Abstract

Studies that evaluate the influence of gastric bypass (RYGP) on bone mass are limited to short-term follow-up. We analysed changes in bone mineral density (BMD) three years after surgery and evaluated the main determinants of the development of bone disease. Prospective study of 59 morbidly obese white women aged 46 ± 8 years. BMD scanning using DEXA and plasma determinations of calcium, parathyroid hormone, 25-hydroxyvitamin D and insulin-like growth factor-I were made prior, at 12 months and 3 years after surgery. In the first postoperative year BMD decreased at femoral neck (FN) 10.2 % and in the lumbar spine (LS) 3.2 %, in the third year it additionally decreased 2.7 % and 3.1 %, respectively. BMD at both sites remained above the values of women of the same age. In the follow-up, 1.7 % developed osteoporosis at FN and 6.8 % at LS. Patients with bone disease were older, the percentage of women with menopause was greater in this group and had lower initial and final values of lean mass. The percentage of BMD loss at FN remained positively associated with the percentage of lean mass loss [β 0.304, p=0.045], and menopause [β 0.337, p=0.025]. Major osteoporotic fracture and hip fracture risk was low even in menopausal patients (3.1 % and 0.40 %, respectively). After RYGP menopausal women and those with greater lean mass loss are at higher risk of BMD loss but progression to osteoporosis is uncommon and the risk of fracture is low.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
