There were no differences in the ability to sense bodily changes (e.g., heart rate, gut movements) between people with and without gambling disorder. People with gambling disorder showed lower changes in heart rate during their breathing cycles than people without gambling problems. However, this difference was mostly explained by age and more severe smoking behaviour in people with gambling disorder.
