Obesity surgery
-
Metabolic bone disease is a well-documented long-term complication of obesity surgery. It is often undiagnosed, or misdiagnosed, because of lack of physician and patient awareness. Abnormalities in calcium and vitamin D metabolism begin shortly after gastrointestinal bypass operations; however, clinical and biochemical evidence of metabolic bone disease may not be detected until many years later. ⋯ This case illustrates not only the importance of informed consent in patients undergoing obesity operations, but also the importance of adequate follow-up for patients who have undergone these procedures. A thorough history and physical examination, a high index of clinical suspicion, and careful long-term follow-up, with specific laboratory testing, are needed to detect early metabolic bone disease in these patients.
