Question:
What percentage of malabsorptooin does the RNY have?

I was just wondering, the malabsorption that takes place in the RNY'er's what is the percentage of food that doesn't get absorbed? And does it last for the rest of your life?    — okbuffy (posted on July 22, 2009)

I've been trying to get an answer to this one a long time myself with no luck. I'm going to ask my bariatrician next visit, for now if you find out let me know!!

HI I dont know what % isnt absorbed but from what I understand it only last about a year and then u begin absorbing 100% of your calories...that is why the 1st yr is so crucial in weight lose

There is not a standard anwser since everyone has a differant interaction with the surgery. Some people can do fats, some can do sugar, others can't. Some absorb more than others. It is very individual. This is why you do not geta fixed response to the question.

Hi Buffy, The answer depends on how much of your intestine is bypassed during surgery. The more that is bypassed, the less you absorb. Also, not all foods are absorbed the same way. Liquids are absorbed faster than solids. Sugars are faster than protien etc.. Yes, it does last the rest of your life. That is why vitamins and protein supplements are required. I do know too, that it depends on what type of surgery you have. If your pouch expands over time you will eat more, so you will absorb more.

I was told it is about 10%, but like others have stated, it varies with everyone. This is just an average. Paula B.
