Coughing Blood: A Symptom You Cannot Ignore

Coughing up blood — medically called haemoptysis — is one of the most alarming symptoms a person can experience. In Pakistan, where both tuberculosis (TB) and lung cancer are prevalent, understanding the cause is critical.

What is haemoptysis? Haemoptysis is the coughing up of blood or blood-tinged mucus from the lungs or airways. It ranges from small streaks of blood to large volumes, and any amount should prompt medical evaluation.

Important distinction — is it from the lungs? Blood that is coughed up (haemoptysis) comes from the respiratory tract. This is different from vomiting blood (haematemesis), which originates from the stomach.

Causes in Pakistan — TB must be ruled out first:

• Tuberculosis (TB) — the most common cause in Pakistan
• Lung cancer
• Bronchitis or pneumonia
• Bronchiectasis
• Blood clots in the lungs (pulmonary embolism)

When to suspect cancer:

• Age over 40, especially a smoker
• Persistent cough for more than 3 weeks
• Unexplained weight loss
• No fever or signs of infection
• Chest pain

What to do: A chest X-ray is the first essential step and is available at all hospitals in Pakistan. You will also need sputum tests to rule out TB.

Key message: Any coughing of blood requires a chest X-ray and medical evaluation. In Pakistan, always rule out TB first — but do not stop there if symptoms persist.
