Can drinking to much water be lethal?

Yes, drinking too much water can be lethal. This condition is called water intoxication or hyponatremia, and it occurs when the body's sodium levels become too diluted. Sodium is an electrolyte that helps regulate the balance of fluids in the body, and when its levels are too low, the cells in the body start to swell. This can lead to a number of problems, including:

* Headache

* Nausea

* Vomiting

* Diarrhea

* Confusion

* Seizures

* Coma

* Death

Water intoxication is most common in people who drink large amounts of water in a short period of time, such as during an endurance race or after intense exercise. It can also occur in people who have certain medical conditions, such as kidney disease or heart failure.

If you think someone is experiencing water intoxication, it is important to seek medical attention immediately. Treatment typically involves giving the person fluids containing electrolytes, such as saline solution.
