Overview

If left untreated, patients with lactose intoelrance may progress to develop malnutrition, osteomalacia , and osteopenia. Common complications of lactose intoelrance include if they do not intake calcium

include osteoprosis, osteopenia, osteomalacia and malnutriotion. Prognosis is generally excellent.

Natural History, Complications, and Prognosis

    • Watery, frothy and bulky diarrhea
  • If left untreated, patients with lactose intolerance may progress to develop:
    • Malnutrition
    • Osteomalacia
    • Osteopenia

Complications

  • Common complications of lactose intolerance if they do not intake adequate quantities of dairy products and calcium include: [4][5][6]
