Post Op Sleeve Stage One Two Three Diet

Yesterday was my birthday.  I’m now 56 years old and I went to Denny’s for my free Grand Slam Breakfast! Yea, as if.  My daughter ate the Grand Slam, I had one scrambled egg white, which was delicious.  However, when I announced this in my private weight loss surgery support group on Facebook, I was questioned about what stage I am in my “diet”.

Of course I had read my paperwork and I know what stage I’m on. But I wanted to reassure everyone that I knew what I was doing and quote the paper.  I won’t repeat what I wrote in the group post, because I want google to like me, but the point is I’m confused.  I know two weeks is 14 days, so what are days 15-20 considered?


This is the anticipated diet progression after your bariatric surgery. Keep in mind that tolerance/intakes will vary on an individual basis depending on the healing process. It is important not to progress too soon from stage to to stage to allow for proper digestion and absorption of diet consistencies. Adherence to this new eating plan is necessary to ensure one’s nutrition status and weight loss progression are optimized.

Day 2- Post Op: after upper GI series (x-ray test) & clearance by surgeon to initiate oral diet, stage 1: Bariatric Sugar-Free Liquid diet will be ordered.
