Facts
about Alcohol
How can you tell if you’re a binge drinker?
Even
if you don't drink alcohol every day, you could be a binge
drinker if you regularly drink:
- to get drunk
- more than the recommended daily
guidelines in a single session quickly.
If
you find it hard to stop drinking once you have started, you
could also have a problem with binge drinking and possibly
alcohol dependence.
Government guidelines on alcohol
units
The
Government's guidelines say that a man should not regularly
drink more than 3-4 alcohol units a day and a woman
should not regularly exceed 2-3 units a day.
Calories in alcohol
The
unit calculator shows you the number of calories in the alcohol
you have consumed. Many people are very surprised by the number
of calories in alcoholic drinks- it is easy to make the mistake
of thinking that drinks are calorie-free.
What is an alcohol unit?
One
alcohol unit is measured as 10ml or 8g of pure alcohol. This
equals one 25ml single measure of whisky (ABV 40%), or a third
of a pint of beer (ABV 5-6%) or half a standard (175ml) glass of
red wine (ABV 12%).

Can’t find your drink?
Work
out your alcohol units for yourself with this handy sum:
Strength (ABV) x Volume (ml) ÷ 1000 = No. of units.
E.g. Pint of
Stella - 5.2 x 568 ÷ 1000 = 2.95
Drink
enough alcohol, and you are likely to damage your liver. This
can happen quickly or over a longer period. Increasing numbers
of people in the
UK
are being hospitalised and dying, as a result of liver disease
associated with alcohol.
Up
to one in three adults drinks enough alcohol to create a risk of
developing alcohol-related liver disease.
Facts
and Figures
A
major risk factor for liver disease is alcohol consumption, but
the evidence is unclear as to the precise relationship between
the amount of alcohol you drink and the incidence of liver
disease.
For
example, an Italian study found that liver disease risk
increased after consuming 30g (about 3.8 units) of alcohol per
day and that after this risk increased with the amount of
alcohol consumed (1). Whereas a Chinese study found
that 20g of alcohol (about 2.5 units) per day doubled the risk
of liver disease, but thereafter found the risk did not increase
with each additional dose. (2).
A
number of studies suggest that consuming enough alcohol might
trigger the disease process, but that higher levels of alcohol
consumption do not have any additional impact (a relationship
known as a threshold effect).
Other
risk factors include:
- Alcohol dependence: However,
around 8 in 10 people with alcohol dependence will not have
liver damage.(3)
- Gender:
Women are more susceptible to alcohol-related liver damage
than men, with one study suggesting the risk is almost 50%
higher (4).
- Body mass index: Being overweight or obese
increases the risk of alcohol-related liver disease.
- Race:
Some data suggests people of African origin are more
susceptible than Caucasians (5).
- Genetic predisposition:
There’s no clear data on this, but the fact that only a
minority of heavy drinkers develop liver disease suggests a
genetic predisposing factor (6).
- Pattern of drinking:
Drinking alcohol only at meal times appears to carry a lower
risk of alcohol-related liver disease than other patterns of
alcohol consumption (1).
Progression
There
are two patterns of liver disease, acute (known as acute
alcoholic hepatitis) and chronic, which reflect whether it
develops over a matter of months or years respectively.
Chronic
Liver Disease
There
are four stages of chronic liver disease.
1.
The commonest and mildest form of liver damage is a ‘fatty’
liver. This can be identified by blood tests, and is
reversible with abstinence from alcohol.
2.
The next step cannot be identified by blood tests, but a liver
biopsy will show inflammation in addition to the excess fat.
This is called steatohepatitis. In severe cases, jaundice
may develop. A diagnosis of acute alcoholic hepatitis can
then be made (see below).
3.
At the next stage, fibrosis (scar tissue) is present.
Again, this cannot be detected by blood tests or routine scans.
4.
Cirrhosis occurs when the fibrosis reaches the stage when
the normally soft liver is divided into thousands of pea-sized
pockets of liver tissue, wrapped in fibrosis. Once cirrhosis
develops, the prognosis partly depends on whether or not you
continue drinking. People with compensated cirrhosis – meaning
they have no symptoms – and who then stop drinking, have an
80% chance of being alive after 10 years.
The
majority of those with decompensated cirrhosis – displaying
symptoms – will die within three years.
