Expatriate health insurance customers who have recently found themselves out of a job might want to discuss their mental health with a doctor they can trust.
According to Andy Bell, deputy chief executive of the Centre for Mental Health, there is a particular need for people to be aware of this issue in the wake of the economic recession.
"It has many causes and it is very common at any time, whatever the economic situation," he explained.
"One of the well known risk factors for depression is unemployment. That is an issue at the moment, with the numbers of people out of work increasing."
Mr Bell added that depression is "incredibly common" and takes its toll on around one in six people.
Certain people appear to be predisposed to it, but it is often the result of adverse life events, the mental health expert remarked.
