Constipation is not much talked about, but it affects one in three children and will not go away by itself. ERIC, The Children’s Bowel and Bladder Charity, is the only UK-wide charity dedicated to children’s continence services. It provides online resources on all things wee and poo, webinars for healthcare professionals and parents/carers, and a free Helpline — on which the most common call is about constipation. Here, Sunni Liston, ERIC nurse, discusses constipation and how to help treat it.
