Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition characterized by a combination of symptoms associated with emphysema and chronic bronchitis.1

Common symptoms and clinical manifestations include:

  • Breathlessness: Often described as difficulty in exhaling (flow limitation), which leads to increased lung volume.12
  • Cough and Sputum: Early indicators often include a persistent "smoker's cough" and daily production of sputum.13
  • Advanced Symptoms: As the disease progresses, patients may experience significant fatigue, loss of appetite, weight loss, irritability, and psychological depression.2
  • Signs of Complications: In advanced stages, hypoxemia (low blood-oxygen levels) can lead to right-sided heart failure, which may manifest as edema (swelling) in the ankles and engorgement of the neck veins.2

It is important to note that coughing up blood is not a typical feature of COPD and should be investigated for other conditions, such as lung cancer. Additionally, patients may experience episodic worsening of their condition, known as exacerbations, which are often triggered by viral or bacterial infections.1