Acute
Liver Disease- known as Acute Alcoholic Hepatitis.
This
type of liver disease is caused by heavy drinking over a period
of months. This is the pattern that is likely to occur when
young people get liver disease, although older people who drink
excessively later in life are also susceptible. It is
potentially reversible with no long-term effects if you recover
and stop drinking alcohol completely.
However,
70-90% of patients with acute alcoholic hepatitis – likely to
be those who have been drinking for longer, and therefore
unlikely to be young people - will have cirrhosis (see above).
Jaundice is the usual first symptom. In hospitalised cases,
there’s a mortality rate of around 50% associated with acute
alcoholic hepatitis. Liver transplants are usually not an
option, partly because of the history of recent alcohol abuse.
From
the second you take your first sip, alcohol starts affecting
your body and mind. After one or two drinks you may start
feeling more sociable, but drink too much and basic human
functions, such as walking and talking become much harder. You
might also start saying things you don’t mean and behaving out
of character. Some of alcohol’s effects disappear overnight
– while others can stay with you a lot longer, or indeed
become permanent.
Diseases
and cancers
Experts
estimate alcohol is responsible for at least 33,000 deaths in
the
UK
each year. While rates of liver disease are falling in the rest
of Europe, they are rising in the
UK
. A 2006 Lancet study found that liver cirrhosis death rates are
already around twice as high in
Scotland
as they are in other European countries.
Liver
disease used to affect mainly drinkers in middle age, but now
sufferers are getting younger. Up to one in three adults in the
UK
drinks enough alcohol to be at risk of developing
alcohol-related liver disease.
Alcohol
misuse is an important factor in a number of cancers, including
liver cancer and mouth cancer, both of which are on the
increase. Alcohol is second only to smoking as a risk factor for
oral and digestive tract cancers.
Evidence
suggests that this is because alcohol breaks down into a
substance called acetaldehyde, which can bind to proteins in the
mouth. This can trigger an inflammatory response from the body
– in the most severe cases, cancerous cells can develop.
Chronic
pancreatitis is another disease associated with heavy drinking.
It’s caused when your pancreas becomes inflamed and cells
become damaged. Diabetes is a common side effect of chronic
pancreatitis. There’s evidence that heavy drinking can reduce
the body’s sensitivity to insulin, which can trigger type 2
diabetes.
While
studies suggesting that alcohol can help heart disease often hit
the headlines, the reality is that the jury’s still out on the
extent of any benefits. And it is clear that any benefits which
there may be are limited to very low levels of consumption –
probably no more than 1 unit alcohol per day.
Mental
health
Alcohol
alters the brain’s chemistry and increases the risk of
depression. It is often associated with a range of mental health
problems A recent British survey found that people suffering
from anxiety or depression were twice as likely to be heavy or
problem drinkers.
Extreme
levels of drinking (defined as more than 30 units per day for
several weeks) can occasionally cause ‘psychosis’, a severe
mental illness where hallucinations and delusions of persecution
develop. Psychotic symptoms can also occur when very heavy
drinkers suddenly stop drinking and develop a condition known as
‘delirium tremens’.
Heavy
drinking often leads to work and family problems, which in turn
can lead to isolation and depression. For heavy drinkers who
drink daily and become dependent on alcohol, there can be
withdrawal symptoms (nervousness, tremors, palpitations) which
resemble severe anxiety, and may even cause phobias, such as a
fear of going out.
Appearance
If
you’re trying to watch your waistline, drinking too much
alcohol can be disastrous! Research from the Department of
Health reveals that a man drinking five pints a week consumes
the same number of calories as someone getting through 221
doughnuts a year.
Drinking
too much alcohol isn’t great news for your skin either. As
well as causing bloating and dark circles under your eyes,
alcohol dries out your skin and can lead to wrinkles and
premature aging. If you drink heavily you may develop acne
rosacea, a skin disorder that starts with a tendency to blush
and flush easily and can progress to facial disfiguration, a
condition known as rhinophyma.
Dependence
If
you drink large quantities of alcohol on a regular basis you run
the risk of becoming addicted. Experts estimate that one in 17
people (6.4%) in
Great Britain
depend on alcohol to get through the day. This can have serious
effects on their families, friends and partners, as well as
their mental health.
