Osteoporosis is a common complication in IBD. In a retrospective study of patients with IBD (59 men, 115 women), 38.5% had impaired bone mineral density. Furthermore, men were diagnosed more often with osteopenia or osteoporosis than women (55.9% versus 29.6%), with a risk of bone disease comparable to postmenopausal women. Men with IBD are therefore also at high risk of osteoporosis, particularly when treated with corticosteroids, and might warrant careful monitoring.
