A new study published in the Journal of Attention Disorders has suggested that those numbers may be even higher for those with attention deficit/hyperactivity disorder (ADHD).

In fact, the systematic review and meta-analysis found greater associations between ADHD and a range of gut issues, including irritable bowel syndrome (IBS) and diarrhoea.

  • Overall, ADHD was linked to a near 50% increase in the likelihood of any gastrointestinal symptoms.
  • One of the study's lead authors, Sarah Blake, who's a medical student at Warwick Medical School, said: "Almost every gut symptom we looked at: constipation, IBS, even indigestion, appeared to be associated...
