When a child throws up blood, take it seriously

Blood in child vomit can look bright red, dark red, or like coffee grounds. A few streaks may happen after forceful vomiting, a nosebleed, or irritation in the mouth or throat. Larger amounts, repeated episodes, or vomiting blood along with weakness, trouble breathing, severe belly pain, black stools, or dehydration need urgent medical attention. This page helps parents understand what to do if a child vomits blood and when emergency care may be needed.

Common reasons a child may vomit blood

Irritation after repeated vomiting

Forceful vomiting can irritate the throat or upper digestive tract and cause small streaks or specks of blood.

Swallowed blood

A nosebleed, bleeding gums, or a mouth injury can lead to blood being swallowed and then vomited.

Bleeding in the stomach or esophagus

Less commonly, blood in vomit can come from the digestive tract and may need urgent evaluation, especially if the amount is more than a few streaks.

Signs that vomiting blood in a child may be an emergency

More than a small amount of blood

If your child vomited more than a few teaspoons, keeps vomiting blood, or the blood looks dark or clotted, seek urgent care right away.

Concerning symptoms with it

Go now if your child also has trouble breathing, fainting, severe stomach pain, unusual sleepiness, black stools, or signs of shock.

Young babies or medically fragile children

Baby vomiting blood should be assessed promptly, especially in newborns, infants, or children with bleeding disorders or chronic medical conditions.

What parents can do right now

Check how much blood there was

Try to note whether it was just a few streaks, a small amount mixed with vomit, or more than a few teaspoons.

Look for the source

Check for a recent nosebleed, bleeding from the mouth, cracked lips, or coughing up blood that may have been swallowed.

Use the assessment for next steps

Answer a few questions to get personalized guidance on whether home monitoring, same-day care, or emergency evaluation is the safest next step.

Frequently Asked Questions

Is vomiting blood in a child an emergency?

It can be. A few small streaks after repeated vomiting may come from irritation, but larger amounts, repeated blood in vomit, dark or coffee-ground material, or symptoms like weakness, trouble breathing, severe pain, or black stools should be treated as urgent.

Why is my toddler vomiting blood?

Toddler vomiting blood can happen from swallowed blood after a nosebleed, irritation from forceful vomiting, or less commonly bleeding from the digestive tract. The amount of blood and your child’s other symptoms help determine how serious it may be.

What should I do if my child threw up blood once?

Start by checking how much blood there was and whether your child has other symptoms. A single episode with only a few specks may be less concerning than repeated vomiting or a larger amount. Use the assessment to get guidance tailored to your child’s situation.

Is baby vomiting blood different from an older child vomiting blood?

Yes. Babies can become dehydrated more quickly, and blood in infant vomit should be assessed promptly. In some cases, a baby may swallow blood from a breastfeeding parent’s cracked nipple, but it is still important to consider other causes.

What does blood in child vomit look like?

It may appear as bright red streaks, small specks, dark red fluid, or material that looks like coffee grounds. The appearance can offer clues, but it does not replace medical assessment when the amount is significant or symptoms are concerning.
