Gambling is a behaviour that involves risking something of value (such as money) on an outcome based on chance. It can be done in a variety of ways, such as buying a lottery ticket, placing a bet on a sports event or using a slot machine. The prize can be anything from a small amount of money to a life-changing jackpot. Gambling can cause harm, and it is important to understand how gambling works in order to gamble responsibly.

The chances of winning in gambling are not guaranteed, and many people find that their gambling becomes harmful to their lives. Gambling can also lead to other problems such as substance abuse, depression or debt. It is important to seek help if you are worried about your own gambling or that of someone close to you.

Why do people gamble? It is often thought that the motivation for gambling is solely about the potential to win money. However, there are many other reasons why people may gamble, such as a desire to change their mood, or the excitement of playing a game that is linked to brain reward systems. The ability to alter one’s mood through gambling can be very powerful.

What is a gambling addiction?

Problem gambling is a serious mental health condition that affects between 0.4% and 1.6% of the population. It is a complex disorder that requires professional treatment. Problem gamblers are at high risk for suicide and other psychiatric disorders.

A person with a gambling addiction may be unable to control their actions and are often ashamed of their behaviour. They may hide their behaviour and lie to others, even about their financial situation. Some people with gambling problems become depressed or suicidal, and others experience relationship difficulties or job loss.

How does gambling work?

The first step in gambling is to decide what you want to bet on. This could be a football match, a horse race or a scratchcard. The choice you make is then matched to ‘odds’, which tell you how much money you can win. The odds are set by betting companies and are published in newspapers and online.

As you start to play, the chances of hitting the jackpot are vanishingly small. You might lose more than you win, but you won’t know until you stop. Trying to get back the money you’ve lost is called chasing losses, and it can lead to bigger losses.

You can prevent gambling problems by only betting with money that you can afford to lose. Never gamble with money that you need for things like rent, food or bills. If you’re concerned that you’re developing a problem with gambling, talk to your doctor or a trained therapist about how to deal with it. They can give you advice and refer you to an appropriate specialist. In severe cases, you might need inpatient treatment or rehab to overcome your addiction. These programs are specialised in treating gambling addiction and are usually located in residential facilities.
