What should you know about spit up blood after vomiting?

Forceful or repeated vomiting can irritate the throat or the lining where the food pipe meets the stomach. Small streaks may occur after retching, but blood can also come from a more serious upper digestive bleed. Bright red blood suggests fresher bleeding; dark material or vomit that resembles coffee grounds may have stayed in the stomach longer. The cause may accompany Gastroenteritis, Food Poisoning, or another illness, but the appearance alone cannot identify it. Gallstones, Pancreatitis, and severe headache conditions such as Migraine can cause vomiting, yet blood still requires separate attention.

Stop alcohol and avoid medicines such as aspirin or ibuprofen unless a clinician has specifically told you to take them. Do not eat a large meal while actively vomiting. If there is no ongoing vomiting and you have been told it is safe, take small sips of clear fluid rather than swallowing a large volume at once. Note the colour and approximate amount of blood, how many times you vomited, and any medicines you use. Do not drive yourself if you feel faint or weak; ask someone to stay with you while arranging medical advice.

Seek emergency help now for more than a small streak, coffee-ground vomit, black stool, severe or persistent abdominal pain, fainting, confusion, pale clammy skin, rapid breathing, or inability to keep fluids down. Urgent assessment is also needed if bleeding returns, you take blood-thinning medicine, or you have known liver or stomach disease. Even a small amount should be discussed promptly if you are unsure whether it came from vomiting, the mouth, or the lungs.

Tell the clinician when vomiting began, whether retching came first, what the blood looked like, and whether you have dizziness, pain, fever, or dark stools. Ask whether you need tests, how to replace fluids, and which medicines to avoid until the cause is clear.
