The number of hospital admissions after people have deliberately poisoned themselves has risen by almost 50% in a decade.
NHS figures show there were more than 114,000 cases in England, Wales and Northern Ireland during 2011.
That's compared to almost 79,000 in 2001. Figures for Scotland aren't available.
