Clearance of a substance is sometimes expressed as the inverse of the time constant that describes its removal rate from the body divided by its volume of distribution (or total body water). In steady-state, it is defined as the mass generation rate of a substance (which equals the mass removal rate) divided by its concentration in the blood .
A person begins drinking oral rehydration solution (ORS) to prevent dehydration and electrolyte loss. This strategy adds modest amounts of sugar and salt to water. There are prepackaged ORS products available. A person can also use home products such as lightly salted soup or lightly salted water from the cooking of rice. [1] [2]
This happens because the kidney is unable to efficiently retain water while excreting large amounts of sodium. In addition, after sodium excretion, the osmoreceptor system may sense lowered sodium concentration in the blood and then direct compensatory urinary water loss in order to correct the hyponatremic (low blood sodium) state.
In 1831, William Brooke O'Shaughnessy noted the changes in blood composition and loss of water and salt in the stool of people with cholera and prescribed intravenous fluid therapy (IV fluids). The prescribing of hypertonic IV therapy decreased the mortality rate of cholera to 40%, from 70%. In the West, IV therapy became the "gold standard ...
The recommended daily amount of drinking water for humans varies. [1] It depends on activity, age, health, and environment.In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20 ...
Salt poisoning is an intoxication resulting from the excessive intake of sodium (usually as sodium chloride) either in solid form or in solution (saline water, including brine, brackish water, or seawater). Salt poisoning sufficient to produce severe symptoms is rare, and lethal salt poisoning is possible but even rarer. The lethal dose of ...

The recommended adequate intake of sodium is 1,500 milligrams (3.9 g salt) per day, and people over 50 need even less." [13] The Daily Value for potassium, 4,700 mg per day, was based on a study of men who were given 14.6 g of sodium chloride per day and treated with potassium supplements until the frequency of salt sensitivity was reduced to 20%.
