i've read a few articles that state that the human digestive system over time creates new cells that are able to absorb calories and nutrients. In essence, the malabsorption benefit of gastric bypass decreases over time such that only the benefit of restriction is left. Does anyone have insights into this? For those who are veterans of gastric bypass, do you find that the benefit of malabsorption decreases over time? I am post-op one year and 2 months. I'm very pleased with the weight loss but definitely do not lose any more weight. I am maintaining and am happy with it. But I am able to eat more than in the past. I miss the "early" days after surgery.

That sounds like an interesting article.

I'm no expert at all, but I thought that (or hoped that) the malabsorption was our saving grace.

But it would make sense what the article stated...the body will always find a way I suppose.

I'm no expert but I would think the fact that Gastric Bypass patients have to take Vitamins for life due to malabsorption that information is not totally accurate. Stretching the stomach may be a bigger issue. I look at various websites such as medscape but here's a link to Hopkins. Good luck.

I was reading about that and I swear I read that around 3 years your body starts to reabsorb things.

I don't have a link readily available, but I read that the cilia in the small intestines do adapt and regrow after a certain amount of time ( I think it said about a year out) . So the intestines it said was then able to absorb fats and calories but still not handle absorbing all the nutrients you need from food which is why you still needed to take your Vitamins.

If I can find the link I will post it here.

I found a handout that said that maladsoprtion decreases over time: http://www.muschealth.com/weightlosssurgery/nutrition/Handouts/HandoutGBP%20how%20it%20works.pdf

But no research

For the operations that have a malabsorptive component (Roux-en-y gastric bypass and Duodenal switch), the gastrointestinal tract may adapt over time to its new anatomic change. This adaptation may allow for better absorption of the consumed food, especially fats reducing the benefit of the surgery. Unfortunately, nothing short of further surgery can avert this adaptation effect. However, once again adhering to eating small meals high in Protein may limit this effect.
