Ironically, some people swear by Coca-Cola as a remedy for stomach bugs. It’s a weird cultural flex—like the Thai street-food habit of sipping warm Coke for indigestion. The sugar and caffeine can give a quick energy boost, and the phosphoric acid might settle gas. But for diarrhea? Proceed with caution.
In many countries, “Coke and crackers” is the unofficial treatment for a queasy stomach. But let’s be real: if you already have diarrhea, drinking a sugary, acidic soda is like pouring gasoline on a fire. The sugar will worsen dehydration, and the caffeine can act as a diuretic, making you lose even more water.
