What are your concerns? – 22.5% had OAB • What is your most distressing symptom? – 48.0% of those with OAB had incontinence • How are you handling your urinary symptoms? – What do you mean you urinate frequently? • Overweight and obese women with T2DM: high prevalence of UI – How long have you experienced these symptoms? – Higher than other complications commonly associated with diabetes • What have you tried to solve your problems? (retinopathy, 7.5%; microalbuminuria, 2.2%; neuropathy, 1.5%)2 • When asking these questions: • Important implications for screening for bladder dysfunction – Respect the patient’s situation – Consider a treatment plan – Aim for patient-centered medicine T2DM, type 2 diabetes mellitus. 1.
