Bone Loss 3-5+ years post surgery in POST-Operation Weight Loss Surgery Q&A Posted September 12, 2020 I’ve come across some scary research that states a high rate of bone loss among bariatric surgery patients. It said that the bone loss is prominent around 3-5+ years post surgery. This concerns me. I thought Calcium supplementation and weight bearing exercises should help avoid and issues. Has anyone come across this? Or if you are 3-5+ years out have you experienced it?
