Breathing should feel natural, but when your lungs struggle, every breath can remind you how vital healthy airways are. At Gwinnett Pulmonary, we understand how different lung conditions—like asthma, COPD, or pulmonary fibrosis—can change the way air moves through your body.
We explore how these conditions block, restrict, or damage the lungs and what that means for your oxygen levels and energy. Whether caused by smoking, infection, or environmental exposure, these issues can limit how deeply you breathe and how well your lungs exchange oxygen.
We depend on our lungs to move oxygen into our blood and remove carbon dioxide. When disease or injury affects this process, breathing becomes harder, leading to symptoms like shortness of breath, wheezing, and chest tightness.
Understanding how healthy lungs work and what disrupts them helps us recognize and manage these problems early.
Our lungs work with the diaphragm and chest muscles to move air in and out. When we inhale, the diaphragm contracts and pulls downward, expanding the chest cavity.
This draws oxygen-rich air through the airways into tiny air sacs called alveoli. Inside the alveoli, oxygen passes into the blood while carbon dioxide moves out to be exhaled.
This gas exchange keeps our organs supplied with oxygen and removes waste gases. Healthy lungs stay flexible and transparent of excess mucus.
The airways remain open, and the lung tissue expands easily. When this balance is maintained, we breathe without effort and rarely notice the process.
Lung conditions interfere with airflow, gas exchange, or both. Diseases like asthma and chronic obstructive pulmonary disease (COPD) cause airway narrowing and inflammation, which make it difficult for air to move in or out.
Scarring from pulmonary fibrosis stiffens lung tissue, reducing its ability to expand. Infections such as pneumonia fill air sacs with fluid or mucus, limiting oxygen transfer.
These changes lead to dyspnea, or the feeling of breathlessness. We may also experience wheezing from narrowed airways or chest tightness from increased effort to breathe.
When oxygen levels drop, fatigue and dizziness can occur. Each condition affects breathing in specific ways, but all reduce how efficiently our lungs deliver oxygen.
Lung diseases often share symptoms that signal reduced lung function. Shortness of breath during activity or rest is one of the earliest signs.
Chronic cough, sometimes producing thick mucus, can indicate airway irritation or infection. Wheezing—a whistling sound during breathing—suggests narrowed airways.
Chest tightness or pain may accompany inflammation or trapped air. Some people notice breathlessness that worsens over time, especially with exertion.
| Symptom | Possible Cause |
| Shortness of breath | Airflow obstruction, low oxygen |
| Wheezing | Narrowed airways |
| Chronic cough | Irritation, infection, mucus buildup |
| Chest tightness | Air trapping, inflammation |
Recognizing these symptoms early helps us seek care and prevent further lung damage.
Obstructive lung diseases make it harder for air to move in and out of the lungs. They often cause shortness of breath, chronic cough, and wheezing due to narrowed airways or damaged air sacs.
These types of lung conditions usually develop over time and are closely linked to inflammation, smoking, and environmental exposure.
Chronic obstructive pulmonary disease, or COPD, includes long-term conditions that block airflow and make breathing difficult. The two primary forms are chronic bronchitis and emphysema.
In COPD, the bronchial tubes become inflamed and narrowed, while the air sacs lose their elasticity. This limits the amount of air we can exhale, trapping stale air in the lungs.
Common symptoms include:
Smoking is the leading cause of COPD. Long-term exposure to dust, chemicals, or fumes can also contribute.
Doctors often use lung function tests and chest imaging to confirm diagnosis and measure severity. Treatment focuses on opening the airways and reducing inflammation.
We may use bronchodilators, inhaled corticosteroids, and pulmonary rehabilitation to improve breathing and quality of life.
Asthma causes the airways to swell and tighten, making it harder for air to move through the lungs. The bronchial tubes become overly sensitive to triggers such as pollen, dust, smoke, or cold air.
During an asthma flare-up, the muscles around the airways contract, and mucus builds up. This leads to wheezing, coughing, and shortness of breath.
Asthma symptoms can vary in frequency and intensity. Some people experience mild episodes, while others have severe attacks that require urgent care.
Key management steps include:
With proper treatment and monitoring, most people with asthma can maintain normal activity levels.
Chronic bronchitis is a form of COPD marked by long-term inflammation of the bronchial tubes. This inflammation increases mucus production and narrows the airways.
A productive cough that lasts for at least three months in two consecutive years is a key sign of chronic bronchitis. The mucus buildup often causes morning coughing and frequent throat clearing.
Main causes include:
Over time, the constant irritation damages the airway lining and reduces airflow. Treatments aim to relieve symptoms and prevent further damage.
