Are your lungs getting tighter and harder to breathe? (Pulmonary Fibrosis) Let's talk about it!

Do you sometimes feel like you're gasping for breath when you climb stairs or walk a short distance? Or do you feel like you're not as tired as before, and now you feel very tired even when doing small tasks? One reason for these things could be a change in your lungs. That's right, Pulmonary Fibrosis, a condition that gradually hardens the lungs and makes it difficult to breathe, is what we're going to talk about today.

What exactly is Pulmonary Fibrosis?

Simply put, Pulmonary Fibrosis is the scarring and thickening of the tissue inside your lungs. Think of it like a scar on the skin when you get an injury, something similar happens inside the lungs. This belongs to a group of lung diseases called interstitial lung disease. What happens here is that the smallest air sacs in our lungs, the places where oxygen enters when we breathe, we call them `(alveoli)`, and the tissue around those `(alveoli)` is damaged. Now look, the lungs are like a sponge. They inflate when we breathe in, and they contract when we breathe out. But when this condition (Pulmonary Fibrosis) occurs, the tissues in the lungs become stiff and hard, so they can't inflate or contract as well as they used to. That's when it becomes difficult to breathe, and you catch your breath . Even daily tasks that used to be easy can now feel very tiring.

The most important thing is that this condition called (Pulmonary Fibrosis) is permanent , which means it is difficult to completely cure. Also, it can gradually get worse over time (progressively worse) . We call that `(progressive pulmonary fibrosis)`.

Can the lungs become stiff for no reason? What is Idiopathic Pulmonary Fibrosis?

Yes, sometimes the cause of this lung disease is not found . That's what we call `(Idiopathic Pulmonary Fibrosis)` for such cases. The word "idiopathic" means "of unknown cause." Most of the time, most of the patients with (Pulmonary Fibrosis) have this `(Idiopathic Pulmonary Fibrosis)` condition.

How do you know if you have Pulmonary Fibrosis? What are the symptoms?

The symptoms of this disease may vary slightly from person to person, but there are some common symptoms:

• Shortness of breath : Difficulty breathing, especially during or after light exercise, doing a task, or after finishing.
• Short, shallow breaths: Taking quick, small breaths, as if unable to fill your chest.
• Persistent dry cough : A cough that does not produce mucus and does not subside over time.
• Tired for no reason (Fatigue): Feeling tired all the time, even if you sleep well or don't do much work.
• Unexplained weight loss : Simply losing weight without dieting.
• Clubbed fingers: Some people's fingers and toes may become swollen and enlarged, resembling a drumstick.
• Skin discoloration (Cyanosis): When there is not enough oxygen in the blood, the lips, around the eyes, and fingernails may turn blue, gray, or white.

If you have one or more of these symptoms, it is best to seek medical advice.

Why does this (Pulmonary Fibrosis) occur? What are the causes?

Experts believe that pulmonary fibrosis occurs when the lungs are damaged or inflamed, and the process doesn't heal properly. This means that when the lungs try to heal themselves, something goes wrong and the scar tissue forms. There are several specific causes that can contribute to this:

• Connective tissue diseases : If you have diseases like Rheumatoid Arthritis (RA), Lupus, or Scleroderma, these can also affect your lungs .
• Environmental exposures: Long-term exposure to certain dusts and chemicals can damage the lungs. Examples include asbestos, silica, and beryllium. Hypersensitivity pneumonitis, an allergy to certain molds, bacteria, bird feathers, or dander, can also cause this condition.
• Granulomatous diseases: Conditions such as sarcoidosis or Langerhans cell histiocytosis.
• Certain medications or treatments: Some medications such as amiodarone for heart disease, nitrofurantoin for urinary tract infections, methotrexate for cancer and arthritis, and radiation therapy for cancer can also damage the lungs.
• Smoking: Smoking is very harmful to the lungs. It is also a major cause of Pulmonary Fibrosis.

However, as mentioned earlier, in many cases, a specific cause cannot be found.

Who is at higher risk of developing Pulmonary Fibrosis?

In addition to the reasons mentioned above, some other people are at slightly higher risk of developing this disease:

• For those over 65 years of age.
• For men, more than for women.
• If someone in the family has Pulmonary Fibrosis, there may be a genetic influence.
• For people with certain genetic conditions (DNA changes) that cause diseases. For example, a very rare bone marrow disorder called dyskeratosis congenita.

What other complications can occur due to Pulmonary Fibrosis?

When lung tissue becomes damaged, it can't properly deliver oxygen to the rest of the body. This causes our heart to work harder. This can lead to various complications:

• Decreased oxygen levels in the blood (hypoxemia) and lack of oxygen to the tissues (hypoxia).
• Pulmonary hypertension.
• Collapsed lung.
• Frequent lung infections.
• Complete respiratory failure.
• Heart failure.

This is why it is important to see a doctor immediately and seek treatment if you have symptoms.

How do you diagnose pulmonary fibrosis? What tests are done?

Several tests are needed to confirm the diagnosis of pulmonary fibrosis. Your doctor will first listen to your lungs and ask about your symptoms. Then they will do tests to see how well your lungs are working. They will also check for other heart or lung conditions that may be causing your symptoms. The most common tests are:

• Chest X-ray: Check the general condition of the lungs.
• High-resolution CT (HRCT) scan: This can show the scarring of the lungs very clearly.
• Pulmonary function tests (PFTs): These measure how well you can breathe in and out, and how much air your lungs can hold.
• Blood tests: Tests like arterial blood gas to check the oxygen level in the blood, as well as to check for other diseases.
• Bronchoscopy: A test in which a small camera with a tube attached to it is inserted through the nose or mouth to look inside the lungs. A tissue sample (biopsy) may also be taken at this time.
• Biopsy: A small piece of tissue is taken from the lungs and examined under a microscope.

