Understanding Chronic Obstructive Pulmonary Disease (COPD)

  • COPD is a common lung disease that obstructs the airflow, leading to difficulty breathing and other symptoms.
  • Risk factors include smoking, secondhand smoke, air pollution, genetics, and comorbidities like cardiovascular disease.
  • Treatment includes smoking cessation, regular exercise, proper nutrition, and medication as prescribed.
  • With the proper management and lifestyle changes, you can lead an active and fulfilling life even with COPD.

Are you experiencing breathlessness or coughing? Maybe you are also getting tired quickly or wheezing. These symptoms could indicate a health condition known as a chronic obstructive pulmonary disease (COPD). COPD is a common lung disease that makes breathing difficult by obstructing airflow. It can sound scary, but the good news is that you can lead a fulfilling life with the right management, even with COPD. Here’s what you need to know about it:

What is COPD?

COPD includes progressive and debilitating lung diseases, including emphysema and chronic bronchitis. It is a severe condition that can significantly reduce your quality of life if left untreated. COPD is caused by damage to the airways in the lungs, leading to difficulty exhaling air from the lungs. This makes it hard for you to breathe normally and can lead to shortness of breath, coughing, and other symptoms.

Risk Factors

Anyone can get this disease, but others are more susceptible to it than others. Here are some common risk factors for the disease:

Smoking and Secondhand Smoke

Cigarette smoking is the most common risk factor for COPD. It is estimated that up to 90% of COPD cases are caused by smoking. Cigarette smoke irritates and inflames the airways, causing them to narrow and produce excess mucus. Over time, this can lead to permanent lung damage. Additionally, exposure to secondhand smoke can also cause COPD. If you are a smoker, the best way to reduce your risk is to quit smoking. If you don’t smoke, avoid being around people who do.

Air Pollution

Exposure to air pollution can also increase your risk of developing COPD. Air pollution includes particulate matter, chemicals, and other substances released into the air by industrial equipment, cars, and other sources. When you breathe in polluted air, the harmful particles can irritate your lungs and cause inflammation. This can lead to the development of COPD. To reduce your risk, avoid areas with high pollution levels or wear a mask if you have to work in such areas.


Certain genetic factors can also contribute to the development of COPD. Alpha-1 antitrypsin deficiency is a rare genetic disorder that can lead to COPD. This occurs when the body does not produce enough of a certain protein that protects the lungs from damage. If you have a family history of COPD or alpha-1 antitrypsin deficiency, talk to your doctor about getting tested.


COPD is also comorbid with other diseases. Here are some common comorbidities of this disease:

Cardiovascular Diseases

Research shows that the leading comorbidity for COPD patients is cardiovascular disease (CVD) – accounting for more than half of all comorbidities in these patients. The prevalence of CVD increases with the progression of COPD, and it’s often associated with severe COPD.

Studies have shown that cardiac function in COPD patients is altered, which causes a decrease in perfusion, resulting in hypoxemia or low oxygen in the blood. An exacerbation of COPD can further stress the heart, leading to chronic heart failure. Managing CVD in COPD patients is focused on controlling risk factors like smoking, hypertension, and high cholesterol, as well as controlling inflammation and providing patients with appropriate oxygen therapy.

Depression and Anxiety

Depression and anxiety are widely prevalent among COPD patients, with rates ranging from 22% to 42%. Patients with COPD often report a decrease in physical activity and a decrease in social interaction due to their breathing difficulties. This leads to feelings of depression and anxiety among these patients.

Studies show that depression and anxiety are associated with an increased risk of hospitalization, reduced quality of life, and mortality in COPD patients. The management of depression and anxiety in COPD patients mainly includes counseling, behavioral therapies, and antidepressant medication if severe.


Osteoporosis is a medical condition characterized by bones becoming brittle and weak, leading to fractures. COPD patients are at higher risk of developing this condition due to their low mobility, use of corticosteroids, and smoking history. A study published in Thorax shows that the prevalence of osteoporosis among COPD patients is about 23%. The management of osteoporosis in COPD patients mostly involves using calcium and vitamin D supplements, bisphosphonates, and fall prevention.

Varicose Veins

Another common comorbidity in COPD patients is varicose veins. About 29% of COPD patients have this condition, according to a study published in the journal Lung India. Varicose veins are caused by increased pressure on the walls of veins due to weakened valves, leading to swollen and bulging veins. This is why people with COPD are suggested to get varicose vein treatment to reduce the chances of getting this disease. This treatment might also help with other symptoms associated with COPD.

Dealing With COPD

COPD is a chronic and progressive disease, meaning the symptoms will worsen if left untreated. The best way to manage COPD is to catch it early and start treatment immediately. Here are some tips for managing your COPD:

Quit Smoking

Smoking cessation is the most crucial step in managing COPD. Quitting smoking is the best way to reduce your risk of developing COPD and can help slow the disease’s progression.

Regular Exercise

Regular exercise helps to improve lung function, reduce breathlessness, and increase strength in patients with COPD. Light aerobic exercises like walking or swimming for at least 30 minutes daily can help you manage your symptoms.

Maintain Proper Nutrition

Good nutrition is essential for those with COPD, as it helps to keep your lungs and body healthy. Eating a diet rich in fruits, vegetables, and lean proteins can give your body the nutrients it needs to fight off infection and inflammation caused by COPD.

COPD is a serious but manageable condition. With the right management and lifestyle changes, you can lead an active and fulfilling life even with COPD. Talk to your doctor about best managing your symptoms and getting the treatment you need for a better quality of life.
