Let me just start by saying that you have just begun the long healing process. I am 2-l/2 years after whipple and still have issues. Not to say that things don't get better, they just are never the same as they were. In addition to all the work they did inside of you that needs to heal, I found that after the fact I had to deal with the trauma of the ordeal that I went through. Physical pain causes mental anguish and likewise, mental anguish actually can cause physical pain.
I don't think that the doctors prepare us very well for our futures after surgery. You can't mess with mother nature and not expect something to give. Regarding stools, our digestive systems are rearranged and do not function in the same manner. Sometimes food goes too quickly through our system so it does not process the fat (this causes floating stool). I personally do not take creon as I seem to do okay without, but if I understand what others have mentioned it basically helps with gas and other unpleasant side effects of not processing fats.
In addition to your surgeon, you should have a good GI doctor to help with digestive issues and a caring primary doctor that can help with other things that come up.
I think the best thing I did after surgery was to get out and walk. Start slowly and build up to a comfortable amount for you. I found it helped get my muscles back in shape. I pretty much stayed at the same weight after the initial loss for about two years, but now I'm trying to be careful because it is creeping up a little. (I definitely could afford the loss and am enjoying the "new" me).
Incisional hernias are very common after this surgery and can cause discomfort (though not always). You can usually tell if you have one by having a distended stomach as the day goes on. I noticed mine about three months after surgery and it got bigger as time went on. I eventually had it repaired about one year later.
In closing I would say, everyone is different and you've just been through one tough surgery. Be patient and give yourself a break. It is a slow healing process and you should not expect to be back to normal in this short amount of time.
There is a great thread on here called my whipple story by e2momma where she really tells her whole experience with the whipple procedure and the after effects. It was around the beginning of 2010. I have to say that it made me feel like I was not alone in this process.
Prayers for a blessed holiday season and hope this was of some help.
