As a result, "water poisoning" was sent to the ICU...
Women drink 3 liters of water for 2 hours
Nearly killed in the ICU
Ms. Liu of Zhengzhou, Henan Province, needed to drink a lot of water and laxative drugs because of the colonoscopy, but after drinking the medicine, she never had the idea of going to the toilet. Ms. Liu thought that she might have drunk less water, so she drank 3 liters of water in 2 hours. But after a while, there were symptoms of nausea, vomiting, cramps in the hands and feet, and confusion, and the family rushed to the hospital for treatment.
The doctor found that Ms. Liu suffered from "dilutive hyponatremia", commonly known as "water poisoning", and immediately sent Ms. Liu to the ICU. After rescue, Ms. Liu was finally freed from the danger of life.
Chen Xiaotian, deputy director of the Department of Clinical Nutrition of Nanjing Drum Tower Hospital, explained: "Ms. Liu drank a lot of water at one time, and the water itself did not have osmotic pressure, and after it entered the body, it diluted our blood at once, so that the osmotic pressure of the blood dropped very low. Intracellular fluid and extracellular fluid actually have a balance, at this time the intracellular fluid will absorb a large amount of water, the extracellular fluid water into the cell. The key is this part of the brain, after a lot of water is inserted in the cells at once, cerebral edema appears. If the brain is edema, there will be problems with intracranial hypertension, so there will be nausea, vomiting, and even convulsions, and severe cases will lead to coma. ”
According to the doctor, we will drink water every day, and we will also drain water through sweating, urine and other ways, but if a large amount of water is ingested in a short period of time and is not discharged, these waters accumulate in the body, which will lead to edema, lung edema, brain edema, and even death.
In general, symptoms are relieved when patients with "water poisoning" stop their water intake. But if the treatment is not timely, it will cause permanent damage to the nervous system and even endanger life.
Patients with poor renal and cardiac function
Control the amount of water you drink as directed by your doctor
So how much water is more appropriate to drink per day?
Chen Xiaotian, deputy director of the Department of Clinical Nutrition at Nanjing Drum Tower Hospital, said: "The 2016 and recently published 2022 edition of the Dietary Guidelines for Chinese Residents has a clear recommendation for water intake, between 1500 ml and 1700 ml per day. It also clearly proposes to drink enough water, while it is necessary to drink a small amount of water many times, and not to drink too much at one time. For the recommendation of drinking water, it is recommended to drink white water or light tea, it is recommended not to drink or drink less sugary drinks, do not use drinks to replace water. ”

Doctors recommend taking the initiative to drink water, do not feel thirsty and then drink water, for example, before or during exercise can be appropriately replenished.
In addition, patients with poor renal function and heart function should pay attention to controlling the amount of water they drink. "People with poor kidney function generally monitor their urine output and control their water intake according to the amount of urine they excrete. Patients with kidney failure should be dialysis, and the amount of water consumed is strictly controlled every day, otherwise it will lead to the aggravation of uremia; patients with poor heart function should also limit drinking water, because it will increase the burden on the heart. Chen Xiaotian said.
