Lung Diseases Overview
Lung diseases are some of the most common medical conditions in the world. Tens of millions of people have lung disease in the U.S. Alone. Smoking, infections, and genes cause most lung diseases.
Your lungs are part of a complex system, expanding and relaxing thousands of times each day to bring in oxygen and send out carbon dioxide. Lung disease can happen when there are problems in any part of this system.
Your windpipe (trachea) branches into tubes called bronchi, which in turn become smaller tubes throughout your lungs. Diseases that can affect these airways include:
Your airways branch into tiny tubes (bronchioles) that end in clusters of air sacs called alveoli. These air sacs make up most of your lung tissue. Lung diseases affecting your alveoli include:
The interstitium is the thin, delicate lining between your alveoli. Tiny blood vessels run through the interstitium and let gas transfer between the alveoli and your blood. Various lung diseases affect the interstitium:
The right side of your heart gets low-oxygen blood from your veins. It pumps blood into your lungs through the pulmonary arteries. These blood vessels can have diseases, as well.
The pleura is the thin lining that surrounds your lung and lines the inside of your chest wall. A tiny layer of fluid lets the pleura on your lung's surface slide along the chest wall with each breath. Lung diseases of the pleura include:
Your chest wall also plays an important role in breathing. Muscles connect your ribs to each other, helping your chest expand. Your diaphragm descends with each breath, also causing chest expansion. Diseases that affect your chest wall include:
How Lung Medicine Helps Fight Respiratory Infections
Lung problems can range from mild respiratory infections to severe conditions like pneumonia, chronic obstructive pulmonary disease (COPD), and lung cancer. These conditions can significantly impact a person's quality of life, making it essential to understand the best medicines for lungs and how they can aid in managing various lung problems.

Medication for Specific Lung Problems
Preventive Measures and Lifestyle Tips Lung problems can be managed effectively with the right combination of medication and lifestyle changes. From bronchodilators and steroids to antibiotics and antivirals, choosing the best medicine for lungs depends on the specific condition and its severity. Consult a healthcare provider for personalized treatment and medication recommendations.
What Is Chronic Obstructive Pulmonary Disease (COPD)?
Key takeawaysChronic obstructive pulmonary disease, commonly referred to as COPD, is a group of progressive lung diseases.
An estimated 32 million people in the United States have COPD. As many as half are unaware that they have it.
These diseases include emphysema and chronic bronchitis. Many people with COPD have both.
Untreated COPD can lead to a faster progression of the disease, heart problems, and worsening respiratory infections.
Keep reading to learn about the symptoms, causes, and how doctors treat COPD.
COPD makes it harder to breathe. Symptoms may be mild at first, and you might have shortness of breath. As it progresses, symptoms can become more constant to the point where it can become increasingly difficult to breathe.
You may experience wheezing and tightness in the chest or have excess sputum (saliva and mucus) production. Some people with COPD have acute exacerbations, which are flare-ups of severe symptoms.
Early symptoms
At first, symptoms of COPD can be quite mild. You might mistake them for a cold. Early symptoms include:
You might start making subtle changes, such as avoiding stairs and skipping physical activities.
Worsening symptoms
Symptoms can get progressively worse over time and usually become harder to ignore. As the lungs become more damaged, you may experience:
In later stages of COPD, symptoms may also include:
If you smoke or vape, your symptoms may be worse.
Emergency treatmentImmediate medical care is needed if:
There are different grading systems, and one grading system is part of the GOLD classification. The GOLD classification is used to determine COPD severity and help form a treatment plan.
There are four GOLD grades based on spirometry testing:
This is based on the spirometry test result of your FEV1. This is the amount of air you can breathe out of the lungs in the first second of a forced expiration. The lower your FEV1, the more severe the condition. The GOLD classification also considers your individual symptoms and history of acute exacerbations.
As the disease progresses, you're more susceptible to complications, such as:
Most people with COPD in the United States are at least 40 years old and have at least some history of smoking. The longer and more tobacco products you smoke, the greater your risk for COPD.
In addition to cigarette smoke, cigar smoke, pipe smoke, and secondhand smoke can cause COPD. Your risk of COPD is even greater if you have asthma and smoke.
Other causes
You can also develop COPD if you're exposed to chemicals and fumes in the workplace. Long-term exposure to air pollution and inhaling dust can also cause COPD.
In some countries, homes may be poorly ventilated. As a result, families may breathe fumes from burning fuel used for cooking and heating. This can also cause COPD.
There is no single test for COPD. The diagnosis is based on symptoms, a physical exam, and diagnostic test results.
