Osteoporosis is a common disease in the elderly. Bones become less dense and more likely to break. Treatment of osteoporosis frequently falls under endocrinologists.
List two hormones that impact osteoporosis.
Explain how each one affects bone density.
Why does the release of cortisol during the stress response have a negative effect on bone density?
Cortisol increases serum calcium to fuel muscle contraction during the fight or flight responseCortisol reduces estrogen production and triggers early menopause
Cortisol draws calcium out of the bones to increase serum calcium to fuel muscle contraction during the fight or flight response
Cortisol decreases calcium to fuel muscle contraction during the fight or flight response
