What should you know about throwing up blood liver?

Blood in vomit may look bright red, dark brown, or like coffee grounds. Advanced liver scarring can raise pressure in veins that carry blood through the liver. Enlarged veins in the food pipe or stomach may then bleed. A stomach ulcer, irritation, a tear after repeated retching, or another digestive condition can also cause bleeding. The appearance of the blood does not show the cause by itself.

Treat this as an emergency symptom. Stop eating and drinking until a clinician gives instructions, keep a record of medicines taken, and do not take aspirin or anti-inflammatory pain medicines unless a clinician has specifically advised them. If possible, have someone stay with you and bring your medicines. Do not drive yourself if you feel faint, confused, or weak.

Seek emergency care immediately for any blood in vomit, especially with black stools, dizziness, fainting, fast breathing, confusion, severe weakness, belly pain, or pale clammy skin. These signs can accompany significant blood loss. Call local emergency services if the bleeding is ongoing, you cannot stay awake, or you collapse. Even if the bleeding stops, urgent assessment is still needed.

Ask what may have caused the bleeding, whether tests are needed to locate it, which medicines should be paused, and how liver disease changes your follow-up plan. Tell the team when the vomiting began, how the blood looked, how often it happened, and whether you have had black stools or faintness.
