[Osteoporosis and multimorbidity].

Osteoporosis is a systemic bone disease with decreased bone strength and mass resulting in an increased predisposition to fracture risk. Especially older patients have a high risk for fragility fractures. In these patients an isolated view of osteoporosis without consideration of multimorbidity is insufficient. Various diseases are associated with osteoporosis because of shared pathophysiological mechanisms, risk factors or as a consequence of medication. Furthermore, geriatric syndromes, such as falls play an importance role. This article presents an overview about multimorbidity interactions based on selected frequent diseases in older age and shows the management in the clinical practice.
