wow...I have never heard anyone talk about NY presb surgeons like that. I have never been to Dr. Lee, but Dr. Milsom, his partner, performed my surgery and I have seen Dr. Sonoda also. From what I have learned and researched regarding this group, you are in very good hands. I researched my surgery well over a year before selecting Dr. Milsom. I am not sure how much experience Dr. Lee has with jpouch surgery as he is fairly new to the practice but Dr. Milsom assured me they are all top notch if I ever needed to be treated by any of them and I believe he hand selected all of them.
You have only had your jpouch for a very short time. It takes a LONG time for some of us for the jpouch to adapt and often there are many hurdles along the way. Having said that,I do not think going to the bathroom as much as you are is normal at this time but I have heard of others who struggle with very high output for a bit. Patience is something you really need right now and persistence if there may be something else going on with you.
The pouchoscopy will tell them whether you are having any inflammation issues like pouchitis which could cause increased frequency. Are you still on prednisone and weaning off it? I know I had some issues when I was going through that period. Hopefully you are keeping up with your fluids if you are going that often and try to eat more bulking foods if possible like rice, pancakes, breads etc to see if that slows you down a little bit. Wishing you good luck. I am sorry you are experiencing this and know how terribly frustrating the adaptation period can be if that is what is going on with you.
