Massive Study Links ADHD to Higher Risk of Digestive Disorders
What Happened
A review of 23 studies involving more than 1.9 million people found that those with ADHD were nearly 50% more likely to experience gastrointestinal problems than people without the condition. Researchers reported almost double the odds of constipation, a 58% higher risk of irritable bowel syndrome (IBS), and more than four times the odds of encopresis (loss of bowel control) among people with ADHD. The study was published in the Journal of Attention Disorders. ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental disorder that affects how a person pays attention, controls impulses, and regulates activity levels. It usually begins in childhood and can continue into adulthood.
Key Takeaways
Researchers say the findings strengthen evidence for a gut-brain connection in ADHD, but they stress the study shows an association, not proof that ADHD causes digestive problems. Possible explanations include ADHD-related eating habits, medication side effects, and differences in gut bacteria. Experts suggest doctors treating ADHD should also pay attention to digestive symptoms.
