I had a Roux en Y gastric bypass 25 years ago. I lost over 100 lbs, but have gained about 50 back over the years. Neuropathy started soon after, I have been on Vitamin B12 shots monthly since then. I have similar symptoms as you at 85 years of age. ai saw a neurologist who said there is nothing new for my condition, Mine is not due to diabetes, but my A1C is around 6.2. I have struggled with weight issues my entire life. I am considering a weight loss injection of tirzepatide, but fear any new drug will exacerbate my neuropathy further.
