Kaiser Richmond does require a 10 % weight loss and there are some classes required, but not as many as the options program in Southern California. Maybe, suggest to her, that she call the Bariatric Department with her questions. Also, the orientation will cover many questions. The process varies, according to how long it will take a person to lose the required 10 % weight. When she has a consultation with the surgeon, he/she will tell her how much weight she needs to lose prior to surgery. If she loses the required amount of weight quickly, then she will receive the surgery sooner, rather than later.
I didn't go through Richmond, but all of the Northern CA Kaisers require the 10% weight loss.
All referrals to the Bariatric Department, must come from a referring PCP.
