There are a number of reasons why someone may develop ARFID, including medical issues (such as food allergies or gastrointestinal problems), psychological factors (like anxiety or sensory-processing difficulties), and some environmental factors (like a history of trauma, neglect or being exposed to aversive food experiences). Effective ARFID treatment will help you to identify these causes so that you can develop new ways of managing the issues and establish healthier eating patterns.
