Guest guest Posted July 23, 2002 Report Share Posted July 23, 2002 What I was referring to, is that the lower portion of the stomach is where our vitamins and minerals are " normally " through digestion, extracted from what we eat. Not having the lower portion of the stomach available for this process, we must use perscriptioned iron, perscriptioned potassium, as well as accross the counter calcium supplements, vitamin E to make up for this malabsorption process. In taking such, we are supplementing the minerals and vitamins we need, that would normally have been extracted from what we eat. It can be complicated, but understand that the basis of how the gastric by-pass works is on the premise of " malabsorbtion " , if it were not for this we would not be as successful at losing weight! ///Bob iron question > It has been posted in here that iron is absorbed at the bottom of the stomach > which is why we need to supplement.

Guest guest Posted July 26, 2002 Report Share Posted July 26, 2002 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.
