How is MGB different to RNY help



Recommended Posts

Hey guys hope all is well.

I've been reading but unable to find the exact answers.

It looks as though there's no major difference?

Can people with MGB tell me does it still cause malabsorption and the need for all the Vitamins? Is the malabsorption as much as normal RNY?

I'm just trying to get my head around why the 2 exist if they offer same results

Thanks

Hi Mikeyy,

The MGB and the RNY are different in that the MGB only has one joining, or anastomosis, not two joinings (anastomoses) as with the RNY. Because both are bypassing feet of the small intestine, they are both malabsorption surgeries. And the malabsorption is the same for both.

Here is a demonstration of the MGB:

Hope this helps!

I understand the procedural difference just wondering is there any difference in calorie absorption or Vitamins needed?

Any difference in the size of pouch?

Any difference in weight loss?

If they do the same overall what's the reason for one or the other?

The mini GBP creates a sleeve like stomach that will use stomach acids to break down foods and Vitamins etc. so the absorption will be greater. The traditional RNY will only have a small pouch that will not use acids like the sleeve to break down what's ingested. People that choose the traditional RNY over the MGBP do so for the same reason people go with the RNY over VSG.... acid reflux or GERD. The MGBP is similar (maybe slightly better) to the sleeve in weight loss statistics according to the interwebs.

I think it makes sense I guess I really need to have a good long chat to a surgeon to decide between the 2. Tnx

Actually, it is not a sleeve. The acids do not meet the food until after the food has made it some way down the small intestine, just like the RNY. The pouch is very similar to the pouch that is with the RNY. Both pouches will only allow 2 to 4 oz of food or liquid at a time, right after surgery. It is the same malabsorption as with the RNY. The MGB is considered to be less chance of complications, less than the RNY. Weight loss is better than with a sleeve and comparable to the RNY. An experienced surgeon can do the MGB in a way that eliminates the chance for bike reflux. MGB takes care of acid reflux like the RNY. Some bariatric surgeons suggest that the MGB is better than the RNY in pretty much every way.

So people choose MGB over RNY because it is just as effective and safer. People choose MGB over sleeve because of the malabsorption and because it can get rid of acid reflux issues.

I answered the question of malabsorption and the need for Vitamins in my first post. As far as weight loss, it is comparable to the RNY. Both the MGB and the RNY cause more weight loss than the sleeve.

      I broke 150 lbs today!!!!
      150 lbs has been my wall for the past 15 years.  I've dieted down to the low 150s 3 times only to regain what I lost and more. 
      I am now officially 149.7 lbs as of this morning.  Yay me!

      Tomorrow is surgery day...  I'm not sure if I'm nervous, anxious, excited or a little bit of all three.  I honestly thought I would be freaking out at this point, but I'm much calmer than that.  I suppose the last 7 months of preparation both physically and mentally has brought me some peace.  I say this now, but when I try to sleep tonight, that may be a different story.  
      I appreciate everything I've read on this forum that has helped me to prepare as much as possible.  I know this part of my journey may not be the same as someone else's, but having a good frame of reference helps a ton. 
      The most exciting and most difficult part of the journey begins tomorrow...

      Hey ya'll. SO. I got down to 199 for the weigh in but gained it all back right after. I have to do another month of weight management. They switched out the nutritionists at the last second and she said she doesn't pass anyone unless they have 5 veggies a week. I'm starting metformin and Farxiga today. Doc found a little bit of blood in my urine but wasn't too concerned. I'm trying not to freak myself out either. Depression is a little more intense than usual. I'm all over the damn place.
