What condition is described by difficulty in breathing due to the narrowing of the airways?

The condition characterized by difficulty in breathing due to the narrowing of the airways is asthma. Asthma is a chronic inflammatory disorder of the airways, which leads to episodes of wheezing, breathlessness, chest tightness, and coughing. The narrowing of the airways occurs as a result of bronchoconstriction, inflammation, and increased mucus production in response to various triggers, such as allergens, irritants, or exercise.

In contrast, while Chronic Obstructive Pulmonary Disease (COPD) also involves airflow limitation and can lead to difficulty breathing, it primarily results from long-term exposure to harmful substances, such as cigarette smoke, rather than acute narrowing of the airways. Pneumonia is an infection that causes inflammation in the air sacs of the lungs, which can lead to fluid accumulation and difficulty breathing, but it is not due to airway narrowing specifically. Supraventricular Tachycardia refers to a rapid heart rate originating above the ventricles of the heart and does not relate to breathing difficulties caused by airway constriction.
