What does vomiting blood feel like with stomach cancer?
Short answer
With Stomach Cancer, vomiting blood may follow nausea and appear bright red or dark like coffee grounds; vomiting blood is a common presentation of Stomach Cancer, though other causes are possible.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

How bleeding may present
Blood that has just entered the stomach may look red. Blood altered by stomach acid can look brown, black, or grainy. You might feel retching, light-headedness, unusual tiredness, or upper abdominal discomfort. Black, sticky stools can be another sign of bleeding. The symptom alone cannot show whether stomach cancer is present or identify the exact source. A clinician may use blood tests, imaging, or upper endoscopy to investigate. See [Stomach Cancer](/conditions/stomach-cancer/) for related information.
What to do after an episode
Seek urgent medical advice even if the bleeding stops. If possible, record what the vomit looked like, whether it recurred, and which medicines you take, especially blood thinners or anti-inflammatory medicines. Do not drive if you feel dizzy. A clinician may advise you about eating, drinking, and medicines while arranging assessment.
Emergency warning signs
Call emergency services for continuing blood loss, fainting, confusion, severe weakness, fast breathing, clammy skin, chest pain, or difficulty breathing. Vomiting blood with severe abdominal pain or black stools also needs emergency care.
Questions for your doctor
How will you locate the bleeding? Should I have an endoscopy or blood tests? Could my medicines irritate the stomach or affect clotting, and what should I do if bleeding returns?
Questions people ask
Is dark vomit always cancer?
No. Dark vomit can reflect altered blood, but several conditions can cause it and assessment is needed.
What other sign should I mention?
Tell the clinician about black stools, dizziness, weakness, pain, repeated vomiting, and medicines that affect bleeding.
