Do you sometimes feel a little short of breath, a tightness in your chest? Or do you have a cough that's worse in the morning, or do you feel tired? These may not just be symptoms of a cold. They may be signs of a lung condition called Bullous Emphysema , which you should be concerned about. So, let's talk about this in a little more detail today, like you're talking to a friend, okay?
What is Bullous Emphysema?
Simply put, Bullous Emphysema is a type of lung disease called emphysema . Emphysema occurs when the walls of the tiny air sacs inside your lungs, called alveoli , become damaged. Remember, these alveoli are the ones that do the most important job of taking in oxygen and releasing carbon dioxide when we breathe.
Now, in bullous emphysema, what happens is that the walls of those alveoli get damaged, and they swell up and form large air sacs, like balloons. We call these bullae . These bullae can be larger than a centimeter.
When this cyst forms, it interferes with the lungs' ability to function properly. It becomes difficult for the alveoli to exchange oxygen and carbon dioxide. This condition can occur in one or both lungs. However, even if this cyst forms in one lung, it can interfere with the other lung's ability to inflate, which means breathing. Sometimes, if this cyst becomes very large, the lung can collapse, causing a condition called Vanishing Lung Syndrome . Although this can cause permanent damage to the lungs, proper treatment can control this condition and increase your life expectancy.
Who is more likely to develop this condition?
In fact, anyone can develop bullous emphysema, regardless of age, race, or gender. However, it is most often associated with chronic obstructive pulmonary disease (COPD) , a lung disease caused by smoking. Also, if you have certain genetic conditions, your risk is higher. For example:
- Alpha-1 antitrypsin deficiency
- Ehlers-Danlos syndrome
- Marfan syndrome
In addition, people infected with the Human Immunodeficiency Virus (HIV) are also at increased risk of developing bullous emphysema.
How common is this? Why does this occur?
Worldwide, more than 5% of the population and more than 12% of adults over the age of 30 are reported to have bullous emphysema. It is also the third leading cause of death in countries like the United States. So, this is not something to be taken lightly.
Now let's see why this happens.
The main cause of bullous emphysema is smoking . The chronic inflammation caused by cigarette smoke damages the walls of your alveoli. This causes the air sacs to enlarge, obstructing the movement of oxygen and carbon dioxide.
Besides smoking, there are other causes:
- Smoking crack cocaine or marijuana.
- Intravenous drug use.
- The aforementioned genetic conditions can also cause the alveolar walls to become weak and damaged, leading to bullous emphysema.
What are the symptoms of this?
The main and most common symptom of bullous emphysema is shortness of breath . This means that you feel short of breath, not only when you are slightly tired, when climbing stairs, but sometimes even when you are just standing still.
There are other common symptoms:
- Feeling of chest pain or tightness.
- Having a cough (this is often worse in the morning).
- Feeling tired and exhausted all the time (Fatigue).
- The food is tasteless.
- Nausea.
- Trouble breathing.
However, some people may have bullous emphysema but not show any symptoms. If the bullae become very large, we call them giant bullae , then symptoms may become more severe.
When you see a doctor, he or she will look for signs like these while examining you:
- A barrel-shaped chest.
- Clubbed fingers.
- Hearing your heartbeat loudly due to pulmonary hypertension.
- Swelling (Edema).
- Wheezing.
How do you recognize this exactly?
Your doctor will first ask you about your symptoms, your health history, and whether anyone in your family has had similar conditions. Then they will do a physical exam.
If bullous emphysema is suspected, your doctor will order pulmonary function testing (PFT) . These tests check how well your lungs are moving air and whether the bullae are obstructing the flow of air.
As part of these tests, you may have a spirometry test. This involves you breathing through a tube into a machine (spirometer). This measures how much air moves in and out of your lungs when you breathe in and out.
Additionally, your doctor may suggest imaging tests to check for enlarged or damaged alveoli. These may include:
- Chest X-ray: This can help determine if there are any bullae and where they are in the lungs.
