In cases of water intoxication, it is extreme hyponatremia that can ultimately cause coma and death. If it's caught early, treatment with IV fluids containing electrolytes can lead to a complete recovery; but untreated, hyponatremia is fatal.
Full Answer
What is water intoxication and how is it treated?
What Is Water Intoxication? The definition of water intoxication is: “A lowered blood concentration of sodium ( hyponatremia) that occurs due to the consumption of excess water without adequate replacement of sodium.” ( 1)
What is water intoxication in correctional settings?
Considered a rare condition in the general US population, water intoxication, also called psychogenic polydipsia (PPD), can happen more frequently in correctional settings. Correctional nurses and our officer colleagues need to be aware of this condition and act quickly to save lives.
What is the pathophysiology of water intoxication?
Water intoxication provokes disturbances in electrolyte balance, resulting in a rapid decrease in serum sodium concentration and eventual death. The development of acute dilutional hyponatraemia causes neurological symptoms because of the movement of water into the brain cells, in response to the fall in extracellular osmolality.
Why are some people more likely to experience water intoxication?
Some people are more likely than others to experience water intoxication. Infants have a lower body mass and are more susceptible to excessive intake of fluids. Patients on intravenous fluids are carefully monitored for blood levels of minerals and water to keep everything in check.

How long does it take to recover from overhydration?
According to nephrologist Dr. John Maesaka, the kidney can only excrete up to 1 liter an hour. This means that if you are severely overhydrated, it will take a few hours after water intake has stopped for the body's hydration levels to return back to normal, even if a diuretic is taken.

How is water intoxication treated in dogs?
Treatment Options The primary goal with treating acute water intoxication is to raise the plasma sodium concentration; typically, this is done no faster than 0.5-1 mEq/L per hour. However, if patients are showing severe symptoms in an acute situation, this rate may need to be faster.
How do diuretics work in dogs?
Furosemide is a diuretic (a drug that increases urine production). It stimulates the kidneys to produce more urine and remove excess fluid from the body. This relieves the work your dog's heart has to do. It also relieves fluid collection in the lungs that can be life-threatening.

Symptoms of over-hydration (water intoxication) include staggering/loss of coordination, lethargy, nausea, bloating, vomiting, dilated pupils, glazed eyes, light gum color, and excessive salivation. In severe cases, there can also be difficulty breathing, collapse, loss of consciousness, seizures, coma, and death.
What happens to your cells during water intoxication?
The mechanism of water intoxication is associated with osmotic pressure in cells. At decreasing amounts of salt in the blood, cells adjust by taking up more and more water. Consequently, the cells will swell. If this leads to transport of high amounts of water to the brain it may be extremely harmful.
How does water intoxication cause increased intracranial pressure?
Thus the amount of intracellular water increases, causing the cells to swell. In the CNS, the swollen neurons increase the intracranial pressure which leads to the symptoms of confusion, lethargy, headache, and drowsiness.
How does water intoxication affect the brain?
This causes the cells to swell. The swelling increases intracranial pressure in the brain, which leads to the first observable symptoms of water intoxication: headache, personality changes, changes in behavior, confusion, irritability, and drowsiness.

Symptoms of advanced water intoxication include seizures, coma, respiratory arrest, brain stem herniation, and death. Even if hyponatremia is caught and treated, there can be long term conditions that result from the brain damage.
How much water can the kidneys excrete?
While the kidneys can excrete 0.25 gallons of water an hour during a normal physiological state, high vasopressin secretion can reduce this to 100 milliliters per hour. With that reduced volume of water being filtered through the kidneys, excessive water intake can be even more dangerous than usual.
Why is hyponatremia dangerous?
Hyponatremia is dangerous because it can lead to edema, or swelling of the cells. When there is excessive water in the blood stream that can’t be filtered by the kidneys quickly enough, this water passes into the cells and exceeds the sodium-water balance.

When an unconscious person is being fed intravenously, what is the fluids given?
When an unconscious person is being fed intravenously (for example, total parenteral nutrition) or via a nasogastric tube, the fluids given must be carefully balanced in composition to match fluids and electrolytes lost. These fluids are typically hypertonic, and so water is often co-administered. If the electrolytes are not monitored (even in an ambulatory patient), either hypernatremia or hyponatremia may result.

But when a large quantity of pure water is ingested, the kidneys can't eliminate it fast enough, so water builds up in the blood and seeps into the spaces between the body's cells.
Causes of overhydration
The most common cause of overhydration is drinking too much pure water during strenuous exercise or work, to replace fluids lost due to sweating. This is quite common in the following circumstances:
Why does strenuous exercise trigger water toxemia?
The hypothalamus -located deep inside our brain- produces a hormone called vasopressin which regulates how the kidneys eliminate fluids. It is known as the antidiuretic hormone.
Preventing water intoxication
The best option is to keep a balance of input and output of fluids: you should try to drink as much as you are losing (if you are sweating 0.5 liters an hour drink 0.5 liters of fluid to replace the loss).
