Calls to a gambling addiction helpline have increased by more than 30% in just five years, figures show.
The National Gambling Helpline receives nearly 30,000 calls a year, with half of those contacting it concerned about their mental health.
Two-thirds of people using the service said gambling was also causing them financial problems, according to data published by the Daily Mail.
It is estimated there are 430,000 gambling addicts in the UK and that two million are at risk of developing an addiction.
Between 250 and 650 young gamblers commit suicide every year.
Tim Miller, executive director of the Gambling Commission, said it is important people struggling with gambling are able to access support when they need it.
“But a focus on preventing harm in the first place is equally important,” he added. “That’s why we will continue to take actions to require gambling companies to spot those being harmed by gambling and step in to protect them.”
