How to Know if Your COPD is Getting Worse
Living with a chronic lung disease like COPD means dealing with a lot of uncertainty. This includes small, everyday uncertainties (like “will my symptoms act up today?”) and broader unknowns about the long-term future of your health.
These uncertainties are amplified by the fact that COPD is progressive, which means that the disease inevitably gets worse over time. COPD patients have to live with the knowledge that their condition will worsen without knowing when or how it will happen, or what additional complications might eventually arise.
This is further complicated by the fact that COPD is, well... complicated. Every case of COPD is different, making it difficult to predict a patient's future outcomes or get an accurate timeline for the course of their disease.
What's more, COPD symptoms tend to fluctuate frequently, often without any obvious warning or explanation. This makes it difficult for many COPD patients to interpret their symptoms, which can cause a great deal of anxiety anytime those symptoms change.
That's why we created this guide to answer the the oft-asked question, “Is my COPD getting worse?” We'll start by exploring COPD progression, including how it works and what it looks like. Then we'll show you how to tell the difference between permanent COPD progression and the kinds of temporary symptom flare-ups that affect all COPD patients, even those with “stable” COPD.
Next, we'll walk you through a series of questions and real-life scenarios that can help you evaluate the progression of your own (or a loved one's) COPD. Then, we'll send you off with some practical tips to help you take a more active role in monitoring and managing your disease.
By the end of this guide, you'll know how to spot the signs of COPD progression and how to work with your doctor to get the best possible outcomes for your disease. But before we get too far ahead, let's take a moment to examine some key dynamics COPD progression, including how it happens, why it happens, and what you can (and cannot) do to slow it down.
COPD Progression: The Unfortunate Reality of Living With COPD
COPD progression is a fact of life for COPD patients, and this naturally causes a great deal of anxiety for many people with COPD. A major source of that anxiety is uncertainty about the future—the sense of not knowing when and how the disease will worsen, or how you will deal with those changes when they come.
And while it's not possible to get rid of that uncertainty entirely, knowledge can be a powerful mitigating force. The more you learn about COPD progression, the more prepared you'll be when it happens, and less scary and unfamiliar the future will seem.
In the following sections, we're going to take a closer look what COPD progression looks like and what causes COPD symptoms to get worse over time. We'll also look at some of the ways doctors and researchers predict future COPD progression, and how certain symptoms and risk factors are linked to slower or faster progression in people with the disease.
How COPD Progression is Measured: The 4 Main Stages of COPD
Doctors have a variety of ways to measure how severe a person's COPD is and, thus, how far the disease has progressed. Methods include tracking patients' symptoms, analyzing data from lung function tests, and using other data (e.g. symptoms, exacerbations, and medical imaging) to estimate the severity of the disease.
The most common method for determining COPD progression is known as “staging” or “grading,” which is a standardized technique for ranking the severity of COPD on a scale from 1-4. The most widely-used staging guidelines (known as the GOLD Criteria) allow doctors to quickly judge a person's COPD stage based primarily on the results of simple lung function tests.
In general, COPD symptoms get more severe and more numerous as you progress upward through the stages. For example, you might start out in stage 1 with some occasional breathlessness and coughing, but then acquire additional symptoms (e.g. persistent breathlessness, coughing, and fatigue) by the time you reach stage 3.
Other data can also be used to get a more in-depth picture of a patient's condition or to pinpoint specific health problems and complications. For example, doctors can often learn specifics about a patient's lung condition and function from x-ray images, CT scans, and analyzing other tissues and bodily fluids (e.g. lung fluids, sputum, and blood).

Why Does COPD Progress?
Unfortunately, we simply don't know a lot about why COPD progresses and why it cannot be cured. For example, we don't know exactly why some people who smoke get COPD (and continue to degenerate) while others don't.
However, we do understand many of the mechanics involved in COPD progression, even if we can't always explain why they occur. These mechanics include chronic lung inflammation and the gradual accumulation of damage to tissues in the lungs.
Most of the time, COPD occurs after long-term exposure to lung irritants (like tobacco smoke) that damage sensitive lung tissues over time. In people with COPD, those damaged lung tissues never heal completely, but instead are left weaker and even more sensitive than before.
As a result, the lungs become extra susceptible to inflammation and disease, which causes even more damage and scarring in the lungs. This triggers a vicious cycle in which the lungs are perpetually inflamed and more and more tissues get damaged, making the lungs ever weaker and more sensitive with time.
Unfortunately, there's currently no way to stop or reverse this cycle, which is why COPD is a chronic, life-long, and incurable disease. Of course, that doesn't mean COPD is untreatable; there are many COPD treatments and medications that are effective at controlling COPD symptoms and even slowing down the progression of the disease.
