What could be causing my stomach to hurt whenever I drink sodas with caffeine in it? Like Coke or Pepsi. I would always drink Pepsi but one day my stomach started hurting multiple time after drinking it.
You can check the answer of the people under the question at Quora “stomach hurting after drinking coffee“
You probably have an ulcer, and the cola is irritating it. It wouldn’t have anything to do with caffeine directly, but may be related to recipe of the soda (many of which are fairly acidic.)
I know exactly what you are talking about and guess what? It isn’t the caffeine. Tea has caffeine and I would just about bet that it doesn’t hurt your stomach.
Why?
Because it is the acidity of cola beverages that makes you sick.
Drink coffee. You will be sick not due to caffeine but due to the low pH of the coffee. Your stomach has a very acidic environment due to the pepsin and hydrochloric acid in it. Coffee is very acidic and in that acidic environment of your stomach you will be sick.
So, if you must drink soda, drink ginger ale. Not artificial ginger ale, but with real ginger in it.
I have also found that boylan’s root beer does not make me sick. Stewart’s is good too, if you can find it.
