Are you a vaper? Then be aware of this 'Popcorn Lung'!

Do you often have a cough? Do you get a cough when you are a little tired? You may think that this is normal. However, sometimes these symptoms can be a sign of a serious health problem that we do not think about. Today we are going to talk about a lung condition that is rarely heard of, but can be very dangerous. That is 'Popcorn Lung' , or in medical terms 'Bronchiolitis Obliterans' .

What is 'Popcorn Lung'? Let's understand it simply!

'Popcorn lung' is a condition that affects the very small airways in our lungs, specifically the 'bronchioles' . Think of it like the branches of a tree. The main airway splits into two, which then split into smaller branches, and at the end are very fine channels called 'bronchioles'.

When this disease occurs, these tiny airways become inflamed , meaning they become swollen and red. Then these airways become damaged and scarred. Just like when we get a wound on our skin, a scar forms. What happens when this happens? The movement of air through those tiny airways becomes obstructed, just like when dirt gets stuck in a water pipe, it becomes difficult for the water to flow. This is also called 'Obliterative Bronchiolitis' .

Why is this called 'popcorn lung'?

This name sounds a bit strange, doesn't it? It got its name 'popcorn lung' for a very special reason. Years ago, a group of workers who worked in a microwave popcorn factory were diagnosed with this disease. The cause was that they were constantly inhaling a chemical called 'diacetyl' , which was used to add butter flavor to popcorn. That's where the name 'popcorn lung' became popular.

However, this chemical called 'diacetyl' was used not only in popcorn, but also in many other industries that use artificial sweeteners. Also, there have been reports of people who worked in coffee grinding facilities developing this disease.

The most important thing is that the liquids in electronic cigarettes, or 'e-cigarettes' or 'vapes', which are used by many young people today, may also contain this chemical called 'diacetyl'. This is a very dangerous situation.

Who is at higher risk of developing 'popcorn lung'?

Although anyone can develop this disease, some people are at higher risk of developing it. They are:

• People exposed to toxic chemicals: This disease can develop from breathing in chemicals used in some industries. Also, as mentioned earlier, people who use 'vapes' and 'e-cigarettes' are also at risk.

Some toxic chemicals that can cause 'popcorn lung' include:

• Acetaldehyde
• Ammonia
• Chlorine
• Diacetyl - This is the main one.
• Formaldehyde
• Fumes from metal oxides
• Hydrochloric acid
• Sulfur mustard (Mustard gas or sulfur mustard) - This is a poisonous gas used in warfare.
• Nitrogen oxides
• Sulfur dioxide

• Due to some medical conditions:
• Respiratory tract infections: Examples include respiratory syncytial virus (RSV) , some types of pneumonia, and types of bronchitis.
• Stevens-Johnson Syndrome : This is a severe allergic reaction that affects the skin and mucous membranes.
• Rheumatic conditions like gout: For example, 'Rheumatoid Arthritis' .
• Organ transplant recipients: This risk is particularly high in lung transplant recipients. It can also occur in bone marrow transplant recipients.

How common is 'popcorn lung'?

Popcorn lung is actually a rare condition . However, as mentioned earlier, it can develop in anyone due to exposure to toxic chemicals or certain infections, so it's important for all of us to be aware of it.

This disease is especially common among people who have had a lung transplant. About 50% of people who have had a lung transplant will develop a condition called bronchiolitis obliterans syndrome (BOS) within five years. This is actually a major form of transplant rejection. It may initially look like an infection.

This disease does not progress in the same way for everyone. Some people may have a longer initial course of the disease, while others may develop the disease more quickly. A lung function test called spirometry can measure the severity of the disease.

What are the symptoms of 'popcorn lung'?

The symptoms of this disease may not appear immediately. However, the following are the most common symptoms:

• Cough: Coughing occurs, especially during and after exercise. Sometimes it can even produce mucus. This cough can be a dry cough , meaning a cough without mucus.
• Dyspnea: This is also more common during and after exercise. Be aware if you experience shortness of breath when walking for a short distance or climbing stairs.
• Wheezing.
• Feeling very tired.
• Fever.
• Night sweats.
• A skin rash can sometimes be seen.

Remember, these symptoms can also be seen in other respiratory illnesses. Therefore, if you have these symptoms, it is best to seek medical advice immediately.

What causes 'popcorn lung'?

The most important thing is that 'popcorn lung' is not a contagious disease . This means that you cannot catch it from someone else, nor can you pass it on to someone else.

This is mainly caused by inhaling toxic chemicals, as mentioned earlier. Exposure to chemicals like diacetyl can occur at work or through vaping. The various chemicals in e-cigarettes can damage the tissues of our lungs. According to some opinions, this effect can occur not only to the person who is vaping, but also to those around them who are inhaling the smoke.

For people who have had a lung transplant, this disease can occur even without exposure to any chemicals or infection.

How does a doctor diagnose 'popcorn lung'?

