Question:
Does anyone know what percentage of calories we actually absorb?

I know this will vary from person to person, but I'm wondering if anyone has heard any figure regarding what percentage of calories we actually absorb?    — tlg6056 (posted on April 24, 2001)

I am a prox RNY. My surgeon said that there is basically no calorie malabsorption, in effect I will absorb all calories. There is some vitamin and mineral malabsorption though. He was referencing the surgery his does, as Barb said maybe that is different with a longer bypass. I believe there is calorie malabsorption with the BPD/DS, I've seen figures but don't remember off the top if my head.
