What should you know about blood after cough?

Short answer

Blood after coughing should be assessed by its amount, appearance, recurrence, and accompanying symptoms rather than ignored.

This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

Where the blood may come from

Small streaks can follow forceful coughing that irritates the throat or airway. Blood may instead drain from a nosebleed or gum and appear during a cough. Respiratory illnesses such as [Acute Bronchitis](/conditions/acute-bronchitis/) or [Common Cold](/conditions/common-cold/) can produce mucus with blood. Ongoing cough, wheeze, or repeated blood needs a clinician’s assessment; causes include [Asthma](/conditions/asthma/) and [Bronchiectasis](/conditions/bronchiectasis/).

What to do

Spit the material into a tissue so you can observe whether it is mucus-streaked or mainly blood. Note when it started, how often it occurs, and whether you take medicines that affect clotting. Rest, drink fluids if you can, and avoid smoking or strenuous exertion until assessed. Do not self-treat repeated bleeding with leftover antibiotics. A clinician may ask about reflux, nasal symptoms, allergies, and the pattern of your cough.

When to seek care

Seek emergency help for more than a trace of blood, difficulty breathing, chest pain, faintness, confusion, blue lips, or rapidly worsening symptoms. Get prompt medical advice for repeated blood, fever, night sweats, unexplained weight change, or a cough that does not settle. [Chronic Cough](/conditions/chronic-cough/) deserves review even when the blood is only streaking.

Questions for your doctor

Could the blood be from my nose or throat? Do I need an examination or imaging? Which medicines should I continue?

Questions people ask

Is a blood-streaked cough always serious?

Not always, but new or repeated blood should be reviewed because the source can be outside the lungs or within the airways.

Can a cold cause blood after coughing?

Irritated airways during a cold can cause streaking, but worsening symptoms or recurrence warrants medical advice.
