The risks of drinking too much

Regularly drinking more than 14 units a week risks damaging your health.

Fourteen units is equivalent to six pints of average strength beer or 10 small glasses of low strength wine.  

New evidence around the health harms from regular drinking have emerged in recent years.

There is now a better understanding of the link between drinking and some illnesses, including a range of cancers.

The previously held position that some level of alcohol was good for the heart has been revised. It is now thought that the evidence on a protective effect from moderate drinking is less strong than previously thought.

Low risk drinking advice

To reduce the risk of harming your health if you drink most weeks:

  • men and women are advised not to regularly drink more than 14 units a week
  • spread your drinking over three days or more if you drink as much as 14 units a week

If you drink less than 14 units a week, this is considered low risk drinking.

It is called "low risk" rather than "safe" because there is no safe drinking level.

The type of illnesses you can develop after 10 to 20 years of regularly drinking more than 14 units a week include:

The effects of alcohol on your health will depend on how much you drink. The less you drink, the lower the health risks.
