I know this is an old post, but if you are still suffering, may I suggest you look into Axonics for sacral nerve stimulation. It has been shown to help with both bladder and bowel incontinence. I only have bowel incontinence probably from nerve damage from the birth of my only child which was 36 years ago, but my problem has been getting steadily as I have aged. I'm 70 years old now and have been struggling with bowel incontinence for many years. My daughter weighed in at 8 lbs. 7-1/2 ozs. and they had to use forceps to get her out plus I have a very small frame. My urogynocologist performs this procedure. I'm not sure what other specialties do it. It does require a trial phase where leads are place in the sacral nerve and all the wires and battery are taped to your backside. If you pass the 1-week trail with a 50% or better improvement in urgency and number of bowel movements, you go on to phase 2 which is surgical implantation of the device/wires. I tried everything from keeping a food diary, to low FODMAPs, to increasing my fiber, to Pelvic Floor Rehab, to daily Imodium (which helps, but causes a rebound effect for me). I am only 2 weeks post op from having the implant and have seen a dramatic change in urgency and number of bowel movements. I wish you the best of luck.
