Follow-up

Complications

  • Osteopenia

Prognosis

  • The prognosis of patients with lactose intolerance is excellent with dietary restrictions.

Patient Education

  • Instruct patients to read labels on commercial products.
  • Whole milk and chocolate milk may be better tolerated than skim milk.

Miscellaneous

Medicolegal Pitfalls

  • Lactose intolerance is not lethal and morbidity is low, although osteopenia can be a complication of this disorder. Failure to adequately counsel the patient and to provide proper treatment could lead to medicolegal liability.
