This sounds like one of several possibilities. Given the onset following pregnancy (assuming vaginal delivery), you could be experiencing an overactive bladder. This is the result of an overactive detrussor muscle that controls bladder emptying. A simple treatment to test this would be to try Oxybutynin 5 mg twice a day. from your primary physician This medication stops the activity of this muscle and allows for increased filling before voiding. Less likely you could have experienced pelvic floor relaxation as a result of age and pregnancy. This is commonly associated with incontinence that occurs when laughing, crying or any activity that increases intra-abdominal pressure. A pelvic sling procedure through a Urologist would be the treatment of choice. I didn t read you mention this so I wouldn t suspect this to be a problem. Another possibility, less likely again, is Diabetes Mellitus. Having a high blood sugar can promote diuresis. You would need to get your blood sugar and Hemoglobin A1c checked. Continue to avoid drinks like caffeine, tea, sodas, cranberry juice as these may promote diuresis. Let me know if I may be of any further assistance. Marco Zahedi, MD Family Medicine
