Had you been with Kaiser for a while or was this your first Kaiser visit at all? I have been with Kaiser since Jan 2014 so they have a record of my weight. I've been consistently gaining 10-20 lbs yearly, regardless of how much I diet. I am thinking because they have a record of my weight, they won't just see me as a 40 bmi, and require 3 years of consistently being 40 or above.
I am in Orange County, but I think the bariatric program I'd go to is in South Bay. Classes are in Orange.
