Understanding the impact of obesity on pelvic organ prolapse is important. Objective: To evaluate the association between obesity and uterine prolapse in 108 women with uterine prolapse. The degree of prolapse was determined by the POP-Q system. The PFDI-20 questionnaire, POPDI-6, CRADI-8, UDI-6 subscales were used. Calculated body mass index BMI. The average age of patients was 44.11±4.38 years. Stage I prolapse was noted in 28.7%, stage II -in 49.1%, stage III -in 18.5%, stage IV -in 3.7% of patients. The total score on the questionnaire was 95.58±25.0. POPDI-6 -46.31±11.32, CRAD-8 -19.17±6.17 and UDI-6 -32.59±10.27 points. The average BMI was 24.88±3.22 kg/m2.Taking into account the value of BMI, the patients were divided into 2 groups: group I -53 (49.1%) patients with BMI 29.9 -33.6 kg / m2, group II -55 (50.9%) patients with BMI 19.3-29.8 kg/m2. In group I, patients aged 25-35 years were much less common (p=0.002) and patients aged 46-55 years were significantly more common (p<0.001). In group II, normal BMI occurred in 87.3% of cases (p<0.001), overweight -in 12.7% of cases (p=0.374). In obese patients, BMI correlated with uterine prolapse scores in a weak, direct, but statistically non-significant relationship. According to the results of a prospective study, it was found that in women with uterine prolapse and obesity with stages II and III of uterine prolapse, the body mass index is higher than in stage I. Obesity correlates with uterine prolapse by a weak, direct, statistically insignificant relationship.
