While low body mass index (BMI) is a risk factor for fractures, the association between obesity and fracture risk is inconsistent and puzzling. Several studies reported higher fracture risk (FR), and others reported lower FR in obese populations. Our narrative review presents the overall incidence of fractures by anatomic locations in adult patients, geriatric populations, and in those after bariatric surgery. In conclusion, obesity should be considered as a fracture risk in adults, as well as falls and fractures in geriatric patients, in particular in those with sarcopenic obesity, and after bariatric surgery. The specific characteristics of fractures risk associated with obesity should be considered by physicians in the diagnostic and therapeutic work-up of obese patients. This review outlines the current literature on this topic and aims to guide physicians regarding proper decisions to prevent fractures in patients with obesity.
