I Want Help With Drugs, Where Do I Start?
Gambling harm is not defined only by how often you gamble or whether you call yourself a “problem gambler”.
Gambling harm is not defined only by how often you gamble or whether you call yourself a “problem gambler”.
NICE uses the broader idea of gambling that harms: gambling of any type or frequency that causes harm, problems or distress to you or people close to you.
That means you can take your concern seriously before gambling has destroyed your finances or relationships.
Look at what gambling is costing beyond the stake
Money is one measure, but not the only one.
Are you losing sleep, hiding transactions, checking bets during work, cancelling plans, borrowing, arguing, becoming distracted around family or spending hours thinking about the next opportunity to gamble?
NICE says assessment should consider mental health, finances, relationships, employment, social functioning and the reasons gambling continues.
Notice secrecy and mental preoccupation
A useful warning sign can be how much space gambling occupies when you are not actually gambling.
You may repeatedly check odds, results or accounts, plan how to find more money, replay losses, hide activity or become irritated when somebody interrupts.
The behaviour can be taking over attention before the financial damage is obvious to anyone else.
Ask what happens after a loss
Do you accept the loss and stop, or immediately feel compelled to recover it?
Trying to win back money can turn one loss into a much larger sequence. It can also change the purpose of gambling from entertainment into an urgent attempt to repair the consequences of previous gambling.
That pattern is explored separately in 23.13.
Use a proper screening tool if you want a clearer picture
NICE recommends encouraging people who are concerned about gambling to use the questionnaire available through the NHS.
A screening result is not a moral judgement. It can help identify the level of harm and whether specialist support would be useful.
Help is available before everything collapses
Current NICE guidance says people experiencing gambling-related harms should be told that support and treatment are available and recovery is possible.
Self-referral through an NHS triage route or the National Gambling Helpline is an option.
You do not have to wait until you have lost a particular amount of money.
