I know this will sound like a silly question to some but here goes. I've read for months now here and in other forums how after bariatric surgery total regain is possible.  I understand how it can happen but my question is, how is it mechanically possible?  If the majority of our stomachs have been bypassed ( but is still in us) than when there is regain let's say all of 100 lbs or more, where is there room for two stomachs?  And does the pouch become another entire stomach?  Again, sorry for this question but it's something I've always wondered about.

Well, when you regain weight, the weight does not stay in your stomach.  I mean, if you regain 100 pounds, the weight is distributed throughout your body.  Food passes through your stomach.  It ends up in your hips, your thighs, your arms, your belly, your face, your feet, etc.  Does that make sense?

it does, but can the pouch become as large as our stomach?

Ooops, sorry, I should have scrolled down to see that NYMom answered this question for me.

"Food passes through your stomach.  It ends up in your hips, your thighs, your arms, your belly, your face, your feet, etc."

No it doesnt.  The food doesnt end up on her arms, belly, face and feet. Well. Maybe if she eats like a toddler.

Just out of curiosity where do you think the weight will end up if you re-gain? Personally I am finding on my stomach and hips but it will distribute everywhere. The weight you lost where did it come off from?

I was asking this in regards to our stomachs/ pouches.  If  they in fact enlarge enough to be considered a second stomach.  I certainly know where those calories end up on me...I have what I like to call my child bearing hips....unfortunately 

Hi Lily2. My comment wasn't for you but Skinny scientist. Her reply made no sense. Itoo have the hips from having kids andalso the grey hair LOL

I was laughing at the funny picture that "FOOD" ending up on your hips, face and etc painted in my head.  The initial poster meant weight but wrote food.  So I was envisaging an adult wandering around with food all over their faces. You know, how kids eat. It ends up on their faces, hair, hands, etc.

Interestingly, I l have lost weight in all the places. Unfortunately, the "food" didnt stay in my boobs. Theya re little A cups!

I understand your question. You are talking about your blind stomach and your pouch. There is no food in the blind pouch so it takes very little room. The pouch can enlarge but never to the size of your original stomach. The absorption of calories is where you gain weight. Not the actual girth of the stomach.
