Extracts from age-related glandular disorders Fluid and electrolyte imbalance: With age, the response to the antidiuretic hormone (ADH) increases, causing a decrease in the kidney's ability to excrete water. Renal clearance decreases at an average of 8 ml/min/1.73 m for every 10 years after age 30. The sensitivity of the kidney to aldosterone in relation to sodium decreases. It decreases or rises according to the controlling factor - blood sodium decreases often in hospitalized patients, those taking diuretics, and cancer patients Symptoms of hyponatraemia agitation, convulsions and lethargy - sodium increases in the elderly due to the weak sense of thirst where thirst is stimulated when plasma osmolality >292 ml osmol/kg water, While at older ages, it is provoked with an osmolality higher than 296, so in any disturbance of consciousness in the elderly, do not forget to check blood electrolytes..