When you go to see a doctor, he or she will first ask you about your medical history and the symptoms you are experiencing. Since symptoms such as shortness of breath and fatigue are also common in other diseases, the doctor will need to perform some tests to diagnose this condition.

Some of those tests are:

• Chest X-ray or CT scan: These can check the condition of the lungs.
• Lung function tests: Tests like 'spirometry' can check how well your lungs are working.
• Bronchoscopy: This involves passing a small camera-equipped tube down the windpipe to examine the inside of the lungs.
• Lung biopsy: Sometimes, a small piece of tissue from the lung needs to be taken and examined under a microscope to confirm the diagnosis. This is the best way to definitively diagnose the disease .

What are the treatments for 'popcorn lung'?

Unfortunately, the damage to the lungs caused by 'popcorn lung' is irreversible . That is, the damage cannot be reversed. However, if the disease is detected early, treatment can help prevent further progression.

The first thing you need to do is stop your exposure to the chemicals that cause the disease. If you are exposed to these chemicals at work, you should definitely use protective equipment. If you are a smoker or vaper, you should stop immediately.

Some of the treatments for 'popcorn lung' include:

• Corticosteroids: These are a type of medication that is given to reduce inflammation. For example, Prednisone.
• Inhalers: These help make breathing easier. For example, an inhaler containing Albuterol.
• Oxygen therapy: Providing oxygen to those with low blood oxygen levels.
• Lung transplant: This is only recommended in the most severe and critical cases.

Side effects of 'corticosteroids'

Although corticosteroids are great for reducing inflammation, they can cause some side effects. Some of them include:

• Weight gain.
• Mood changes.
• Restlessness, agitation.
• Development of diabetes or worsening of existing diabetes.
• Insomnia.

Therefore, when a doctor prescribes this medication, they will discuss the pros and cons with you.

How can I reduce the risk of developing 'popcorn lung'?

To stay safe from this disease, we need to take care of our lungs from the beginning. Here are some things you can do:

• Avoid tobacco and e-cigarette use. Also, stay away from secondhand smoke and areas with high air pollution.
• Avoid infections whenever possible. Some infections can damage your lungs. Stay protected by getting vaccinated as directed by your doctor.
• If you work with hazardous chemicals, always wear Personal Protective Equipment (PPE).

What is the future of someone with 'popcorn lung'?

In fact, there is no permanent cure for popcorn lung. It requires lifelong medical treatment and care to control the symptoms. Sometimes the symptoms may not respond well to treatment.

If I have 'popcorn lung', how do I take care of myself?

If you have this disease, be careful about these things:

• Stay away from air pollution and tobacco smoke.
• Stay away from people who have infections. Make it a habit to wash your hands regularly.
• If you develop any infection, even a dental infection, seek treatment immediately.
• Take the medicine exactly as prescribed by the doctor.
• If you have symptoms of gastroesophageal reflux disease (GERD) , tell your doctor about it, as these conditions can cause further damage to your lungs if left untreated.
• When living with a chronic illness like this, joining a support group can be helpful. Sometimes, talking to people who are going through the same problems as you can give you answers and ideas that you wouldn't get anywhere else.

When should I see a doctor?

If you have difficulty breathing that cannot be controlled with your rescue inhaler, see a doctor immediately. Also, if you develop new symptoms or if your symptoms worsen, seek medical advice immediately.

What is the difference between 'bronchiolitis obliterans' and 'bronchiolitis obliterans organizing pneumonia' (BOOP)?

Although both are diseases that affect the small airways of the lungs, bronchiolitis obliterans and bronchiolitis obliterans organizing pneumonia (BOOP) are two different diseases. BOOP can be caused by infections, certain medications, or other diseases. The new name for BOOP is cryptogenic organizing pneumonia (COP) , especially when no cause can be found. The main symptom of BOOP is a persistent cough that does not produce mucus.

Will 'popcorn lung' heal on its own?

The short answer is: No. Bronchiolitis obliterans is an irreversible condition. Once the damage is done, it cannot be repaired. All we can do is try to stop the disease from getting worse. If left untreated, this disease can be fatal.

When you hear the name 'popcorn lung', you might think that this is just a made-up disease. But, it's not. It is a serious lung disease that needs to be managed throughout life. Therefore, it is very important to follow the advice of your doctor, especially to avoid exposure to harmful substances.

Finally, things to remember (Take-Home Message)

• 'Popcorn lung' is an irreversible disease that damages the delicate airways of the lungs.
• The main reason is inhaling toxic chemicals like diacetyl. Vaping is a big risk for this.
• If you have symptoms such as persistent cough, wheezing, or fatigue, especially if you are a vaper or work with chemicals, see a doctor immediately.
• The best way to prevent this disease is to avoid smoking and vaping, and to follow safe practices.
• If the disease develops, it will have to be managed for life according to the doctor's instructions.
