Can you survive with one lung? Yes, you can survive with one lung. One lung is enough to lead a normal life. The remaining lung compensates and has to work harder. That helps stabilize oxygen levels.
Some believe that since you lose a lung, you can’t be active. This isn’t true. You may get more tired during exercise, but many day-to-day tasks are still attainable. Another myth is that the remaining lung tends to fail. It can live healthily with the right care.
These points may help reduce fears about life with one lung. It is easier to make informed decisions when you are aware of the facts.
So let’s talk about it in detail.
Why Would Someone Need a Lung Removed?
Doctors recommend having a lung removed for various medical reasons, but they advise it only when they consider it unavoidable. Reasons that lung removal surgery (pneumonectomy) may be recommended:
Lung Cancer
The removal of a lung is usually performed for Lung cancer. If cancer spreads in one lung, but not the other, doctors may cut out the affected lung, to prevent it from spreading.
Severe Lung Diseases
Some lung diseases can damage one lung so severely that it has become nonfunctional. These include:
- Chronic Obstructive Pulmonary Disease (COPD) – A progressive disease that causes continual BLOCKAGE of airflow.
- Pulmonary Fibrosis – A condition that scars lung tissue, making breathing difficult.
- Bronchiectasis — A condition in which airways become enlarged and mucus collects in the lungs, creating an environment for infection.
Infections That Do Not Heal
Two lung infections unresponsive to antibiotics may need forever lung removal. Some examples include:
- Tuberculosis (TB) – A condition caused by bacteria that harm lung tissue.
- Lung Abscess – A pus-filled infection that is resistant to treatment.
Traumatic Lung Injury
A big trauma, such as a car crash or gunshot, can severely affect one lung. If they can’t fix it, doctors may have to take it out.
Birth Defects
Others are born with lung defects that make breathing difficult. Doctors in rare instances remove an affected lung so that a person can breathe in comfort.
Lung removal is never done on the fly. They first see if the other lung is healthy enough for the job and whether the patient is strong enough for the surgery.
What to Expect From Lung Removal Surgery
Pneumonectomy, or the surgical removal of a lung, is a complex operation. It takes elaborate planning, expert surgeons, and a lengthy recovery.
Before the Procedure
Surgeons do not leave anything to chance. They do all the tests to make sure you can live with one lung. Some of these include:
-
Lung Tests
-
Scans (X-ray, CT, MRI, PET)
-
Heart tests (ECG, Echo, Stress Test)
-
Blood Work
The Operation Itself
Lung removal is performed in a hospital with general anesthesia. Surgeons do their work while the patient is completely unconscious.
- Incision – The surgeon makes a cut on the side of the chest to reach the lung.
- Separating the Lung – The surgeon carefully detaches the lung from the blood vessels and airway.
- Removing the Lung – The entire lung is taken out.
- Closing the Chest – The surgeon seals the area and may place a chest tube to drain fluid and air.
- Recovery Room – The patient is moved to a recovery area and monitored closely.
The surgery takes 2 to 6 hours, depending on the complexity.
Types of Lung Removal Surgeries
There are two main types of lung removal procedures:
- Simple Pneumonectomy – Only one lung is removed.
- Extrapleural Pneumonectomy (EPP) – The lung, part of the diaphragm, the lung lining, and sometimes part of the heart lining are removed (mainly for mesothelioma, a rare cancer).
After the Surgery
Patients usually stay in the hospital for a week or longer. They receive oxygen therapy, pain management, and physical therapy to help their body adjust.
Can You Live a Normal Life with One Lung?
Yes, many people live normal and active lives with just one lung. While there are some challenges, the body adapts over time.
How Does the Body Adjust?
The remaining lung expands to fill up with more air when one is removed. As it continues to heal, it gets tighter and stronger. The diaphragm and rib muscles also pitch in, working harder to prop up breathing.
To fast up that adjustment, doctors recommend breathing exercise. Pulmonary rehabilitation programs give patients breathing exercises and work to strengthen the muscles around the lungs to use oxygen more effectively.
Exercise with One Lung
Most people with one lung can walk, work, and even exercise. But strenuous activities such as long-distance running or high-altitude climbing might be more difficult.
-
Low-intensity exercise (walking, stretching, and yoga)
-
Moderate exercise (cycling, swimming)
-
Strenuous exercise (long-distance running, heavy weightlifting)
Various athletes, from swimmers to runners, have done quite well with one lung. It requires patience, training, and the right medical guidance.
Breathing Differences
With one lung, breathing feels different, especially at first. You may notice:
-
Getting tired faster than before.
-
Feeling short of breath with intense activity.
-
Needing more time to recover after exertion.
Using breathing techniques like pursed-lip breathing and diaphragmatic breathing can help.
Daily Life Adjustments
Cooking, working, and socializing most daily tasks continue unchanged. But a few changes may be useful if you:
-
Avoiding smoke and pollution
-
Consume a Healthy Diet (Foods with Protein And Antioxidants Aid Lung Wellbeing)
-
Regular check-ups
Many people with one lung live long, fulfilling lives. With appropriate care, they can perform nearly all activities they did prior to surgery.
Common Side Effects & Challenges of Living on One Lung
It is possible to live with one lung, but it does have certain side effects and challenges. The body adapts over time, but some of the changes are permanent. A good understanding of these challenges can lead to better management of them.
1. Shortness of Breath
One of the most common side effects is shortness of breath (dyspnea). Since one lung is missing, the remaining lung has to work harder to bring in enough oxygen.
When is shortness of breath most noticeable?
