Other genetic factors likely make certain smokers more susceptible to the disease.ĬOPD can cause many complications, including: The uncommon genetic disorder alpha-1-antitrypsin deficiency is the cause of some cases of COPD. In the developing world, people exposed to fumes from burning fuel for cooking and heating in poorly ventilated homes are at higher risk of developing COPD.

Long-term exposure to chemical fumes, vapors and dusts in the workplace can irritate and inflame your lungs.

Occupational exposure to dusts and chemicals.

The combination of asthma and smoking increases the risk of COPD even more. Asthma, a chronic inflammatory airway disease, may be a risk factor for developing COPD. Pipe smokers, cigar smokers and marijuana smokers also may be at risk, as well as people exposed to large amounts of secondhand smoke. The more years you smoke and the more packs you smoke, the greater your risk. The most significant risk factor for COPD is long-term cigarette smoking. In addition, some people can be treated by replacing the missing AAt protein, which may prevent further damage to the lungs. Alpha-1-antitrypsin deficiency can cause liver disease, lung disease or both.įor adults with COPD related to AAt deficiency, treatment options include those used for people with more-common types of COPD. AAt is made in the liver and secreted into the bloodstream to help protect the lungs. In about 1% of people with COPD, the disease results from a genetic disorder that causes low levels of a protein called alpha-1-antitrypsin (AAt). Other irritants can cause COPD, including cigar smoke, secondhand smoke, pipe smoke, air pollution, and workplace exposure to dust, smoke or fumes. But there are likely other factors at play in the development of COPD, such as a genetic susceptibility to the disease, because not all smokers develop COPD. In the vast majority of people with COPD, the lung damage that leads to COPD is caused by long-term cigarette smoking.

You develop a chronic cough trying to clear your airways. In this condition, your bronchial tubes become inflamed and narrowed and your lungs produce more mucus, which can further block the narrowed tubes. Small airways collapse when you exhale, impairing airflow out of your lungs. This lung disease causes destruction of the fragile walls and elastic fibers of the alveoli. People who have bronchitis often cough up thickened mucus, which can be discolored. COPD causes them to lose their elasticity and over-expand, which leaves some air trapped in your lungs when you exhale.īronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. Your lungs rely on the natural elasticity of the bronchial tubes and air sacs to force air out of your body. At the same time, carbon dioxide - a gas that is a waste product of metabolism - is exhaled. The oxygen in the air you inhale passes into these blood vessels and enters your bloodstream.

The air sacs have very thin walls full of tiny blood vessels (capillaries). Inside your lungs, these tubes divide many times - like the branches of a tree - into many smaller tubes (bronchioles) that end in clusters of tiny air sacs (alveoli). How your lungs are affectedĪir travels down your windpipe (trachea) and into your lungs through two large tubes (bronchi). They may be misdiagnosed as having COPD until a more thorough evaluation is performed. Some smokers develop less common lung conditions. Only some chronic smokers develop clinically apparent COPD, although many smokers with long smoking histories may develop reduced lung function. In the developing world, COPD often occurs in people exposed to fumes from burning fuel for cooking and heating in poorly ventilated homes. The main cause of COPD in developed countries is tobacco smoking. Seek immediate medical care if you can't catch your breath, if you experience severe blueness of your lips or fingernail beds (cyanosis) or a rapid heartbeat, or if you feel foggy and have trouble concentrating. Talk to your doctor if your symptoms are not improving with treatment or getting worse, or if you notice symptoms of an infection, such as fever or a change in sputum. People with COPD are also likely to experience episodes called exacerbations, during which their symptoms become worse than the usual day-to-day variation and persist for at least several days. Unintended weight loss (in later stages).A chronic cough that may produce mucus (sputum) that may be clear, white, yellow or greenish.Shortness of breath, especially during physical activities.COPD symptoms often don't appear until significant lung damage has occurred, and they usually worsen over time, particularly if smoking exposure continues.
