Warning Signs of Problem Gambling: What to Look For

Gambling harm rarely arrives overnight. More often it builds gradually, with small changes that are easy to explain away. Recognising those changes — in yourself or in someone you care about — makes it far easier to act before the consequences become serious.

This page sets out the most common warning signs, grouped by type, along with practical next steps. It is not a diagnostic checklist, and no single sign proves that someone has a gambling problem. It is a prompt for honest reflection.

Behavioural signs

These are changes in how and when someone gambles.

• Chasing losses — gambling again, often with higher stakes, to win back money already lost. This is one of the most reliable early indicators of harm.
• Spending more time or money than intended, repeatedly, despite setting limits.
• Needing to bet more to feel the same excitement.
• Failed attempts to cut down or stop, or feeling restless and irritable when trying.
• Gambling to escape stress, boredom, loneliness, low mood or other problems.
• Preoccupation — frequently thinking about past bets, planning the next one or working out how to get money to gamble.
• Opening multiple accounts or moving between operators after hitting a limit or being excluded.
• Gambling at unusual times, such as late at night or during work.

Financial signs

Money is often where harm becomes visible first.

• Using money meant for rent, bills, food or childcare to gamble.
• Borrowing from friends, family, payday lenders or credit to fund gambling or cover losses.
• Unexplained debts, missed payments, or bank statements that are hidden or “lost”.
• Selling possessions, or money or valuables going missing at home.
• Regularly running out of money before payday.
• Treating gambling as a way to solve financial problems.

Emotional and psychological signs

• Anxiety, low mood, guilt or shame linked to gambling.
• Irritability, especially when unable to gamble or when questioned about it.
• Mood swings that track wins and losses.
• Difficulty sleeping, or lying awake thinking about gambling or debts.
• Feelings of hopelessness or being trapped.

Gambling harm and mental health difficulties are closely linked and can feed each other. Our article on gambling and mental health covers this in more depth.

Signs in relationships, work and study

• Secrecy and lying about where time or money has gone.
• Arguments about money or gambling at home.
• Withdrawing from family, friends or hobbies.
• Missing work, falling behind at college, or being distracted and tired.
• Becoming defensive or angry when gambling is mentioned.

Family members and friends often notice these changes before the person gambling acknowledges them. If that is your situation, see how to talk to someone about their gambling.

Signs specific to online gambling

Online gambling is available around the clock on a phone, which removes many natural pauses. Watch for:

• Constant checking of betting apps or live scores.
• Gambling in bed, in the bathroom or in other private moments.
• Multiple deposit notifications in a short period.
• Repeatedly reversing withdrawals to keep playing.
• Using several payment methods or e-wallets to get around limits.

Checking where you stand

Validated screening questionnaires can help you reflect on your gambling more objectively:

• The Problem Gambling Severity Index (PGSI) asks nine questions about the past 12 months and is widely used in national surveys.
• The Lie/Bet screen uses just two questions as a quick first check.
• The DSM-5 checklist walks through the nine criteria clinicians use when assessing gambling disorder.

These tools are not diagnoses. A low score does not mean you should ignore something that is worrying you, and a high score is a reason to seek a proper conversation with a professional, not a verdict on who you are. You can learn more about the clinical side in gambling disorder explained.

Signs that often get missed

Some indicators are easy to overlook because they look like ordinary behaviour. Watch for gambling being used as a reward or as a way to “switch off” after work, a growing interest in odds and tipsters, describing gambling as an investment or second income, and keeping a mental tally of wins while forgetting losses. On their own these are not proof of harm, but they can signal a shift in how gambling fits into someone’s life.

What to do if you recognise these signs

If several of these signs feel familiar, there are practical steps you can take today:

1. Pause. Use a time-out or cooling-off tool on your accounts, or remove betting apps from your phone.
2. Put barriers in place. Consider self-exclusion, blocking software and a bank gambling block.
3. Talk to someone. A helpline, peer-support group or your doctor can help you think through options. Our help directory lists services by country.
4. Get a clear picture of money. Write down debts and essential outgoings. Free, confidential debt advice is available in many countries.
5. Be kind to yourself. Shame keeps people stuck. Recognising a problem is a strength, not a weakness.

If you are in crisis

Gambling harm can sometimes lead to feelings of despair or thoughts of ending your life. If you are in crisis, feel unable to keep yourself safe, or are thinking about suicide, please contact your local emergency services immediately. If you are worried about someone else’s immediate safety, do the same. You do not need to be sure; it is always right to ask for help.

The bottom line

Warning signs are not labels. They are signals that gambling may be costing more than money, and that a change could help. The earlier you notice them, the more options you have — and support is available, whatever stage you are at.