Sometimes, your doctor may also recommend an echocardiogram to check for heart problems.

Can Pulmonary Fibrosis be completely cured? What treatments are available?

Unfortunately, there is currently no cure for pulmonary fibrosis. But don't worry. Current treatments can help control symptoms, slow the progression of the disease, and improve your quality of life . The main treatments used are:

• Antifibrotic medications: Medications such as Nintedanib (OFEV®) or Pirfenidone (Esbriet®) help to slow down the rate of lung scarring and preserve lung function.
• Corticosteroids: These are sometimes used to reduce inflammation in the lungs.
• Oxygen therapy: If your blood or tissues are not getting enough oxygen, your doctor may tell you to take supplemental oxygen. This is given through a nasal cannula or a face mask.
• Pulmonary rehabilitation: This involves special breathing exercises and physical exercises that help strengthen your lungs and make breathing easier.
• Lung transplant: Some patients with Pulmonary Fibrosis may be considered for a lung transplant if the disease is severe.
• Clinical trials: If you're interested, you can also take part in research studies on new drugs and treatments. Ask your doctor about this.

In addition, if there is another disease that is causing the development of Pulmonary Fibrosis (e.g., `(autoimmune disease)`), it will need to be treated, or if there are conditions that make the lung congestion worse (e.g., `(GERD)` - gastric distress), you will also need to take medication for that.

If I have Pulmonary Fibrosis, how should I take care of myself?

(Pulmonary Fibrosis) It can be a little harder for a person with pulmonary fibrosis to fight off infections and recover. Therefore, it is very important to wash your hands often with soap and water, keep your surroundings clean, and stay away from crowded places as much as possible (especially during flu and cold seasons and during the COVID pandemic). Also, it is essential to get the vaccinations recommended by your doctor. These vaccines help protect against diseases such as pneumonia, influenza, RSV, and COVID.

When should I see a doctor?

If you have difficulty breathing or feel tired more easily than before, see a doctor immediately. Because if you identify and start treatment for these conditions early, you can slow down the progression of the disease.If you already have a connective tissue disease or granulomatous disease, talk to your doctor about ways to reduce your risk of developing pulmonary fibrosis.

When do you need to go to the Emergency Treatment Unit (ETU) ?

If any of the following symptoms occur, call 911 or go to the nearest emergency room immediately:

• Sudden, severe difficulty breathing.
• Severe chest pain.
• Confusion or altered mental state.
• A blue discoloration of the skin, lips, or fingernails.

What should I ask my doctor?

It will be helpful for you to ask these questions when you visit the doctor:

• "Doctor, what's causing my lungs to tighten like this?"
• "What treatment options do I have?"
• "How should I use these medications?"
• "When should I come see the doctor next?"
• "Am I eligible for a lung transplant?"

It is very important to ask questions like these and gain a better understanding of your situation.

Can Pulmonary Fibrosis be prevented?

We cannot prevent many of the causes of pulmonary fibrosis. However, there are some things we can do to reduce the damage to the lungs caused by environmental factors:

• Stay away from things that are harmful to the lungs (e.g. asbestos, metal dust, chemicals) as much as possible. If you absolutely have to work with such things, use a special respirator.
• Stay away from things that can cause long-term allergies (e.g., hay, grains, bird droppings, feathers, and some air conditioning systems). Use a respirator if you work with these.
• If you smoke, stop immediately, or never start.

If I have Pulmonary Fibrosis, what should I expect?

This scarring of the lungs is almost permanent (except in rare cases, when it is caused by a drug and caught early). If you have another underlying condition, controlling that condition can help reduce further damage to your lungs. If no cause can be found, your doctor will try to treat your symptoms while trying to prevent further damage. It is difficult for doctors to predict exactly how pulmonary fibrosis will progress. For some people, symptoms may develop slowly over a period of years. For others, the disease may progress rapidly and become severe within a few months.

How long can you live with Pulmonary Fibrosis?

The average life expectancy for someone with the most common condition, ``Idiopathic Pulmonary Fibrosis,'' was usually three to five years. However, with recent advances in treatment, life expectancy for people with Pulmonary Fibrosis has increased slightly. So don't worry.

Are there stages of Pulmonary Fibrosis?

There is no officially recognized "staging" system for pulmonary fibrosis. However, some doctors may classify the disease as "mild," "moderate," "severe," or "very severe" based on your symptoms, lung function test results, and scans.

At what age does Pulmonary Fibrosis usually begin?

Pulmonary Fibrosis is most often diagnosed in people over the age of 65.

Finally, things to remember (Take-Home Message)

Finding out that you have Pulmonary Fibrosis can be a life-changing experience. It can be overwhelming and uncertain about the future. At times like these , having a support system from your loved ones, family, and others with the same condition can be invaluable.

The important thing is that every person with pulmonary fibrosis is different. No one can predict exactly what your future will be like. Current treatments can help slow the progression of the disease, control symptoms, and improve your quality of life. So, be honest with your doctor about what to expect and what you can do about your condition. It's also important to stay positive.
