Health Issues Caused by Avoidant Restrictive Food Intake Disorder (ARFID)
Aside from stunted physical growth, individuals with Avoidant Restrictive Food Intake Disorder (ARFID) may encounter various physical and mental health complications. Those with ARFID are susceptible to conditions such as amenorrhea, electrolyte imbalances, and a low heart rate. A case study revealed that a teenage boy diagnosed with ARFID not only suffered from deficiencies in vitamins A, B12, D, E, K, and folate but also experienced malnutrition-related spinal cord degeneration. Additionally, a study involving children with ARFID found that half of the participants also had a comorbid diagnosis of generalized anxiety disorder.
Causes of Avoidant Restrictive Food Intake Disorder (ARFID)
Avoidant restrictive food intake disorder (ARFID) is a complex condition with no definitive known cause. However, scientists have identified several factors that may contribute to the development of ARFID.
Gastrointestinal Problems: Research suggests that individuals with a history of gastrointestinal issues such as acid reflux or frequent vomiting may be more prone to developing ARFID.
Mental Health Conditions: Certain mental health conditions like obsessive-compulsive disorder (OCD), anxiety, and autism have been found to be associated with ARFID. It is important to note that having these conditions does not guarantee the development of ARFID, but they may increase the likelihood.
Family History: Children with ARFID are more likely to have mothers who have struggled with eating disorders or parents with anxiety. This indicates that there may be a genetic or environmental component to the development of ARFID.
Brain Activation: Studies have shown that individuals with ARFID exhibit changes in brain activation. Specifically, there is increased activity in the areas of the brain responsible for attention, emotional regulation, reward processing, and interpreting bodily signals. These findings suggest that neurobiological factors play a role in the development of ARFID.
While these factors may contribute to the development of ARFID, it is essential to recognize that each individual’s experience with the disorder is unique, and further research is needed to fully understand its causes.
