COPD is serious, chronic, and life-threatening disease, but it doesn't always look that way. Many people with COPD don't appear to be as sick as they are, and the worst aspects of the disease are not always visible on the outside.

COPD and other respiratory diseases often come with health complications, both big and small. One of the more serious complications of COPD is acute respiratory failure, a medical emergency that occurs when you experience a sudden and serious drop in lung function.

Daily medications are a primary life-line for people with COPD, and a necessary part of life for people with asthma and other respiratory diseases. In fact, most COPD patients have to follow a strict treatment regimen and take several different medications every day just to keep their symptoms under control.

If you or someone you love has COPD, then you might have heard about a treatment known as pulmonary rehabilitation. This treatment is essentially a breathing and exercise training program specifically designed for people with COPD and other respiratory problems that make it difficult to breathe.

Consider this hypothetical scenario: you have a COPD exacerbation and your shortness of breath suddenly gets much worse than usual. You call your doctor to see what you should do, and she tells you to go to the hospital right away.

If you are like most people with COPD, you've probably experienced at least some degree of pain in your chest and ribs. This kind of pain can come in a variety of forms, including muscle aches, rib soreness, chest tightness, and general feelings of discomfort.

If you have COPD, your number one responsibility as a patient is to do what your doctor says and take all your medications as prescribed. This might sound simple on the surface but, in reality, it's much easier said than done.
