Drinking 3.2L of water caused poisoning. What was the main cause of the accident?

As the saying goes, water is the source of life, and all living things are inseparable from water. But recently, a woman in Shenzhen drank 3.2 liters of water at one time to hold in her urine for a B-ultrasound. She then developed nausea and vomiting, even twitching of limbs and coma. Through examination, it was found that he was intoxicated due to drinking too much boiled water at one time. It took more than 4 hours of rescue to escape the danger of life. Many people wonder why drinking water can cause poisoning and endanger life?

In fact, water intoxication is a medical diagnosis called dehydration and hyponatremia, and it is not poisoning caused by drinking water. This is due to the drainage organs of our body, namely the kidneys. The ability and workload of our kidneys to secrete urine is limited. If we drink a large amount of boiled water in a short period of time and exceed the drainage capacity of the kidneys, it will not only increase the burden on the kidneys, but the remaining water will be stored in our bodies. , affecting the entire electrolyte balance in our body, causing an increase in blood volume, lowering the osmotic pressure of the blood, and increasing blood circulation volume; when the blood flows through the brain, a large amount of water will penetrate into the brain parenchyma through the blood circulation, It can range from convulsions all over the body to coma in severe cases. In more serious cases, it can cause cerebral edema. If the rescue is not timely, it may even lead to death. This is why water intoxication occurs after drinking too much water in a short period of time. Therefore, when replenishing water, we must remember not to drink a large amount of boiled water or purified water in a short period of time, but to drink small amounts many times; especially after exercise or when there is a slight heatstroke due to hot weather, replenishing water first Choose saline or electrolyte drinks to avoid water intoxication.

In life, many people think that as long as it is good for the body, eating more will be enough. In fact, this idea is wrong. As the saying goes, too much is not enough. Excessive intake of anything may lead to poisoning. For example, excessive oxygen inhalation can cause poisoning, and excessive intake of vitamins can also cause poisoning. Therefore, the amount must be moderate.
