Schools are struggling to deal with the rising number of pupils self-harming, according to two major teaching unions.
NHS figures obtained by BBC Newsbeat reveal a 20 per cent rise in the number of ten to 19-years-olds admitted to hospital because of self-harm injuries across England, Wales and Northern Ireland.
Hospital admissions increased from 22,978 in 2012-13 to 28,730 in the following year, the data shows.
The government says it has sought advice from experts on how to tackle self-harming and related issues in schools.
However, teaching unions the National Association of Head Teachers and the Association of Teachers and Lecturers, claim there is not as much expert medical help available as in the past due to spending cuts to local services.
Care minister Norman Lamb said: "Self-harm is a sign of serious emotional distress and it is crucial that young people get the help they need."
Mr Lamb added that a team of specialists is currently examining how to improve care in schools, and £150 million is being invested over the next five years to deal with self-harm and related issues.
