COPD stands for chronic obstructive pulmonary disease and consists of two disease processes: emphysema and chronic bronchitis.

copd causes and treatment

By definition, chronic bronchitis is a productive cough that lasts for 3 months in each of 2 successive years.

Emphysema refers to structural changes and airway dilation that lead to airflow limitation.

COPD affects 5% of the population (approximately 12 million people) and is the fourth most common cause of death in the United States. (1)

Stages of COPD

There are many different ways to stage COPD. The most common method is the Global Initiative for Chronic Obstructive Lung Disease (GOLD) system.

This system uses pulmonary function tests and classifies COPD into four stages.

A newer method for classifying COPD is the GOLD ABCD Grading. This grading system is based on the symptoms rather than the forced expiratory volume from the pulmonary tests.

The COPD grade is calculated based on your number of exacerbations per year and your modified Medical Research Council dyspnea scale (mMRC) score.

Causes of COPD

what are the causes behind copd?

The primary culprit for COPD is tobacco abuse.

Other causes of COPD include:

  • Secondhand smoke
  • Air pollution
  • Dust and fumes from one’s occupation
  • Genetic factors, such as alpha-1 antitrypsin deficiency
  • Undiagnosed and untreated asthma

Patients who are young or have a family history of COPD or those without exposure to tobacco should be screened for genetic causes of COPD and alpha-1 antitrypsin deficiency.

Symptoms of COPD

The most characteristic symptoms of COPD include:

  • Shortness of breath or labored breathing, aggravated by both activity and rest
  • Cough with yellow or green phlegm
  • Sputum production
  • Wheezing
  • Chest tightness

Medical Treatment for COPD

medical treatment options for copd

While COPD is not curable, several medical interventions can help manage the symptoms and delay any complications.

1. COPD medications

The following medications may be prescribed:

  • Oral antibiotics for infections
  • Bronchodilators to help relax the airway muscles
  • Oral or inhaled steroids (corticosteroids) to reduce inflammation
  • Mucolytics, such as carbocisteine, to dilute the phlegm for easy expulsion

2. Surgery

Severe cases of COPD may be treated through surgical procedures:

  • Lung volume reduction surgery – The damaged lung tissue is removed to allow the healthy tissues to function better.
  • Lung transplant – Some patients may require a transplant if their lungs are severely affected.

3. Palliative care

Palliative care for COPD is aimed at managing the pain, stress, and other symptoms associated with the disease. It also involves providing support to the patient and family to improve the patients’ quality of life.

Other Treatments

In some severe cases or flare-ups, additional treatments may be required:

1. Supplemental oxygen therapy

In supplemental oxygen therapy, a face mask or nasal prongs are used to supply extra oxygen in severe cases. While it is more common in hospitals, it can also be used at home.

2. Nebulized medicine

A nebulizer converts liquid medicine into a fine mist that is breathed in. This treatment modality delivers a large dose of medicine at once.

3. Noninvasive ventilation (NIV)

A mask connected to a portable machine is used to assist the lungs in breathing.

Recovery Rate of COPD

Everyone’s lung function declines after the age of 25. However, a smoker will have a much more rapid decline in lung function.

Therefore, the goal of most COPD treatment modalities is to reduce the rate of lung function decline and to control the symptoms.

In most patients, once exposure (i.e., tobacco smoke) is avoided, the rate of decline will stabilize to that of a non-smoker.

You can reach this state more readily if you accompany the avoidance of smoke with the necessary treatment, after which your symptoms would stabilize as well.

From an acute exacerbation, about 75% of patients recover to their baseline lung function at about 4–5 weeks.

Diagnosing COPD

diagnosis of COPD

In general, COPD diagnosis is based on the patient’s history, symptoms, and pulmonary function test results.

Certain lab tests can be done to look for genetic mutations that can cause COPD or exclude other causes of shortness of breath.

Other common tests include:

  • Chest X-ray
  • Arterial blood gas test
  • Electrocardiogram
  • Echocardiogram
  • Peak flow test
  • CT scan

Possible Complications of COPD

When COPD is left unmanaged, complications can develop, such as:

  • Swelling in the legs
  • Low energy
  • Anxiety
  • Weight loss
  • Arrhythmia
  • Collapsed lung
  • Pneumonia
  • Osteoporosis
  • Heart failure

When to See a Doctor

It is imperative to visit an emergency room in the following cases if you have been diagnosed with COPD:

  • Increase in shortness of breath
  • Development of blue-gray color in fingernails
  • Exacerbation of symptoms
  • Increased heartbeat
What you may ask your doctor
  • What lifestyle changes can help me manage the condition?
  • What medications do I need?
  • How can I prevent any lung infections?
  • Will allergies make the COPD worse?
  • Can I perform regular exercises safely?
What your doctor may ask you
  • Are you a smoker?
  • Have you experienced any breathing problems recently?
  • Since when did you experience the symptoms?
  • Does anyone in your family have lung problems?

Final Word

Chronic obstructive pulmonary disease refers to multiple lung problems that cause difficulty in breathing.

COPD is a common disease that progresses gradually over time. Therefore, to prevent complications and the decline of health, it is vital to get a timely diagnosis and follow proper treatment.
