Liver transplantation is associated with a rapid decrease in bone mineral density at the proximal femur further increasing fracture risk and a reduction in lean muscle mass which may also predispose to falls.

. Menopause is associated with an increase in abdominal fat and a significant increase in the risk of cardiovascular disease and accelerated loss of bone mass. Accelerated Bone Mineral Loss Following a Hip Fracture. Bone loss in both sexes are caused by increased osteoclastogenesis the natural process of bone breakdown that has now accelerated caused by estrogen deficiency.

Eighty-three elderly patients mean age 77. Aging men and women are subject to two distinct types of bone loss mechanisms. Receptors for thyroid hormones and TSH are present in bone.

In hyperthyroidism bone turnover is accelerated two-fold with a net loss of bone. The purpose of this prospective study was to monitor the bone mineral density BMD of the lumbar spine and contralateral femoral neck in the first year following an osteoporosis-related fracture of the hip. In addition high alcohol intake is associated with increased bone loss falling and fractures in older men.

These hormones may act directly on both osteoclasts and osteoblasts. Calcium and vitamin D deficiency may increase the possibility of suffering from accelerated bone mass loss. Patients with end-stage liver disease have reduced bone mineral density.

Furthermore we show that OPGFc treatment results in accumulation of osteomorphs that are able to reassemble rapidly into large activated osteoclasts upon OPGFc withdrawal resulting in bone loss. These findings mirror the accelerated bone loss and spontaneous fractures recently described following discontinuation of treatment with. The severity of hyperthyroidism correlates with the decrease in BMD and the increase in fracture risk.
