COPD can cause your lungs to produce excess mucus, leading to frequent coughing. Not all coughs are effective in clearing excess mucus from the lungs. Explosive or uncontrolled coughing causes airways to collapse and spasm, trapping mucus.
Cough and mucus production (phlegm) are common reasons for people with COPD to seek medical care, yet COPD-associated cough and phlegm have few effective therapies compared to other common symptoms, such as dyspnea.
1) Signs and symptoms of COPD
The colour of your spit or phlegm may change from frothy and white to slightly yellow or green if you have a chest infection.
Stage 1 Symptoms are mild and often unnoticed, except during times of exertion. These include mild shortness of breath and a nagging dry cough. Stage 2 Shortness of breath worsens, accompanied by a persistent cough and phlegm production. Flare-ups can cause changes in phlegm color.
Guaifenesin: Guaifenesin is the most commonly used expectorant. It is the active ingredient in medicines including Mucinex® and Robitussin®. You can find guaifenesin in many common cough, cold and flu medications.
So what is the normal oxygen level? People who are breathing normal, who have relatively healthy lungs (or asthma that is under control), will have a blood oxygen level of 95% to 100%. Anything between 92% and 88%, is still considered safe and average for someone with moderate to severe COPD.
The exact length of time you can live with COPD depends on your age, health, and symptoms. Especially if your COPD is diagnosed early, if you have mild stage COPD, and your disease is well managed and controlled, you may be able to live for 10 or even 20 years after diagnosis.
There are four distinct stages of COPD: mild, moderate, severe, and very severe. Your physician will determine your stage based on results from a breathing test called a spirometry, which assesses lung function by measuring how much air you can breathe in and out and how quickly and easily you can exhale.
In general, COPD progresses gradually — symptoms first present as mild to moderate and slowly worsen over time. Often, patients live with mild COPD for several decades before the disease progresses to moderate or severe.
When COPD gets worse it is called an exacerbation (ex-zass-er-BAY-shun). During an exacerbation you may suddenly feel short of breath, or your cough may get worse. You may also cough up phlegm, and it may be thicker than normal or an unusual color.
Chest x-ray: This exam can help support the diagnosis of COPD by producing images of the lungs to evaluate symptoms of shortness of breath or chronic cough. While a chest x-ray may not show COPD until it is severe, the images may show enlarged lungs, air pockets (bullae) or a flattened diaphragm.
Mucus can tell quite the health story. Too much mucus is a sign of a chronic respiratory condition, acute illness, and some types of chronic obstructive pulmonary disease (COPD). 1 While mucus can be beneficial to the body, producing too much mucus can cause breathing difficulties and infection.
Things like allergies, eating spicy food, and being outside in the cold can result in a more watery nasal leakage. Your body usually makes thicker mucus when you have a cold (caused by viruses) or sinus infection (caused by bacteria). Most mucus problems are temporary.
Although COPD is terminal, people may not always die of the condition directly, or of oxygen deprivation. Some people with COPD have other medical conditions, particularly cardiovascular disease. In fact, within 5 years of diagnosis, COPD is also an independent risk factor for sudden cardiac death.
Although any damage done to your lungs and airways cannot be reversed, giving up smoking can help prevent further damage. This may be all the treatment that's needed in the early stages of COPD, but it's never too late to stop – even people with more advanced COPD will benefit from quitting.
Stage 1: Mild COPD
"During mild stage COPD, you may feel out of breath during light physical activity, like doing housework or walking up the stairs," says Dr. Hatipoglu. "A hacking cough that produces mucus is also common," he adds.
Airflow obstruction is associated with increased mortality, even with mild impairment. In mild to moderate COPD, most deaths are due to cardiovascular disease and lung cancer, but as COPD severity increases, respiratory deaths are increasingly common.
COPD has no cure yet, but this doesn't mean that it's untreatable. By improving your lifestyle, you can live a long and full life with COPD. A common misinterpretation is that 'Chronic' means really bad or extreme rather than long term.
Rizzo, MD, chief medical officer for the American Lung Association. "It's not a death sentence by any means. Many people will live into their 70s, 80s, or 90s with COPD.” But that's more likely, he says, if your case is mild and you don't have other health problems like heart disease or diabetes.
Shortness of breath does not always indicate that you are hypoxic. In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
Stage IV: Very Severe
You doctor may prescribe supplemental oxygen to help with your breathing.
Stage 2 (moderate) COPD: You may experience persistent coughing and phlegm (often worse in the morning), increased shortness of breath, tiredness, sleep problems, or wheezing. About one in five people have exacerbations that worsen their symptoms and cause the color of their phlegm to change.
