About Claes Ohlsson

Claes Ohlsson is Professor (2000-) and Head of the Department of Internal Medicine and Clinical Nutrition at the Institute of Medicine, Sahlgrenska Academy at University of Gothenburg. In addition, he is senior physician at the Sahlgrenska University Hospital in Gothenburg.


His research within the field of osteoporosis has a translational profile, combining cell and molecular biology with experimentation on animals and human tissues, as well as randomized clinical trials. His research is mainly focused on the hormonal regulation of bone growth and metabolism, and more recently, the genetics of bone mass and fractures. He has received several prestigious awards.

The following recent major findings are further evaluated in his ongoing research:

He has in translational studies identified a new mechanism for the regulation of cortical bone mass and fracture susceptibility. This finding opens up novel avenues for specific prevention or treatment of non-vertebral fractures, a significant and unmet medical need.(Nature Medicine 2014;20 (11):1279-88)

He demonstrated that the gut microbiota is a major regulator of bone mass and this finding opened up a completely new research field. This is a true translational project, starting with experimental studies of the skeleton of germ free mice and probiotic treated mice, followed by a large multicenter randomized clinical trial, demonstrating that probiotic modulation of the gut bacteria composition prevented postmenopausal bone loss in the spine (JBMR2012, 27:1357; Trends Endocrinol Metab. 2015 26:69; Lancet Rheumatology 2019 in press)

He has in collaborative studies characterized the genetics of osteoporosis and fracture susceptibility. (Nature2015, 526(7571):112; PLoS Genet 2010, Nov;6(11):e100121; Nature Genetics 2012, 44:491; PLoS Genet 2013, Feb;9(2):e1003247; BMJ 2018, 362:k3225; Nature Genetics 2019 in press)

He has identified a leptin-independent homeostatic regulation of body weight (“gravitostat”), depending on body weight sensing in rodents and he has recently in a translational human randomized clinical trial demonstrated that increased weight loading reduces body weight and body fat in obese subjects. (PNAS2018, 115:427; Endocrinology 2018, 159:2676; Endocrinology 2019, 160:1057; Ohlsson et al manuscript).
