Gambling is an activity where a person bets something of value on an event with the hope of winning. It can involve placing a bet on sports, horse racing, lottery tickets or scratchcards. More recently, technology has enabled gambling to be done from mobile devices such as smartphones and tablets. This makes it very easy to gamble anywhere, and at any time.

While a majority of people who gamble do so responsibly, some people develop problems that can be severe. This is known as ‘problem gambling’ or ‘gambling disorder’ and is recognised by the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition).

Problem gamblers often experience family, work and health problems. They may miss important meetings or deadlines, and their work performance deteriorates. In some cases, they even commit crimes to finance their gambling addictions. They are also at risk of suicide.

A key part of the addiction is a brain response involving dopamine. This is a neurotransmitter that increases the heart rate and makes you feel excited. The brain reacts to both wins and losses, but people with gambling disorders experience more excitement when they win.

There are many things that can be done to help someone with a gambling problem. Firstly, a person with an addiction should talk about it with somebody they trust who won’t judge them. This could be a friend or a counsellor. They should also reduce the number of times they visit casinos or other gambling venues, and try to find new ways to socialise or take up a hobby that doesn’t involve gambling.
