Interstitial Lung Diseases

Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. The inflammation and scarring make it hard to get enough oxygen. The scarring is called pulmonary fibrosis.

Breathing in dust or other particles in the air is responsible for some types of interstitial lung diseases. Specific types include:

  • Black lung disease among coal miners, from inhaling coal dust
  • Farmer's lung, from inhaling farm dust
  • Asbestosis, from inhaling asbestos fibers
  • Siderosis, from inhaling iron from mines or welding fumes
  • Silicosis, from inhaling silica dust

Other causes include autoimmune diseases or occupational exposures to molds, gases, or fumes. Some types of interstitial lung disease have no known cause.

Treatment depends on the type of exposure and the stage of the disease. It may involve medicines, oxygen therapy, or a lung transplant in severe cases.

Occupational Health

Occupational health problems occur at work or because of the kind of work you do. These problems can include:

  • Cuts, fractures (broken bones), and sprains and strains
  • Loss of limbs
  • Repetitive motion disorders
  • Hearing problems caused by exposure to noise
  • Vision problems
  • Illness caused by breathing, touching, or swallowing unsafe substances
  • Illness caused by exposure to radiation
  • Exposure to germs in health care settings

Good job safety and prevention practices can reduce your risk of these problems. Try to stay fit, reduce stress, set up your work area properly, and use the right equipment and gear.

Ozone

Ozone is a gas. It can be good or bad, depending on where it is. "Good" ozone occurs naturally about 10 to 30 miles above the Earth's surface. It shields us from the sun's ultraviolet rays. Part of the good ozone layer is gone. Man-made chemicals have destroyed it. Without enough good ozone, people may get too much ultraviolet radiation. This may increase the risk of skin cancer, cataracts, and immune system problems.

"Bad" ozone is at ground level. It forms when pollutants from cars, factories, and other sources react chemically with sunlight. It is the main ingredient in smog. It is usually worst in the summer. Breathing bad ozone can be harmful. It can cause coughing, throat irritation, worsening of asthma, bronchitis, and emphysema. It can lead to permanent lung damage, if you are regularly exposed to it.

Pulmonary Rehabilitation

What is pulmonary rehabilitation?

Pulmonary rehabilitation, also known as pulmonary rehab or PR, is a program for people who have chronic (ongoing) breathing problems. It can help improve your ability to function and quality of life. PR does not replace your medical treatment. Instead, you use them together.

PR is often an outpatient program that you do in a hospital or clinic. Some people have PR in their homes. You work with a team of health care providers to find ways to lessen your symptoms, increase your ability to exercise, and make it easier to do your daily activities.

Who needs pulmonary rehabilitation?

Your health care provider may recommend pulmonary rehabilitation (PR) if you have a chronic lung disease or another condition that makes it hard for you to breathe and limits your activities. For example, PR may help you if you:

  • Have COPD (chronic obstructive pulmonary disease). The two main types are emphysema and chronic bronchitis. In COPD, your airways (tubes that carry air in and out of your lungs) are partially blocked. This makes it hard to get air in and out.
  • Have an interstitial lung disease such as sarcoidosis and pulmonary fibrosis. These diseases cause scarring of the lungs over time. This makes it hard to get enough oxygen.
  • Have cystic fibrosis (CF). CF is an inherited disease that causes thick, sticky mucus to collect in the lungs and block the airways.
  • Need lung surgery. You may have PR before and after lung surgery to help you prepare for and recover from the surgery.
  • Have a muscle-wasting disorder that affects the muscles used for breathing. An example is muscular dystrophy.

PR works best if you start it before your disease is severe. However, even people who have advanced lung disease can benefit from PR.

What does pulmonary rehabilitation include?

