How alcohol affects your body
Many Australians enjoy a drink. In fact,
alcohol
is Australia’s most widely used social drug. Like all
drugs
, alcohol can damage your body, especially if you drink heavily every day or in binges. Even small amounts of alcohol are still linked to the development of certain diseases, including numerous cancers.
Alcohol affects your body
in many ways. Some effects are immediate and last only a while; others accumulate over time and may significantly affect your physical and mental health and quality of life.
How much harm alcohol causes your body depends on how much you drink, your pattern of drinking, and even the quality of the alcohol you drink. Your body size and composition, age, drinking experience,
genetics
, nutritional status, metabolism, and social factors all play a part as well.
The short-term effects of alcohol
The short-term effects of a single occasion of drinking too much alcohol can include:
lowered inhibitions
interpersonal conflict
falls and accidents
altered behaviour – including risky or violent behaviour
hangover
alcohol poisoning.
The severity of the short-term effects of alcohol typically depends on how much a person drinks, but other factors such as hydration and food consumption also play a role.
Hangover
You’ve probably heard of, or perhaps experienced, a ‘hangover’ – a set of unpleasant symptoms that usually follows excessive alcohol intake. Most people can recognise the signs and treat the symptoms themselves.
Generally, the more you drink the higher the likelihood you’ll experience a hangover, but there’s no way to predict how much you may be able to drink and avoid a hangover. Some people can experience a hangover from one drink.
The severity of a hangover often has to do with how your body metabolises alcohol, as when you drink, alcohol triggers a number of reactions in your body. These reactions can contribute to hangover. They include:
frequent urination and dehydration
an inflammatory response from your
immune system
irritation of the stomach lining
a drop in blood sugar
an expansion of
blood vessels
.
Depending on what you drank and how much, your hangover may include these symptoms:
thirst
headache
muscle aches
diarrhoea
nausea
fatigue
weakness
trembling or shaking
rapid heart rate
increased
blood pressure
dry mouth and eyes
poor concentration
increased sensitivity to light and sound
a feeling that the room is spinning, or a sense of dizziness
anxiety
,
depression
, irritability and other mood disturbances
poor, restless or less sleep
.
Most hangovers typically start once your blood alcohol level starts to return closer to zero. Hangovers generally only last up to 24 hours, and go away on their own.
Hangovers are more likely or may be more severe if you:
drink on an empty stomach (so it’s a good idea to eat before and while you drink alcohol)
use other drugs while drinking (smoking nicotine is known to make a hangover worse)
sleep poorly after drinking (alcohol may worsen your sleep which may in turn worsen your hangover)
drink dark coloured alcohols, such as brandy, rum or whiskey.
Pacing yourself (aiming to drink one drink or less every hour), and drinking water between alcoholic drinks may reduce the severity of a hangover.
Hangovers usually pass with time, but these tips may help to ease symptoms:
Sip water or fruit juice to stay hydrated.
Eat something. Plain or bland foods, such as soup or toast, may be easier on a fragile stomach.
Take a pain reliever. (A standard dose of an over-the-counter pain reliever such as paracetamol may ease your headache, but aspirin can irritate your stomach.)
Sleep it off.
If you are regularly experiencing hangovers, or hangovers are affecting your relationships, work or life in general, talk to your doctor about potentially cutting back your drinking.
Alcohol poisoning emergency
Sometimes heavy drinking results in the much more serious effect of alcohol poisoning. This is a life-threatening emergency. Call 000 for emergency care if you see these signs in someone who has been drinking:
confusion
vomiting
seizures
slow breathing (less than eight breaths a minute) or irregular breathing (a gap of more than 10 seconds between breaths)
blue-tinged skin or pale skin
low body temperature (
hypothermia
)
difficulty remaining conscious
passing out (unconsciousness) and can’t be woken.
If someone is unconscious or cannot be woken up, they could be at risk of dying. If you suspect someone has alcohol poisoning – even if you don’t see the signs and symptoms – seek immediate medical attention.
The long-term effects of alcohol
Historically it has been believed that consuming on average more than two standard drinks a day is what can cause many long-term health problems and other harms. Nowadays, current research states that any level of alcohol consumption can pose an increased risk of chronic disease development.
The
World Health Organization
(WHO)
External Link
says alcohol contributes to more than 200 different types of diseases and injury.
Some of the most common alcohol-related harms include:
road and other accidents
domestic and public violence
crime
family breakdown
social dysfunction
cardiovascular disease
cancers
, including of the oral cavity, pharynx, larynx, oesophagus,
liver
, colorectum and
female breast
diabetes
nutrition-related conditions, such as folate deficiency and malnutrition
overweight and obesity
risks to unborn babies
liver diseases
mental health conditions, such as anxiety and depression, and interference with antidepressant
medication
alcohol tolerance and alcohol dependence or addiction
long-term cognitive impairment
self-harm (suicide).
The WHO reports that in 2016, 5.3 per cent of all deaths globally were caused by alcohol consumption. Worldwide, more men die as a result of alcohol consumption than women.
In the long term, alcohol consumption can affect all aspects of a person’s life: their physical and mental health, work, finances and relationships.
What is binge drinking and how does it affect your body?
Generally, binge drinking means drinking heavily over a short period of time with the intention and result of getting immediately and severely intoxicated (drunk).
In the short term, binge drinking may result in a hangover, alcohol poisoning, or any of the other short-term effects of alcohol consumption, such as accidents and violence, discussed above.
In the long term, binge drinking may result in any of the long-term effects of alcohol consumption, such as heart disease, cancer, liver cirrhosis and diabetes.
How to avoid or reduce the effects of alcohol on your body
The best way to avoid the effects of alcohol on your body is to not drink alcohol. This is especially important if you are trying to get pregnant, or you are pregnant or breastfeeding, as there is no safe level of alcohol use that has been identified.
If you choose to drink alcohol, low level drinking is better for your body than heavy drinking or binge drinking.
Australia’s
national guidelines to reduce health risks from drinking
alcohol
External Link
from the National Health and Medical Research Council say that the lifetime risk of harm from drinking alcohol increases the more you drink. For healthy men and women, they advise:
Drinking no more than 10 standard drinks per week reduces the lifetime risk of harm from alcohol-related disease or injury.
Drinking no more than four standard drinks on any one day reduces the risk of alcohol-related injury arising from that occasion.
The less you choose to drink, the lower your risk of alcohol-related harm. For some people not drinking at all is the safest option.

It is important to monitor your alcohol consumption as part of a healthy diet. Alcohol consumption has the potential to cause weight gain and obesity, depending on how much someone drinks, the type of drink consumed, as well as the makeup of each individual and a number of other interpersonal factors.