Alcohol
poisoning
Between
2007 and 2008 more than 30,000 people were admitted to hospital
with alcohol poisoning. In the worst cases alcohol poisoning can
cause lung damage (as you inhale your own vomit) and even lead
to a heart attack.
Many
traditional ‘cures’, such as drinking black coffee; just
don’t work – or even make things worse.
The
morning after
If
you’ve drunk heavily the night before, you’ll almost
certainly wake up with a hangover. Alcohol irritates the
stomach, so heavy drinking can cause sickness and nausea and
sometimes diarrhoea. Alcohol also has a dehydrating effect,
which is one reason why excessive drinking can lead to a
thumping headache the morning after.
Alcohol
is a depressant, not a stimulant. This means that it slows down
the brain and the central nervous system’s processes. You may
wonder what you did the night before, feel guilty, low or
lethargic.
Women
and alcohol
These
days women are just as likely as men to make alcohol a major
part of their social lives. The problem is that many women
regularly drink more than the Government’s daily recommended
guidelines of 2-3 alcohol units, with around one in 14 drinking
alcohol every day.
Women
respond to alcohol differently from men, so the recommended
levels are lower than for their male counterparts.
Recent
research such as
Oxford
University
’s Million Women Study highlight the links between moderate
drinking and increased risks of breast cancer.
Alcohol
is a poison and too much of it can kill you.
Acute alcohol poisoning is usually a result of binge
drinking. Your body can process about one unit of alcohol an
hour. If you drink a lot in a short space of time, the amount of
alcohol in your bloodstream (blood alcohol concentration or BAC)
may become dangerously high.
This can stop your body from working properly. In extreme cases,
alcohol poisoning could stop you breathing, your heart
could stop beating or you could choke on your own vomit.
Many of the traditional ‘cures’ for alcohol poisoning –
giving someone black coffee, making them sick, leaving them to
sleep it off – can do more harm than good. By recognising the
signs of alcohol poisoning and knowing how to respond, you could
save someone’s life.
Alcohol
poisoning: Facts and figures
- Alcohol is a depressant, which
means it slows down your brain’s functions. You might lose
your inhibitions and your sense of balance. But it also
affects the nerves that control your heartbeat, breathing
and gag reflex (which is what stops you choking).
- Alcohol irritates the stomach,
which causes vomiting – dangerous if somebody’s gag
reflex isn’t working properly. People die from choking or
accidentally inhaling vomit into their lungs.
- Someone’s BAC continues to rise
even after they’ve stopped drinking, as alcohol in the
digestive system will continue to be absorbed into the
bloodstream. This means you should never leave someone to
‘sleep it off’, as their condition could still be
getting worse.
- There is no minimum dose for
acute alcohol poisoning to take effect – it depends on
your age, sex, size, weight, how fast you’ve been
drinking, how much you’ve eaten, your general health,
other drugs you might have taken…
- More than 30,000 people were
admitted to hospital with alcohol poisoning in
England
in 2007-08 (13,400 men and 16,700 women) – that’s more
than 500 every week.(1)
- 157 people died from accidental
alcohol poisoning in
England
in 2007.(2)
Progression
of alcohol poisoning
Be
alert for signs that somebody has progressed from being stupidly
drunk to dangerously intoxicated:
- Confusion
- Loss of coordination
- Vomiting
- Seizures
- Irregular or slow breathing (less
than eight breaths a minute)
- Blue-tinged or pale skin
- Low body temperature
(hypothermia)
- Stupor (being conscious but
unresponsive)
- Unconsciousness (passing out)
In
the worst cases, alcohol poisoning can lead to comas, brain
damage and even death. After an alcohol overdose, you could:
- Choke on your vomit
- Stop breathing
- Have a heart attack
- Inhale vomit, leading to fatal
lung damage
- Experience severe dehydration,
which can cause permanent brain damage in extreme cases
- Get hypothermia
- Suffer seizures because of
lowered blood sugar levels.
Alcohol
poisoning: Getting advice and help
Someone who’s suffering from acute alcohol poisoning will be
in no state to help themselves, so it’s important to look out
for your friends.
What to do if someone is showing signs of alcohol poisoning:
DO
- Try to keep them sitting up and
awake
- Give them water if they’re able
to drink it
- Lie them on their side in the
recovery position if they’ve passed out. Check they’re
breathing properly
- Keep them warm
- Stay with them and monitor their
symptoms.
