Question

dont let this happen to you
in some people, the rate of bone resorption can prematurely exceed that of bone formation during periods of prolonged inactivity, such as a patient confined to bed rest or someone with a spinal cord injury who can no longer walk. this condition is known as disuse osteoporosis. disuse is not only limited to these conditions. anyone who does not get enough exercise (walking counts) puts themselves at risk for reduced bone mass and disuse osteoporosis. this can be especially harmful for children during the years of bone formation.

1. what is osteoporosis and what causes it?
2. who is more likely to be affected by osteoporosis and at what age?
3. what are risk factors?

Explanation:

1. Osteoporosis is a condition where bone resorption can exceed bone formation, especially with inactivity like being bed - ridden or having limited mobility. Causes include lack of exercise during bone - forming years (harmful for children) and inactivity due to injury or medical conditions.
2. Women, the elderly (especially post - menopausal women), people with a family history of osteoporosis, those with certain medical conditions (like hormonal imbalances), and individuals with low body weight are more likely to be affected. The risk generally increases with age, especially after menopause for women.
3. Risk factors include inactivity (disuse osteoporosis as described), poor diet (low in calcium and vitamin D), smoking, excessive alcohol consumption, certain medications (e.g., corticosteroids), family history, low body weight, and hormonal changes (such as menopause in women and low testosterone in men).

Answer:

1. Osteoporosis is a condition where bone resorption can prematurely exceed bone formation, especially with inactivity. Causes include lack of exercise during bone - forming years and inactivity due to injury or medical conditions.
2. Women, the elderly (especially post - menopausal women), those with a family history, people with certain medical conditions, and low - weight individuals are more likely to be affected. Risk increases with age, especially after menopause for women.
3. Inactivity, poor diet, smoking, excessive alcohol, certain medications, family history, low body weight, and hormonal changes are risk factors.
