Re: iron question

[Guest guest]

The stomach is where food is digested. No nutrients are absorbed in the

stomach. The small intestine consists of three parts, the duodenum, the

jejunum and the ileum. The body absorbs most of its iron and calcium

through specialized receptors in the duodenum. The RNY bypasses the

entire duodenum and part of the upper jejunum. The iron and calcium

that is absorbed is done so by receptors in the remaining part of the

jejunum and ileum which are less efficient at absorbing them. Also, the

food passing through has not been subjected to breakdown through prior

digestion. The lack of full digestion and bypassing of the jejunum

makes it for iron absorption to occur. That is the primary reason why

supplementation is needed.

Not in all people . . .only 6 inches of doudenum have been bypassed in the

case of my surgeons patients . . .
