COPD symptoms can vary depending on the amount of damage in the lungs. Symptoms are usually slow to develop and often don’t appear until significant damage has occurred. Symptoms can also come and go and may vary in intensity.
A cough is how the body clears the airways and lungs of mucus and other irritants and secretions. Mucus is usually clear. However, in people with COPD, it may be a yellow color. Often the cough is worst first thing in the morning. You may cough more when you exercise or smoke. The cough may persist every day, even if there are no other symptoms of illness such as a cold or the flu.
When you exhale through narrow or obstructed air passages, you will often hear a whistling or musical sound. This is called wheezing. In people with COPD, it is most often caused by excess mucus blocking the airways. Wheezing doesn’t necessarily mean you have COPD. Wheezing is also a symptom of asthma and pneumonia.
Shortness of Breath (Dyspnea)
As the airways in your lungs become inflamed and damaged and begin to constrict, you might find it difficult to breathe or catch your breath. This COPD symptom is most noticeable during increased physical activity. It can make routine daily tasks, such as walking, doing simple household chores, dressing, or bathing, more difficult. At its worst, it can even occur during rest.
If you have difficulty breathing, you often can’t get enough oxygen to your blood and to your muscles. Without the necessary oxygen, your body slows down and fatigue sets in. You may also feel tired because your lungs are working extra hard to get the oxygen in and the carbon dioxide out, thus draining your energy.
Frequent Respiratory Infections
Because people with COPD have greater difficulty clearing their lungs of bacteria, viruses, pollutants, dust, and other irritants, they can be at greater risk for lung infections such as colds, flu, and pneumonia. Though it’s difficult to avoid infections altogether, practicing good hygiene and getting the correct vaccinations can reduce your risk.
If you’ve had COPD for a long time, you may notice that you’ve been losing weight. The extra energy your body requires to breathe and get enough air in and out of the lungs may be burning more calories than your body is taking in, causing you to lose weight. Weight loss may also occur because fatigue and shortness of breath make eating difficult.
Morning headaches can occur due to higher levels of carbon dioxide in the blood.
Swollen feet and ankles can occur due to increased stress on the heart, which has to work harder to pump blood through the damaged lungs.
