The new crown pneumonia epidemic is spreading. Experts recommend that you drink more water after the infection. You should also add water after the vaccine, but how should you drink water? Recently, many middle-aged and elderly people have been received in the emergency department. They were sent to the doctor due to dizziness and nausea due to low blood sodium caused by drinking a lot of water.
The Emergency Medicine Department of Xinguang Hospital has recently encountered some middle-aged and elderly people who were admitted to the emergency department due to hyponatremia. Many of them were caused by drinking a lot of water because they heard that they needed to “drink more water” after contracting the new crown or getting vaccinated. In fact, if the elderly do not exercise much and do not sweat excessively, it is good to drink water in moderation after vaccination or COVID-19. More importantly, rest more, get enough sleep, and do not stay up late. Excessive water intake can easily lead to hyponatremia. Severe convulsions and coma.
The daily water intake should not exceed 3000 CC, and a maximum of 500 CC should be added for vaccination
Fang Yuwei, director of the Department of Nephrology at Xinguang Hospital, said that drinking too much water will cause electrolyte imbalances in the body. For men weighing 60 kg, the upper limit of daily water intake is 2500-3000 CC, and women should be calculated at a 20% discount, not exceeding 2500 CC. When the body is inflamed and has a fever, such as vaccination or infection, the metabolism will be improved, the insensitivity of water loss will also increase, and the body’s demand for water will also increase. At this time, you can add a little more water, but it is recommended not to exceed 500 CC .
Fang Yuwei said that under normal circumstances, if you drink more than 3000 to 4000C.C. of water a day, excessive water will cause water poisoning, because the kidneys cannot handle so much water, and the water will dilute the sodium ions in the blood, and sodium ions are critical. The osmotic pressure balance between brain cells and body fluids, once this balance is broken, there will be hyponatremia, cerebral edema, severe fear of coma, epilepsy, and even sudden death in a short period of time.
Patients with chronic kidney disease should limit the amount of water and should not be encouraged to drink more water
If the change of sodium ions is not fast, the body can still adjust, but in the process, there will be hyponatremia, such as dizziness, nausea, etc. These are warning signs of too much water. As for the rate of change of sodium ions, in addition to the amount of water intake, it is also related to the function of the human kidneys. Fang Yuwei emphasized that patients with chronic renal dysfunction have poor renal function and low tolerance for changes in sodium ions. Therefore, these patients should not be encouraged to drink more water after the vaccine. Instead, it depends on the amount of urine to determine the water intake. Generally It is recommended to drink 1000-1500 CC a day. If the amount of urine is small, add 300 CC at most, and don’t drink until the feet are edema. In addition, soups, drinks, etc. in the diet should be included in the daily water calculation.
High-risk groups for primary polythirst water intoxication
Fang Yuwei said that drinking water intoxication is usually compulsive in clinical practice, because the human body will feel uncomfortable, and usually do not drink poisoning, but patients with primary polythirst have no sense of disease, they always feel thirsty and drink Water has become a high-risk group for water intoxication; some people even drink 5000C.C. of water and find chronic hyponatremia in blood draws, only to know that they are primary polythirst.
