Good luck with your surgery. It looks like they have a good plan for you. Keep me posted.

Post my surg, I was in hospital for five days. I was on liquid diet for 2 days- then moved to a bland diet ….. jello, mashed potatoes, eggs. Gloucose testing a few times a day. After five days in hospital, my gloucose was steady & my digestion was working well. I was released with no dietary restrictions. (I have no idea if that is usual or not). Their advice was eat green vegetables and lean protein; which I began on day six after surgery.
I was told that there was a chance that I could become type 1 diabetic and that I might need enzymes. Neither of those complications have happened to me in 4.5 years.
I am careful with sugar, but I haven’t eliminated deserts completely. I never drink alcohol.
My exercise routine is not consistent- other than walking my dog a couple miles a day.

It’s not what you asked but on another note- I did not take enough time after surgery to recuperate. I had care for 3 weeks then I was back to work and on my own. I was performing physically strenuous tasks way too soon after surg, and I developed multiple ventral hernias. I didn’t want mesh implanted, so I’ve just left the hernias alone.
