Thank you for your detailed response. I am glad to hear she is home, I hope she recovers fully. I asked the 3 doctors I have seen if removing the tail of the pancreas would cause loss of function (specifically diabetes) and all of them told me no. I am reading here however, it seems most people who had this surgery are now dealing with diabetes so now I am confused.
I agree on walking, I had my appendix removed years ago and I remember my recovery was awful because no one told me to walk and every time I tried I was in so much pain, I just couldn't. I have 2 weeks until surgery, I intend to intensify my exercise routine and eat a healthy diet hoping those things will help me during recovery. I exercise and eat healthy already, but now I am even more concerned because of what lies ahead. Thank you for your advice, I look forward to reading your updates and that your wife will make a full recovery.