It's important to note that COPD progression is not a smooth or linear process; it can speed up, slow down, or move in stops and starts. Some patients have faster disease progression than others, and some people stay “stable” for months or years at a time before experiencing any significant progression or worsening of their COPD.
Can You Predict COPD Progression?
There are a number of measurable factors that can help predict the likely short-term and long-term health outcomes (or prognosis) for people with COPD. For example, there are a number of risk factors that are linked to quicker disease progression, including:
- Severe COPD symptoms
- Lack of exercise
- Poor nutrition
- Frequent exacerbations
- Frequent hospital stays
- Heart disease
By analyzing these and other factors, it is possible to make educated guesses about things like life expectancy, the speed of disease progression, and how likely you are to develop certain health complications associated with COPD.
However, making these kinds of predictions is both difficult and imprecise. You would need a trained medical expert to come up with any kind of meaningful prediction about the future of your COPD, and even then it would only be an educated guess.
If you want to know more about your COPD prognosis and/or future health risks, you should ask your doctor or respiratory medicine specialist to go over your prognosis with you. An expert who's familiar with your health history and medical records should be able to explain your future health prospects and offer some insight into what your health future might be.
Can You Slow Down COPD Progression?
There has been a lot of research dedicated to figuring out how different COPD treatment methods affect patients' long-term outcomes, including whether or not they can slow down the progression of COPD. This research has identified a number of different treatments and lifestyle changes that are associated with slower progression of COPD, including:
- Quitting smoking
- Getting adequate exercise
- Maintaining a healthy weight
- Completing a pulmonary rehabilitation program
- Minimizing exposure to lung irritants (e.g. air pollution)
- Getting early treatment
- Taking COPD medications consistently and correctly
- Keeping symptoms under control
- Avoiding illnesses and exacerbations
It's important to note, however, that while all of these factors are associated with slower disease progression, it's not always clear whether or not they are directly causing progression to slow. It's difficult to tease apart the exact nature of the relationship; for example, does having well-managed COPD symptoms cause the disease to progress slower, or does having a slower-progressing disease make the symptoms easier to control?
Hopefully, future research can give us more insight into this question and provide new avenues for slowing disease progression in people with COPD. In the meantime, however, most experts agree that you can improve your COPD prognosis by doing the following things: quit smoking, stay active, get treated by a a qualified health professional, and be diligent about taking your medications and following your doctor's advice.

What's Causing My Symptoms? How to Tell the Difference Between Permanent COPD Progression, Temporary Flare-Ups, and Acute Exacerbations of COPD
As we mentioned earlier, it's normal for COPD symptoms to fluctuate from day to day without any apparent reason, or to get worse for a period of months or weeks during a COPD exacerbation. This can make it hard to pinpoint the reason why your symptoms are acting up, including whether it's caused by a temporary or permanent change in your COPD.
Luckily, it is possible to determine the likely cause of an uptick in symptoms if you know what to look for. You just have to pay close attention to the nature, severity, and length of your symptoms, as well as the context in which they occur.
Minor Symptom Flare-Ups
Here we're using the term “minor symptom flare-up” to refer to the normal COPD symptom fluctuations that happen in just about everyone who has COPD. Essentially, we're talking about those days when you wake up and your symptoms are worse than usual, but then they get better within a couple days.
This can happen for all kinds of reasons—maybe the air pollution was especially bad that day or you exerted yourself too much the day before. Flare-ups can also happen for seemingly no reason at all; sometimes you just have bad COPD days.
Most of the time, flare-ups are nothing to worry about and you can get over them on your own. You might need to make some minor changes, like getting some extra rest or using your quick-relief inhaler more often, but you probably won't need any other medical intervention.
That doesn't mean you should take minor flare-ups too lightly, however; sometimes what seems like a minor flare-up can turn into a full-blown COPD exacerbation. It's best to treat flare-ups as a “watch and wait” situation: you shouldn't worry too much, but you shouldn't ignore it either in case it turns out to be something more serious down the line.
COPD exacerbations usually occur when you get sick with a respiratory illness, such as a bacterial lung infection or a simple cold or flu. This results in severe lung inflammation that causes COPD symptoms to worsen significantly for a period of time.
COPD exacerbations can last for weeks or months, and recovery usually requires extra medication or medical intervention. The increased symptoms usually go away when the exacerbation is over, though it can take a long time before they totally get back to baseline.
You can usually tell exacerbations apart from temporary symptom flare-ups because they last longer and tend to be more severe. However, exacerbation severity can vary quite a bit; some are minor and only require minimal intervention, while others are life-threateningly severe.
