Respiratory illnesses are conditions that affect the lungs and airways, making it difficult to breathe and reducing oxygen flow throughout the body. Common respiratory disorders include asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, and tuberculosis. These illnesses may be caused by infections, allergies, smoking, air pollution, or underlying health conditions. Symptoms often include coughing, shortness of breath, wheezing, chest tightness, and fatigue. Early diagnosis, medication, lifestyle changes, and avoiding respiratory irritants are key to managing these conditions and improving lung health.
