this technology in April 2025.

👉 Carbon Buildup in COPD Lungs

A study found that smokers with COPD had three times more carbon in their lungs compared to healthy non-smokers. This extra buildup can increase inflammation and make lung damage worse.

• Reference: Washington Post – COPD Lung Carbon Study

👉 AI Predictive Model for Exacerbations – AI-PFT-Clin

Deep learning (AI) models that use lung test images and patient data can predict severe COPD flare-ups more accurately than older methods.

Final Thoughts

COPD is a life-threatening disease, as I earlier said, with approximately 3.5 million deaths in 2021 reported by COPD, and unfortunately, there is no permanent cure. But if it is detected early, it can be managed well, and you can live a normal life. The best thing you can do is quit smoking—this is extremely important. You also need to shift to a healthy diet to keep your lungs strong and safe.
💡 Your lungs, your life—take care before it’s too late. 💡
