Abstract
Postgastrectomy bone disease was a term devised to describe the metabolic disorders of bone which may follow a gastrectomy operation. Although the use of this operation has declined drastically in recent years, this metabolic bone disorder is still with us and may escape and confuse the unwary. These disorders may take the form of osteomalacia, osteoporosis in excess of normal ageing, or a combination of both. For screening purposes, regular estimations of plasma alkaline phosphatase levels identify patients who may be developing osteomalacia which can then be treated with calcium and vitamin D supplements. Numerically, osteoporosis in excess of ageing is a bigger problem and its prevention and treatment is at present unsatisfactory. Screening procedures for osteoporosis are reviewed, including the more recent methods of bone mineral density assessment. Osteopenia or demineralization occurs in both osteomalacia and osteoporosis therefore osteomalacia must be excluded before attributing any loss to osteoporosis. The present situation with regards to the prevention and treatment of osteoporosis is also reviewed.
