Just wondered everyone get the same size tummy after surgery? Do they decide per person or do they have a tool that is a guide for the doctors to use on anyone?

They have a tool...down the throat..a 34 or 36 gauge...you can see how its done on Youtube

Different doctors use a different size tube, I think. A bougie is a thin tube that is sized in a measurement known as French. Mine is a 32 and here in the Dallas area, that is the size normally used. Some use a 34, but I don't know anyone whose had surgery in the past three years that has one any larger.

Each sleeve size not only depends on the bougie size the doctor uses but also how tight the doctor makes the staple line to the bougie. Some create a sleeve tight to the size of the bougie and others loosely. It all depends on the doctor and the patient.

I asked my surgeon what size bougie size he uses. He says a snug 40. I trust him, so I'm hoping all goes well.

Everyone has a different size stomach yes they use different tools but our genetics have some impact on the actual size of our stomachs.
