Gambling is the wagering of something of value, with conscious risk and hope of gain, on an uncertain event. It has been shown to have positive effects in some people, such as those who use it for leisure and entertainment, but it is also associated with negative effects like addiction and mental health problems.
Most people who engage in gambling do so without any problem, but a small percentage go on to develop a gambling disorder. These problems can affect their physical and psychological health, cause relationships to break down, interfere with work or study, lead to debt and even homelessness. People with a gambling disorder may have an increased risk of developing other psychiatric disorders, including depression and anxiety.
Many people who gamble do so for entertainment and social activity. For those who do it for a living, it can provide an income and help them meet their financial obligations and needs. It also occupies societal idlers who would otherwise be engaging in criminal and immoral activities such as drug peddling, robberies etc.
Scientists are still trying to understand what drives people to gamble compulsively. Research has found that when people with a gambling disorder are shown images of positive and negative events, their brains react differently than those of non-problem gamblers. This suggests that gambling changes the way the brain responds to reward and excitement. The brain changes can be reversed with treatment. This includes psychotherapy, family therapy and self-help support groups.
