In fact, the answer to this question is not unique. Because for kidney friends at different stages, the role of drinking water may be completely different. For example, patients with early kidney disease, after nephritis, glomerulitis and other diseases appear, drinking more water will actually help the kidneys to discharge metabolic waste and garbage from the human body as soon as possible, which is also good for protecting the kidneys. Some patients need to drink plenty of water to promote drug metabolism and excretion, so as to avoid damage caused by kidney accumulation. From this perspective, drinking water is good for the kidneys.
However, drinking more water is actually a burden for kidney friends with renal insufficiency, renal failure or edema. People's water intake needs to be excreted through kidney metabolism, but the renal function has been damaged, and it is impossible to maintain normal urination and other functions. Drinking more water will only keep water in the human body, and may even lead to water poisoning.
Therefore, drinking more water is actually beneficial to the kidneys. It is enough for people with healthy renal function to achieve a daily water intake of 1500ml. But for patients with special kidney disease, drinking water should be cautious.
Wrong way 1: When thirsty, when drinking water.
For some people who are busy at work and have no habit of drinking water, they only think of drinking water when they feel thirsty. But at this time, the human body is already in a state of water shortage, and the kidneys can't get excess water in the filtered blood, so there is no way to form urine and bring out metabolic waste in the body. Such people often have problems such as less frequent urination, heavy urine smell and yellowing.
Mistake 2: I like to use tea and juice instead of water.
What's the taste of boiled water? Tea and juice are better. Supplementing water and nutrition. But you know what? These drinks want to replenish water for the human body, and they have to go through the metabolism of the stomach to send water to the kidneys. No matter how much you drink, you can't quench your thirst, and the hydration effect is not good.
Moreover, some fruit juices and drinks contain a lot of sugar, and excessive intake of free sugar may increase the risk of arterial stenosis, which is also unfavorable to renal blood vessels.
Wrong method 3: drink plenty of water at one time.
This kind of situation mostly happens after serious water shortage such as sauna and strenuous exercise. People need to drink a lot of water to replenish water. However, it may also lead to excessive water intake in a short period of time, so that the kidneys cannot handle so much water at one time, and the blood is suddenly diluted, which will have a greater burden on the heart and a heavier burden on the kidneys to filter blood.
Mistake 4: Drink water after meals to promote digestion.
Actually, drinking water for half an hour after a meal is not recommended. Not to mention that food itself has moisture, and it is not easy to lack water in a short time. From the point of view of digestion, drinking water within half an hour after a meal is likely to dilute gastric acid, which is not good for digestion and absorption of food.
And eager to drink water after meals, does it also mean that the taste of diet is heavier? The dietary taste of heavy salt, sugar and heavy oil will also make the kidneys face a heavier metabolic burden, especially after a large amount of sodium ions are ingested, which will disturb the blood pressure in the human body and may also bring a lot of harm to the kidneys.
Check your daily drinking habits to see if there are four wrong ways. If so, it should be corrected as soon as possible to avoid damaging the kidneys.
The first step is timing.
It stands to reason that a part of water will be consumed every once in a while in the human body, and a certain amount of urine will be produced after kidney metabolism. People need to replenish water at this time. The whole day can be divided into multiple time periods, and water can be replenished regularly. This method is effective after getting up, before going to work, before lunch, after waking up from a nap, around 3 pm, around 6 pm, before dinner and before going to bed 1 hour.
The second step is to quantify.
The source of water supplement is not only boiled water, but also water in food, soup during meals and daily fruit intake. You can drink 150-200 ml warm water in the morning, and the total amount of water you drink should be adjusted in time. For example, after lunch, after waking up from a nap, you can choose to drink 200 ml of warm water, or eat some fruits properly, which can actually replenish water. Warm milk can be used instead of boiled water before going to bed, which is also a good choice for people with poor sleep.
Drinking plenty of water is not only a casual greeting to patients with kidney disease, but also the key to protecting kidneys. If you drink water in the wrong way, it may not be worth the loss, but it will hurt your kidneys.
