Is it true that lactose intolerance causes stomach pain after consuming dairy products?
Yes. Multiple sources, including a clinic page and peer-reviewed reviews, state that lactose intolerance causes stomach pain or abdominal pain after consuming dairy or lactose-containing foods. A small student study and a probiotic meta-analysis also report abdominal pain among lactose intolerance symptoms.
