Minor cases of the runs can be the result of:
Overeating Nerves Minor viral infections Alcohol overindulgence A side effect of medication Eating food that’s just begun to spoil Lactose intolerance (which means your stomach’s digestive acids lack the enzyme that will properly digest the sugar in milk, causing gas, heartburn, and diarrhea) Taking too many antacids (which translates into too much magnesium and, ultimately, watery stools)

But there are times when diarrhea can signal more serious illnesses—or lead to illness itself. These sections describe situations you should be mindful of, so you know when to seek expert care.
