What should you know about blood tinged sputum?

Sputum comes from the lower airways, although blood can sometimes be mixed in from the nose or throat. Acute Bronchitis can inflame airway surfaces and make coughing produce streaks. Pneumonia may cause phlegm alongside fever and feeling unwell. Bronchiectasis and COPD can lead to ongoing phlegm and recurrent bleeding. Chronic Sinusitis may cause drainage that is mistaken for chest sputum.

The colour and amount matter, but neither provides a diagnosis alone. A clinician may listen to your chest, check oxygen levels, and decide whether imaging or a sputum sample is appropriate.

Take note of the amount, colour, frequency, and whether blood appears after vigorous coughing. Rest, drink fluids if suitable for you, and avoid smoking and dusty environments. Do not start leftover Antibiotic Treatment: antibiotics are useful only for selected bacterial illnesses and need professional guidance. Keep prescribed inhalers available and use them as directed.

Call emergency services for substantial or ongoing bleeding, severe breathlessness, chest pain, faintness, confusion, or blue lips. Arrange same-day advice for fever, worsening cough, or repeated blood-streaked sputum. People with COPD, bronchiectasis, or medicines that affect clotting should contact their care team promptly when this symptom appears.

Ask whether the blood is likely from the lungs, whether your regular treatment needs adjustment, and which symptoms should lead you to emergency care.
