The document discusses lactose intolerance, which is the body's inability to digest lactose sugars found in milk due to a lack of the enzyme lactase. Symptoms include bloating, diarrhea, abdominal cramps and gas. It is not a milk allergy but a common digestive condition. To cope, one can consume yogurt, dairy in small amounts with other foods, lactose-free dairy, or high calcium alternatives. Over-the-counter lactase enzymes or seeing a doctor may also help manage the condition.
