Your body is not built for a sugar flood. A typical 12-ounce soda has about 39 grams of sugar—that’s almost 10 teaspoons. Your intestines look at that and say, "Nope, I’m out." They start pulling in extra water to dilute the sugary mess, which can trigger diarrhea or cramping.
One study found that people who drink soda regularly have a 65% higher risk of developing digestive issues like bloating or acid reflux. You aren’t imagining it; your stomach is literally running a protest.

Diet soda is not your savior—it’s a trickster
Artificial sweeteners like aspartame and sucralose are basically sugar’s weird cousins who show up uninvited. They pass through your gut undigested, then your gut bacteria throw a raucous party and fart out gas. The result? That same bloating and discomfort, but without the calories.
Surprising twist: Some people’s gut bacteria react to diet soda by producing methane. Yes, methane. You are essentially turning your stomach into a miniature, gassy swamp.