We often recommend smoking cessation, bronchodilators, and airway clearance techniques to improve breathing.
Emphysema damages the air sacs (alveoli) in the lungs, reducing their ability to exchange oxygen and carbon dioxide. The walls of the air sacs break down, creating larger but fewer spaces for air to move through.
This loss of surface area makes it difficult for oxygen to reach the bloodstream, leading to shortness of breath even at rest.
Typical signs include:
Smoking is the main cause of emphysema, but long-term exposure to pollution or dust can also play a role.
Treatment cannot reverse the damage, but inhaled medications, oxygen therapy, and pulmonary rehabilitation help us manage symptoms and slow progression. Avoiding smoke and irritants remains essential for protecting remaining lung function.
Restrictive and interstitial lung diseases limit how much air the lungs can hold. They often cause stiffening or scarring of lung tissue, which makes breathing difficult and reduces oxygen transfer into the blood.
These conditions can develop from inflammation, environmental exposure, or genetic factors.
Pulmonary fibrosis causes thickening and scarring of lung tissue. This scarring makes the lungs stiff and less able to expand during inhalation.
As a result, we may feel short of breath, especially during activity. Common causes include autoimmune diseases, environmental exposures like asbestos or silica, and certain medications.
In some cases, the cause is unknown, which is called idiopathic pulmonary fibrosis (IPF). Doctors often diagnose pulmonary fibrosis using imaging tests, lung function tests, and sometimes a biopsy.
Treatment may include antifibrotic medications such as pirfenidone or nintedanib, oxygen therapy, and pulmonary rehabilitation. These treatments do not reverse scarring but can slow disease progression.
| Key Feature | Description |
| Main Problem | Scarring and stiffening of lung tissue |
| Common Symptom | Shortness of breath and dry cough |
| Main Treatments | Antifibrotic drugs, oxygen therapy, rehab |
Interstitial lung disease refers to a group of about 200 conditions that cause inflammation and scarring in the lung’s interstitium, the tissue around the air sacs. This scarring limits oxygen movement into the bloodstream.
ILD can result from autoimmune disorders, long-term exposure to irritants, or unknown causes. Some examples include hypersensitivity pneumonitis, sarcoidosis, and connective tissue disease–related ILD.
Symptoms often include chronic cough, fatigue, and breathlessness. Over time, the lungs lose elasticity, and breathing becomes more difficult.
Diagnosis usually involves high-resolution CT scans and pulmonary function tests. Management focuses on slowing inflammation and fibrosis through corticosteroids, immunosuppressants, or antifibrotic agents.
Lymphangioleiomyomatosis, or LAM, is a rare chronic lung disease that primarily affects women of childbearing age. It involves abnormal growth of smooth muscle cells in the lungs, which blocks airways and damages lung tissue.
The buildup of these cells leads to air cysts, lung collapse (pneumothorax), and reduced airflow. LAM can occur on its own or as part of a genetic condition called tuberous sclerosis complex (TSC).
Symptoms include shortness of breath, chest pain, and fatigue. Diagnosis relies on CT imaging and sometimes genetic or blood testing.
Treatment may include sirolimus (rapamycin) to slow cell growth, oxygen therapy, and management of lung collapse.
| Feature | Detail |
| Affected Group | Women of reproductive age |
| Cause | Abnormal smooth muscle cell growth |
| Common Treatments | Sirolimus, oxygen therapy, symptom management |
We often face lung infections that spread through the air or by close contact. These illnesses can cause inflammation, coughing, and breathing problems that range from mild to severe.
Pneumonia occurs when bacteria, viruses, or fungi infect the air sacs in the lungs. These sacs fill with fluid or pus, making it hard for us to breathe normally.
Common symptoms include fever, chills, cough with mucus, and chest pain that worsens when breathing deeply. Some people also feel tired or short of breath even at rest.
Doctors diagnose pneumonia through a chest X-ray, blood tests, or sputum analysis. Treatment depends on the cause.
Bacterial pneumonia usually needs antibiotics, while viral pneumonia often improves with rest, fluids, and over-the-counter medicine. We can lower our risk by getting vaccinated, washing our hands often, and avoiding smoking, which weakens lung defenses.
Tuberculosis (TB) is caused by Mycobacterium tuberculosis, a bacterium that mainly affects the lungs. It spreads through the air when someone with active TB coughs or sneezes.
Typical symptoms include a persistent cough lasting more than three weeks, fever, night sweats, fatigue, and chest pain. Some people also lose weight without trying.
Doctors confirm TB with a skin test, blood test, or chest imaging. Treatment involves a combination of antibiotics taken for several months.
