The researchers suspect low testosterone levels in men suffering from eating disorders. Men who suffer from eating disorders can be affected more than women with the same problems, researchers say.
Eating disorders are associated with a weakening of the bones, which become dangerously thin and brittle. This is linked to severe weight loss and lack of essential nutrients, particularly calcium.Low bone mineral density (BMD) can lead to osteoporosis, and an increased risk of fracture.
The researchers pointed out that men with low BMD needed to be warned about exercise limitations to prevent fractures. They added: "On the other hand, moderate weight-bearing exercise without high impact aids in bone accretion, in addition to calcium and vitamin D intake."
