It is an umbrella term used for a group of chronic lung diseases that cause progressive and irreversible airflow obstruction, making it harder to breathe over time. It includes two main conditions:</p><ul><li><p><strong>Chronic bronchitis</strong>, where the airways that carry air from the windpipe to the lungs become inflamed and produce excess mucus, leading to persistent coughing.</p></li><li><p><strong>Emphysema</strong>, in which the tiny air sacs at the end of the airways in the lungs responsible for oxygen exchange, get damaged. </p></li></ul>.<p>Asthma affects both children and adults and is the most common chronic condition among children. It occurs when the airways in the lungs become swollen, making them overly responsive to allergens and irritants like dust, pollen, fumes, and pollution. This inflammation causes the muscles around the airways to tighten, resulting in narrow passages that make it difficult to breathe.</p>.<p>COPD usually develops after the age of 40, typically in people who smoke or have had long-term exposure to harmful inhaled noxious particles, like air pollution. However, given the progressive nature of the disease, younger people in high-risk groups, who have had exposure to irritants, should still be mindful of the potential long-term risks. In contrast, asthma can start at any age, often in childhood or early adulthood. Asthma risk factors include family history, allergies, and exposure to environmental irritants ranging from house dust and mites to chemicals or fumes. </p><p>Furthermore, asthma symptoms often worsen on exposure to factors like irritants, allergies, or exercise, resulting in attacks (exacerbations) which can be mild to severe.

Between attacks, breathing may return to normal with little to no difficulty.

It often includes a combination of long-term controller medications to reduce airway inflammation and quick-relief inhalers to open airways during attacks. Avoiding triggers, like pollution or pet dander, is also key to managing asthma. For COPD, treatment focuses on inhaled medications like bronchodilators to ease breathing by relaxing airway muscles.
