Did COVID-19 affect your lungs? (COVID-19 Lung Damage) Let's talk about this in detail!

Do you remember when COVID-19 took over the world? Back then, we all held our breaths in fear. So, when this COVID-19 virus enters our bodies, it can damage our lungs in particular. For some people, it can cause severe pneumonia or respiratory distress . For others, even after they recover, they may have trouble breathing and feel tired for a while.

What is the damage to the lungs caused by COVID-19?

Simply put, COVID-19 is a disease that affects the respiratory system. When this virus enters our lungs, our body's immune system starts to fight against it. In this fight, inflammation occurs inside the lungs. If this inflammation is not controlled, it can also damage our healthy lung cells. It's like war, when fighting the enemy, sometimes our side also gets hurt.

Normally, respiratory illnesses like the flu and the common cold can affect the lungs to some extent. But when COVID-19 first started spreading, doctors noticed that it could become more severe very quickly and cause more damage to the lungs. Some data suggests that the current variant, Omicron, is more likely to affect the upper respiratory tract (nose and throat) than the previous variant. However, it can still damage the lungs and cause serious complications.

What are the symptoms of COVID-19 lung damage?

If you have COVID-19, symptoms of conditions caused by lung damage may include:

• Difficulty breathing or shortness of breath .
• Feeling unbearably tired .
• Fever .
• Blue or gray discoloration of the skin, lips, or fingernails (cyanosis) . This occurs when the blood is not getting enough oxygen .
• Rapid, labored breathing.
• Feeling pain or tightness in the chest .

However, if you have long-term lung damage after you recover from COVID-19 , you may not experience any symptoms. Or you may feel short of breath or tired easily, even with light activity. Sometimes these symptoms may gradually worsen over time.

Why does COVID-19 damage the lungs?

The main reason for this is that our immune system overreacts . Imagine, our immune cells go to the place where the virus has arrived and fight it. That's good. But, if this fight gets out of control, that is, if the immune system becomes overactive, it can also damage healthy tissues.

When the walls of the tiny air sacs in our lungs (which we call alveoli ) become damaged and weak, they begin to fill with fluid. Then air can't get in, and oxygen can't get into the blood or to the rest of the body.

This inflammation can also cause pulmonary nodules or scarring in the lungs. These can take a long time to heal and can sometimes be permanent.

This type of damage can actually happen in other respiratory diseases, but it seems more likely to be severe in COVID-19. This could be because the virus overreacts to our immune system, causing cytokine storms , for example. Or it could be because the virus uses our own immune cells to attack the lungs.

Who is at higher risk of lung damage from COVID-19?

If you have any of the following conditions, you are more likely to have severe COVID-19 and damage your lungs:

• If you are over 65 years old.
• If pregnant .
• If you are a smoker, or have smoked in the past.
• If you have had an organ transplant or stem cell transplant .
• If you haven't taken the COVID-19 vaccine.
• If you have a weak immune system - this can be caused by conditions such as cancer, certain medications, HIV infection, or primary immunodeficiency .

Also, if you have any of the following health conditions, your risk may be increased:

• Cancer.
• Long-term lung diseases or conditions that affect the lungs, for example, asthma, COPD (Chronic Obstructive Pulmonary Disease) , and cystic fibrosis .
• Conditions affecting the heart, kidneys, liver, blood, or brain.
• Congenital conditions, for example , cerebral palsy or Down syndrome .
• Diabetes (Diabetes Mellitus).
• Mental health problems.
• Obesity.
• Drug use.

What are the complications of COVID-19 lung damage?

Inflammation caused by COVID-19 and other infections can lead to complications such as:

• Pneumonia: This is an infection of the lungs. In this, the air sacs fill with fluid.
• Acute Respiratory Distress Syndrome (ARDS):This is a very serious condition. In this, many of the air sacs in your lungs fill with fluid, preventing oxygen from getting into your blood.
• Lung nodules: Nodules may remain in the lungs due to damage caused by inflammation.
• Pulmonary fibrosis: Damaged areas of the lungs can become scarred. Sometimes, this scarring can continue to grow even after you recover from the infection.
• Long COVID: Some people may continue to have symptoms for months or even years after contracting COVID-19.

How to diagnose COVID-19 lung damage?

A doctor will look for lung damage using imaging tests (e.g., X-ray, CT scan) or bronchoscopy (a thin tube with a camera inserted into the lungs to look inside). They will also use other tests to diagnose infections, such as pneumonia.

What tests are being done?

