Bone density significantly decreases three years after total gastrectomy, linked to lower vitamin D levels. Weight loss is a key indicator for early detection of these bone disorders.

Area of Science:

  • Endocrinology
  • Bone Metabolism
  • Gastroenterology

Background:

  • Gastrectomy can lead to significant bone density loss.
  • Early detection of post-gastrectomy bone disorders is crucial for patient management.

Purpose of the Study:

  • To investigate bone mineral density changes and related factors following total gastrectomy.
  • To identify reliable early markers for post-gastrectomy bone disorders.

Main Methods:

  • Assessed bone mineral density (Wards triangle), serum 1,25-(OH)2-D, alkaline phosphatase, and calcium in gastrectomy patients.
  • Compared bone density and vitamin D levels at baseline (A1) and three-year follow-up (A2).
  • Correlated bone density with weight loss and vitamin D levels.

Main Results:

  • Bone density significantly decreased from A1 to A2 (P < 0.01).
  • Serum 1,25-(OH)2-D levels were significantly lower in A2 compared to A1 (P < 0.01).
  • Weight loss correlated negatively with bone density (r = -0.74, P < 0.01), and 1,25-(OH)2-D correlated positively (r = 0.67, P < 0.01).

Conclusions:

  • Bone density loss occurs within three years post-gastrectomy.
  • Vitamin D deficiency is associated with reduced bone density after gastrectomy.
  • Weight loss is a valuable screening parameter for early detection of bone disorders, unlike alkaline phosphatase and calcium levels.
