Vomiting blood, black tarry stool or a substantial amount of fresh blood require urgent assessment.
Red or coffee-ground-like vomit, black sticky stool or passing a large amount of blood may indicate gastrointestinal bleeding. Dizziness, weakness, pallor or fainting make it more urgent. Do not take anti-inflammatory painkillers without medical advice.
Medical principle
In emergencies, the aim is to recognise danger and obtain professional care quickly, not to diagnose at home. Symptom onset, underlying conditions and medicines are important information for the care team.
Practical steps that may help
- Note the exact time symptoms began and call local emergency services.
- Do not leave the person alone; give nothing to eat or drink if awareness is reduced.
- Prepare the list of medicines, allergies and underlying conditions for the care team.
When should you seek medical care?
Altered awareness, stroke signs, chest pain, severe breathlessness, substantial bleeding, anaphylaxis and severe dehydration require immediate action, not a routine appointment.
