Strange,
You may also want to consult with a registered dietician to see whether your diet may be a bit lacking in potassium-rich foods. After my takedown I was strongly encouraged to eat potassium rich foods, and my surgeon gave me a model diet to eat after takedown. Back in those days I was eating a lot of Gerber baby bananas which are actually pretty good! While the J Pouch makes all of susceptible to electrolyte imbalances, we can sometimes correct the situation with normal dietary changes, without taking large amount of supplements.