DON’T
- Give them coffee – it will make
them more dehydrated
- Leave them alone, even if
they’re asleep, or leave them lying on their back
- Walk them around
- Put them under a cold shower
- Let them drink any more alcohol.
DON’T
wait for all the symptoms to be present before getting help.
DO DIAL 999 to call an ambulance if you’re in any doubt.
Hospital
treatments for acute alcohol poisoning
Every
weekend, hundreds of people are taken into hospital with acute
alcohol poisoning. In less severe cases, the medical staff will
monitor them closely until they’re in a fit state to be taken
home. This may involve an overnight stay.
In
more severe cases, the medical staff may:
- Insert a tube into their trachea
to help them breathe
- Fit an intravenous drip to top-up
the body’s water, blood sugar and vitamin levels
- Fit a catheter (a tube that goes
up the urethra, so the bladder empties straight into a bag)
- Pump the stomach by flushing
fluids through a tube inserted into the nose or mouth.
Around
40% of patients admitted to A&E are diagnosed with
alcohol-related injuries or illnesses, many of which result from
binge drinking.
What
is binge drinking?
The
NHS definition of binge drinking is drinking heavily in a short
space of time to get drunk or feel the effects of alcohol.
The
amount of alcohol someone needs to drink in a session for it to
be classed as ‘bingeing’ is less clearly defined but the
marker used by the NHS and National Office of Statistics is
drinking more than double the daily recommended units of alcohol
in one session.
The
Government guidelines state that men should not regularly drink
more than three to four units a day, and women should not
regularly exceed more than two to three units daily.
Binge
drinking
for men, therefore, is drinking more than eight units of alcohol
– or about three pints of strong beer. For women, it’s
drinking more than six units of alcohol, equivalent to two large
glasses of wine.
What’s
the difference between drinking normally and binge drinking?
Two
large glasses of wine may not seem like very much. But drinking
six units of alcohol in a short space of time – an hour, say
– will raise your blood alcohol concentration (BAC) and could
make you drunk very quickly. Drinking the same amount over
several hours, and accompanied by food for example, will not
have the same effect on your BAC.
What
are the effects of binge drinking?
Some
studies show that drinking a large amount of alcohol over a
short period of time may be significantly worse for your health
than frequently drinking small quantities.
Getting
very drunk can affect your physical and mental health:
- Accidents and falls are common
because being drunk affects your balance and co-ordination.
You’re also more likely to suffer head, hand and facial
injuries. Binge drinking has also been linked to self-harm .
- In extreme cases, you could die.
Overdosing on alcohol can stop you breathing or stop your
heart, or you could choke on your vomit.
- Nearly a third (29%) of alcohol
related deaths are a result of alcohol related accidents.
These deaths are more common among 16–34-year-olds.
- Binge drinking can affect your
mood and your memory and in the longer term can lead to
serious mental health problems.
More
commonly, binge drinking can lead to anti-social, aggressive and
violent behaviour.
Alcohol
is a factor in:
- One in three (30%) sexual
offences
- One in three (33%) burglaries
- One in two (50%) street crimes.
Binge
drinking is most common among 16–24-year-olds , and is more
common among men than women. The General Lifestyle Survey 2008
showed that 21% of men and 14% of women drank more than double
their recommended units on at least one day in the previous
week. However, in the last decade binge drinking among young
British women has increased rapidly.
And binge drinking when you’re young can become a habit.
Studies have shown that those who drink a lot in their teens and
early 20s are up to twice as likely as light drinkers to be
binge drinking 25 years later.
Fatal alcohol syndrome (FAS) is a pattern of mental and physical defects which
develops in some unborn babies when the mother drinks excessive
alcohol during pregnancy. The
ingestion of alcohol does not always result in FAS, but no
amount of alcohol whatsoever is proven safe for consumption
during pregnancy. The current recommendation of both the
Department of Health is not to drink alcohol at all during
pregnancy.
