Small amounts of blood in vomit

Blood may look bright red, form small clots, or appear as dark grains. The amount seen does not reliably show how serious the underlying bleeding is. Contact a medical service promptly and use the emergency warning signs below to decide whether immediate help is needed.

Vomited blood generally comes from the upper digestive tract, including the oesophagus or stomach. Forceful retching can create a tear, and inflammation, an ulcer, enlarged veins, or swallowed blood from the nose or mouth can also be responsible. Oesophageal cancer and stomach cancer can present with vomiting blood, but this symptom alone cannot identify the cause.

A clinician may ask about abdominal pain, repeated vomiting, black bowel movements, swallowing difficulty, liver disease, alcohol use, recent nosebleeds, and medicines that affect clotting or irritate the stomach. Examination and tests are chosen according to the bleeding pattern and your overall condition.

Note the colour and approximate amount, when it happened, and whether the vomit contained food or dark granules. If practical, a photograph can help the clinician. Gather your medicine list, especially blood thinners, anti-inflammatory pain medicines, and cancer treatments.

Do not drive yourself if you feel faint or unwell. Avoid taking an extra dose of any medicine to counter the bleeding. A clinician should advise whether regular medicines should be continued or paused, because stopping some prescribed treatments without guidance can also cause harm.

Call emergency services for ongoing or increasing bleeding, more than a few streaks, black or coffee-ground vomit, fainting, confusion, severe weakness, breathlessness, cold clammy skin, a rapid heartbeat, severe abdominal pain, or black tar-like stools. These signs may accompany significant blood loss and should not wait for a routine appointment.

Ask what source of bleeding is suspected, whether blood tests or an examination of the upper digestive tract are needed, and how your medicines should be managed. Mention any cancer history, swallowing changes, unexplained weight change, persistent indigestion, or previous digestive bleeding.
