Patients with elevated blood ammonia should pay attention to avoid eating too much protein in their diet. Plant protein is the main protein at this time, avoiding the intake of animal protein, while plant protein can be chosen from soy products. In addition, you can also eat more fruits and vegetables to keep your bowels open. When there is a significant increase in blood ammonia, it can cause central nervous system dysfunction and even coma, leading to death. When blood ammonia is significantly elevated, food alone is not able to lower blood ammonia, but should be treated with medication in a timely manner. Drugs to lower blood ammonia are usually administered through intravenous infusion, such as branched-chain amino acids, ornithine menthylate, arginine hydrochloride, sodium benzoate, sodium phenylacetate, etc. Of course, oral administration of lactulose and neomycin, which can reduce ammonia production by intestinal bacteria, can also play a very important role in reducing blood ammonia.
