Understanding COPD: Causes, Symptoms, and Treatment

The condition a smoker has with difficulty breathing due to constantly inflamed and mucus-filled airways is known as Chronic Obstructive Pulmonary Disease (COPD). COPD is a progressive lung disease that includes two main conditions: emphysema and chronic bronchitis.

Emphysema

- Damages the air sacs in the lungs (alveoli), causing them to lose elasticity and become enlarged. This makes it harder for oxygen to pass from the lungs into the bloodstream and leads to shortness of breath.

Chronic Bronchitis

- Involves long-term inflammation and narrowing of the airways, resulting in excessive mucus production. The constant inflammation and mucus make breathing difficult and can cause coughing, wheezing, and shortness of breath.

Smoking is a major risk factor for COPD, as the inhaled toxins irritate the airways, causing inflammation, damage, and narrowing over time. COPD can significantly impact a person's quality of life and can lead to severe breathing difficulties, reduced activity tolerance, and other complications.
