Lung Disorders Summary

Introduction

The lungs play a vital role in our respiratory system, constantly expanding and relaxing to facilitate the exchange of oxygen and carbon dioxide. Lung diseases are a major cause of mortality globally due to their susceptibility to infections and disorders.

Asthma

Asthma is a chronic condition that affects the airways, leading to breathing difficulties. It can be influenced by genetic factors and triggered by allergens in the environment. Symptoms include wheezing, shortness of breath, chest tightness, and coughing. Treatment options range from inhalers to breathing machines, emphasizing the importance of early intervention to prevent severe asthma attacks.

Bronchitis

Bronchitis is a viral infection characterized by inflammation of the bronchial passages, commonly seen in heavy smokers. There are two types: acute bronchitis, which lasts a few weeks, and chronic bronchitis, which persists for months. Symptoms include a persistent cough, fever, chest discomfort, and mucus production. Causes can be viral, bacterial, or due to exposure to irritants like smoke or dust. Treatment involves rest, hydration, and avoiding lung irritants.
