The ammonia odor in the wheezing of dialysis patients is mainly caused by the accumulation of urea in metabolites in the body. Dialysis patients with renal failure, metabolite excretion obstacles, resulting in metabolite accumulation in the body. However, part of the metabolites will be excreted through respiration, and there is a component of urea in the metabolites, so there is an ammonia odor in the wheezing of dialysis patients. The kidney function fails, and the excess water and toxins in the body cannot be excreted, so dialysis is needed to maintain life, excrete the excess water and toxins out of the body, and alleviate the related symptoms. If dialysis patients experience any discomfort, it is recommended that they go to a regular hospital in time and receive standardized treatment under the guidance of a doctor.