- CT scan: This can help determine the exact location, number, and size of the cyst.
Other tests may be suggested, for example:
- Blood tests: Check for carbon dioxide buildup in the lungs, making the blood acidic (this is called respiratory acidosis ), or low oxygen levels.
- Complete blood count (CBC): Checks for low hemoglobin levels.
- Electrocardiogram (EKG): To check for any heart effects caused by lung disease, such as right ventricular hypertrophy or right atrial enlargement .
Your doctor can also check if you have Alpha-1 antitrypsin deficiency through blood tests.
Is there a complete cure for this?
Unfortunately, there is no cure for bullous emphysema. This means that once it develops, it cannot be reversed. But don't worry! There are treatments that can help you live with the symptoms and stop the disease from getting worse.
So what are the treatments?
To help control your symptoms, your doctor may prescribe medications called bronchodilators . These are usually inhaled through an inhaler . Bronchodilators work by relaxing the muscles in your airways, making it easier for air to pass into your lungs, and reducing shortness of breath.
Imagine, these medicines work like widening a congested road a little, making it easier for vehicles to pass through.
If you have severe symptoms or a lung infection, you may also be given antibiotics or corticosteroids for a short period of time.
If your oxygen levels are low, your doctor may suggest supplemental oxygen therapy , which involves giving your body extra oxygen through a tube placed inside your nostrils or a mask placed on your face.
In some cases, especially if you have giant bullae , the difficulty breathing is very severe, or the disease can cause other complications, for example:
- Collapsed lung (Pneumothorax)
- Coughing up blood (Hemoptysis)
- Lung infections
If things like this happen, you may need surgery.
Types of surgery for bullous emphysema:
- Bullectomy: In this procedure, the surgeon removes the bulla (air sac) from your lung. This can be done either as an open surgery (Thoracotomy) or as a minimally invasive procedure (Video-assisted thoracic surgery - VATS).
- Bronchoscopic lung volume reduction (BLVR): In this minimally invasive procedure, the surgeon inserts a valve into your lung and intentionally shrinks a portion of the lung.
- Lung volume reduction surgery (LVRS): In this, the surgeon removes damaged lung tissue so that the remaining tissue can function better.
If none of these treatments work, and if appropriate, your doctor may refer you for a lung transplant .
How can this risk be reduced?
The best thing you can do to reduce your risk of developing bullous emphysema is to not smoke, or if you smoke, to quit. Talk to your doctor about ways to help you quit smoking. We know it's not easy, but it's worth it for the health of your lungs.
What should you expect when living with this condition?
Bullous emphysema is a lifelong health condition. This means that once your lungs are damaged, they will never fully recover. However, the sooner you start treatment, the more likely you are to stop the condition from getting worse. Therefore, it is important to seek medical advice as soon as possible if you have symptoms.
How do I take care of myself?
You can manage your symptoms and live well. Finding the right treatment for you can greatly improve your quality of life.
It's also important to stay healthy and avoid serious health complications. So, talk to your doctor about the types of vaccines you may need, such as the flu vaccine, COVID vaccine, and Pneumococcus vaccine .
What time should I see a doctor?
If you notice any signs of bullous emphysema, or if you develop new symptoms, be sure to see a doctor.
If you have the following symptoms, it is essential to seek medical attention immediately:
- A blue or gray color to your lips or fingernails (cyanosis).
- Difficulty staying mentally alert.
- Increasing difficulty breathing.
- Rapid heartbeat (Tachycardia).
Breathlessness can be a scary thing. If you have bullous emphysema, you may feel like you're constantly struggling to breathe. Remember, smoking is the main cause. Also, certain genetic conditions can increase your risk. Quitting smoking is the best thing you can do to stop bullous emphysema from getting worse. Your doctor can suggest treatments that can help you breathe easier and make your daily life more manageable.
Remember the most important thing (Take-Home Message)
