How much water is too much?
Several factors can affect how well a person can remove (remove) excess water from their body to prevent hyponatremia / water intoxication. For example, as mentioned above, constant stress and / or health problems affect the kidneys and nervous system, which can increase the likelihood of water toxicity symptoms. healthnutritionhints
So how much water can you drink in a short period of
time?
If someone has normal / healthy kidneys, they should excrete
800 milliliters to 1 liter of fluid every hour. That's about 3.3 to 4.2 cups,
0.21 to 0.26 gallons, or about 0.84 to 1.04 quarts per hour.
Drinking more alcohol will cause electrolyte imbalances and
possibly some of the early symptoms associated with hyponatremia. Also remember
that if someone is exercising intensely (such as running a marathon,
exercising, or playing sports) by drinking a lot of water, they will retain
even more water because their body is experiencing a stress response.
Water poisoning is unlikely unless someone drinks a large
amount of water in a short amount of time (an hour or two). Water poisoning can
be avoided as long as a person's water intake does not exceed the amount lost
in urine or sweat.
In a case study, water intoxication caused the death of a
64-year-old woman due to severe hyponatremia. A few hours before going to bed,
she drank 30 to 40 glasses of water. Due to delirium, she drank more and more
water, although she vomited and felt unwell. (6)
In 2014, the Daily Mail reported that a 17-year-old high
school soccer player died of water poisoning after drinking four liters of
liquid to stop seizures during training. (7)
A 2002 investigation of several military water poisoning
cases and three deaths due to overhydration and cerebral edema found that all
cases were associated with the consumption of more than five liters (usually
10-20 liters) of water during the period. few hours. (8)
In 2007, Scientific America magazine published an article
that mentioned a 28-year-old woman who died after participating in a drinking
water competition in which she drank about six liters of water in three hours.
(9) The same article points to a 2005 study published in the
New England Journal of Medicine that stated that "one in six marathon
runners develop hyponatremia, or blood thinning caused by drinking too much
water."
Treatment of hyponatremia and water intoxication comes down
to regulating the level of fluid in the body, in particular, increasing the
level of sodium. Salt and water intake and excretion must be balanced. Keep in
mind that while sodium / salt may have gotten a bad reputation - mainly because
it is found in higher concentrations in processed foods - sodium is actually an
essential nutrient. For example, some of the functions of sodium include:
Helps control the quantity of water in and around cells.
Blood volume control.
Regulates blood pressure.
Allows your muscles and nerves to function properly.
When this happens,
treatment for water poisoning includes:
Gastric lavage or pumping / gastric lavage.
Sodium correction therapy.
Use of intravenous electrolytes.
Diuretics to urinate more frequently and increase blood
volume.
Vasopressin receptor antagonists.
