I'm 17 years out...About 6 months after my surgery in 2004, I developed consistent, debilitating migraines. I also started developing attitude issues, and was diagnosed bipolar. The theory was that my body chemistry changed after the surgery, causing these issues. I've had weight gain due to bad nutritional info, and have also developed Asthma. I'm not sure what exactly you're looking for... There were other medical issues, I had cancer, but I don't think that was related...
