Chew and Spit (CHSP) in bariatric patients: A case series

Given that no specific intervention has been developed to target the pathological eating behavior «chew and spit», it is paramount that we understand the prevalence of this behavior is, and how it may affect weight loss and weight loss maintenance. One group of particular interest is bariatric surgery patients. The aim of this descriptive study was to gain preliminary insight into «chew and spit» in a bariatric sample.

The identification of pathological eating before and after bariatric surgery is important to detect behaviors that might hinder optimal weight loss post-surgery. Chew and spit (CHSP) is a behaviour characterised by masticating food and expelling the contents of the mouth before swallowing. CHSP is most often used as a weight control measure and allows the individual to taste the food without ingesting it fully. Studies of CHSP have alluded to several cohorts more likely to engage in the behaviour, one such group being bariatric surgery patients. This study examines three individuals who have undergone bariatric surgery, and who reported engaging in CHSP behaviour either before or after their procedure. Pre-surgery, two participants reported that they engaged in CHSP, compared to one patient post-surgery. The current study provides a starting point for the exploration of CHSP as a symptom of pathological eating in bariatric patients, highlighting the need to further explore CHSP before and after weight-loss surgery.
