Asthma/Respiratory

Asthma

Asthma is a condition lung disease that makes it hard to breathe. During an asthma attack (also called an asthma exacerbation), the airways become narrow, making breathing difficult. Asthma attacks can vary in severity. Symptoms of an attack may include coughing, wheezing, or chest tightness. There is no cure for asthma, but it can be managed through proper medication and by avoiding things that trigger your asthma.

An asthma attack usually begins with exposure to a "trigger," which is exposure to something (usually an external allergen or irritant) that causes the airways to react. Asthma triggers vary from person to person. Some common triggers include
  • dust mites
  • pollen
  • strong fragrances
  • chemicals (e.g., household cleaning products)
  • secondhand smoke
  • mold
  • air pollution and smoke
  • strenuous exercise
  • strong emotion
  • stress
  • pets
  • cockroaches

COPD

Chronic obstructive pulmonary disease (COPD) refers to a group of lung diseases that cause reduced airflow in the lungs, making it difficult to breathe. The most common lung conditions that make up COPD are emphysema and chronic bronchitis. Symptoms include coughing, shortness of breath, chest tightness, and wheezing. COPD is a progressive disease, which means that it gets worse over time. COPD also has no cure. For this reason, COPD can result in major long-term disability and can limit an individual's ability to perform routine activities. People who have COPD have a higher risk of getting respiratory infections such as colds, pneumonia, and the flu.

Asthma

The CDC National Asthma Control Program reports that 1 in 12 children and adults have asthma. Based on the most recent data available, there were 2.0 million emergency department visits and 3,615 deaths due to asthma across the U.S. in 2014.

Since there is no cure for asthma, it is a health burden that stays with people for their whole lives. This translates into lifelong costs for medication and treatment, as there are many direct and indirect economic costs associated with asthma. The CDC reports asthma costs Americans about $56 billion per year. In Utah, it is estimated that asthma-related emergency department visits and hospitalizations cost $27.6 million in 2013. For a complete report on the costs of asthma in Utah, please see the Financial Burden of Asthma in Utah report.

COPD

COPD plays a large role in death and disability in the United States; in 2014, it was the third leading cause of death. Approximately 15.7 million Americans have been diagnosed with COPD. COPD cannot be cured and it gets progressively worse over time, resulting in major long-term disability. Treatment is necessary in order to reduce the symptoms and help slow down its progression. This can include medicine, surgery, and oxygen therapy. COPD can also lead to other health issues such as heart disease, lung cancer, and high blood pressure.

Asthma

Three things happen during an asthma attack that make it hard to breathe:
  1. The lining of the airways (bronchial tubes) become inflamed and swollen.
  2. The muscles around the airway tighten.
  3. Excess mucus is produced.

When this happens, the airways become narrow, making it hard to breathe. Symptoms of an asthma attack may include chest tightness, wheezing, shortness of breath, or coughing. Signs of an asthma emergency include: retractions (sucking in of the skin against the collarbone or ribs); the face becoming a pale gray or blue color; darkening of lips or fingernails to a purple or blue color; and struggling to talk.

COPD

To understand COPD, it helps to understand how the lungs work. When you breathe, oxygen enters the bloodstream through small air sacs (called alveoli) at the end of the airways in the lungs. At the same time, waste gasses like carbon dioxide leave the blood and are exhaled. Normally, the air sacs are elastic (or stretchy), and inflate and deflate like balloons during breathing. In COPD, less air flows through the airways due to one or more of the following:
  • The airways and sacs lose some of their elasticity
  • The walls between many of the air sacs are destroyed
  • The airways make more mucus than usual, which can clog them
  • The walls of the airways become thick and inflamed

In emphysema, the walls between many of the air sacs are damaged, causing them to lose shape and become floppy. The walls of the air sacs can also be destroyed, leading to fewer, larger sacs that reduce the amount of air that is exchanged.

In chronic bronchitis, the lining of the airways is constantly inflamed and irritated, causing it to thicken. Large quantities of thick mucus also form in the airways, making it hard to breathe.

Asthma

There are many factors that influence the risk of developing asthma. The CDC reports that risk is increased in the following areas:
  • Sex: Males are more likely to have asthma in children. However, for adults, females are more likely to have asthma.
  • Age: Young adults ages 18-24 are more likely to have asthma when compared with older adults.
  • Race and ethnicity: Black children are twice as likely to have asthma than White children. Multiracial and Black adults have a higher risk than White adults. Asthma attacks have decreased in children of all races since 2001.
  • Education: Adults who did not graduate high school have a higher risk than adults who did graduate high school or college.
  • Income: People with incomes below $75,000 per year are more likely to have asthma than those who have greater incomes.
  • Behavior: Smoking increases the risk of asthma as does obesity.

COPD

Risk factors for COPD include the following:
  • Smoking: Tobacco smoke is the greatest risk factor in developing COPD. The best way to prevent COPD is to not smoke or to stop smoking if you already do so.
  • Secondhand smoke: Secondhand smoke is the smoke that comes from someone else's burning and smoking of tobacco products. Secondhand smoke can also increase the risk of COPD.
  • Asthma: People with asthma, or who have had asthma, may have an increased risk of developing COPD.
  • Genetics: Some people may have a rare genetic mutation called alpha-1-antitrypsin deficiency, which may cause COPD.
  • Workplace exposure: People who work in certain settings may be exposed more frequently to chemicals, dust, or other irritants that can harm the lungs.

Asthma

Although there is no cure, it is possible to reduce the risk of severe complications, hospitalizations, and death caused by asthma by properly taking prescribed medication and knowing possible triggers. When you know what triggers your asthma, you can take preventive action to avoid them, and prevent asthma attacks.

Once you are diagnosed with asthma, your healthcare provider will advise you on proper management. Asthma can usually be managed in an outpatient setting, reducing the need for emergency department visits. Effective management includes control of exposures to factors that trigger exacerbations, using medicine as prescribed, monitoring the disease, and patient education in asthma care.

People who work in school-based health centers may be able to help children manage their asthma. This includes helping reduce exposures to environmental asthma triggers, education, case management, improving indoor air quality, improving students' home environments, and improving outdoor air quality around the school and community. The Public Health Insitiute developed a guide for school-based health centers. For more information see the Asthma Environmental Intervention Guide for School-Based Health Centers.

COPD

There are many things you can do to prevent COPD:
  • The best way to prevent COPD is to quit smoking. Even if you have already been diagnosed with COPD, quitting smoking can improve symptoms and possibly avoid worse complications.
  • Avoid secondhand smoke.
  • Avoid other air pollutants and irritants. Use personal protective gear at work to limit your exposure to lung irritants and chemicals.
  • Prevent and treat lung infections. Certain vaccines, like the flu vaccine and pneumonia immunizations, are important in preventing chronic lung infections. Current respiratory infections should be treated with antibiotics if possible.

If COPD can be caught and diagnosed early, treatment can begin earlier before progression worsens.

Asthma

Data regarding asthma hospitalizations and emergency department visits come from the Office of Health Care Statistics in the Utah Department of Health. Asthma prevalence data comes from the Utah Behavioral Risk Factor Surveillance System (BRFSS) survey. Asthma management data comes from the Asthma Call-Back Survey (ACBS). The BRFSS and ACBS are conducted by the Survey Center in the Office of Public Health Assessment.
