Nutritional Care Process in Hospitalized Patients with Obesity-Related Multimorbidity

Obesity-Related Multimorbidity (ORM) is understood as the group of secondary diseases caused by metabolic alterations that arise from obesity. Nowadays there is a growing incidence of people with ORM who seek health services. Since this condition substantially impacts nutritional status and therefore in the survival prognosis during the hospital stay, ORM represents a challenge for health professionals. This forces doctors to specify nutritional recommendations according to clinical characteristics in individuals with obesity and types of comorbidities. Therefore, the objective of this narrative review is to present the current evidence-based recommendations that support the hospital nutritional care process for individuals with ORM. It concludes that nutritional treatment is complex and gaps in the research regarding this population group still exist. Because there are no specific guidelines for nutritional screening tools, calculating total energy requirements (alternatives to indirect calorimetry), determining fluid, protein, and immunonutrient requirements, the use of parenteral nutrition in ORM with kidney, liver, and heart failure and sarcopenic obesity that should be addressed in the new literature. For now, the standard practice in these cases is to prioritize the problem to be treated according to the maximum clinical benefit. Despite this, it is established that the nutritional care process must be systematic to be clear and objective. This document is addressed to all healthcare professionals who make up the multidisciplinary nutritional support team.
