Vomiting up blood clots: urgent next steps

A clot forms when blood sits together and begins to thicken. In vomit, it may come from the food pipe, stomach, or another part of the upper digestive tract. Forceful retching can injure delicate tissue, while ulcers, inflammation, or liver-related bleeding can have other causes. The amount you see does not reliably show how much bleeding has occurred. Dark material resembling coffee grounds can also be digested blood.

Vomiting from Food Poisoning or Gastroenteritis does not make blood clots harmless. These illnesses can cause repeated retching, which may irritate tissue, but a healthcare professional must check the source.

Call emergency services or attend an emergency department immediately. Stay upright if comfortable, or lie on your side if you feel sick or drowsy. Do not drive if you are dizzy or weak. Avoid food, alcohol, aspirin, and anti-inflammatory pain medicines unless a clinician specifically directs you. Keep the vomit or a photo if it is easy to do, and take your medicine list, including any blood thinner.

Treat any blood clot in vomit as an emergency, especially with fainting, light-headedness, weakness, fast heartbeat, pale or clammy skin, confusion, severe pain, black stools, or continued vomiting. Do not wait for a routine appointment or for the colour to return to normal. A pause in bleeding does not prove that the danger has passed.

Ask what may have caused the bleeding, whether you need blood tests or an endoscopic examination, and which medicines are safe while the source is being treated. Mention retching, abdominal pain, black stools, previous ulcers, liver problems, alcohol use, pregnancy, and all medicines or supplements.
