Gambling is a form of risk-taking and involves betting money or other belongings on an event with an element of chance. There are many different types of gambling, including gaming (card games, fruit machines and video-draw poker), betting on horse races or football accumulators, lotteries and gambling on the stock market.

People often gamble for fun, or as a way to socialise with others. But for some people, gambling can become an addiction that is difficult to control or stop. This is called gambling disorder and can have serious consequences for the gambler, their family and friends.

There are many ways to find help if you have problems with gambling. Some services offer support groups and counselling. They can help you to find a way of controlling or abstaining from gambling altogether.

Those who have a problem with gambling can also contact a local or national helpline to find support and advice. There are also many self-help support groups for families and individuals with a problem with gambling.

A person with a gambling problem is considered to be a pathological gambler when they have an uncontrolled obsession with gambling that interferes with their work, relationships or social life. They can lose large amounts of money and become financially ruined. They may even die from their gambling habits.

Most people have a small flutter from time to time, but if it becomes a problem, seek professional help. The aim is to help you manage your gambling so it doesn’t affect your day-to-day life.

The behaviour of gambling is closely linked with impulsiveness, sensation seeking and arousal. It is thought that the brain reacts to gambling by stimulating certain areas of the brain, and then releasing chemicals such as dopamine, epinephrine, and serotonin. These chemicals are thought to trigger a reaction in the brain that causes a feeling of excitement, or euphoria.

Sensation and novelty-seeking is the main driver of this behaviour. The brain is constantly trying to satisfy its craving for these feelings, which can lead to an urge to spend money on gambling.

Research has shown that people who have a problem with gambling are likely to be very impulsive and have poor impulse control. They are also more likely to have high levels of arousal, anxiety and negative emotions.

These characteristics are common in problem gamblers and may make them more likely to lose their money or their jobs or to be a target of gangs or other criminal organisations. They can also lead to a range of health risks, such as heart disease and cancer.

This is why it is important to know what signs to look for when a person starts to gamble more than they should. Some of these signs include:

In recent years, a number of researchers have begun to study the role of impulse control in the development of pathological gambling. These studies have found that impulsivity is strongly associated with the development of gambling and its progression.
