Key facts

Compulsive gambling at a glance.

The essentials in plain English - what it is, how common it is in the UK, and why it matters clinically.

  • What it is

    Gambling disorder is persistent, recurrent problematic gambling that causes significant clinical impairment or distress. It is the only behavioural addiction recognised in DSM-5-TR and ICD-11.

  • How common

    Around 250,000 people in the UK meet criteria for problem gambling, with a further 300,000 at moderate risk (Gambling Commission).

  • Why it develops

    A mix of genetic vulnerability (up to 60 per cent heritability), reward-pathway and dopamine biology, impulsivity and easy digital access.

  • Comorbidity

    Depression, anxiety, substance misuse, ADHD, bipolar, personality disorders and PTSD are all common alongside it.

  • Suicide risk

    People with gambling disorder face a suicide risk around 15 times higher than the general population - it is a core clinical priority.

  • It is treatable

    CBT, motivational interviewing, naltrexone off-label, GAMSTOP self-exclusion and peer support all have evidence behind them.

Why this guide matters

A clinical illness, not a moral failure.

Gambling harms are common, treatable and often hidden. The three points below set the frame for the rest of the page.

  • Ask, and it can be found

    The two Lie/Bet questions and the PGSI take under a minute and reliably surface a hidden problem in primary care and mental health settings.

  • Treat the brain and the environment

    CBT, naltrexone and treating comorbid mental illness sit alongside GAMSTOP, financial safeguards and peer support - both layers matter.

  • Never miss suicide risk

    The suicide risk is around 15 times higher than the general population. Every review needs an honest question and a safety plan.

How the diagnosis is made

From first honest question to a specialist plan.

The steps a UK GP, psychiatrist or specialist gambling service will normally follow, in order.

  1. 01

    Assessing

    Normalised screening

    The Lie/Bet questions - ever felt you needed to bet more, ever lied about your gambling - and the PGSI can be woven into primary care and mental health reviews.

  2. 02

    Assessing

    Detailed gambling history

    Types (online, sports, casino, FOBTs, skin gambling, crypto), duration, amounts staked, debt, triggers, chasing losses and impact on work and family.

  3. 03

    Assessing

    Mental health assessment

    Depression, anxiety, substance misuse, ADHD, bipolar, trauma and - always - suicidality with a clear safety plan.

  4. 04

    Confirming

    Medication review

    Dopamine agonists (ropinirole, pramipexole) used for Parkinson's or restless legs can precipitate gambling. Review and, in discussion with a neurologist, stop.

  5. 05

    Confirming

    Financial and safeguarding review

    Debt, bankruptcy risk, dependants, safeguarding of children and vulnerable adults, and any criminal-justice concerns.

  6. 06

    Preparing

    Family and social assessment

    The impact on partner, children and carers - and their own support needs through GamAnon and carer services.

  7. 07

    Preparing

    Specialist gambling referral

    NHS National Problem Gambling Clinic and regional NHS services, GamCare and, where indicated, residential care with Gordon Moody.

Typical timeline: from first honest conversation to a specialist plan in weeks.

Symptoms

The DSM-5-TR criteria in plain English.

A diagnosis needs 4 or more of the following within 12 months, causing significant distress or impairment. The last card is the safety trigger.

  • Tolerance

    Needing to gamble with larger amounts of money to achieve the same excitement.

  • Withdrawal-like restlessness

    Feeling restless or irritable when trying to cut down or stop.

  • Loss of control

    Repeated unsuccessful efforts to control, cut back or stop gambling.

  • Preoccupation

    Persistent thoughts about past sessions, planning the next one or ways to get money to gamble.

  • Gambling to escape

    Gambling when feeling distressed - anxious, low, guilty or helpless.

  • Chasing losses

    Returning after losing money in order to get even - the classic hallmark of the disorder.

  • Lying and concealment

    Lying to family, friends or clinicians to hide the extent of gambling.

  • Red flag - suicidality or bailouts

    Jeopardised job or relationship, reliance on others for money, or any suicidal thoughts - urgent priority.

Treatment

How gambling disorder is treated in the UK.

CBT and motivational interviewing lead. Naltrexone reduces cravings. GAMSTOP, financial safeguards and peer support build the environment for recovery.

  • Cognitive-behavioural therapy

    First-line and evidence-based - cognitive restructuring of gambling beliefs, trigger management, behavioural change and relapse prevention.

  • Motivational interviewing

    A collaborative style that strengthens the person's own reasons for change - often used at the start of treatment.

