1 Lactose intolerance is caused by a deficiency of the intestinal enzyme lactase that splits lactose into two smaller sugars, glucose and galactose, and allows lactose to be absorbed from the intestine.  The primary symptoms of lactose intolerance are diarrhea, flatulence (passing gas), and abdominal pain. Abdominal bloating, abdominal distention, and nausea also may occur.
10 Signs of Lactose Intolerance. Lactose intolerance is a common digestive condition where the body is unable to digest lactose, a natural sugar that is found in milk and dairy products. During a normal digestion, lactose is broken down by an enzyme called lactase into glucose and galactose. People with lactose intolerance do not produce enough of lactase; so lactose stays in the digestive system where it is fermented by the gut bacteria resulting in the production of gases.
