Merycism is a medical condition characterized by the persistent and repetitive regurgitation and re-chewing of food after it has been swallowed. Also known as rumination syndrome, it primarily affects infants, young children, and individuals with intellectual or developmental disabilities.
The process of merycism involves the contraction of the muscles in the abdomen, which forces the undigested food to travel back up into the esophagus and mouth. Once in the mouth, the individual chews the food again, creating a continuous cycle of swallowing and regurgitation. This condition often occurs within the first 30 minutes after a meal, and the regurgitated food may not be digested properly.
While the exact causes of merycism are not fully understood, it is believed to be associated with emotional or psychological factors, as well as sensory and motor abnormalities in the digestive system. Stress, anxiety, and certain eating habits may contribute to the development of merycism. It is important to note that merycism should not be confused with vomiting, as it involves voluntary and deliberate regurgitation.
The symptoms of merycism include repeated regurgitation of food, re-chewing, and re-swallowing, which can lead to weight loss, malnutrition, dental problems, and digestive disturbances. Treatment for merycism often involves a multidisciplinary approach, including behavioral therapy, dietary modifications, and psychological support. In some cases, medications may be prescribed to manage the underlying causes or symptoms.
Overall, merycism is an unusual medical condition characterized by the repetitive regurgitation and re-chewing of food, which can have significant physical and psychological impacts on affected individuals.
