ARFID (Avoidant Restrictive Food Intake Disorder) is also known as “extreme picky eating” where people avoid or restrict foods for reasons other than weight loss or body image concerns. This includes: texture/sensory issues with food, fear of choking or throwing up, fear of new/unfamiliar foods, or low appetite that is not explained by a medical condition.
Rumination Syndrome, also known as Rumination Disorder, is when food is regurgitated during or after eating. The food is either rechewed, reswallowed, or spit out. Regurgitation can happen spontaneously or voluntarily (often linked to anxiety/stress).
