I would advise not worrying too much about any specific potential problems until they actually happen, but I would suggest being keenly aware of your electrolyte intake as well as hydration as mentioned above. The J pouch is taking over for your colon which regulates electrolytes in your body, and for me that was not a smooth transition. I was hospitalized with a sodium overdose. My sodium and potassium levels vacillated wildly in the month or two after takedown. The J Pouch never completely takes over what your colon did in regulating electrolytes in your body.
