Risk factors you cannot change
Gender. Your chances of developing osteoporosis are greater if you are a woman. Women have less bone
tissue and lose bone faster than men because of the changes that happen with menopause.
Age. The older you are, the greater your risk of osteoporosis. Your bones become thinner and weaker as you age.
Body size. Small, thin-boned women are at greater risk.
Ethnicity. Caucasian and Asian women are at highest risk. African American and Hispanic women have a lower but significant risk.
Family history. Fracture risk may be due, in part, to heredity. People whose parents have a history of fractures also seem to have reduced bone mass and may be at risk for fractures.
Risk factors you can change:
Sex hormones. Abnormal absence of menstrual periods (amenorrhea), low estrogen level (menopause), and low testosterone level in men can bring on osteoporosis.
Anorexia nervosa. Characterized by an irrational fear of weight gain, this eating disorder increases your risk for osteoporosis.
Calcium and vitamin D intake. A lifetime diet low in calcium and vitamin D makes you more prone to bone loss.
Medication use. Long-term use of certain medications, such as glucocorticoids and some anticonvulsants can lead to loss of bone density and fractures.
Lifestyle. An inactive lifestyle or extended bed rest tends to weaken bones.
Cigarette smoking. Smoking is bad for bones as well as the heart and lungs.
Alcohol intake. Excessive consumption of alcohol increases the risk of bone loss and fractures.
