Blood in vomit after drinking alcohol

Do not assume alcohol alone explains it. Fresh red blood, dark clots, or brown material resembling coffee grounds can all represent bleeding, even if the episode stops.

Alcohol may irritate the stomach lining. Forceful or repeated retching can also tear tissue near the junction of the oesophagus and stomach. Other possibilities include an ulcer, enlarged veins in the oesophagus related to liver disease, or another lesion in the upper digestive tract.

Oesophageal cancer and stomach cancer can present with vomiting blood, but this symptom by itself does not identify the cause. A clinician may use an examination, blood tests, and a camera test of the upper digestive tract to find where bleeding began.

Stop drinking alcohol and arrange urgent medical care. Do not drive yourself if you feel faint, weak, confused, or unsteady; ask someone to stay with you and contact emergency services.

Avoid taking extra aspirin or anti-inflammatory pain medicines unless a clinician has specifically directed you. Tell the medical team how much blood you saw, what it looked like, whether retching came first, and which medicines you take, especially blood thinners.

Seek emergency help for any definite blood in vomit. Call emergency services immediately if bleeding is ongoing or heavy, or if there is fainting, severe dizziness, confusion, rapid breathing, cold or clammy skin, severe abdominal pain, black sticky stools, or difficulty staying awake.

A small streak after retching still warrants prompt assessment because the visible amount may not show the full extent of bleeding.

Ask where the bleeding may have started, whether your medicines or liver health could contribute, which tests are needed, and when eating or drinking can safely resume. Also ask what changes should bring you straight back for emergency care.
