2.3.1 Risk factors for developing osteoporosis

The majority of cases of osteoporosis in women relate to relatively low peak bone mass achieved in youth. This is usually genetically determined along with normal menopause and normal ageing, as well as a sedentary lifestyle or a less healthy diet. However, other conditions and factors may be important drivers of bone loss, which can then be called secondary osteoporosis. Where there are other important medical factors, patients may benefit from further investigation, either by their GP or a specialist such as a geriatrician or a rheumatologist. In the general population of men with osteoporosis, if investigating for secondary causes, you are more likely to find one than not. Examples of such causes are listed in the table below.

Examples of secondary causes of osteoporosis:
type 1 diabetes mellitus
untreated longstanding thyrotoxicosis
hypogonadism or premature menopause (below age 45)
chronic malnutrition
malabsorption
liver disease
glucocorticoid use
alcohol excess
