The short explanation
Please take him to hospital now, or call 112. Vomiting blood with dizziness is a medical emergency. In someone who drinks alcohol regularly, the bleeding may come from a tear in the food pipe after retching, a stomach ulcer, or swollen veins in the food pipe caused by liver damage, which can bleed heavily. Dizziness suggests he may have lost a significant amount of blood. Doctors need to check his blood pressure, heart rate and haemoglobin, give fluids or blood if needed, and usually arrange an endoscopy to find and treat the bleeding source. Do not give him alcohol, food or painkillers while waiting.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Take a list of his medicines with you, especially blood thinners or painkillers.
- If he loses consciousness, lay him on his side so he does not choke, and stay with him.
- After he recovers, his doctors will likely discuss liver health and support to reduce or stop drinking.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you where he is bleeding or how serious it is. He needs urgent assessment in hospital.

Take these with you. You can add any of them to an appointment card.
- Where is the bleeding coming from?
- Does he need a blood transfusion or endoscopy?
- Is his liver affected by alcohol?
