I don't know really, but I drink a lot of diet drinks, and diet dr. pepper usually doesn't do it, but like coke zero and diet coke make my stomach feel crazy. It hurts.

Sodas bother me badly. i hear that any acid reflux or gerd that sodas will irritate it due to the carbonation. I dont know my problem either but i know everytime i quit sodas i get better but when i go back on them the problem comes back.

What happens when you drink sparkling water? Maybe it's the carbonization that is hurting you.

Next time you need to drink soda, try Charco-Caps. They help absorb gas. I have hernia issues and I too have a problem with carbonation. My stool is described similar to yours. Charco-Caps Homeopathic are really kind on me too. Doesn't make me sick or anything. Hope this helps

ahhhh i would say run from sodas, aspartme and artificial sweeteners, these are bad for you. i would encourage you to look up the products rthat are in your drinks.

we had a hyperactive very difficult child, this is what got me started on looking into what is in our foods. we are wining now and no drugs.
our food is so important, poor health stats are so scarey, what has changed this last 2 generations. there is so much rubbish in the products we consume. what ever happened to natural.

i was generally looking into my toothpaste products, the same ingredients are used in industrial pesticides and car antifreeze, and i give this to my children with a big warning, do not swallow!!!if swallwed contact the poisons centre.

I am seriously concerned at what is in our food, we are back to pure form as much as possible, i want to have a good longterm healthy life, but thats only going to happen by making wise choices. baby steps. we have sodas but they are a rare treat at birthdays etc..
my son and husband have an allergy to sodium nitrate(in bacons-preserved meats) scarey stuff, i found through a process of elimination. well both of them if they have bacon or sausages will be so angry, hostile, impulsive ,offensvie, nasty and just no be able tocope for upto 3 days.
this is not a food for us, its a preservative and it interferes with normal cell death, mutations are formed and replicate, i read this in a medical book(thankyou god for a hyperactive child who made it so difficult for many years that made me look into what is in our food.

hope this helps someone.

This has happened to me about 3-4 times and it's always from Dr. Pepper. I haven't passed out but I've gone into tunnel vision with loss of my peripheral vision and could no longer hold myself up.
I was in fear that this was stomach ulcers. But my doctors assure me it is not. My doctor told me that it's possibly some kind of reaction to all the carbonation and caffeine along with the sugars in these drinks that can cause this, but there has been no definitive answer as of yet.

I find drinking clear sodas such as Sprite and Mountain Dew or Canada Dry can actually cure stomach pains and discomfort, more so the Sprite and Canada Dry as opposed to Mountain Dew(a lot of caffeine).

Soda's bad for you anyways and this just helped me to realize that even more. Just juice and water and an occasional Sprite for me from now on!
