Millions of people in the United States and worldwide have It causes breathing difficulty and discomfort. There are two causes of COPD: chronic bronchitis and emphysema. While asthma is not typically considered one of the conditions classified as COPD, some people may have both. You may have COPD if you notice persistent, prolonged changes to your breathing. Symptoms include: • tightness in your chest • difficulty taking deep breaths • wheezing • feeling out of breath • coughing • feeling tired • frequent colds and infections in your nose and throat These symptoms will get worse over time if you don’t seek treatment. You can also develop conditions like irregular heartbeats, heart failure, and high blood pressure if you don’t get COPD diagnosed and treated. Two conditions cause COPD: chronic bronchitis and emphysema. Both affect your lungs in different ways. Asthma is not typically considered a type of COPD, but it is a chronic respiratory condition. You can have asthma along with COPD. Chronic bronchitis Emphysema Emphysema causes damage to the alveoli. These are your lungs’ air sacs. The damage destroys the walls of the alveoli. There are It also stretches out your lungs. This makes it more difficult to breathe because air gets trapped in them. This damage cannot be reversed. Asthma It can lead to more problematic respiratory symptoms, affect your quality of life, and increase the chances of hospitalization. Both types of COPD can occur for the same reasons.

What Is COPD? Types of COPD Emphysema. This results from damage to your lungs’ air sacs (alveoli) that destroys the walls inside them and causes them to merge into one giant air sac. It can’t absorb oxygen as well, so you get less oxygen in your Chronic bronchitis. If you have Refractory asthma. This type may also be called nonreversible. It doesn’t respond to normal COPD Causes and Risk Factors Long-term exposure to things that irritate your lungs is the most common cause. In the U.S., that’s cigarette, pipe, or other types of Your age can make COPD more likely. It develops slowly over the years, so most people are at least 40 when symptoms begin. It’s rare, but your genes could put you at risk for COPD. If you lack a protein called alpha 1 antitrypsin ( What Are the Symptoms? At first, you might not have any symptoms. But as the disease gets worse, you might notice these common signs of COPD: • A cough that doesn't go away • Coughing up lots of mucus • Shortness of breath, especially when you’re physically active • • Tightness in your chest • Frequent • Blue fingernails • Low energy • Losing weight without trying (in later stages) • COPD Diagnosis and Tests Your doctor will ask about your symptoms, your medical history, and whether you smoke or have been exposed to chemicals, dust, or smoke at work. They’ll also do a The most common test is called Your doctor may order other tests to rule out other • More lung function tests • Chest X-rays that can help rule out emphysem...

What is chronic obstructive pulmonary disease (COPD)? COPD is a term that refers to a group of lung diseases that can interfere with normal breathing. According to the American Lung Association, more than 13 million Americans suffer from COPD. It is the third leading cause of death in the U.S. What are the different types of COPD? The two most common conditions of COPD are chronic bronchitis and emphysema. Some doctors agree that asthma should be classified as a chronic obstructive pulmonary disease, while others do not. A brief description of asthma is included below: What is chronic bronchitis? Chronic bronchitis means long-term inflammation of the bronchi (the breathing passages in the lungs), which results in increased production of mucus, as well as other changes. These changes may result in breathing problems, frequent infections, cough, and disability. What is pulmonary emphysema? Emphysema is a chronic lung condition in which alveoli (the air sacs in the lungs) may become: • Destroyed • Narrowed • Collapsed • Stretched • Overinflated This can cause a decrease in respiratory function and breathlessness. Damage to the air sacs is irreversible and results in permanent "holes" in the lung tissue. What is asthma? Asthma is a chronic, inflammatory lung disease involving recurrent breathing problems. The characteristics of asthma include the following: • The lining of the airways becomes swollen and inflamed. • The muscles that surround the airways tighten. • The producti...

Chronic obstructive pulmonary disease, commonly referred to as COPD, is a group of progressive lung diseases. The most common of these diseases are Emphysema slowly destroys air sacs in your lungs, which interferes with outward air flow. Bronchitis causes inflammation and narrowing of the bronchial tubes, which allows mucus to build up. It’s estimated that about Untreated, COPD can lead to a faster progression of disease, heart problems, and worsening respiratory infections. COPD makes it harder to breathe. Symptoms may be mild at first, beginning with intermittent coughing and shortness of breath. As it progresses, symptoms can become more constant to where it can become increasingly difficult to breathe. You may experience wheezing and tightness in the chest or have excess sputum 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: • occasional shortness of breath, especially after exercise • mild but recurrent cough • needing to clear your throat often, especially first thing in the morning You might start making subtle changes, such as avoiding stairs and skipping physical activities. Worsening symptoms Symptoms can get progressively worse and harder to ignore. As the lungs become more damaged, you may experience: • shortness of breath, after even mild forms of exercise like walking up a flight of stairs ...

The system looks at many things. The basic idea is to understand how severe your What Is the GOLD System for Grading COPD? The GOLD system bases the stage of your COPD on several things: • Your symptoms • How many times your COPD has gotten worse • Any times you’ve had to stay in the hospital because your COPD has gotten worse • Results from spirometry, a test that checks the amount of air and speed that you can exhale GOLD stands for the Global Initiative for Chronic Obstructive Lung Disease. The National Heart, Lung, and Blood Institute, National Institutes of Health, and the World Health Organization started it in 1997. GOLD helps raise awareness of COPD and works with doctors and other health experts to create better ways to prevent and treat this condition. It also creates the guidelines most doctors use to classify and treat COPD. Spirometry and Your COPD Stage Spirometry results are based on two measurements: • Forced vital capacity (FVC). This is the largest amount of air you can • Forced expiratory volume (FEV-1). FEV-1 shows how much air you can exhale from your GOLD Stages or Grades The original GOLD system used the term "stages" to refer to the different levels of COPD. Now they’re called "grades." Experts believe this new system allows doctors to better match patients with the right treatments. The original stages also relied only on FEV results. But now doctors consider other things, too. Your doctor will assign grades to these four things: • How severe your ...
