My personal view on this is that if soda caused gas before your ostomy, it likely will cause gas after. And Sodastream carbonation, from what I understand, is no different from regular soda. 

But carbonated beverages don't cause gas for everyone, and the only way you'd know is to try :) 

I myself do not believe CO2 in drinks causes gas.  The CO2 should quickly be absorbed by the body at body temperature,   if you don't burp first. 

Ive gotten gas quickly by cheese or sour cream.  Rice at dinner tends to cause gas later.  But the idea that CO2 from drinks makes its way to your stoma basically goes against all the chemistry ive learned.

@dogtalkerer I wonder if gulping plays a bigger role. People who drink out of cans are no doubt swallowing a lot of air, too.

Interesting question... as one with an ileostomy & short short gut syndrome & yes I said short twice, gas is something I rather dreadfully fear!! Lololol!!  However I also have too much scar tissue from about 9 surgeries & know that my guts are adhered to the wall of my abdomen & other tubes of intestine of whatever I have left, (not much) ! Lol!   Not fun at all when gas makes itself known.  

I'll drink gingerale but am aware of some intestinal gas build up after so I've done my best to water the bubbles down some with fruit juice.  I avoid foods that cause me gas like you would not believe. 

As Master Eric said... basically we each process foods & *bubbly drinks*  & dairy products differently. Many of them can cause gas build up in some individuals. So maybe try it at a time where you can deal with it & find out what your personal inbuilt system can handle & then I guess you'll know. 

One thing I think we can all agree on when it comes to foods & drinks,  especially when starting out is. . .   "everything in moderation."

Thank you all for your post's.Yes we all react diferently.Lol.Could you imagine if we were all the same? Give robots a whole new meaning.

@Vegan    With regards to your comment on gulping.Would this also apply to water bottles filled with ice.I have a big one I am gulping water from all the time. It only has a 1 inch opening. So if I am gulping could I be taking in to much air? Tk's again for all your help.

everybody can experiment with this at home.   wait for a time you ususally expect the ostomy to be quiet, then drink some carboanted water, then wait.    using a carbonated beverage with other things in it would ruin the experiment, soda pop, natural sodas, beer......     or you can add carbonated water to a drink that doesn't cause you gas and  see if the carbon dioxide is causing the problem. 

most people eat/snack when drinking carbonated drinks, so you end up with a mixture. 

i have a colostomy, 1, 2 or 3 beers while preparing dinner seems not to effect me, what I eat does.

of course you also need a time limit.  if gas comes 4-6 hrs later , I might wonder

If you find that you burp a lot after drinking from that bottle filled with ice, then it could be that you're swallowing too much air.

Simply gulping the liquid shouldn't cause any excess air to be swallowed, but some people do end up swallowing air along with their drink. 

VO take a long "think about it".   its really an interesting topic.   we all swallow air when drinking,  but i think even more while eating.    think about soup, you open your mouth to fit the spoon, close your mouth and swallow the soup, but what about all the air in your mouth, goes down with the soup.   more so I think eating a sandwich.   or eating popcorn .....

so I would say eating ingests the most amount of air.  all those bites of air with each bite of dinner.  i still think the majority of the CO2 separates from the cabonated drink and you burp it out. remember how flat warm soda gets. your stomach is in the high 90's  F.

a quick but poor search stated 25% of a fart is from swallowing air, I'd say not a large amount.  plus it really requires more reading to get some better figures but who's got the time.

@dogtalkerer Since drinking, chewing and swallowing are mechanical in nature, I have no doubt that some people are more affected by swallowed air than others. 

The condition of swallowing excessive air is called aerophagia, and it's been confirmed to be a real thing for people suffering from excess gas. That's not to say that fibre, fizzy drinks, or indigestion may not contribute to excess gas, but swallowed air seems to play a big role for some people.

I don't notice that I swallow air, even when consuming soup, at least not in a way that causes me to burp or have gas. But I can see how this might cause swallowed air to turn into excess gas for someone else who may have a slightly different way of eating or has some differences (mechanically) in how they swallow. 

Interestingly enough, the main treatment for aerophagia is often behavioural change, so it may not be the act of swallowing that causes the problem, but how we swallow.