Skipping doses can lead to drug-resistant TB, which is harder to treat. We can help prevent TB by testing people at risk, completing prescribed treatments, and improving ventilation in shared spaces.
The flu is a contagious viral infection that affects the nose, throat, and lungs. It spreads easily through droplets when we talk, sneeze, or cough.
Symptoms often appear suddenly and include fever, body aches, dry cough, sore throat, and fatigue. Some people also experience chest discomfort or shortness of breath.
Most healthy adults recover within a week. Older adults, young children, and those with chronic illnesses face higher risks of complications like pneumonia.
Antiviral medications can shorten recovery if started early. The flu vaccine remains our best protection and should be taken every year.
Other infections, such as bronchitis, COVID-19, and respiratory syncytial virus (RSV), also affect the lungs and airways. They can cause cough, fever, congestion, and chest tightness.
These illnesses vary in severity but often spread the same way—through airborne droplets or contaminated surfaces.
Treatment usually focuses on rest, hydration, and symptom relief. Some viral infections may require antiviral treatment, while bacterial infections need antibiotics.
We can reduce our risk by practicing good hygiene, wearing masks when ill, and staying home when we have a fever or cough to prevent spreading infection.
Several severe lung disorders can damage breathing ability and overall health. These conditions may cause chest pain, fatigue, or weight loss and often require early detection for better outcomes.
Lung cancer starts when abnormal cells grow uncontrollably in lung tissue. It is one of the leading causes of cancer-related deaths worldwide.
The two main types are non–small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).
Common symptoms include chronic cough, chest pain, shortness of breath, coughing up blood, and unexplained weight loss. Smoking remains the top risk factor, but exposure to radon, asbestos, or air pollution can also increase risk.
Diagnosis often involves imaging tests such as chest X-rays or CT scans, followed by a biopsy. Treatment may include surgery, radiation, chemotherapy, or targeted therapy depending on the cancer stage and type.
A pulmonary embolism (PE) happens when a blood clot blocks an artery in the lungs. The clot usually forms in the legs as a deep vein thrombosis (DVT) and travels through the bloodstream to the lungs.
Symptoms can appear suddenly and include sharp chest pain, shortness of breath, rapid heartbeat, and lightheadedness. Severe cases may cause fainting or collapse.
Doctors diagnose PE using CT scans, blood tests, or ultrasound imaging of the legs. Treatment focuses on dissolving or preventing new clots with anticoagulant medication.
In emergencies, thrombolytic drugs or surgical removal of the clot may be needed. Quick medical attention is essential to prevent heart strain or respiratory failure.
Pulmonary hypertension (PH) is high blood pressure in the arteries that carry blood from the heart to the lungs. This extra pressure makes the heart work harder and can eventually weaken it.
People with PH may experience shortness of breath, chest pain, fatigue, and swelling in the legs or abdomen. The condition can result from chronic lung disease, heart problems, or blood clots.
Diagnosis often includes echocardiograms, right heart catheterization, and blood tests. Treatment aims to lower lung pressure and improve oxygen flow using medications such as vasodilators or diuretics.
In advanced cases, oxygen therapy or lung transplantation may be required.
Mesothelioma is a rare cancer that forms in the lining of the lungs, called the pleura. It is most often linked to asbestos exposure, which can occur decades before symptoms appear.
Early signs include chest pain, persistent cough, shortness of breath, and unexplained weight loss. As the disease progresses, fluid may build up around the lungs, making breathing more difficult.
Doctors use imaging scans and tissue biopsies to confirm diagnosis. Treatment may include surgery to remove affected tissue, chemotherapy, or radiation therapy to control tumor growth.
Some lung conditions appear suddenly and require urgent care, while others are inherited or develop slowly over time. These illnesses can harm breathing by limiting airflow, damaging lung tissue, or interrupting regular oxygen exchange.
A pneumothorax occurs when air leaks into the space between the lung and chest wall. This pressure causes the lung to collapse partially or entirely.
It can result from chest injury, medical procedures, or lung diseases such as COPD.
Common symptoms include sudden chest pain and shortness of breath. A collapsed lung can range from mild to life-threatening depending on how much air is trapped.
We diagnose pneumothorax with a chest X-ray or CT scan. Treatment depends on severity.
Small pneumothoraces may heal on their own, while larger ones often need a chest tube to remove trapped air. In some cases, surgery helps prevent recurrence.
Prompt medical care reduces the risk of complications like infection or repeated lung collapse.
Cystic fibrosis (CF) is a genetic disorder that affects the lungs and digestive system. It causes the body to produce thick, sticky mucus that clogs airways and traps bacteria.
