The relationship between alcohol and mental health is complex. Alcohol consumption can cause alcohol-related mental health conditions such as an alcohol use disorder. It is also associated with a higher likelihood of having other mental health disorders such as anxiety or depression.

Excessive alcohol use can also make it difficult for health professionals to assess and treat existing mental health conditions. Many of the symptoms of alcohol-related mental health disorders are similar to those of general mental health disorders.

In addition, heavy alcohol use can lead to poorer outcomes for people who have existing mental health conditions. For example, people who are depressed and also drink heavily are at greater risk of self-harm and suicide.
