Do kidney patients need to limit their intake?

Water intake management for kidney patients is a very important part of the treatment process. The kidney is an important organ for regulating the water and electrolyte balance in the body, and when the kidney function is impaired, the patient may need to limit the ingestion of water.I. Renal and water regulationThe kidneys remove the waste and excess water from the body by filtering the blood, while retaining the moisture and electrolyte required for the body. When the kidney function is reduced, the renal filtration function is impaired, which may cause moisture and electrolyte to remain in the body, causing complications such as edema, hypertension and even heart failure.Which kidney patients need to limit their water intakeThe kidney function is incomplete: when the kidney function is incomplete, the kidney cannot effectively exclude the excess moisture and therefore the intake of water needs to be limited.Decreased urine: If the patient’s urine is significantly reduced, such as less than 500 ml per day, water intake may need to be restricted.Eedema: Eedema is a form of water retention, and limiting water intake helps to reduce oedema.High blood pressure: Excessive moisture may lead to increased blood pressure, and high blood pressure patients need to control water intake.Patients of dialysis: The dialysis treatment removes water from the body, but control of water intake is required between dialysiss to avoid overweight growth.III. How to limit water intakeMonitoring of urine: Record daily urine and adjust water intake to the amount of urine.Control of liquid foods: Attention is paid to the moisture content of foods, such as those with high water content such as fruits and vegetables.Avoid high salt foods: high salt foods cause thirst and increase water intake.Use of weighers: periodic weighing, monitoring of body weight changes, and rapid weight gain may be a sign of overwatering.(c) Establish a drinking water programme: On the recommendation of a doctor, establish a daily intake of water and comply with it.IV. Attention to water intake restrictionsIndividual differences: The specific circumstances of each kidney patient vary, and the restrictions on water intake should be adjusted to the doctor ‘ s recommendations and the patient ‘ s specific circumstances.Avoid dehydration: Excessive restrictions on water intake can lead to dehydration, which is also detrimental to health.Nutritional balance: water limitation should be accompanied by adequate nutritional intake to avoid malnutrition.Monitoring electrolyte: Limiting water intake may affect electrolyte balance, requiring periodic check of electrolyte levels.Water management in exceptional circumstancesDiseases such as fever, diarrhoea: In cases of fever, diarrhoea, etc., the body may lose more moisture and may need to increase water intake appropriately.Summer or high-temperature environment: In summer or high-temperature environment, the body loses more moisture through sweat and should be properly replenished.ConclusionsRenal patients need to limit their water intake depending on their kidney function, urine, oedema, blood pressure levels and dialysis treatment. Under the guidance of a doctor, rational management of water intake is an important measure for maintaining the health of patients with kidneys. Proper water intake not only helps to reduce the kidney burden but also prevents complications. Accordingly, kidney patients should follow closely their own changes in urine and weight, follow the doctor ‘ s advice and develop their own water intake plan to ensure a balanced body so as to maintain a good quality of life.
