Question: What is (are) COPD ?
Answer: Chronic obstructive pulmonary disease, or COPD, is a progressive lung disease in which the airways of the lungs become damaged, making it hard to breathe. You may also have heard COPD called other names, like emphysema or chronic bronchitis. In people who have COPD, the airways that carry air in and out of the lungs are partially blocked, making it difficult to get air in and out. COPD is a major cause of death and illness throughout the world. It kills more than 120,000 Americans each year. That's one death every 4 minutes. How COPD Affects Airways The "airways" are the tubes that carry air in and out of the lungs through the nose and mouth. The airways of the lungs branch out like an upside-down tree. At the end of each branch are many small, balloon-like air sacs. In healthy people, the airways and air sacs are elastic (stretchy). When you breathe in, each air sac fills up with air, like a small balloon, and when you breathe out, the balloon deflates and the air goes out. In people with COPD, the airways and air sacs lose their shape and become floppy. Less air gets in and less air goes out of the airways because - The airways and air sacs lose their elasticity like an old rubber band. - The walls between many of the air sacs are destroyed. - The walls of the airways become thick and inflamed or swollen. - Cells in the airways make more mucus or sputum than usual, which tends to clog the airways.

COPD Develops Slowly, Has No Cure When COPD is severe, shortness of breath and other symptoms of COPD can get in the way of even the most basic tasks, such as doing light housework, taking a walk, even washing and dressing. COPD develops slowly, and it may be many years before you notice symptoms like feeling short of breath. Most of the time, COPD is diagnosed in middle-aged or older people. There is no cure for COPD. The damage to your airways and lungs cannot be reversed, but there are things you can do to control the disabling effects of the disease. COPD is not contagious. You cannot catch it from someone else.

Question: What causes COPD ?
Answer: Smoking Most cases of COPD develop over time, from breathing in fumes and other things that irritate the lungs. Some of the things that put you at risk for COPD include smoking, environmental exposure, and genetic factors. Cigarette smoking is the most common cause of COPD in the United States (either current or former smokers). Pipe, cigar, and other types of tobacco smoking can also cause COPD, especially if the smoke is inhaled. Environmental Exposure COPD can also occur in people who have had long-term exposure to things that can irritate your lungs, like chemical fumes, or dust from the environment or workplace. Heavy or long-term exposure to secondhand smoke or other air pollutants may also contribute to COPD even if you have never smoked or had long-term exposure to harmful pollutants. Secondhand smoke is smoke in the air from other people smoking. Genetic Factors In a small number of people, COPD is caused by a genetic condition known as alpha-1 antitrypsin, or AAT, deficiency. People who have this condition have low levels of alpha-1 antitrypsin (AAT)a protein made in the liver. Having a low level of the AAT protein can lead to lung damage and COPD if you're exposed to smoke or other lung irritants. If you have this condition and smoke, COPD can worsen very quickly. While very few people know if they have AAT deficiency, it is estimated that about 1 in every 1,600 people to about 1 in every 5,000 people have it. People with AAT deficiency can get COPD even if they have never smoked or had long-term exposure to harmful pollutants. Asthma Although uncommon, some people who have asthma can develop COPD. Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. Treatment usually can reverse the inflammation and narrowing. However, if not, COPD can develop.

