According to the DSM-5, gambling disorder is characterized by persistent and recurrent problematic gambling behavior that leads to significant distress or impairment. To meet the criteria for gambling disorder, an individual must exhibit at least four of the following symptoms within a 12-month period:

Needing to gamble with increasing amounts of money to achieve the desired excitement.
Being restless or irritable when attempting to cut down or stop gambling.
Making repeated unsuccessful efforts to control, cut back, or stop gambling.
Being preoccupied with gambling (e.g., constantly thinking about past gambling experiences, planning the next gambling session, or devising ways to obtain money to gamble).
Often gambling when feeling distressed (e.g., helpless, guilty, anxious, or depressed).
After losing money gambling, often returning another day to get even (“chasing” one’s losses).
Lying to conceal the extent of gambling involvement.
Jeopardizing or losing significant relationships, jobs, education, or career opportunities because of gambling.
Relying on others to provide money to relieve desperate financial situations caused by gambling.
These symptoms are indicators of gambling disorder, but a diagnosis requires professional evaluation and assessment by a qualified mental health professional.
