Gambling harm
Also called Gambling addiction, Problem gambling
An addiction with no substance and no smell, which is why it is usually discovered through money rather than behaviour. Treatment is free on the NHS.

What it is
Gambling that causes harm to the person or to those around them. It is recognised as a behavioural addiction, and it affects the same reward pathways as drugs and alcohol.
It hides better than any other addiction. There is nothing to smell, nothing to find, and the person can be losing thousands from a phone while sitting in the room. Families typically discover it through money: an unexplained loan, an emptied account, a bailiff letter.
It rarely travels alone. Depression, anxiety, alcohol and substance dependence are all more common in people who gamble harmfully, and the suicide risk is substantially raised. That last point is why this entry does not treat it as a money problem.
Two medical causes deserve naming. Dopamine agonist medicines used in Parkinson's disease and restless legs syndrome can cause sudden compulsive gambling, shopping or sexual behaviour in someone who has never done it before. It is a side effect, it is reversible when the dose is changed, and both the person and the family are often devastated by behaviour that was pharmacological.
NHS gambling clinics now exist across England and take self-referrals. Very few people know that.
Signs you might notice
Money that does not add up: borrowing, unexplained shortfalls, selling possessions, bills unpaid while income seems fine.
Secrecy about the phone, being awake and online at night, and defensiveness about money.
Chasing losses, betting more to recover, and being unable to stop while ahead or behind.
Irritability or restlessness when unable to gamble.
Lying about the extent, and gambling more when stressed or low.
Neglecting work, family or health.
In someone on a dopamine agonist, any of the above appearing for the first time is a medication question, urgently.
Urgent: talk of suicide, hopelessness about debt, or giving possessions away. Debt-related suicide is a real and specific risk. See suicidal thoughts.
How it can affect day-to-day life
The shame is severe and it is what delays help. People describe the debt as the thing they cannot say out loud, more than the gambling.
Families are harmed directly: partners and children experience the financial loss, the secrecy and often the aftermath of a relapse, and support exists for them in their own right rather than as an adjunct.
Practical blocking works better than resolve. Bank gambling blocks, GamStop self-exclusion across online operators, blocking software, and removing card details all reduce access at the moment it matters.
Paying off somebody's debt without treatment reliably makes things worse. Debt advice is a separate and necessary strand.
Relapse is common and is not a reason to stop treating. The pattern is the same as any other addiction.
Supporting someone well
Ask about it directly. Nobody volunteers this, and two straightforward questions about whether gambling has caused problems are enough to open it.
Refer to the NHS gambling service. In England these accept self-referral and are free.
Set up the blocks: GamStop, bank gambling blocks, blocking software, and removing saved payment details.
Separate the money from the addiction. Get free debt advice, and do not simply clear the debt.
Get support for the family in their own right.
For anybody on a dopamine agonist, contact the prescribing team urgently rather than waiting for the next appointment. Do not stop the medicine abruptly.
Take suicide risk seriously and ask about it plainly.