This leads to chronic lung infections, inflammation, and progressive lung damage. We often identify CF in childhood through genetic testing or a sweat chloride test.
Symptoms include persistent coughing, frequent lung infections, and difficulty gaining weight.
Treatment focuses on clearing mucus and preventing infection. Common therapies include:
With early care and daily management, people with CF can maintain better lung function and quality of life.
Pulmonary alveolar proteinosis (PAP) is a rare disease where protein-rich material builds up in the air sacs (alveoli) of the lungs. This buildup blocks oxygen from moving into the blood, causing shortness of breath and fatigue.
There are three main types: autoimmune, secondary, and congenital. The autoimmune form is most common and occurs when antibodies interfere with how the lungs clear surfactant.
We diagnose PAP with imaging tests and lung biopsy. Treatment often includes whole-lung lavage, a procedure that washes out the excess material.
Some patients receive medications that boost immune function or target antibodies involved in the disease. Because PAP can recur, regular monitoring and follow-up are essential.
Sleep apnea is a disorder where breathing repeatedly stops and starts during sleep. The most common type, obstructive sleep apnea (OSA), happens when throat muscles relax and block the airway.
Less common is central sleep apnea, where the brain fails to send proper signals to breathing muscles.
Key symptoms include loud snoring, gasping during sleep, and daytime fatigue. Untreated apnea increases the risk of high blood pressure, heart disease, and stroke.
Diagnosis involves a sleep study that records breathing patterns, oxygen levels, and sleep stages.
Treatment options include:
Managing sleep apnea improves oxygen flow, sleep quality, and long-term health.
We can ease breathing difficulties and improve daily function by combining medical treatment, lifestyle changes, and supportive therapies.
We use several proven methods to manage breathing problems caused by chronic lung diseases like COPD, asthma, or pulmonary fibrosis. Pulmonary rehabilitation plays a central role.
It combines exercise, breathing training, and education to help us build endurance and reduce shortness of breath. Medications such as bronchodilators, corticosteroids, or mucolytics help open airways and control inflammation.
When used correctly, these treatments improve oxygen flow and reduce coughing or wheezing. We also teach breathing techniques like pursed-lip and diaphragmatic breathing.
These methods slow breathing, improve oxygen exchange, and reduce anxiety during flare-ups. For individuals with heart failure or other comorbidities, treatment plans are carefully adjusted to ensure safety during exercise and medication use.
Regular follow-ups allow our care team to track progress and modify therapies as needed.
| Treatment Type | Purpose | Example |
| Medication | Reduce airway inflammation | Inhaled corticosteroids |
| Pulmonary Rehab | Build strength and endurance | Supervised exercise sessions |
| Breathing Techniques | Improve oxygen use | Pursed-lip breathing |
When lung function drops below normal levels, supplemental oxygen may become necessary. It helps maintain safe blood oxygen levels, especially during activity or sleep.
We prescribe oxygen therapy based on test results such as arterial blood gases or pulse oximetry readings. The goal is to prevent hypoxemia, which can strain the heart and other organs.
Oxygen can be delivered through portable concentrators, tanks, or liquid systems. Portable options allow us to stay active outside the home, promoting better mobility and independence.
Safety is essential. We avoid smoking or open flames near oxygen equipment and ensure proper storage.
Our team provides training on device use, cleaning, and maintenance to prevent accidents or equipment failure. Regular monitoring ensures that oxygen flow rates remain effective as conditions change.
Adjustments are made under medical supervision to maintain comfort and safety.
Lifestyle changes greatly influence how well we manage lung disease. Quitting smoking is the most effective step we can take to protect our lungs and slow disease progression.
We encourage balanced nutrition to maintain strength and energy. For those underweight, high-calorie foods support recovery, while those managing obesity benefit from portion control to reduce breathing effort.
Exercise improves circulation and muscle function, even for people with limited mobility. Gentle activities like walking or stationary cycling can enhance endurance when done safely.
Avoiding air pollutants, allergens, and respiratory infections is also key. We recommend annual flu and pneumonia vaccines and frequent handwashing.
Emotional health matters too. Relaxation techniques, counseling, or support groups help us manage stress and stay motivated through treatment.
We should contact a healthcare provider if symptoms suddenly worsen or new issues appear. Warning signs include increased shortness of breath, chest pain, swelling in the legs, or a bluish tint to lips or fingers.
Frequent flare-ups, persistent coughing, or reduced ability to perform daily activities may indicate that treatment needs adjustment.
If we use supplemental oxygen, a sudden drop in oxygen saturation or equipment malfunction requires immediate attention.
People with heart failure should also watch for rapid weight gain or severe fatigue, as these may signal fluid buildup.