Question: What are the symptoms of COPD ?
Answer: Common Symptoms The most common symptoms of COPD are - a cough that does not go away - coughing up lots of sputum (mucus). a cough that does not go away coughing up lots of sputum (mucus). These symptoms often start years before the flow of air in and out of the lungs is reduced. Not everyone who has a cough and sputum goes on to develop COPD. Other common symptoms of COPD include - shortness of breath while doing activities you used to be able to do - wheezing (a whistling sound when you breathe) - tightness in the chest. shortness of breath while doing activities you used to be able to do wheezing (a whistling sound when you breathe) tightness in the chest. Getting a Diagnosis Your doctor will diagnose COPD based on your signs and symptoms, your medical and family histories, and test results. If your doctor thinks you may have COPD, he or she will examine you, listen to your lungs, and ask you questions about your medical history, and what lung irritants you may have been around for long periods of time. The Spirometry Test To confirm a diagnosis of COPD, your doctor will use a breathing test called spirometry. The test is easy and painless and shows how much air you can breathe out and measures how fast you can breathe it out. In a spirometry test, you breathe hard into a large hose connected to a machine called a spirometer. When you breathe out, the spirometer measures how much air your lungs can hold and how fast you can blow air out of your lungs. Spirometry can detect COPD before symptoms develop. Your doctor also might use the test results to find out how severe your COPD is and to help set your treatment goals. The test results also may help find out whether another condition, such as asthma or heart failure, is causing your symptoms. Determining COPD Severity Based on this test, your doctor can determine if you have COPD and how severe it is. There are four levels of severity for COPD: - people at risk for COPD - people with mild COPD - people with moderate COPD - people with severe COPD. people at risk for COPD people with mild COPD people with moderate COPD people with severe COPD. People at risk for developing COPD have a normal breathing test and mild symptoms such as chronic cough and sputum (mucus) production. People with mild COPD have mild breathing limitation. Symptoms may include a chronic cough and sputum (mucus) production. At this stage, you may not be aware that airflow in your lungs is reduced. People with moderate COPD have a breathing test that shows worsening airflow blockages. Symptoms may be worse than with mild COPD and you may experience shortness of breath while working hard, walking fast, or doing brisk activity. At this stage, you would seek medical attention. People with severe COPD have a breathing test that shows severe limitation of the airflow. People with severe COPD will be short of breath after just a little activity. In very severe COPD, complications like respiratory failure or signs of heart failure may develop. At this stage, quality of life is impaired and worsening symptoms may be life-threatening. Other Tests Other tests are used to rule out other causes of the symptoms. - Bronchodilator reversibility testing uses the spirometer and medications called bronchodilators to assess whether breathing problems may be caused by asthma. Bronchodilator reversibility testing uses the spirometer and medications called bronchodilators to assess whether breathing problems may be caused by asthma. - A chest X-ray or a chest CT scan may also be ordered by your doctor. These tests create pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. The pictures can show signs of COPD. They also may show whether another condition, such as heart failure, is causing your symptoms. A chest X-ray or a chest CT scan may also be ordered by your doctor. These tests create pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. The pictures can show signs of COPD. They also may show whether another condition, such as heart failure, is causing your symptoms. - An arterial blood gas test is another test that is used. This blood test shows the oxygen level in the blood to see how severe your COPD is and whether you need oxygen therapy. An arterial blood gas test is another test that is used.

Question: What causes COPD ?
Answer: COPD is a disease that slowly worsens over time, especially if you continue to smoke. If you have COPD, you are more likely to have lung infections, which can be fatal. If the lungs are severely damaged, the heart may be affected. A person with COPD dies when the lungs and heart are unable to function and get oxygen to the body's organs and tissues, or when a complication, such as a severe infection, occurs. Treatment for COPD may help prevent complications, prolong life, and improve a person's quality of life.

Question: What causes COPD ?
Answer: Cigarette smoking is the most common cause of COPD. Most people with COPD are smokers or have been smokers in the past. Breathing in other fumes and dusts over long periods of time can also lead to COPD. Pipe, cigar, and other types of tobacco smoking can cause COPD, especially if the smoke is inhaled. Exposure to secondhand smoke can play a role in causing COPD. Most people with COPD are at least 40 years old or around middle age when symptoms start.

Question: How to diagnose COPD ?
Answer: If you have not been exercising regularly, you should get the advice of your doctor before starting. The symptoms of COPD are different for each person. People with mild COPD may not have much difficulty walking or exercising. As the symptoms of COPD get worse over time, a person may have more difficulty with walking and exercising. You should talk to your doctor about exercising and whether you would benefit from a pulmonary or lung rehabilitation program.

Question: How to prevent COPD ?
Answer: If you smoke, the most important thing you can do to prevent more lung damage is to stop smoking. It is also important to stay away from people who smoke and places where you know there will be smokers. Avoid exposure to pollutants like dust, fumes, and poor air quality, and take precautions to prevent flu and pneumonia. Following your doctor's instructions with medications and rehabilitative treatment can help alleviate COPD symptoms and control the disabling effects of the disease.

Question: What are the treatments for COPD ?
Answer: Bronchodilators and inhaled steroids are two medications used to treat COPD. Bronchodilators work by relaxing the muscles around the airways, opening them and making it easier to breathe. People with mild COPD take bronchodilators using an inhaler only when needed. Those with moderate or severe COPD may need more regular treatment. Inhaled steroids also are used for people with moderate or severe COPD in order to reduce swelling in the airways.

Question: What are the symptoms of COPD ?
Answer: Call your doctor right away if your symptoms worsen suddenly. People with COPD may have symptoms that suddenly get worse. When this happens, you have a much harder time catching your breath. Symptoms that worsen suddenly can include sudden chest tightness, more coughing, a change in your sputum (mucus), or fever. Your doctor will look at things that may be causing these sudden symptoms. Sometimes the symptoms are caused by a lung infection.