- During physical activity – Walking uphill, climbing stairs, or lifting heavy objects may feel more tiring.
- In high altitudes – Places with thin air make breathing harder.
- During illness – Colds, flu, or infections can make it more difficult to breathe.
How to manage it:
- Practice breathing exercises like diaphragmatic breathing.
- Use pursed-lip breathing to slow down and control breathing.
- Stay active but pace yourself.
2. Reduced Exercise Capacity
Many people with one lung can still work, travel, and enjoy hobbies, but their endurance may be lower.
Challenges:
- Fatigue sets in faster during long activities.
- Aerobic exercises like running or swimming may be harder.
- Recovery time after exertion is longer.
How to improve stamina:
- Start with low-impact exercises (walking, stretching, light yoga).
- Increase intensity gradually based on comfort.
- Follow a pulmonary rehab program if recommended by doctors.
3. Higher Risk of Infections
With only one lung, infections like pneumonia can be more serious. The lung has to work harder, and mucus clearance is slower.
Prevention tips:
- Get flu and pneumonia vaccines to reduce infection risk.
- Stay away from smoke and pollution – Avoid smoking, secondhand smoke, and dusty environments.
- Wash hands frequently to prevent colds and respiratory infections.
4. Changes in Coughing & Mucus Production
Coughing helps clear mucus from the lungs. After lung removal, the body adjusts, but mucus clearance may be slower. Some people experience:
- More frequent coughing to clear the airway.
- A dry or weak cough that doesn’t clear mucus well.
Managing mucus buildup:
- Stay hydrated to thin mucus.
- Use humidifiers to keep airways moist.
- Practice controlled coughing techniques to clear airways effectively.
5. Mental & Emotional Adjustments
Losing a lung can feel overwhelming at first. Some people experience:
- Anxiety about breathing difficulties
- Frustration with activity limits
- Fear of future health problems
How to cope:
- Talk to a doctor or therapist if anxiety affects daily life.
- Join support groups for people with lung conditions.
- Focus on what you CAN do, not what you can’t.
6. Sleep Challenges
Some people with one lung experience:
- Breathlessness while lying down
- Sleep disturbances due to discomfort
Tips for better sleep:
- Use extra pillows to elevate the upper body.
- Avoid large meals before bed to prevent pressure on the diaphragm.
- Try relaxation techniques like deep breathing before sleep.
How to Improve Quality of Life with One Lung
Losing a lung can change how the body functions, but it doesn’t mean life has to be difficult. Many people adjust well and live active lives. With the right lifestyle, breathing techniques, and medical care, you can improve your quality of life and keep your remaining lung healthy.
1. Protect Your Remaining Lung
With only one lung, it’s crucial to keep it healthy. Any damage or illness can make breathing harder.
How to protect lung health:
- Avoid smoking & secondhand smoke – Smoking damages lung tissue and increases the risk of infections.
- Limit exposure to pollution – Use air purifiers and avoid dust, strong chemicals, or fumes.
- Get flu & pneumonia vaccines – These prevent serious respiratory infections.
- Practice good hygiene – Wash hands often to avoid colds and lung infections.
2. Stay Physically Active
Exercise helps keep the lungs strong and improves stamina. While intense activities may be harder, light to moderate exercise can be beneficial.
Best exercises for people with one lung:
- Walking – Start slow and increase your distance over time.
- Swimming – Water supports the body and makes breathing exercises easier.
- Yoga & stretching – These improve lung expansion and flexibility.
- Strength training – Light weights help build endurance without overstraining the lungs.
Tips for safe exercise:
- Warm up before workouts.
- Stop and rest if you feel breathless.
- Avoid extreme weather conditions (too hot, too cold, or high altitude).
3. Master Breathing Techniques
Breathing exercises help increase lung efficiency and reduce shortness of breath.
Effective techniques include:
- Diaphragmatic breathing – Breathe deeply using your belly instead of shallow chest breathing.
- Pursed-lip breathing – Breathe in through the nose and slowly breathe out through pursed lips.
- Controlled coughing – Helps clear mucus without straining the lungs.
Practicing these techniques daily improves oxygen intake and lung function.
4. Maintain a Healthy Diet
What you eat affects lung function. A nutrient-rich diet can reduce inflammation, improve breathing, and keep energy levels stable.
Best foods for lung health:
- Fruits & vegetables – Rich in antioxidants that protect lung tissue.
- Lean proteins – Chicken, fish, eggs, and beans help muscle recovery.
- Healthy fats – Nuts, seeds, and olive oil reduce inflammation.
- Whole grains – Oatmeal, brown rice, and quinoa provide long-lasting energy.
Foods to limit:
- Processed foods high in salt and sugar.
- Fried and greasy foods that can cause bloating.
- Carbonated drinks that add pressure on the diaphragm.
5. Improve Sleep Quality
People with one lung may struggle with breathlessness while lying down. A few changes can help improve sleep.
Tips for better sleep:
- Sleep with your head elevated – Use extra pillows or an adjustable bed.
- Maintain a bedtime routine – Go to bed at the same time every night.
- Avoid large meals before bed – A full stomach can press on the diaphragm.
- Use a humidifier – Moist air prevents dryness and irritation.
6. Manage Stress & Mental Health
Losing a lung can bring stress, anxiety, and frustration. Learning to cope mentally is just as important as physical health.
Ways to reduce stress:
- Practice meditation & mindfulness – Deep breathing and relaxation techniques can calm the mind.
- Stay socially active – Spend time with family, friends, or support groups.
- Seek professional help – If stress or anxiety affects daily life, talk to a counselor.
