Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Eating disorders are solely caused by psychological factors. | While psychological factors can contribute to the development of eating disorders, there is also evidence that biological and genetic factors play a role. The gut-brain dialogue, or communication between the digestive system and the brain, can also impact eating behaviors. |
| Gut-brain dialogue only affects hunger and fullness signals. | The gut-brain dialogue involves complex interactions between hormones, neurotransmitters, and other signaling molecules that can influence not only hunger and fullness but also mood, stress response, and even cognitive function. Disruptions in this communication may contribute to disordered eating patterns. |
| All individuals with disordered eating have an underlying issue with their gut-brain dialogue. | While disruptions in the gut-brain dialogue may be present in some individuals with disordered eating patterns, it is not necessarily a universal factor for all cases of eating disorders. Other contributing factors such as genetics, environment, trauma history should also be considered when evaluating someone’s risk for developing an eating disorder. |
| Addressing gut health alone will cure an individual’s disordered eating behavior. | Improving one’s gut health through diet changes or supplements may improve overall physical health but it does not address underlying psychological issues that contribute to disordered eating behaviors such as anxiety or depression which require therapy interventions. |
