What Is COPD? Understanding Chronic Obstructive Pulmonary Disease

What is COPD? This abbreviation stands for Chronic Obstructive Pulmonary Disease, a group of lung conditions characterized by obstruction in airflow, making it difficult to breathe. In 2019, chronic obstructive pulmonary disease (COPD) resulted in 3.23 million deaths globally, making it the third most common cause of death worldwide. Understanding the causes, symptoms, diagnosis, and treatment options for COPD is crucial for patients.

Understanding COPD: Causes, Symptoms, and Diagnosis

To put it simply, COPD is a group of lung diseases, primarily chronic bronchitis and emphysema, that gradually worsen over time. But what is COPD in medical terms? This condition limits airflow and makes it harder to breathe. Also, this means that fewer body tissues and organs get oxygen. Symptoms may be mild at first, for instance, frequent coughing and shortness of breath. 

What is the difference between asthma and COPD? Asthma is usually diagnosed in childhood and triggered by an allergen. COPD, in turn, affects mostly people over the age of 40 and smokers. As the disease progresses, it becomes much more difficult to breathe. Without proper COPD treatment, it may trigger heart, lung, and other issues. So, to answer the question of what is COPD —it is also one of the leading causes of hospitalizations and death in developed countries.

Types of COPD: Chronic Bronchitis and Emphysema

COPD can be divided into two key types: chronic bronchitis and emphysema. The former involves inflammation and irritation in the lining of one’s airways, leading to excessive mucus production and a persistent cough. Emphysema is characterized by damage to the air sacs in the lungs and the wall between them, reducing their elasticity and impairing airflow.

Risk Factors for Developing COPD

What is COPD caused by? Several risk factors increase the risk of developing COPD:

• Smoking
• A history of childhood respiratory infections
• A history of asthma
• People with asthma
• Exposure to dust, fumes, and chemicals
• Air pollution
• Genetics
• Age 40 and older

It’s important to remember that each patient’s symptoms are different. Only a healthcare professional can create an optimal treatment plan.

Medications for Managing COPD Symptoms

Now that we know what is COPD disease and the possible treatment options, it’s time to talk about medications. Finding the right medication and dosage to effectively manage symptoms and minimize flare-ups of COPD implies some trial and error. But there exist numerous alternatives to consider:

• Antibiotics and antivirals to treat bacterial or viral infections
• Vaccines to help protect and prevent respiratory diseases
• Bronchodilators to relax and widen the airways
• Corticosteroids to reduce the risk of flare-ups
• Phosphodiesterase-4 inhibitors to relieve inflammation
• Theophylline to improve lung function and levels of oxygen

Combination therapies may also be a part of the treatment plan. For example, inhalers containing both bronchodilators and corticosteroids can be prescribed for long-term maintenance.

Lifestyle Changes for COPD Management
