Glomerulání filtration, as assessed by creatinine clearance yet may fall by up to 1 / 3 of the original value. This decline, however, in about one-third of people is absent, so it can not be clearly attributed to the expense of involution. Besides the decline in glomerular function with age decreases renal perfusion, tubular resorption (eg, glucose, sodium), concentration and dilution capacity of the kidneys. In the old tehre is rising tendency to loss of water and sodium (decreased ability to re-absorption of sodium) along with the rise in serum potassium. Serum creatinine due to a decrease in overall muscle mass may have less value than a notice in younger patients |
