Epilepsy and osteoporosis are very common and frequently overlap. Nevertheless, the prevalence of low bone density appears to be disproportionately higher in patients with epilepsy, and patients with epilepsy have an excessive risk of fractures. A meta-analysis of 94 cohort studies and 72 case-control studies has shown that anticonvulsant treatment is highly associated with fractures (relative risk over 2) (117). Other risk factors were low body weight, weight loss, physical inactivity, consumption of corticosteroids, primary hjrperparathjroidism, type 1 diabetes melhtus, anorexia nervosa, gastrectomy, pernicious anemia, and age over 70 years.

The risk of developing anorexia nervosa in female twins is higher than in male twins, as expected from the female/male ratio among adults in general. But an exception is the male member of an opposite-sex twin pair. Such males have a higher risk of developing anorexia nervosa when compared with other males—the risk at a level not significantly different from that of their twin sisters.67 The most reasonable conclusion is that the male twin in an opposite-sex twin pair is exposed to a hormone or hormones dependent on the presence of a female fetus in the womb—and the exposure is a risk factor for anorexia nervosa.