When you visit the doctor, it may help to bring a list of your symptoms and when and how often they occur. Be sure to let your doctor know if you:
Exams and tests
During the physical exam, a doctor uses a stethoscope to listen to your lungs as you breathe. Based on this information, your doctor may order additional tests to get a more complete picture:
These tests can help determine if you have COPD or a different condition, such as asthma, a restrictive lung disease, or heart failure.
Medications for COPD can reduce symptoms and cut down on flare-ups. Finding the medication and dosage that works best for you may take some trial and error.
Inhaled bronchodilators
Medicines called bronchodilators help loosen tight muscles in your airways. They're typically taken through an inhaler or nebulizer.
Short-acting bronchodilators last 4 to 6 hours and you only use them when needed. For ongoing symptoms, long-acting versions can be used daily and last about 12 hours.
For people with COPD who experience shortness of breath or trouble breathing during exercise, the American Thoracic Society strongly recommends a long-acting beta-agonist (LABA) combined with a long-acting muscarinic antagonist (LAMA).
These bronchodilators work by relaxing tightened muscles in the airways, widening them for better air passage and helping the body clear mucus from the lungs. These two types of bronchodilators can be taken in combination via an inhaler or with a nebulizer.
Here's a list of recommended LABA/LAMA bronchodilator therapies:
Corticosteroids
Long-acting bronchodilators may be combined with inhaled glucocorticosteroids, but the current GOLD guidelines call for minimizing the use of inhaled corticosteroids in COPD treatment. Doctors may recommend their limited use and other treatments for people with severe symptoms and frequent exacerbations.
A glucocorticosteroid can reduce inflammation in the airways and lower mucus production.
The long-acting bronchodilator can relax the airway muscle to help the airways stay wider. Corticosteroids are also available in pill form.
Phosphodiesterase-4 inhibitors
This type of medication can be taken in pill form to help reduce inflammation and relax the airways.
The GOLD guidelines for COPD management recommend phosphodiesterase-4 inhibitors as an add-on therapy for people with persistent COPD symptoms and exacerbations despite treatment with bronchodilators and inhaled corticosteroids.
Doctors generally prescribe it for severe COPD with chronic bronchitis and a history of exacerbations.
Theophylline
This medication comes in pill form. It eases chest tightness and shortness of breath and may also help prevent COPD flare-ups.
Theophylline (Theo-24, Elixophylline, Theochron) is an older medication that relaxes the airway muscles. Because it may cause side effects, it's generally not a first-line treatment for COPD therapy.
Antibiotics and antivirals
Doctors may prescribe antibiotics or antivirals if you develop certain respiratory infections to help you recover.
Treatment can ease symptoms, prevent complications, and generally slow disease progression. Your healthcare team may include a lung specialist (pulmonologist) and physical and respiratory therapists.
Vaccines
To lower the risk of other respiratory infections, your doctor may recommend certain vaccines, including:
Oxygen therapy
If your blood oxygen level is too low, you can receive supplemental oxygen through a mask or nasal cannula to help you breathe better. A portable unit can make it easier to get around.
Surgery
Surgery is reserved for severe COPD or when other treatments haven't worked. These can include:
There's no specific diet for COPD, but a healthy diet is important for maintaining overall health. The healthier you are, the more you'll be able to help prevent complications and other health problems.
Consider eating a variety of nutritious foods from these groups:
Avoiding or limiting salt may also help, as salt causes the body to retain water, which can strain breathing.
COPD and lung cancer have multiple common risk factors. Smoking is the top risk factor for both diseases. Both are also more likely if you breathe secondhand smoke or are exposed to chemicals or other fumes in the workplace.
There may be a genetic predisposition to developing both diseases. Also, the risk of developing either COPD or lung cancer increases with age.
In some cases, people don't learn they have COPD until they receive a diagnosis of lung cancer.
Having COPD doesn't necessarily mean you'll get lung cancer. However, it does mean that you have a higher risk. That's another reason why, if you smoke, quitting is a good idea.
COPD generally reduces life expectancy, though the outlook varies considerably from person to person.
People with COPD who never smoked may have a modest reduction in their life expectancy, while former and current smokers are likely to have a larger reduction. However, your individual life expectancy can depend on other factors, including your overall health and the extent of lung damage.
Once you have a diagnosis, you'll need to start seeing your doctor regularly. You'll also need to take steps to manage your condition and make the appropriate changes to your daily life.
Treatment and lifestyle changes can help manage early symptoms of COPD and help you maintain a good quality of life for some time.
People with severe stages of COPD may not be able to care for themselves without assistance. COPD increases the risk of developing certain health conditions, including:
Besides smoking, your outlook depends on how well you respond to treatment and whether you can avoid serious complications. Your doctor is in the best position to evaluate your overall health and give you an idea about what to expect.
