Restricted intake self-harm (RISH)

Restricted intake self-harm (RISH) refers to intentionally limiting food or fluids as a form of self-harm rather than for weight or body image reasons. RISH is an emerging formulation-led construct, rather than a diagnosis, that was developed with lived-experience input. Experts by experience highlighted how existing labels like 'disordered eating' often misrepresent intent and lead to clinical misunderstandings. Individuals describe restriction to regulate emotions, express distress, seek care or commit suicide. Emerging evidence suggests this behaviour could be relatively common among young people yet is under-researched and frequently misclassified. Recognising RISH can help ensure appropriate adapted treatment approaches are created.
