Chronic obstructive pulmonary disease (COPD)

Symptoms

• Shortness of breath: This is often the most noticeable symptom of COPD and can range from mild to severe. It may be worse with activity and improve with rest.
• Cough: People with COPD may have a persistent cough that produces phlegm or mucus.
• Chest tightness: Some people with COPD may experience a feeling of tightness in their chest.
• Wheezing: COPD can cause the airways to narrow, which can cause a whistling sound when you breathe.
• Fatigue: COPD can cause fatigue due to the difficulty breathing and other symptoms.

Causes

• Air pollution: Exposure to air pollution, such as from traffic or industrial emissions, can contribute to the development of COPD.
• Occupational exposure: Exposure to certain substances in the workplace, such as dust, chemicals, and fumes, can increase the risk of COPD.
• Genetics: Some people may have a genetic predisposition to COPD, which means that they are more likely to develop the condition due to inherited factors.

Risk factors

• Smoking: Smoking is the leading cause of COPD and is responsible for most cases of the condition.
• Exposure to secondhand smoke: Exposure to secondhand smoke, either through smoking or living with someone who smokes, can increase the risk of COPD.
• Age: COPD typically develops in people over the age of 40, and the risk of the condition increases with age.
• Occupation: Certain occupations, such as farming, construction, and manufacturing, can increase the risk of COPD due to exposure to dust, chemicals, and fumes.
• Family history: People with a family history of COPD may be more at risk of developing the condition.
• Gender: Men are more likely to develop COPD than women.

Complications

• Respiratory failure: In severe cases, COPD can cause respiratory failure, a condition in which the lungs are unable to adequately oxygenate the blood.
• Heart problems: COPD can increase the risk of heart problems, such as heart attack, angina, and heart failure.
• Anemia: COPD can cause anemia, a condition in which there is a reduced number of red blood cells or a reduced amount of hemoglobin in the blood.
• Depression and anxiety: COPD can cause or contribute to the development of depression and anxiety due to the physical and emotional impact of the condition.
• Lung infections: COPD can increase the risk of lung infections, such as pneumonia and bronchitis.

How to diagnose it?

• Physical exam: A physical exam can help a healthcare provider assess your overall health and check for signs of COPD, such as shortness of breath and a persistent cough.
• Medical history: A healthcare provider will ask about your medical history, including any exposures to irritants such as tobacco smoke or air pollution, and any respiratory symptoms you have experienced.
• Spirometry: This test measures how much air you can exhale and how quickly you can exhale it. It is the most common test used to diagnose COPD.
• Chest X-ray: A chest X-ray can help a healthcare provider see the structure of your lungs and check for signs of COPD, such as damage to the airways.
• CT scan: A CT scan can create detailed images of the inside of the body and can be used to check for signs of COPD, such as damage to the airways and lungs.

How to prevent it?

• Avoid smoking: Smoking is the leading cause of COPD, and quitting smoking is the most effective way to reduce your risk of the condition.
• Avoid exposure to secondhand smoke: Exposure to secondhand smoke can also increase the risk of COPD. Avoid being around smokers and avoid places where smoking is allowed.
• Avoid exposure to air pollution: Exposure to air pollution, such as from traffic or industrial emissions, can increase the risk of COPD. Avoiding exposure to air pollution, or taking steps to protect yourself when you are exposed, can help reduce your risk of the condition.
• Wear a mask or respirator if you work in a dusty or toxic environment: If you work in a job that exposes you to dust, chemicals, or other irritants, wearing a mask or respirator can help protect your respiratory system.
• Get vaccinated: Vaccines are available to protect against certain types of pneumonia, which can be a complication of COPD. These vaccines are especially important for people with COPD, as they are at an increased risk of pneumonia.

When do you need to see a doctor?

It is important to see a healthcare provider if you have any symptoms of COPD, especially if you are at increased risk of developing the condition. Symptoms of COPD can include shortness of breath, a persistent cough, chest tightness, and wheezing. 

It is especially important to see a healthcare provider if you have severe shortness of breath, a persistent or productive cough that does not go away, or if you have difficulty performing activities you used to be able to do. These symptoms can indicate a more serious case of COPD that may require immediate treatment. 

If you have underlying health conditions, are over the age of 40, or have a history of smoking or exposure to irritants, it is important to be extra vigilant about seeking medical attention for any respiratory symptoms, as you may be at an increased risk of COPD.
