Chewing and Spitting: A Little-Known Eating Disorder Symptomby Scott Crow, M.D.
What is it?
An eating disorder topic that’s been getting a lot of media attention lately is Chewing and Spitting (CHSP). It’s exactly what it sounds like— the habit of chewing food to enjoy the taste, then spitting it out to avoid unwanted calories or the guilt of eating a “bad” or feared food. CHSP can occur on its own, but is more often seen alongside other eating disorders symptoms. A cross-sectional study has shown that there is a strong association between being diagnosed with an eating disorder, like anorexia or bulimia, and lifetime CHSP behavior.1
What do we know?
Among individuals with eating disorders, CHSP behavior most often occurs in a younger subset.2
CHSP without the presence of an eating disorder often occurs in individuals with diabetes, in those who have undergone bariatric surgery, and in athletes following strict diets.3
CHSP is significantly associated with behavior used to compensate for consuming calories, meal restriction, and lower BMI.1
Effects on health and wellbeing
If left untreated, CHSP can have serious health consequences. CHSP can lead to malnourishment, swollen salivary glands, damaged teeth, stomach ulcers, and hormonal imbalances. Others effects include social isolation, financial repercussions, and psychological consequences such as anxiety, low mood, guilt and shame.
