- 1Calcium functionsBone growth, development, maintenance
blood clot formation
muscle contraction - 2additional calcium functionlowers risk of bone fractures
lowers risk of colon cancer
lowers risk of kidney stone formation
lowers BP
improve lipid profile - 3Getting enough calciumRule of 300s- estimate calcium need
- 4Calcium DeficiencyDecreased bone mineral density which can lead to osteopenia, osteoporosis
Low blood Calcium which can cause high BP, muscle cramps, abnormal heart rhythm - 5Very high intake of calcium canincrease risk of kidney stones
headaches
kidney failure
tissue calcification
decreased absorption of other minerals - 6Regulation of Blood CalciumSecretion of parathyroid hormone (PTH)
Secretion of calcitonin - 7Type 1 osteoporosis(postmenopausal)
affects trabecular bone undergoing rapid remodeling - 8Type 2 Osteoporosisbreakdown of cortical bone and trabecular bone
- 9Vitamin D functionsRegulates calcium absorption in three ways:
1. from small intestine
2. with PTH and calcitonin to regulate calcium secretion via kidney
4. bone remodeling - 10Vitamin D deficiencyRickets
