Skeletal Health in Bariatric Surgery Patients

Summary

The investigators propose a prospective cohort trial that will help to understand the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in pre- and post-menopausal female bariatric patients.

Conditions

Interventions

PROCEDURE

Roux en Y Gastric Bypass Pre-menopausal

The investigator aims to determine changes in skeletal health after Roux en Y Gastric Bypass in pre-menopausal women. Dual-energy x-ray absorptiometry (DXA) will be used to assess bone mineral density (BMD), including assessment for fracture risk (FRAX). Trabecular Bone Score (TBS) software will be used to adjust FRAX scores for bone microstructure and an enhanced fracture risk probability. Biochemical markers of bone metabolism and calcium homeostasis including serum bone alkaline phosphatase (BALP), osteocalcin, type 1 procollagen (P1NP), c-terminal telopeptide (CTX), calcium, albumin, parathyroid hormone (PTH), and 25-OH vitamin D will be assayed.

PROCEDURE

Roux en Y Gastric Bypass Post-menopausal

The investigator aims to determine changes in skeletal health after Roux en Y Gastric Bypass in post-menopausal women. Dual-energy x-ray absorptiometry (DXA) will be used to assess bone mineral density (BMD), including assessment for fracture risk (FRAX). Trabecular Bone Score (TBS) software will be used to adjust FRAX scores for bone microstructure and an enhanced fracture risk probability. Biochemical markers of bone metabolism and calcium homeostasis including serum bone alkaline phosphatase (BALP), osteocalcin, type 1 procollagen (P1NP), c-terminal telopeptide (CTX), calcium, albumin, parathyroid hormone (PTH), and 25-OH vitamin D will be assayed.
