Generally, patients with kidney disease can drink a normal amount of water. However, in some cases, the doctor may instruct you to drink less or more water!
So what about drinking less? When to drink more? Let's take a look
When to drink less water
1/Edema: When edema occurs in situations such as nephrotic syndrome and acute nephritis syndrome, it is necessary to limit water intake in order to avoid aggravating body edema, elevated blood pressure, or even pulmonary edema. Generally, when limiting water intake, the amount of fluid consumed in a day is: urine plus 500ml. This 500ml is to supplement the invisible water loss of our body, such as the water brought out by respiration and evaporation.
2/Oligouria or anuria: Acute renal failure, chronic renal failure, and other conditions can lead to oliguria or anuria. Water intake is limited based on weight gain, blood pressure levels, and water excretion.
3/Dialysis patients: Although regular dialysis can help us eliminate excess water, dialysis patients must follow the doctor's instructions and limit fluid intake, which can ensure that the weight gain in the dialysis room is within the allowable range, generally not exceeding 5% of the standard body weight, thereby ensuring the dialysis effect.
When should I drink more water
1/When catching a cold, especially with fever, diarrhea, dehydration, and other conditions: At this time, insufficient water supply can lead to insufficient blood volume, leading to insufficient renal perfusion, and it is necessary to drink more water.
2/High uric acid: High uric acid can easily form urinary stones, and it is necessary to drink more water to help the body excrete.
3/Visual hematuria attack: When visual hematuria occurs, there are many red blood cells. To avoid red blood cells blocking the renal tubules, we need to drink more water and alkalize urine at the same time.
4. Angiographic examination: Patients with kidney disease need to be fully hydrated before and after the contrast agent. Not only should they drink more water, but sometimes the doctor will also ask the patient to receive intravenous fluids.
5/Have urinary stones: Some urinary stones can be excreted through urine and require drinking more water.
6/Sweating too much: This is the same as diarrhea and fever. The body loses too much water and does not replenish enough blood capacity.
