Soda is famously acidic, with a pH around 2.5 to 3.5. For reference, that’s almost as acidic as stomach acid itself. When you drink it, you’re dumping a mild acid bath directly into your digestive tract.
For some people, this acid irritates the lining of the stomach and esophagus. It can trigger heartburn, acid reflux, or a sharp burning pain right under your ribs. If you already have a condition like gastritis or IBS, soda is basically pouring lighter fluid on a campfire. (Not recommended, please don’t try this at home.)

The Artificial Sweetener Trap
“But I drink diet soda!” you protest, clutching your zero-calorie can. I hear you, friend. But diet sodas swap sugar for artificial sweeteners like aspartame, sucralose, or sorbitol. Your body doesn’t fully recognize these fake sugars.
Many people can’t digest them properly, leading to a lovely cascade of gas and osmotic diarrhea. Sorbitol, in particular, is a known gut irritant. So your “healthy” choice might actually be the one making your stomach explode like a shaken soda can. Oh, the irony.
