Questionnaires BSDS, MDQ, and demographic questionnaire were used, and those who showed signs of bipolar disorder were further evaluated through SCID-5. Regarding gender, 24.4% of the total number of obese patients studied were male and 75.6% were female. Twenty-two percent of obese patients suffered from bipolar disorder. Among people with bipolar spectrum disorders, 21.8% had bipolar disorder I, 9.1% had bipolar disorder II, 50.9% had bipolar disorder NOS, and 18.8% had cyclothymia. In the control group, 11 patients (11%) had bipolar disorder, non-obese individuals had significantly lower values compared to obese individuals (p = 0.001), 4 patients (4%) had bipolar disorder type II, and 7 (7%) had bipolar disorder NOS.
