Lactose intolerance
Question: Is it possible to suddenly develop an intolerance to lactose?
Answer: Most people do. That is, most children do not have lactose deficiency until the age of
three or so (there are some exceptions). The deficiency develops as one ages. The degree of the
deficiency will predict when symptoms will be seen – most in their early childhood – some not
until their adult years. Lactose deficiency can also occur in sprue, after bacterial infections
of the bowel, and with inflammatory diseases of the bowel like ulcerative colitis or crohn’s
disease.
