Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research study is to see whether receiving a bisphosphonate medication called risedronate can reduce bone and muscle loss following bariatric surgery. Participation will involve up to 6 study visits and last about 1 year. Risedronate is a medication that prevents bone breakdown and has been approved by the US Food and Drug Administration (FDA) for the prevention and treatment of osteoporosis in older men and women. However, risedronate has not been approved for the prevention of bone and muscle loss following vertical sleeve gastrectomy. Participation in this study will involve completing two visits before beginning the intervention. Participants who qualify will be scheduled to begin the intervention program which will involve taking 6 monthly doses of a risedronate or placebo pill. Participants will then receive monthly contacts by study staff during this time to remind participants to take the intervention pill and ask about any adverse events. After the completion of intervention period, participants will complete up to 4 follow up study visits at 6 months (2 visits) and at 12 months (2 visits).
