Osteoporosis (bone thinning) is defined by the WHO World Health Organisation as bone mineral density of more than 2.5 standard deviations below the mean value for peak bone mass in young adults – measured by dual energy x ray absorptiometry (DEXA). It has been discovered that high rates of Osteoporosis (bone thinning) in “Schizophrenia” may result from the prolactin raising effects of some anti psychotics. Prolactin is a protein secreted by the pituitary gland. Osteoporosis is hereditary. So, if you’re taking anti psychotic medication or have taken it in the past, it’s surely worth going to your Doctor to discuss this link. I’ve searched the NHS Choices website to see if Osteoporosis is listed as a side effect of anti psychotics but haven’t found any information. I’ve contacted DataPharm, who provide the information, for their comment. More soon.
