How Age factors Affecting the calcium absorption?
Age is another factor which influences the absorption of calcium. Fractional absorption of calcium is highest in infancy i.e., 6O%, followed by the early pubertal period. One study found 28% calcium absorption in pre pubertal children that increased to 34% in early puberty returning to the adult value of 25% two years later. Absorption of calcium is also increased in pregnancy to levels higher than 25% reported for adults. Available data suggests that in post menopausal women, absorption declines by 0.21% every year. Thus, from 50 years to 70 years, absorption may decline by 4%. Ageing also reduces renal losses of calcium, due to reduced absorption and decrease in filtered calcium load.
