[A critical review of the GLIM criteria].

-Disease-related malnutrition (DRM) is a frequent syndrome in clinical practice, in which the mutual relationship between disease and malnutrition is observed. It is a specific form of malnutrition with causes other than poverty and social problems that make it difficult food production and distribution. Inflammation, anorexia, changes in body composition or in energy and protein requirements contribute to the development of DRM. This is associated with an increase in morbidity, mortality and economic expenditure. There are numerous tools to identify patients at risk of malnutrition, but until now there was no general consensus on the diagnostic criteria for malnutrition. The GLIM criteria provide a diagnostic system that has been accepted by the main international scientific societies in the field of clinical nutrition. In this article we describe its development, its application in different populations of patients and its comparison with other criteria or different diagnostic tools that contribute to its validation. This makes it possible to point out the advantages and limitations that have been described so far with the use of the GLIM criteria.
