I've heard that some people get a stomach ache after drinking milk. Is that true?

Yes, it is possible to have a stomach ache from drinking milk. It's caused by lactose intolerance, which means your body doesn't produce enough of the enzyme lactase to break down the sugar in milk. Symptoms can include bloating, gas, diarrhea, and cramps. You can reduce symptoms by avoiding dairy products or taking an over-the-counter supplement containing lactase.
