2 negative nitrogen balance negative nitrogen balance can cause weight loss, patients with cachexia and hypoalbuminemia. Hypoalbuminemia is one of the important causes of renal edema. Factors that cause negative nitrogen balance:
The patient intake of protein restricted or because of anorexia, nausea and vomiting caused by reduced protein intake;
Some substances such as methyl guanidine can enhance the catabolism of tissue proteins;The combination of infection can lead to protein degradation;The result of protein loss due to hemorrhage;With the loss of a certain amount of urinary protein.A large number of urea from the blood into the intestinal cavity. Enteric bacteria can break down the urea and release ammonia, ammonia transported to the liver by the blood, the urea can be synthesized, but also the
synthesis of non essential amino acids, which is beneficial to the body. Therefore, some people believe that the intake of protein in patients with uremia can be lower than normal, even less than 20g per day to maintain nitrogen balance, but must be given a higher nutritional value of protein.
