What are the symptoms of lactose intolerance?

    Lactose intolerance causes undigested lactose to build up in the large intestine, resulting in the growth of gas-producing gut bacteria. Symptoms include:

    • Bloating
    • Flatulence
    • Diarrhea
    • Nausea
    • Vomiting
    • Abdominal pain or cramps
    • Gurgling and rumbling sounds from the abdomen
