Chronic obstructive pulmonary disease (COPD) is a long-term, progressive lung disease that makes it hard to breathe. If you’re a smoker with COPD, the risk of complications from respiratory infections like COVID-19 is significantly higher. The ongoing pandemic has amplified concerns about vulnerable groups, and individuals with COPD fall squarely into this category. This article will explore why smokers with COPD are at increased risk for severe COVID-19 outcomes and what steps can be taken to protect themselves.
What is COPD?
COPD, or chronic obstructive pulmonary disease, is a lung condition that includes emphysema and chronic bronchitis. It affects millions of people worldwide, primarily those who smoke or have smoked in the past. COPD causes the airways in the lungs to become inflamed and narrowed, making it difficult to breathe. Over time, the damage to the lungs worsens, leading to a gradual decline in lung function.
Common symptoms of COPD include:
- Persistent cough
- Shortness of breath
- Wheezing
- Frequent respiratory infections
- Excess mucus production
COPD is a progressive disease, meaning it gets worse over time. There is no cure for COPD, but it can be managed with medications, lifestyle changes, and oxygen therapy.
How Does Smoking Impact COPD?
Smoking is the leading cause of COPD. Cigarette smoke contains harmful chemicals that irritate and damage the airways and lung tissue. Over time, this damage leads to the development of COPD in many smokers.
Here’s how smoking worsens COPD:
- Inflammation: Smoking causes chronic inflammation in the airways, which leads to swelling and obstruction.
- Mucus Production: Smoking increases mucus production, making it harder to breathe and more likely to develop infections.
- Lung Tissue Damage: Smoking damages the tiny air sacs (alveoli) in the lungs, reducing the lungs’ ability to transfer oxygen to the bloodstream.
For people who continue to smoke after being diagnosed with COPD, the disease progresses more quickly, leading to more severe symptoms and complications.
COVID-19 and Its Impact on the Lungs
COVID-19, caused by the SARS-CoV-2 virus, primarily affects the respiratory system. In many cases, the virus leads to mild to moderate respiratory symptoms, such as a cough, fever, and shortness of breath. However, in severe cases, COVID-19 can cause pneumonia, acute respiratory distress syndrome (ARDS), and long-term lung damage.

For individuals with pre-existing lung conditions like COPD, COVID-19 poses a significant threat. Their already compromised lung function makes it harder to fight off the infection and recover from respiratory complications.
Why Smokers with COPD are at Increased COVID-19 Risk
Smokers with COPD are at an increased risk of developing severe COVID-19 symptoms due to a combination of factors:
1. Weakened Immune System
Smoking weakens the immune system, making it more challenging to fight off infections like COVID-19. People who smoke have a reduced ability to clear viruses from their airways, allowing infections to take hold and cause more severe respiratory issues.
2. Increased Inflammation
Both smoking and COPD cause chronic inflammation in the lungs, which worsens when a respiratory infection like COVID-19 is present. Inflammation from the virus can exacerbate existing damage to the lungs, making it harder to breathe and recover from the infection.
3. Reduced Lung Function
COPD already reduces lung function, making it difficult to breathe. COVID-19 further compromises lung function by causing pneumonia or ARDS, making it extremely dangerous for individuals with COPD. Smokers with COPD may have such severely damaged lungs that even mild cases of COVID-19 can become life-threatening.
4. Higher Risk of Respiratory Failure
COVID-19 can lead to respiratory failure, where the lungs are unable to deliver enough oxygen to the body. For someone with COPD, whose lungs are already compromised, the risk of respiratory failure is significantly higher.
5. Higher Hospitalization and Mortality Rates
Studies have shown that smokers and individuals with COPD are more likely to be hospitalized and face severe outcomes from COVID-19. This includes higher rates of ICU admission, mechanical ventilation, and death.
What the Research Says
Various studies have highlighted the increased risk smokers and people with COPD face when infected with COVID-19:
- A study published in the European Respiratory Journal found that individuals with COPD were at greater risk for severe outcomes from COVID-19, including the need for mechanical ventilation and a higher risk of death.
- Research published in the Journal of Medical Virology found that smokers were 1.91 times more likely to develop severe symptoms of COVID-19 compared to non-smokers.
- Data from the Centers for Disease Control and Prevention (CDC) also indicates that individuals with chronic lung conditions like COPD are more likely to experience severe complications from COVID-19, including hospitalization and death.
How to Reduce the Risk for Smokers with COPD
Although smokers with COPD are at higher risk for severe COVID-19 outcomes, there are steps they can take to protect themselves and manage their condition during the pandemic. Dr. Sheetu Singh recommends personalized strategies to help individuals with COPD reduce risks and maintain respiratory health during these challenging times.
1. Quit Smoking
Quitting smoking is the most important step anyone with COPD can take to improve their lung function and overall health. While quitting smoking won’t reverse COPD, it can slow the progression of the disease and reduce the risk of complications from COVID-19 and other respiratory infections. There are many resources available to help smokers quit, including nicotine replacement therapy, prescription medications, and counseling.
2. Follow COVID-19 Safety Guidelines
Individuals with COPD should be extra cautious during the COVID-19 pandemic to avoid exposure to the virus. This includes following guidelines such as:
- Wearing a mask: Masks can help prevent the spread of COVID-19 and protect individuals with COPD from exposure to the virus.
- Social distancing: Avoid large gatherings and keep a safe distance from others, especially in crowded or poorly ventilated areas.
- Frequent handwashing: Wash your hands regularly with soap and water for at least 20 seconds to reduce the risk of infection.
3. Stay on Top of COPD Treatment
Managing COPD effectively is crucial to reducing the risk of severe complications from COVID-19. This includes:
- Taking medications as prescribed: Continue using long-term control medications, such as inhalers or nebulizers, to keep COPD symptoms under control.
- Monitor symptoms: Keep track of any changes in breathing or lung function and contact your healthcare provider if symptoms worsen.
- Stay active: Regular physical activity can help maintain lung function and overall health, even if it’s just light walking or stretching.
4. Get Vaccinated
COVID-19 vaccines have been shown to be highly effective at reducing the risk of severe illness, hospitalization, and death from COVID-19. People with COPD should make sure they are fully vaccinated and receive any recommended booster shots. Additionally, getting the flu vaccine can help prevent complications from respiratory infections. Dr. Virendra Singh emphasizes the importance of these vaccines for individuals with COPD to protect their respiratory health and reduce the risk of severe complications.
5. Have an Action Plan
If you have COPD, work with your healthcare provider to create an action plan for managing your condition during the pandemic. This plan should include:
- Steps to take if you develop COVID-19 symptoms.
- A list of medications you take regularly and any changes needed during an illness.
- When to seek medical help or go to the hospital if symptoms worsen.
When to Seek Emergency Care
If you have COPD and develop COVID-19 symptoms, it’s essential to seek medical care early. Symptoms of COVID-19 can escalate quickly in people with chronic lung conditions. Seek emergency care if you experience:
- Difficulty breathing or shortness of breath.
- Persistent chest pain or pressure.
- Confusion or difficulty staying awake.
- Bluish lips or face.
Conclusion
Smokers with COPD are at a significantly higher risk of severe complications from COVID-19 due to their reduced lung function and compromised immune system. However, by quitting smoking, managing COPD effectively, and following COVID-19 safety protocols, individuals can reduce their risk of severe illness. Vaccination is also crucial in protecting against COVID-19. If you or a loved one has COPD, it’s important to take extra precautions during this pandemic and work with healthcare providers to ensure you stay as healthy and safe as possible.
