Advancements in malnutrition in elderly inflammatory bowel disease patients

Abstract

Inflammatory bowel disease (IBD) comprises a collection of chronic, non-specific inflammatory disorders affecting the gastrointestinal tract, the exact causes of which remain undefined. Research has indicates that the elderly population accounts for 10%-20% of IBD cases, and the prevalence of IBD among the elderly is steadily increasing alongside the patient base. In comparison to their younger counterparts with IBD, genetic factors play a diminished role in the development of elderly IBD, whereas immune system dysregulation and disruptions in gut microbiota assume greater significance. Among the elderly, various other prevalent conditions frequently exhibit symptoms akin to IBD, thereby rendering diagnosis notably challenging. Given that both IBD and aging process independently constitute risk factors for malnutrition, the probability of concurrent malnutrition substantially escalates within this subgroup. However, the realm of research regarding malnutrition in elderly IBD patients remains constrained. This review delves comprehensively into the status of malnutrition among elderly IBD patients, encompassing aspects of screening, assessment, and dietary management.
