'Social drinking': the hidden risks


NHS




If you think only alcoholics and binge drinkers are putting their health at risk, think again.
Many people who see themselves as "social drinkers" are at risk of developing long-term health conditions because of the amount they regularly drink.
Most drinkers are unaware that regularly drinking more than the limits advised by the NHS can lead to a wide range of long-term health problems, including cancers, strokes and heart attacks.
More than 55% of people questioned in a YouGov poll thought that alcohol only damages your health if you regularly get drunk or binge drink.
The 2010 survey of 2,000 adults also found that 83% believed that regularly drinking more than the recommended daily limits didn’t put their long-term health at risk.
The survey suggests that 7.5 million people might be unaware of the damage their drinking could be causing.

The NHS recommends:

  • Men should not regularly drink more than 3-4 units of alcohol a day
  • Women should not regularly drink more than 2-3 units a day
  • If you've had a heavy drinking session, avoid alcohol for 48 hours
    "Regularly" means drinking this amount every day or most days of the week.
    Read about the risks of drinking too much to find out how your drinking habits may be affecting your health.

    Over the limit

    More than 9 million people in England drink more than the recommended daily limits. About 15,000 people in England die from alcohol-related causes each year. About 32% of these deaths are from liver disease, 21% from cancer and 17% from cardiovascular illnesses, such as heart disease and strokes.
    Typically, longer-term alcohol-related illness or death affect older people who drink more than the recommended daily limits and consider themselves to be "social drinkers".
    Professor Nigel Heaton is a liver transplant consultant at King’s College Hospital, London. He says people who believe that drinking above the lower-risk guidelines is just normal social drinking may be raising their risk of developing alcohol-related illnesses.
    “Some people think it’s natural to have a bottle of wine a night,” he says. “It seems respectable because you’re drinking with food and it’s not associated with any drunken behaviour or even feeling drunk.
    "But if it happens regularly, you may have problems later on. Most of us believe that people with alcoholic liver disease are alcoholics. We often think, 'I’m not an alcoholic so I can’t get liver disease'.
    “You may not be an alcoholic, but if the overall amount of alcohol you drink regularly exceeds the lower-risk guidelines, it may still cause serious harm.”
    Track your drinking
    To find out if you need to cut down, take the drinking self-assessment. It’ll help you assess the effects of your drinking. If it suggests that you’re drinking too much, you’ll get advice on how to cut down.
    Monitor your drinking with the desktop alcohol tracker and drinks tracker for iPhone. This calculates the units of alcohol in your drinks, and it helps you work out whether you should cut down.
    Because drinks come in all shapes and sizes, it can be hard to keep track of your units. Use the unit calculator to add them up and help you monitor the amount you drink.
    Research suggests many people underestimate how much alcohol they drink. Download a drinks diary (PDF, 697kb) to track your drinking over a week.
