The most common signs and symptoms of lung disease include:

  • Cough: A persistent cough is a primary indicator of conditions affecting the bronchial tree. A cough that produces sputum is often associated with inflammatory or malignant diseases, such as bronchitis.1
  • Dyspnea (Shortness of Breath): This is a major symptom that may arise acutely or develop insidiously, often manifesting as difficulty completing routine physical tasks.1
  • Chest Pain: Frequently associated with pneumonia or inflammation of the pleura, this pain is often felt during deep breaths.1
  • Hemoptysis: The presence of blood in the sputum is a serious sign that may indicate inflammation, tuberculosis, or a tumour.1
  • Other Indicators: Patients may also experience wheezing, "clubbing" (swelling of the fingertips), or enlarged lymph nodes in the neck.1

General symptoms such as fatigue, loss of appetite, weight loss, and malaise are also common, as many lung diseases have a debilitating systemic effect. Because early symptoms are often nonspecific, medical evaluation is essential for an accurate diagnosis.1
