Gambling involves risking money or something of value on an event that has some element of randomness and chance. It can be done by placing a bet on the outcome of a game or activity such as a poker hand, a dice roll, a football accumulator or a horse race. It can also involve the wagering of materials that have a monetary value such as marbles, coins or collectible trading cards. There is an element of skill in some games such as card games or dice games but the main consideration when defining gambling is the presence of risk and chance.

There are many reasons why people gamble. Some do it to relax or enjoy themselves. Others do it to try and win big prizes. There are also those who do it for financial reasons, to change their lifestyle or even to get out of debt. Problem gambling can cause serious harm to physical and mental health, relationships, work or study performance and can lead to homelessness and bankruptcy. It can also have a negative impact on the lives of family and friends.

Many organisations provide help, support and counselling for people with problems with gambling. They can give you the tools to control your gambling and even stop it altogether. Some also offer residential treatment and rehab programmes for those who need round the clock support.

There is a link between mood disorders and gambling. Depression, anxiety or stress can all trigger gambling problems and make them worse. Similarly, compulsive gambling can mask underlying mood issues and become a way to escape from reality. This can create a vicious cycle whereby the person starts to gamble to feel better and then becomes more stressed as they spend more money.

While most people who gamble do so for fun, some find it difficult to stop and can become addicted to the thrill of winning and losing. The behaviour may be triggered by social, financial or emotional pressures, or by alcohol or drugs. It is more common in men than in women and can start during adolescence or in adulthood.

Those who have a gambling disorder often have difficulty recognizing that they have a problem and may hide their gambling or lie to family and friends. They may also spend large amounts of time gambling or have a high level of credit card debt. There are several types of therapy that can help people with gambling disorders, including cognitive behavioral therapy (CBT), psychodynamic therapy and group therapy. There is also evidence that a combination of therapies can be effective for some people. However, only one in ten people with gambling problems seek treatment.
