Your respiratory system (made up of your airways and lungs) is one of the most critical physical systems allowing your body to function and keep you alive and well. Whether you’re in perfect health or are living with a lung condition, there are many things you can do to protect your lungs and stay as healthy as you can be.
Below you’ll find information about common diseases of the respiratory system, including overviews, risk factors, management, and commonly prescribed medications.
Chronic obstructive pulmonary disease, also called COPD, is a group of diseases that include emphysema and chronic bronchitis. COPD causes airflow obstruction that leads to difficulty with breathing. In 2018, 15.7 million Americans were reported to have COPD, but these numbers are probably underestimated.
Common risk factors for COPD include:
Symptoms of COPD include:
COPD is diagnosed through spirometry testing. Spirometry testing is noninvasive and simple. It consists of blowing into a mouthpiece connected to a spirometer, a machine that determines the severity of air flow obstruction compared to people your age. Spirometry can determine if you have COPD and how severe it is.
COPD medications can decrease shortness of breath, help with coughing and wheezing, and prevent flare-ups that could be life threatening. Maintenance medications are used daily to help control your COPD and decrease the frequency of flare-ups. Rescue medications are taken when acutely experiencing symptoms. It’s important to check medication expiration dates, especially for rescue medications, as you may go awhile between usages and expired medications can be less effective.
It is a common long-term disease in children but also can occur in adults. In some children, symptoms will improve with age to a point where it appears they no longer have the disease but for some of these individuals, symptoms can return later in life.
Risk factors for asthma include:
Symptoms of asthma include:
Asthma can be difficult to diagnose. Your doctor will diagnose asthma through a medical history, including family history, and may also ask if there are certain activities or times that bring on symptoms. A physical examination and possibly a breathing test called spirometry to see how your lungs are functioning may be performed. Other tests may include imaging, blood testing, or allergy testing.
Asthma medications can be broken into two groups, quick-relief (bronchodilators) and long-term control (corticosteroids).
Bronchodilators: These quick-relief medications work immediately to expand the passageways into the lungs to relieve the first signs of asthma symptoms. Depending on your type of asthma, you may be instructed to use your quick-relief inhaler before exercising. You may not use your quick-relief medications daily, so it’s important to check to make sure they are not expired. The classes of quick-relief medications are:
Corticosteroids/Antileukotrienes: These medications that provide long-term control are taken every day to prevent symptoms and asthma attacks. They are prescribed in addition to quick-relief medications when asthma is not well controlled. Your doctor will determine how well your asthma is controlled based on how often you use your quick-relief medication and how often you wake up with asthma symptoms at night. The classes of long-term control medications are:
Using an Inhaler: Most asthma medications are used with an inhaler or a nebulizer. Using these devices correctly is key to getting the full benefit of your medications. Inhalers come in different forms, such as metered-dose, dry powder, and soft mist. You may be given a spacer that attaches to a metered-dose inhaler to help get the full dose of medication. It’s common to be prescribed multiple inhalers and some inhalers can contain more than one medication. Make sure you read the instructions and are educated by your provider or pharmacist to learn how to use each type you are prescribed.
Lung cancer is the deadliest cancer for both men and women. Thankfully, after many years of lung cancer cases being on the rise, the rate is beginning to decline, and people are also living longer after a lung cancer diagnosis. These changes are attributable to the decline of tobacco smoking and earlier identification and treatment.
Risk factors for lung cancer include:
Like many cancers, symptoms can vary and, often, there are no symptoms in earlier stages of lung cancer. Here are some of the symptoms associated with lung cancer (please note that these symptoms could be attributable to many noncancerous conditions as well).
The type of lung cancer determines the method of treatment. Some treatments for lung cancer include chemotherapy, surgery, radiation, or targeted therapy (using specific drugs to block the growth or spread of the cancer). You and your doctor will discuss what treatment is best for you.
Preventive measures for respiratory illnesses:
IMPORTANT NOTE ABOUT ANTIBIOTIC USE FOR RESPIRATORY ILLNESSES: Antibiotics are used to fight infections caused by bacteria. Antibiotics are not generally recommended for respiratory illnesses like bronchitis because these illnesses are typically caused by viruses. Even when bacteria causes the respiratory infection, it is often not advised to take antibiotics, but rather to allow the infection to run its course. Overuse of antibiotics can lead to the presence of bacteria in your body that do not respond to antibiotic treatment (also called “antibiotic-resistant” bacteria). Side effects of antibiotics can range from minor rashes to serious conditions including antibiotic-resistant infections such as c-diff that results in diarrhea and colon damage.
Therapeutic measures that are recommended for a respiratory illness include:
Although, in general, respiratory illnesses will improve on their own, please contact your doctor if you experience:
As noted above, antibiotics are often not advised for treatment of respiratory illnesses. Over-the-counter medications can help manage common symptoms of respiratory illnesses, including stuffy/runny nose, sore throat, and cough.
More than one million people in the United States have died from COVID-19. Most people have mild symptoms, but some people do become severely ill. COVID-19 is spread through droplets from an infected person’s mouth or nose getting into someone’s eyes, nose or mouth; these droplets containing the virus can also be found and transferred from surfaces like doorknobs.
Preventive measures for COVID-19 include:
Symptoms can appear from 2-14 days after exposure and can expand beyond the list provided below, but these are some of the more commonly reported:
Because COVID-19 shares many similar symptoms to other respiratory or gastrointestinal viruses, the only way to confirm it’s COVID is to test. If you test positive, stay home and isolate from others in your home for the first five days; you may need to isolate longer if you have not been fever free for 24 hours or your symptoms aren’t improving.
If you were exposed to COVID-19, the CDC recommends masking for 10 full days after the exposure and testing 6 days after your exposure. Recommendations are to complete the 10 days of masking if you do test negative as you could test positive or develop symptoms after day 6.
Therapeutic measures for COVID-19 include:
