I was diagnosed back in Sept 2022. Went thru it all - 12 chemo, 28 radiation and I had an 11 1/2 hour whipple surgery. Mine was a very complicated surgery due to how the tumor was wrapped around a major artery and they had to scrape most of the nerve endings which created nothing but diarrhea. It has taking much longer to recover and I am taking shots for the diarrhea. However, I lost 52 Lbs and got down to 94lbs. I was also all bones. I tried everything but most would go right thru me. Finally, they put me on TPN which is an intravenous feeding solution. Lots of opinions on TPN and wanted it to be a last option but it has worked great so far. I have added 19 lbs so far with no infections or side effects. Perhaps, you can look into that. Praying for you both.
