Gambling involves risking something of value (money or possessions) on an event that relies on chance and has a negative expectable value. It includes games of chance and speculating on events such as lottery drawings, horse races, football accumulators and casino games. It also includes placing bets on business or insurance policies. It does not include sports betting, the purchase of stocks or securities or the use of skills to improve chances of winning – for example, knowledge of card playing strategies can help improve one’s odds in certain games.

Some people gamble to relieve stress, for fun or as a social activity. Others find that gambling triggers feelings of euphoria, which is linked to the brain’s reward system. The behavior can be addictive and may result in significant problems for the person involved.

While the number of people with gambling disorders varies, experts agree that many people gamble responsibly. Several factors are associated with the development of gambling disorder, including family and childhood experiences, depression or other mental health conditions, and substance abuse. These factors can make a person more vulnerable to developing an unhealthy relationship with gambling and make recovery more difficult.

Currently, the U.S. Food and Drug Administration does not approve any medications to treat gambling disorders, but psychotherapy is available. Psychotherapy consists of a variety of treatment techniques that take place with a trained, licensed mental health professional, such as a psychologist or clinical social worker. It can help you learn to recognize unhealthy thoughts and behaviors and find other ways to spend your time.
