COPD

Chronic Obstructive Pulmonary Disease (COPD) is often a mix of two diseases:

• Chronic bronchitis. In chronic bronchitis, the airways that carry air to the lungs inflamed and make a lot  of mucus. This can narrow or block the airways, making it hard for you to breathe.
• Emphysema. In a healthy person, the tiny air sacs in the lungs are like balloons. As you breathe in and out, they get bigger and smaller to move air through your lungs. But with emphysema, these air sacs are damaged and lose their stretch. Less air gets in and out of the lungs, which makes you feel short of breath.

COPD gets worse over time. You can’t undo the damage to your lungs. But you can take steps to prevent more damage and to feel better.

COPD is almost always caused by smoking. Over time, breathing tobacco smoke irritates the airways and destroys the stretchy fibers in the lungs.

Other things that may put you at risk include breathing chemical fumes, dust, or air pollution over a long period of time. Second hand smoke is also bad.

It usually takes many years for the lung damage to start causing symptoms, so COPD is most common in people who are older than 60.

You may be more likely to get COPD if you had a lot of serious lung infections when you were a child. People who get emphysema in their 30s or 40s may have a disorder that runs in families, called alpha-1 antitrypsin deficiency. But this is rare.

The main symptoms are: a long-lasting cough, shortness of breath that gets worse when you exercise.

As COPD gets worse, you may be short of breath even when you do simple things like get dressed or fix a meal. It gets harder to eat or exercise, and breathing takes much more energy. People often lose weight and get weaker.

The only way to slow COPD is to quit smoking. This is the most important thing you can do. It is never too late to quit. No matter how long you have smoked or how serious your COPD is, quitting smoking can help stop the damage to your lungs.

Your doctor can prescribe treatments that may help you manage your symptoms and feel better.

• Medicines can help you breathe easier. Most of them are inhaled so they go straight to your lungs. If you get an inhaler, it is very important to use it just the way your doctor shows you.
• A lung (pulmonary) rehab program can help you learn to manage your disease. A team of health professionals can provide counseling and teach you how to breathe easier, exercise, and eat well.
• In time, you may need to use oxygen some or most of the time.

People who have COPD are more likely to get lung infections, so you will need to get a flu shot every year. You should also get a pneumonia shot. It may not keep you from getting pneumonia. But if you do get pneumonia, you probably will not be as sick.