Alcohol crosses the placental barrier and can stunt fetal growth and weight,
create distinctive facial stigmata, damage neurons and the
structure of the brain, and cause other physical, mental, or
behavioral problems. Surveys found that in the
United States
, 10–15% of pregnant women report having recently used
alcohol, and up to 30% use alcohol at some point during
pregnancy. The main effect of FAS is permanent central nervous
system damage, especially to the brain. Developing brain cells
and structures are underdeveloped or malformed by prenatal
alcohol exposure, often creating an array of primary cognitive
and functional disabilities (including poor memory, attention
deficits, impulsive behavior, and poor cause-effect reasoning)
as well as secondary disabilities (for example, mental health
problems, and drug addiction) The risk of brain damage exists
during each trimester, since the fetal brain develops throughout
the entire pregnancy.
Fatal alcohol exposure is the leading known cause of mental retardation in
the Western world. In
Europe
the FAS prevalence rate is estimated to be nearly one in every
100 live births
Korsakoff's syndrome is a brain disorder usually associated with heavy
alcohol consumption over a long period. Historically it has also
been called 'Korsakoff's psychosis', although this can be
confusing, as there are no true psychotic symptoms in the
medical sense. Sometimes it is referred to as 'alcohol amnestic
syndrome' − 'amnestic' meaning loss of memory −
although in rare cases alcohol is not the cause. Although
Korsakoff's syndrome is not strictly speaking a dementia, people
with the condition experience loss of short-term memory. This
factsheet outlines the causes, symptoms and treatment of the
syndrome.
What causes Korsakoff's syndrome?
Korsakoff's syndrome is caused by lack of thiamine (vitamin B1), which
affects the brain and nervous system. Thiamine deficiency is
often seen in people who consume excessive amounts of alcohol.
This is because:
- Many
heavy drinkers have poor eating habits. Their nutrition is
inadequate, and does not contain essential vitamins.
- Alcohol
can inflame the stomach lining and impede the body's ability
to absorb the key vitamins it receives.
Korsakoff's syndrome may also occur in other conditions where there is
severe malnutrition, but this is extremely rare in the
UK
.
Korsakoff's syndrome is part of
Wernicke-Korsakoff syndrome, which consists of two separate but
related stages: Wernicke's encephalopathy and Korsakoff's
syndrome. However, not all cases of Korsakoff's syndrome are
preceded by an episode of Wernicke's.
The
pancreas is a gland that produces enzymes which help with
digestion, and hormones, such as insulin and glucagon, which
control blood sugar levels.
You
get pancreatitis when your pancreas becomes inflamed, and its
cells are damaged. There are two types of pancreatitis, acute
and chronic. Both are often caused by heavy drinking.
Facts
and figures
Acute
pancreatitis is most commonly caused by a bout of heavy drinking
or by gallstones.
The
main symptom of acute pancreatitis is abdominal pain, felt just
behind the ribs and spreading through to your back. The pain,
which usually comes on over about an hour, can be severe. Other
symptoms include nausea, vomiting and fever.
Most
cases come on quickly and usually go away quickly, leaving no
permanent damage.
However,
one in five cases are severe. Other organs can be damaged by
pancreatic enzymes getting into your bloodstream during an
attack. This can lead to serious illness, such as kidney or
respiratory failure, and can be fatal. About 25% of people who
develop severe acute pancreatitis die.
Each
year, in the
UK
, between five and 80 people in every 100,000 are diagnosed with
acute pancreatitis.
Chronic
pancreatitis is when your pancreas is constantly inflamed. Heavy
drinking, usually over a period of 10 years or more, is the
cause of about eight out of 10 cases of chronic pancreatitis.
However, the condition can also be hereditary. Men between the
ages of 40 and 50 are most commonly affected.
The
main symptom of chronic pancreatitis is also abdominal pain that
is felt behind the ribs and goes all the way through to your
back. It is a recurrent pain, which can be mild initially, but
can become severe for some people. Weight loss is common for
people with chronic pancreatitis.
Approximately
three to nine in every 100,000 people in the
UK
develop chronic pancreatitis every year.
How
does alcohol cause pancreatitis?
A
strong link exists between heavy drinking and pancreatitis.
Alcohol can trigger the pancreas to become inflamed and its
cells become damaged, impeding its digestive function and
causing pain.
However, the exact process through which alcohol causes both the
acute and chronic versions of the disease is unclear.
• A
University
of
Liverpool
study concluded that acute pancreatitis occurs because alcohol
acts as a stimulant for the pancreas to produce fatty acids and
other fatty substances. These substances can destroy cells and
stop energy production in the pancreas.
