Sometimes, the water isn’t the villain—it’s what’s inside your stomach already. You might have acid reflux or GERD without realizing it. When you drink water, it can stir up stomach acid like stirring a muddy puddle with a stick.
That acid can splash up into your throat, and your body thinks: “Nope, we’re evacuating!” It’s not the water—it’s the acid party you didn’t know was happening.
If this happens often, a quick chat with your doctor or a glass of alkaline water might help. Or just eat something before you hydrate.
