Objective: The objective of this study was to evaluate the impact of obesity on pelvic floor function in women.
Research methods and procedures: This was a prospective controlled study of 20 morbidly obese female patients planning to undergo gastric bypass surgery and 20 age-matched female controls. Subjects completed symptom and impact questionnaires, including the Incontinence Impact Questionnaire (IIQ-7), Urogenital Distress Inventory (UDI), the Kobashi Prolapse Symptom Inventory and Quality-of-Life Questionnaire (PSI-QOL), and Index of Female Sexual Function. Data were analyzed with Wilcoxon or ratio chi2 tests.
Results: Mean weight was 295.7 +/- 87.9 lbs in the study group and 144.79 +/- 33.07 lbs in the control group. Mean BMI was 52.65 +/-14.49 kg/m2 in the study group and 25.11 +/- 5.27 kg/m2 in the control group. According to the IIQ-7, urinary incontinence significantly affected lifestyle in the study group. The total IIQ-7 score was also significantly affected in the study group (p = 0.03). The UDI indicated more urinary leakage with activity (p = 0.04) and more incidents of small amounts of leakage (p = 0.02) in the study group. According to the PSI-QOL, women in the study group experienced constipation more often because of difficulty in emptying the rectum (p = 0.04). The PSI-QOL score was higher in the study group (6.75 +/- 6.84) than in the control group (2.65 +/- 3.03; p = 0.04). There were no significant differences between groups regarding sexual function.
Discussion: Morbid obesity is associated with a significant negative impact on urogenital health. Sexual function did not seem to be affected in women who are morbidly obese.
