What blood in a cough is called

Haemoptysis describes blood coming from the lower respiratory tract and being expelled by a cough. It is often mixed with mucus and may look bright red or pink. Blood from a nosebleed can drip into the throat, and bleeding gums can be mistaken for airway bleeding. Dark, coffee-like vomit suggests a different route and needs medical assessment.

Possible respiratory triggers include acute bronchitis, asthma, bronchiectasis, bronchiolitis in young children, and a chronic cough. A common cold, allergic rhinitis, or acid reflux may irritate nearby tissues. The term describes what happened; it does not provide the cause.

Write down the timing, colour, amount, number of episodes, and whether blood was mixed with mucus. Note fever, chest pain, breathlessness, wheezing, recent infection, smoking or vaping, and medicines that affect clotting. Arrange medical advice for unexplained, recurrent, or persistent bleeding.

Get emergency help if bleeding is heavy or continuous, or if it comes with breathing difficulty, chest pain, faintness, confusion, or blue lips. Seek prompt review for repeated episodes, worsening illness, fever, night sweats, unexplained weight loss, or a cough that persists. Do not delay if you have a bleeding disorder or take anticoagulants.

Ask whether the episode meets the definition of haemoptysis, where the blood may have originated, and whether examination or chest tests are appropriate. Ask how to manage your current medicines while bleeding is being assessed.