Doctors may do tests like these to check the condition of the lungs and detect infections:

• Nasal swab: A sample is taken from the inside of your nose or throat using a cotton swab to test for COVID-19 and other viruses.
• Pulse oximetry: A small device placed on your finger measures the amount of oxygen in your blood. This can give you an idea of ​​how well your lungs are working.
• Imaging: A chest X-ray or CT scan is done to take pictures of the lungs to see if there is any damage.
• Blood tests: Blood tests help check for infections and check your general health.
• Sputum test: This involves taking a sample of the mucus that comes out when you cough and checking for infection.
• Pleural fluid culture: In this test, a doctor uses a thin needle to take a small amount of the fluid around your lungs to check for infection.
• Arterial blood gas test: This test allows doctors to see how well your lungs are working.
• Bronchoscopy: A bronchoscope can be used to look at the lungs and take tissue or fluid samples to send to a laboratory for testing.

How is COVID-19 lung damage treated?

There really isn't much you can do to completely repair your lungs after they've been damaged. But, doctors can help you get the oxygen you need. If you have pneumonia or ARDS from COVID-19, your doctor may recommend the following treatments:

• Supplemental oxygen:Your lungs are working, but if you're not getting enough oxygen, you'll be given extra oxygen through a tube placed in your nose or a mask placed on your face.
• Intravenous fluids (IV fluids): Extra fluids are given through an IV to stop the body from becoming dehydrated.
• Mechanical ventilation: If you cannot breathe on your own, you will be connected to a ventilator.
• Proning: To help your lungs work more efficiently, you are turned onto your stomach for a few hours a day.
• Extracorporeal Membrane Oxygenation (ECMO): If your organs are not working properly, you may be connected to a life-saving machine that does the work of your heart and lungs.
• Fluid draining: To reduce the fluid in your lungs, a doctor may use a catheter or surgery to remove the fluid.

Doctors may also prescribe medications like these to help fight the infection:

• Antiviral medications: Medications like Remdesivir or Paxlovid™ can help fight COVID-19 infection.
• Corticosteroids: Doctors may use steroids or other anti-inflammatory medications to reduce swelling.
• Monoclonal antibodies: Monoclonal antibody treatments, such as tocilizumab, can reduce or prevent inflammation.
• Antibiotics: If you have a bacterial infection in addition to COVID-19, your doctor may prescribe antibiotics.

Lung transplants have rarely been performed in people with long-term, severe lung damage from COVID-19. Also, if lung scarring (pulmonary fibrosis) continues to worsen, there are some medications that can slow it down.

What should I expect if I have COVID-19 lung damage?

If you develop pneumonia or ARDS from COVID-19, you will need to stay in the hospital so doctors can help you breathe until your body recovers from the virus.

Scarring of the lungs can be long-lasting or permanent. In some cases, scarring caused by infection can continue to worsen over time, even after your other symptoms have gone away.

When should I see my doctor?

If you test positive for COVID-19, ask your doctor as soon as possible about taking antiviral medication. It is most effective if taken within the first five days of symptoms starting.

If you still have shortness of breath, fatigue, or other symptoms, talk to your doctor. Long COVID can help you feel better.There are also clinics.

When should I go to the Emergency Department (ETU) ?

If you have COVID-19 and have these severe symptoms, go to the emergency room immediately, or call 1990 (or your local emergency number):

• Severe shortness of breath or difficulty breathing.
• Confusion.
• Inability to stay awake.
• Blue discoloration of the skin, lips, or fingernails.

What questions should I ask my doctor?

It may be helpful to ask your doctor questions like these:

• Are there any treatment options available to me?
• Can this heal on its own?
• How should I take care of myself?

Can COVID-19 lung damage be prevented?

The best way to prevent lung damage is to avoid getting an infection. You can do the following to reduce your risk of developing severe COVID-19:

• Get vaccinated: Getting vaccinated against COVID-19 and other diseases like the flu can reduce your risk of getting sick or becoming seriously ill.
• Quitting smoking and avoiding secondhand smoke: Smoking damages your lungs, which means you're more likely to get infections that can lead to conditions like pneumonia.
• Wash your hands thoroughly with soap and water before eating, handling food, and after using the toilet. If soap is not available, use an alcohol-based hand sanitizer.
• Avoid close contact with others and sharing items .
• Manage any other health conditions you have, as they can increase your risk of severe COVID-19.

If you get sick, taking antiviral medication within the first five days of symptoms can help prevent the illness from getting worse.

Remember, inflammation is a way your immune system uses to protect you. But if it gets out of control, it can cause damage, like the lung damage caused by COVID-19. No one can say for sure who will get seriously ill and who will have long-term effects.

Finally, take-home message:

COVID-19 is not a game, my friends. It can affect our lungs in unexpected ways. So, stay as safe as possible. Get vaccinated, follow health guidelines. If you have any symptoms, don't ignore them. Seek medical advice immediately. Especially if you have difficulty breathing or chest pain, be sure to see a doctor.

If you have any questions or concerns about COVID-19 lung damage, talk to a doctor. They can explain how to reduce your risk and treat your symptoms. Let's all stay healthy!
