Alcohol Poisoning

Overview

Alcohol poisoning happens when someone drinks a large amount of alcohol in a short time. The body cannot process it fast enough, and alcohol builds up to dangerous levels in the blood. This can affect the brain, breathing, and heart, and can be life-threatening.

It is not rare. Many people end up in hospital emergency departments each year with alcohol poisoning, especially young adults. Many more cases go unreported because people try to recover at home without medical help.

It can affect people of any age, but it is most common in teenagers and young adults who binge drink. Men are more likely to need hospital care for alcohol poisoning, but women can be more sensitive to the effects of alcohol.

Symptoms

Common symptoms

• Confusion or slurred speech
• Vomiting
• Seizures
• Slow or irregular breathing (fewer than 8 breaths per minute, or pauses longer than 10 seconds)
• Cold, pale, or blue-tinged skin
• Low body temperature
• Passing out and being hard to wake

Symptoms in children

• Children and teenagers can become very ill from even small amounts of alcohol.
• Watch for stumbling, slurred speech, vomiting, confusion, or unusual sleepiness.
• Never give alcohol to a child or teenager, even in tiny amounts.

Symptoms in older adults

• Older adults are more sensitive to alcohol and can become confused, drowsy, or unsteady very quickly.
• They may be taking medicines that interact with alcohol, which can make symptoms worse or harder to recognise.
• Alcohol poisoning can look like other medical emergencies in older adults, so get urgent help if you are unsure.

Causes

Main causes

• Drinking a large amount of alcohol in a short period (binge drinking)
• Drinking alcohol together with other drugs or medicines
• Drinking games, shots, or consuming alcohol rapidly
• Drinking on an empty stomach, which speeds up absorption

Risk factors

• Being young and inexperienced with alcohol
• Lower body weight
• Drinking without eating
• Mixing alcohol with certain medications, sleeping pills, painkillers, or recreational drugs
• Having a history of heavy drinking or alcohol misuse

When to see a doctor

See a doctor urgently if:

• Call your local emergency number if someone shows signs of severe alcohol poisoning, such as passing out, seizures, or breathing problems.
• Do not wait to see if they improve on their own. Delaying care can be fatal.

Book a routine appointment if:

• If you or someone you know has had a drinking episode and you feel worried about symptoms that are not improving, see a doctor or go to an urgent care clinic.
• If you often drink heavily and want help to cut down, make a routine appointment with your general practice.

Diagnosis

A doctor will ask about what the person drank, how much, and whether they used any other substances. They will examine the person and check their breathing, pulse, temperature, and alertness. The diagnosis is mostly based on what happened and what the doctor sees.

Tests that may be done

• Blood tests to check alcohol level, blood sugar, and electrolyte balance
• Blood tests to check liver and kidney function
• Urine tests to check for other substances
• An ECG (a test of the heart's electrical activity) to check for irregular heart rhythms

What to expect at your appointment

In the emergency department, the person may be closely monitored, given fluids through a drip, and given oxygen if needed. They will be watched until their symptoms improve enough for them to go home safely.

Treatment

There is no medicine that can 'sober up' a person or speed up the removal of alcohol. Treatment is supportive — it helps the body stay safe while it clears the alcohol. The main goals are to protect the airway, support breathing, and prevent complications like choking, dehydration, or hypothermia.

Self-care at home

• If someone is conscious, keep them calm and sitting up or on their side in the recovery position.
• If they are unconscious but breathing, put them in the recovery position and keep them warm.
• Do not leave them alone, even for a minute.
• Do not give them coffee, food, or a cold shower — these do not help and can be dangerous.
• Do not try to make them vomit, as this can cause choking.

Medical treatments

In hospital, treatment includes careful monitoring of breathing and heart rate, oxygen therapy, fluids through a drip to treat dehydration, and medical management of complications such as low blood sugar, seizures, or irregular heart rhythm. Some people may need help with breathing for a while, and severe cases may require intensive care. The treatment is supportive and not a specific medicine.

When is surgery considered?

Surgery is not used to treat alcohol poisoning. In rare cases, surgery may be needed for a separate injury that happened while drinking, but that would be decided by the surgical team.

Living with this condition

Most people who recover from alcohol poisoning can return to their normal life without lasting damage. But having alcohol poisoning is a strong warning sign. It can be helpful to take a honest look at your drinking habits and ask for support if you feel you are drinking too much.

Lifestyle tips

• Stick to national guidelines for low-risk drinking, and have alcohol-free days each week.
• Eat before and while drinking alcohol.
• Drink water in between alcoholic drinks, and slow down.
• Avoid drinking games, shots, or drinking alone.

Diet and exercise

A healthy diet and regular exercise can help your body recover and reduce the risk of long-term health problems linked to alcohol. Always have food in your stomach before drinking, and stay well hydrated.

Mental health and emotional wellbeing

Alcohol poisoning can be a frightening experience and may leave you feeling guilty, embarrassed, anxious, or sad. These feelings are normal. Talking to someone you trust, or speaking with a mental health professional, can help you process what happened and figure out next steps.

Prevention

Yes. Alcohol poisoning is completely preventable. The safest option is to not drink alcohol at all. If you do drink, follow low-risk drinking guidelines, drink slowly, eat before drinking, and never mix alcohol with medications or recreational drugs.

Vaccines

There is no vaccine to prevent alcohol poisoning.

Screening programmes

There is no simple screening test for alcohol poisoning. However, doctors and nurses may ask about your drinking during routine check-ups. Being honest about how much you drink can help them give you the right advice and support.

Complications

If left untreated

• Choking on vomit
• Stopping breathing (respiratory arrest)
• Irregular heartbeat or cardiac arrest
• Seizures
• Hypothermia (dangerously low body temperature)
• Brain damage from lack of oxygen
• Coma and death

Long-term outlook

With early medical care, most people survive alcohol poisoning without permanent harm. However, severe alcohol poisoning can be fatal, even in young people. The best way to stay safe is to never drink to excess, and to seek help if you find yourself drinking heavily. Recovery is possible, and support is available.
