17708 Vomiting Blood

Overview

Vomiting blood means bringing up blood from your stomach or upper gut. The blood may be bright red, dark red, or look like coffee grounds. It is not the same as coughing blood up from your lungs. Vomiting blood can be a sign of bleeding in the upper digestive tract, so it needs urgent medical advice.

Vomiting blood is not a common everyday symptom, but doctors see it in urgent care and hospital settings. Every case is treated as important because it can be serious.

Anyone can vomit blood, at any age. It is more likely in people with stomach ulcers, liver disease, heavy alcohol use, bleeding problems, or those taking medicines that make bleeding more likely. Children may swallow blood after a nosebleed or mouth injury.

Symptoms

Common symptoms

• Blood in vomit that is bright red, dark red, or looks like coffee grounds
• Vomit that contains dark, grainy material
• Black, tarry stools or blood in stool
• Feeling dizzy, lightheaded, or faint
• Stomach pain, heartburn, or nausea
• Pale skin, sweating, or a fast heartbeat
• Feeling weak or short of breath

Symptoms in children

• Blood in vomit after a nosebleed, mouth injury, or dental work
• Vomiting that will not stop, with fewer wet nappies, no tears, or a dry mouth — signs of dehydration
• Being very sleepy, floppy, pale, or hard to wake
• Black stools or blood in the stool

Symptoms in older adults

• Confusion or new weakness can be an important sign of blood loss
• Dizziness when standing, falls, or feeling faint
• Black stools or bleeding that is not obvious
• Worsening breathlessness or chest discomfort
• Higher risk if you take medicines that make bleeding more likely or have liver or kidney disease

Causes

Main causes

• Stomach or duodenal ulcer — an open sore in the stomach or first part of the small bowel
• Gastritis — inflammation of the stomach lining
• A tear in the food pipe from forceful retching or vomiting
• Swollen veins in the food pipe, often due to liver disease
• Inflammation of the food pipe
• Swallowed blood from a nosebleed, mouth injury, or dental work
• Bleeding problems or medicines that make bleeding more likely
• Less often, cancer of the stomach or food pipe

Risk factors

• Heavy alcohol use
• Liver disease or scarring of the liver
• Smoking
• Regular use of certain pain medicines that can irritate the stomach — ask your pharmacist or doctor
• A history of stomach ulcers or ongoing heartburn
• A common stomach infection that can cause ulcers
• Frequent vomiting or retching
• Older age and serious illness

When to see a doctor

See a doctor urgently if:

• You have vomited any blood, even a small streak
• You have black tarry stools or blood in your stool
• You feel dizzy, faint, weak, or short of breath
• You have severe stomach pain or ongoing vomiting
• You are pregnant or have liver disease and notice blood

Book a routine appointment if:

• Follow up after treatment for vomiting blood, even if you feel better
• Talk to your doctor if you have repeated heartburn, stomach pain, or trouble swallowing
• Ask your doctor or pharmacist to review medicines that may irritate the stomach or raise bleeding risk

Diagnosis

A doctor will ask what happened, how much blood you saw, and whether you have pain, dizziness, or black stools. They will check your breathing, pulse, blood pressure, and belly. They will also ask about your medicines, alcohol use, and past stomach or liver problems. Tests can help find the source of bleeding.

Tests that may be done

• Blood tests to check for low blood counts, anemia, and how well your liver and kidneys are working
• Stool tests to look for signs of bleeding
• Endoscopy — a thin flexible camera tube passed through the mouth to look at the food pipe, stomach, and first part of the small bowel
• Imaging such as a CT scan if more information is needed
• Checks for a stomach infection that can cause ulcers

What to expect at your appointment

You may be seen quickly in an emergency department or urgent clinic. Staff may watch your vital signs and keep you for observation. You may need a drip for fluids, and sometimes an endoscopy is done urgently. The team will explain each step and ask for your consent before tests or procedures.

Treatment

Treatment aims to stop the bleeding, replace any lost fluid or blood, and treat the underlying cause. The right plan depends on how much blood was lost, your general health, and the cause found. Some people need only short care; others need to stay in hospital.

Self-care at home

• Call for urgent help. Do not drive yourself to hospital if you feel faint or unwell.
• If you feel faint, lie down and ask someone to stay with you.
• Do not eat or drink until a doctor advises you, especially if bleeding is active.
• Do not take over-the-counter pain or heartburn medicines without checking with a pharmacist or doctor first.
• Avoid alcohol and smoking while you recover.
• Keep a list of your medicines and health conditions to show the medical team.

Medical treatments

Doctors may give fluids and, if needed, blood through a drip. They may use medicines to protect the stomach, reduce acid, or treat a stomach infection. If bleeding is found during endoscopy, the doctor may stop it using small clips, bands, injections, or heat treatment. They may also adjust medicines that raise bleeding risk, but only under medical advice.

When is surgery considered?

Surgery is not usually needed. It may be used if bleeding cannot be controlled with endoscopy, if there is a hole in the stomach or bowel, or if a growth needs treatment. Your medical team will discuss the risks and benefits with you.

Living with this condition

After treatment, follow your discharge instructions closely. Watch for bleeding, black stools, dizziness, or feeling more unwell, and seek help if these return. Keep follow-up appointments and tell any doctor or dentist about your history of vomiting blood.

Lifestyle tips

• Avoid alcohol while you heal and limit it long term
• Do not smoke, and ask for help to stop if needed
• Eat small, gentle meals if your doctor advises
• Take medicines exactly as prescribed and ask before starting new ones
• Manage stress and get enough rest
• Tell your pharmacist about your bleeding history before buying over-the-counter medicines

Diet and exercise

There is no single diet that treats vomiting blood. If your doctor advises a gentle diet, choose small meals and avoid foods that seem to irritate your stomach. After recovery, gentle walking can help you feel better. Avoid heavy lifting or strenuous exercise until your doctor says it is safe.

Mental health and emotional wellbeing

Vomiting blood can be scary, and it is normal to feel anxious afterwards, especially while waiting for test results. Tell your doctor if worry is affecting your sleep, eating, or daily life. If you feel in crisis or unsafe, contact your local emergency number or a local crisis service straight away.

Prevention

Not every case can be prevented, but you can lower your risk. Treat stomach ulcers and ongoing heartburn, limit alcohol, avoid smoking, and use pain medicines carefully. If you have liver disease, keep up with your specialist care.

Vaccines

There is no vaccine for vomiting blood itself. Some vaccines can lower the risk of infections that affect the liver. Ask your doctor or pharmacist which vaccines are recommended for you.

Screening programmes

There is no routine screening test for vomiting blood. If you have risk factors such as liver disease or a history of ulcers, your doctor may suggest checks for those conditions.

Complications

If left untreated

• Severe blood loss that can lead to shock
• Anemia and ongoing tiredness
• The need for urgent procedures or blood replacement
• The underlying cause getting worse, such as an ulcer, liver disease, or less often cancer
• Continued black stools or bleeding

Long-term outlook

Most people do well when they get prompt medical care. The exact outlook depends on the cause and how quickly bleeding is controlled. Many causes are treatable, and doctors have clear steps to help. Seeking help early makes a real difference.
