What is COPD?

Chronic obstructive pulmonary disease, commonly referred to as COPD, is a group of progressive lung diseases.


The most common of these diseases are emphysema which slowly destroys air sacs in your lungs, and interferes with outward air flow and chronic bronchitis which causes inflammation and narrows the bronchial tubes allowing excess mucus to build up. Many people with COPD have both of these conditions, and when it is severe enough, they require supplemental oxygen therapy. To treat cases of COPD, people will opt to use portable oxygen concentrators




It’s estimated that about 30 million people in the United States have COPD, while an estimated 14 million are unaware that they have it. If your COPD goes untreated, it can lead to a faster progression of disease, heart problems, and worsening respiratory infections. 

COPD and Smoking 




Smoking is one of the main causes of COPD, however it is not the only reason people develop this disease. 


In today’s day and age, smoking has a negative connotation, and it is widely known that smoking is bad for your health and the ones around you. This scientific fact has only come to light and into popularity in relatively recent years


There was a time when many of us were alive where smoking was a normal everyday thing that most adults participated in, and the negative effects smoking presented to the smoker and those subjected to secondhand smoke were less known and much less talked about.




Now there are a lot more alternatives for smoking for people who want to quit, there are scientific studies proving the harmful aspects smoking has on your body, there are advertisements and movements to help inform people, and smoking is not allowed indoors and even in private outdoor spaces in most areas. 



The overall language surrounding smoking has changed dramatically, and a lot of the time there is little sympathy for smokers. 


While smoking is a very harsh addiction, there are a lot of tools including therapy that can help you quit. It is much easier said than done, and we do have a few resources on our website that can help smokers nick the habit:

There are a number of other reasons people get COPD later in life, and it's not due to smoking cigarettes. For these people it is important to understand the other reason someone can develop this chronic disease. 

Non-Smokers Who Develop COPD




The most important issue with non-smokers who have COPD is the diagnosis, or lack thereof.


Studies have shown that while COPD symptoms between smokers and non-smokers who have COPD are the same, but in nonsmoking groups the symptoms are less severe. 


Signs of COPD are only present when there has already been significant lung damage caused by the disease. Patients go to their doctors complaining about shortness of breath affecting their normal everyday lives, and then and there, they are tested for COPD

If someone who has never smoked starts to feel the symptoms associated with COPD they may be less likely to think they have lung damage, and could avoid going to the doctor because they have done nothing in their life that would lead to a pulmonary disease. 


If you have one or several of the following COPD symptoms, seek medical attention immediately:


  1. Shortness of Breath

COPD causes dyspnea, and this is usually the first symptoms people notice, which is why it can sometimes be overlooked. People experience dyspnea in many different ways, it is most commonly described by COPD patients as “feeling like gasping or labored breathing.




When your COPD first starts, shortness of breath might only show up when you exercise or exert yourself more than usual, but as your condition progresses, breathlessness will worsen and you will notice it after activities that weren’t tiring before, such as walking.


When the disease progresses people start to realize they are short of breath from the smallest activities. This is when a lot of COPD patients will seek medical attention.



  1. Chronic Cough

A chronic cough, chronic means it gets worse over time, and medically, it’s defined as a cough that lasts for longer than 8-weeks, is another familiar symptom of COPD. This cough you experience is a result of swelling and inflammation taking place in your airways. Next to dyspnea, coughing is one of the first symptoms you’ll notice, and unfortunately it is often overlooked, especially in smokers because they are summed up to a cough from smoking. 




It is common for smokers to chalk it up to being a “smoker’s cough,” allergies, or their environment.

  1. Coughing Up Phlegm

COPD causes increased mucus production, and you’ll be constantly trying to clear your throat because there is excess mucus in your lungs. You might also develop a cough that brings up mucus, it can be a white, yellow, clear, or even greenish in color.




Your body produces mucus to trap inhaled irritants, and therefore smokers will have more mucus production in their body than the average person.

Other COPD symptoms:

  • Wheezing

  • Chest Tightness

  • Unintentional Weight Loss

  • Headaches

Other Causes of COPD Besides Smoking

So what else causes COPD, if you have never smoked before, and haven’t been around second hand smoke much, what could have caused this disease? 



If you are exposed to long-term air pollution it is very possible to develop COPD. 


COPD can also develop from inhaling dust or the fumes of fuel burned for cooking or heating purposes.


COPD can also be caused by chemicals or fumes found in harsh workplace environments.



It is true that COPD has a strong genetic component. As many as 5 percent of people with COPD have a genetic condition known as alpha-1 antitrypsin deficiency, a protein that helps protect the lungs from damage. 




People with COPD have too little alpha-1 antitrypsin by causing your lungs to deteriorate, this condition also affects your liver.