  • Naltrexone

    Opioid antagonist used off-label at 50 to 100 mg to reduce urges and cravings. Nalmefene has a similar profile.

  • SSRIs and mood stabilisers

    For comorbid depression, anxiety and bipolar-spectrum illness - not a stand-alone treatment for gambling itself.

  • GAMSTOP self-exclusion

    Free national register that blocks access to all UK-licensed operators for 6 months up to 5 years. Combine with Gamban or Gamblock software.

  • Financial safeguards

    Debt advice via Citizens Advice, StepChange or National Debtline, budgeting, third-party account controls and, sometimes, power of attorney.

  • Peer support and 12-step

    Gamblers Anonymous, GamCare peer groups and, for families, GamAnon - alongside residential options at Gordon Moody where needed.

  • NHS specialist gambling clinic

    The National Problem Gambling Clinic and expanding NHS regional clinics for adults and young people. Young people also have Big Deal.

Red flags

When compulsive gambling needs urgent attention.

Some situations cannot wait for the next appointment. These are the ones that need action today.

  • Suicidal thoughts or plans

    Suicide risk is around 15 times higher than the general population. Any suicidal ideation needs same-day mental health assessment and a written safety plan. Samaritans 116 123 is available 24/7.

  • Immediate financial crisis

    Imminent bankruptcy, eviction, loss of livelihood or inability to feed a family - refer urgently for debt advice and safeguarding review.

  • Safeguarding of children or adults

    Where dependants are at risk of harm, neglect or destitution - follow local safeguarding pathways alongside clinical care.

  • Dopamine agonist-precipitated gambling

    New gambling behaviour in someone on ropinirole or pramipexole is a medication side effect - stop or switch in discussion with the neurologist.

  • Criminal-justice involvement

    Theft, fraud or offending to fund gambling needs joint clinical, legal and social care input rather than punishment alone.

  • Severe comorbid mental illness

    Untreated bipolar, psychosis, severe depression or PTSD alongside gambling needs psychiatric assessment before or alongside gambling treatment.

  • Alcohol or drug dependence

    Coexisting substance misuse worsens outcomes and suicide risk - treat in parallel with addiction services.

  • Domestic abuse or coercion

    Financial abuse and coercion often sit alongside gambling harms - screen carefully and refer to specialist support.

  • Young people and gaming crossover

    Loot boxes, skin gambling and in-game purchases can lead into gambling harms - refer to Big Deal, YoungMinds and school-based support.

Frequently asked

Everything we get asked about compulsive gambling.

Quick answers on diagnosis, medication, treatment, suicide risk and self-exclusion.

  • What is compulsive gambling?

    Compulsive gambling, or gambling disorder, is persistent and recurrent problematic gambling that causes significant impairment or distress. Under DSM-5-TR it needs 4 or more criteria within 12 months, including chasing losses, tolerance, preoccupation, lying about gambling and reliance on others for money. It is the only behavioural addiction recognised in DSM-5.

  • How common is problem gambling in the UK?

    The UK Gambling Commission estimates that around 250,000 adults meet criteria for problem gambling, with a further 300,000 at moderate risk of harm. Rates are higher in men, in people with mental health conditions and in some occupational groups.

  • Can medication cause gambling?

    Yes. Dopamine agonists such as ropinirole and pramipexole, used in Parkinson's disease and restless legs syndrome, can precipitate gambling and other impulse control disorders. If gambling appears after starting one of these drugs, review the medication urgently with the prescribing neurologist.

  • What treatment works for gambling disorder?

    Cognitive-behavioural therapy is first-line and best evidenced, often alongside motivational interviewing and peer support. Naltrexone 50 to 100 mg can reduce cravings off-label. GAMSTOP self-exclusion, financial safeguards and family support are essential practical layers. Comorbid depression, anxiety or substance use are treated in parallel.

  • Is gambling disorder linked to suicide?

    Yes, strongly. People with gambling disorder have a suicide risk around 15 times higher than the general population. Any suicidal thought needs urgent mental health assessment and a written safety plan. Samaritans on 116 123 and NHS 111 option 2 are available 24/7.

  • What is GAMSTOP and how do I sign up?

    GAMSTOP is the free national self-exclusion register for Great Britain. Once you register, all UK-licensed online gambling operators are required to block your account for a chosen period of 6 months, 1 year or 5 years. Registration takes a few minutes at gamstop.co.uk and is a strong first step, best combined with Gamban or Gamblock device-level blocks.
