Drinking much or less fluid temporarily will cause no serious harms to our body. However, for dialysis patients, they must control their fluid intake strictly, as both excess fluid intake and less fluid intake will produce bad influence on their illness condition. However, how much water can a dialysis patient drink a day?
How much water to drink with kidney dialysis?
Kidneys play a crucial role for maintaining fluid balance in the body. When kidneys are affected badly, their ability to expel excess fluid will decrease, so exact fluid intake depends on special illness condition very much. Generally speaking, for dialysis patients, the more urine they discharge every day, the more fluid intake will be allowed. Urine output is not the only factor that help to decided how much water a dialysis patient can drink a day. Aside from it, dry body weight is also a factor that helps to decided the fluid intake for dialysis patients. Drinking too much water will cause increase of body weight. For dialysis patients, the increase of body weight between two dialysis is usually suggested to be the 3%-5% of the dry body weight and no more than 7%. For instance, for a dialysis patient with dry body weight 60kg, increase of body weight is no more than 4.2kg between two dialysis. Otherwise, low blood pressure and muscle cramp will be caused easily during dialysis.
Other limitations for dialysis patients aside from fluid intake
Fluid intake is just one of the aspects that dialysis patients need to pay attention to. In reality, aside from it, there are many factors that need to be paid extra attention by dialysis patients:
1. Adjust potassium intake, phosphorus intake and sodium intake. Although dialysis helps to discharge excess electrolyte, sometimes dialysis is insufficient and electrolyte imbalance still exist after dialysis. Exact potassium intake, sodium intake and phosphorus intake depends on exact illness condition.

2. Try to ingest more protein, as some protein are always filtered out during dialysis. Usually, 1.2grams of protein per pound of body weight a day is suggested.
Dialysis is a must for people with completely failed kidneys. It is helpful, but can cause lots of unnecessary problems. Therefore, having an overall understanding about dialysis in advance, including fluid intake for dialysis patients, is very necessary.