As a general rule of thumb, you should suspect an exacerbation if you experience worse symptoms (e.g. you feel more breathless, more fatigued, your coughing gets worse, etc.) that don't get better within a few days' time. If they get worse or persist without getting better, you should get in contact with your doctor or follow the corresponding instructions in your COPD action plan.
It's also important to not that, while COPD exacerbations in and of themselves are not a sign of COPD progression, they are linked to permanent COPD progression in a couple of different ways.
First, the frequency and severity of COPD exacerbations are often used as a measure of COPD progression, as they tend to get worse in the later stages of COPD. If you're having more frequent exacerbations, or having more severe symptoms during exacerbations, this could be a sign that your COPD is getting worse.
Exacerbations can also play a direct role in COPD progression, as severe exacerbations can cause irreversible lung damage and lung function loss. In general, the fewer exacerbations you experience, the lower your risk for the additional lung damage associated with exacerbations that, cumulatively, can result in quicker progression of COPD.
This is why preventing exacerbations is such a critical priority for doctors and patients managing COPD. It's also why it is so important to identify and treat exacerbations early, before they get to the point that they become difficult to treat and control.
Compared to minor flare-ups and exacerbations, which tend to come on quickly, COPD progression is a long-term process that tends to happen over the course of months or years. That means you can't judge COPD progression based on just a few days or weeks of symptoms; you have to think long-term, on the order of several months, at least.
So if you've only been experiencing elevated symptoms for a few days or weeks, it's likely much too early to tell if they're caused by permanent disease progression. But if the symptoms persist for months and months without any sign of getting better, it could be a sign that your COPD is getting worse.
Unlike symptoms caused by minor flare-ups and exacerbations, elevated symptoms resulting from permanent COPD progression don't ever really go away. Instead, those symptoms become part of your new baseline—part of your normal, everyday symptoms that you experience as part of the disease.
Elevated baseline symptoms aren't the only sign of COPD progression, however. There are other changes that tend to come hand-in-hand with permanent COPD decline, namely more frequent exacerbations and lung function loss.
Research has well-established that people with COPD tend to experience more severe and frequent exacerbations as the disease progresses. In fact, exacerbations are considered to be “one of the most important predictors of the progression of COPD.”
Lung function is also closely tied to COPD progression. It's the primary criteria used to grade COPD severity and measure how quickly the disease get worse over time. Generally, the quicker your lung function declines, the quicker your COPD is progressing, and the quicker your symptoms will get worse over time.
Clues that Your COPD is Getting Worse: Signs to Watch Out For
In the following sections, we're going to go through some common scenarios that people with COPD experience. Each scenario reflects a situation or circumstance that could be a red flag that your COPD is getting worse.
While none of these scenarios is decisive on its own, each addresses a specific symptom, health complication, or another known indicator of worsening COPD. We hope that, by reviewing these life-like scenarios, you'll get a better idea of what worsening COPD can look like and be better able to recognize the signs of progression in your own life.
You're Spending More Time at the Hospital
Most people with COPD will have to be admitted to the hospital at some point to get treatment for an exacerbation or another complication of COPD. However, people with mild COPD rarely need hospital treatment; it's much more common in the mid-to-late stages of the disease.
People with moderate COPD might occasionally need to be hospitalized for exacerbations, though (depending on doctors' advice) some exacerbations can be treated at home. Those with severe disease tend to be hospitalized more frequently—and have longer hospital stays—both because their exacerbations tend to be more severe, and because treatment can be complicated by the presence of other health complications.
So, if you've been hospitalized for COPD for the first time recently, or have needed hospital treatment more often than usual, it could be a sign that your COPD is getting worse. Of course, it's also possible that you just had bad luck, especially if it's an isolated incident and not an ongoing trend.
More frequent exacerbations can also be a sign that you're not getting (or keeping up with) the treatment you need to properly manage your COPD. But if you're doing everything you're supposed to, and you're still having exacerbations more frequently than before, it's a strong indication that your COPD might be getting worse.
You Can't Get Around As Well as You Used To
People with COPD often struggle with physical exertion, including walking and standing for long periods of time. Mobility problems like this can be both a cause of COPD progression as well as a consequence of worsening COPD.
For example, worsening COPD symptoms (like breathlessness and fatigue) can make it harder to exercise, causing many patients to avoid physical activity. However, lack of exercise tends to make those symptoms even worse, leading to even more mobility issues and quicker physical decline.
This can make it difficult to tell whether mobility problems in COPD patients are simply a symptom of COPD progression or if it's the lack of physica
