Idiopathic constipation in childhood is a problem that can cause a myriad of difficulties to both the child or young person and their family. There are a number of precipitating factors that may result in painful or infrequent bowel movements and/or soiling. Empowering children and young people together with their parents and carers forms one part of the treatment plan, but it is the adequate and effective use of laxative therapy alongside diet and lifestyle modifications and appropriate advice and support that can best help children to overcome this poorly understood condition. Professionals need to demystify how the bowel works and help children and young people to overcome their embarrassment in seeking help for this common childhood condition. The new NICE guideline will help all practitioners in recognising their role in helping children, young people and their families.