When you first start pulmonary rehabilitation (PR), your team of health care providers will want to learn more about your health. You will have lung function, exercise, and possibly blood tests. Your team will go over your medical history and current treatments. They may check on your mental health and ask about your diet. Then they will work together to create a plan that is right for you. It may include:

  • Exercise training. Your team will come up with an exercise plan to improve your endurance and muscle strength. You will likely have exercises for both your arms and legs. You might use a treadmill, stationary bike, or weights. You may need to start slowly and increase your exercise as you get stronger.
  • Nutritional counseling. Being either overweight or underweight can affect your breathing. A nutritious eating plan can help you work towards a healthy weight.
  • Education about your disease and how to manage it. This includes learning how to avoid situations that make your symptoms worse, how to avoid infections, and how/when to take your medicines.
  • Techniques you can use to save your energy. Your team may teach you easier ways to do daily tasks. For example, you may learn ways to avoid reaching, lifting, or bending. Those movements make it harder to breathe, since they use up energy and make you tighten your abdominal muscles. You may also learn how to better deal with stress, since stress can also take up energy and affect your breathing.
  • Breathing strategies. You will learn techniques to improve your breathing. These techniques may increase your oxygen levels, decrease how often you take breaths, and keep your airways open longer.
  • Psychological counseling and/or group support. It can feel scary to have trouble breathing. If you have a chronic lung disease, you are more likely to have depression, anxiety, or other emotional problems. Many PR programs include counseling and/or support groups. If not, your PR team may be able to refer you to an organization that offers them.

Smoking

What are the health effects of smoking?

There's no way around it; smoking is bad for your health. It harms nearly every organ of the body, even some that you would not expect. Cigarette smoking causes many cancers and other health problems. It is also the cause of nearly one in five deaths in the United States.

Some of the many health problems that smoking can cause include:

  • Cancers. Smoking is the most common cause of lung and oral cancers. But it can also cause cancer in many other parts of your body, such as in your larynx (voice box), esophagus, throat, bladder, kidney, liver, stomach, pancreas, colon and rectum, and cervix. It can also cause acute myeloid leukemia (AML).
  • Lung diseases. Smoking is the most common cause of COPD. It can also worsen asthma and raise your risk of pneumonia.
  • Cardiovascular diseases. Smoking can damage your blood vessels and make them thicken and grow narrower. This makes your heart beat faster and raises your blood pressure. Smoking also increases your risk of blood clots and stroke.
  • Vision problems. Smoking can raise your risk of cataracts and cause macular degeneration (AMD).

You have a greater chance of certain pregnancy problems if you smoke while pregnant. Your baby is also at higher risk of dying of sudden infant death syndrome (SIDS).

Smoking also causes addiction to nicotine, a stimulant drug that is in tobacco. Nicotine addiction makes it much harder for people to quit smoking.

What are the health risks of secondhand smoke?

Your smoke is also bad for other people. If they breathe in your secondhand smoke, they can get many of the same problems as smokers do. These problems can include heart disease and lung cancer. Children exposed to secondhand smoke have a higher risk of ear infections, colds, pneumonia, bronchitis, and more severe asthma. If you breathe secondhand smoke while pregnant, you're more likely to have preterm labor and a baby with low birth weight.

Are other forms of tobacco also dangerous?

Besides cigarettes, there are several other forms of tobacco. Some people smoke tobacco in cigars and water pipes (hookahs). These forms of tobacco also contain harmful chemicals and nicotine. Some cigars contain as much tobacco as an entire pack of cigarettes.

E-cigarettes often look like cigarettes, but they work differently. They are battery-operated smoking devices. Using an e-cigarette is called vaping. Researchers still have a lot to learn about the health effects of using e-cigarettes. We do know that they contain nicotine, which is highly addictive and a health danger to you and your fetus if you are pregnant, children, and teens. And e-cigarettes also expose non-smokers to secondhand aerosols (rather than secondhand smoke), which contain harmful chemicals.

Smokeless tobacco, such as chewing tobacco and snuff, is also bad for your health. Smokeless tobacco can cause certain cancers, including oral cancer. It also increases your risk of getting heart disease, gum disease, and oral lesions.

Why should I quit?

Remember, there is no safe level of tobacco use. Smoking even just one cigarette per day over a lifetime can cause smoking-related cancers and premature death. Quitting smoking can reduce your risk of health problems and add years to your life. The earlier you quit, the greater the benefit. Some immediate benefits of quitting include:

  • Lower heart rate and blood pressure
  • Less carbon monoxide in the blood (carbon monoxide reduces the blood's ability to carry oxygen)
  • Better circulation
  • Less coughing and wheezing

Quitting smoking can be challenging, but it is so important for your health. Contact your health care provider if you need help quitting.
