Objective: The genetic and family studies of eating disorders (ED) and obsessive compulsive disorder (OCD) were defined that there may be a relationship and a common biological predisposition between these two diseases. Similarities in symptomatology and extreme struggles with weight and eating that can be obsessional were shown in many studies. OCD patients also exhibit a high rate of disordered eating attitudes as reported. Obsessions are the most common symptom cluster after depressive symptoms in anorexia nervosa) patients. Obsessive symptoms were shown to continue before and after anorexia nervosa. Psychology and physiology of hunger is considered to increase the obsessive structure. Aim of this study is to compare the obsessive thoughts of anorexia nervosa patients with low BMI (body mass index) at admission to hospital with obsessive thoughts of the same anorexia nervosa patients after weight gain.
Method: Twelve patients were evaluated. Eleven of them were female, one of them was male and the mean age was 24.58. At the beginning and at the end of the treatment BMI was measured and Maudsley Obsessive Compulsive Inventory (MOCI) was applied.
Results: Average BMI at baseline (body mass index): 14.86 (SD=2.12) and average BMI at the end: 18.35 (SD=1.5). Averages of obsessive thoughts of patients were compared. While MOCI checking, cleaning, doubt and rumination subscale scores at the initiation of treatment and at the end of treatment had no significant difference in test scores, MOCI slowness subscale was statistically significantly higher at low BMI than the scores recorded after weight gain.
Conclusion: It was claimed that the obsessive symptoms of anorexia nervosa şuctuated with BMI changes. In our study, it was found that only MOCI slowness subscale score significantly changed while BMI was increasing.
