Can lungs improve in a 55-year-old ex-smoker with COPD?

Question

Hello doctor,

I am a 55-year-old man and a former heavy smoker; for more than 25 years, I smoked almost two packs a day. I quit three years ago, and since then, I have been actively involved in an anti-smoking campaign in my community, sharing my experience to raise awareness.

Recently, I was diagnosed with moderate COPD. My spirometry results showed an FEV₁ (the amount of air you can forcefully exhale in one second) at 58 percent of the predicted value, and an FEV₁/FVC ratio of 0.62. Now, I deal with daily breathlessness, a chronic cough, and occasional wheezing, especially in the mornings.

I currently use a combination inhaler containing Formoterol and Budesonide, but I still find it difficult to walk more than 200 meters without feeling winded. My biggest worry is that even though I quit smoking, the lung damage may already be irreversible. Is there still any chance of improving my lung function, or is the focus now only on slowing the disease’s progression?

I also wonder whether it is safe for me to keep participating in outdoor awareness events, especially on days when air pollution is high. Another challenge I face is convincing younger people about the long-term risks of smoking when they feel “it will not happen to them.” On bad days, I still need supplemental oxygen, and sometimes that makes me feel hypocritical.

How can I balance being honest about my condition while still giving people hope? Please help.

Thank you for your time and guidance.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

I have gone through your spirometry results (attachments were removed to protect the patient's identity), an FEV₁ of 58 percent predicted and an FEV₁/FVC ratio of 0.62, and these point to moderate airflow limitation.

FEV₁ (forced expiratory volume in one second): How much air you can blow out forcefully in one second.
FVC (forced vital capacity): The total amount of air you can exhale after a deep breath.
FEV₁/FVC ratio: A measure that helps us see if your airways are narrowed.
Moderate airflow limitation: There is some narrowing that makes breathing harder, but with the right steps, you can still improve your daily quality of life.

Quitting smoking was truly the most powerful decision you could have made for your lungs. While it may not reverse the damage already done, it has slowed further decline and will continue to protect the lung function you have. With consistent treatment, pulmonary rehabilitation (supervised exercises, breathing training, and education), and a few lifestyle tweaks, you can feel stronger and more in control.

The inhaler you are using, Formoterol (helps open your airways) and Budesonide (reduces airway inflammation), is well suited for your current stage. Since you are still feeling breathless with short walks, we may need to review your treatment. In some cases, adding a long-acting muscarinic antagonist (LAMA) or adjusting the current plan can make a big difference.

I know your advocacy work means a lot to you. It is safe to continue outdoor awareness events most days, but during high pollution or smog alerts, I would recommend:

Limiting your time outdoors.
Wear a good-quality filter mask.
Listening to your body, if symptoms flare, rest and protect your lungs.

And please remember, needing oxygen on some days does not make you a hypocrite. It makes your story even more real. Young people may ignore statistics, but when they see someone who has walked their path and is willing to speak openly about both the challenges and the victories, it leaves a lasting mark. Your honesty is your greatest strength; it is not just a warning, it is hope that change is possible.

If you can, share your height and weight with me. I will calculate your BMI (body mass index) to see if it is contributing to your breathlessness.

You have already taken the hardest step by quitting; now it is about protecting and making the most of the lung function you still have. I am here to guide you every step of the way.

I hope this helps.

Please revert in case of further queries.

Thank you.
