What is it?
Alcohol (chemical name ethyl alcohol or ethanol) is a liquid made from sugars by the action of yeast. The products may be drunk in their original form (for example, beer and wines), or after strengthening (for example, sherry, port and spirits). Alcohol avoidance involves cutting down or stopping drinking.
How does it work?
Heavy drinkers, and especially people addicted to alcohol, are more likely to suffer from depression. There are two main ways in which cutting out alcohol may help with depression:
- It is thought that heavy drinking can lead directly to depression and so cutting out alcohol will reverse this effect.
- It can help by reducing problems caused by drinking, such as money problems, problems at work and relationship problems.
Is it effective?
A systematic review of 15 studies found that people who have an alcohol use disorder are twice as likely to have major depression compared to those who do not have an alcohol use disorder. However, more research is needed to determine exactly how these two disorders are linked. It could be that having an alcohol use disorder makes you more likely to develop depression, or that those who already have depression are more likely to develop an alcohol use disorder. For people who have an alcohol use disorder, stopping drinking often results in an improvement in their depression symptoms.
A large Australian survey found that for people who do not have an alcohol use disorder, there seems to be no link between alcohol use and depression. That is, people who do not drink, or who have cut back their use, have about the same risk of developing depression as people who drink regularly.
Are there any disadvantages?
For people who are heavy drinkers, giving up alcohol can produce withdrawal effects which can be serious. If you think you may have an alcohol use disorder and you would like to stop drinking alcohol, you should talk to your doctor about how to do this safely.
Where do you get it?
People can cut down on their drinking without outside help, but there are also services and organisations that can help. Look at the Drug & Alcohol Counselling section of the Yellow Pages, or you can visit the Drinkwise Australia website for a list of support services. People with long-term drinking problems and those who are dependent on alcohol are more likely to need expert help to reduce their drinking.
If you would like to assess your current drinking habits, you can complete an online risk assessment tool provided by the Mental Health Commission in Western Australia.
For the general population there is no evidence that restricting alcohol intake is beneficial for depression. For heavy drinkers or those with alcohol use disorder, alcohol avoidance may improve their depression symptoms.
