Gambling involves betting something of value on an event that is based on chance. Unlike sports betting, there is no strategy involved in gambling. Some people can develop a problem with gambling. This is called pathological gambling and it is recognised in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition).
A large proportion of people who gamble do so without any problems. But a small proportion of those who start gambling go on to develop problem gambling, which is defined as a recurrent pattern of gambling that causes significant distress or impairment.
The behaviour of some people who are addicted to gambling is similar to the behaviour of some people who are addicted to drugs or alcohol. This is because gambling is a form of addiction and affects the brain in the same way as other addictive substances or drugs. People with this type of addiction are often predisposed to impulsivity and may have difficulty controlling their impulses, particularly when they feel excited or aroused.
Several factors can trigger problem gambling, including mood disorders like depression or anxiety. These conditions can also be made worse by compulsive gambling. Many organisations offer help, advice and support for people who have a gambling problem.
If someone is a secretive or deceptive gambler, this can hurt their family and friends. They may hide their gambling activity from their loved ones or lie about how much they’re spending. They might even try to win back lost money by increasing their bets.
