I am 84, diagnosed Sept. 2021, Type 1/II. Had 3 months chemo then Whipple March 23. No more chemo(too old), just CT scans. Feeling pretty good, working on increasing stamina. Spent 1 week in hospital after surgery, no complications. Advice: make sure you get enough calories after surgery! You may not want to eat, but you can drink. Use Premier Protein drink for protein, Ensure or Boost for carbohydrates (I used all 3). Each is about 200 calories, I needed a minimum of 1200 calories so this meant at least 6 drinks per day. Initially I was using only 3 per day(thinking 1 per meal) - but I was really starving myself - and feeling terrible. My PT alerted me, I increased the drinks to 6 per day. It took 5 days but suddenly I felt better! Had stomach cramps and my GI told me to increase Creon to 2 per meal. Again took 5 days to feel good! Good luck to you!
