The Relationship Between Loneliness, Social Isolation, and Inflammatory Bowel Disease: A Narrative Review.

ABSTRACT

BACKGROUND: There is clear evidence that loneliness and social isolation have profound health consequences. Documenting the associations of loneliness and social isolation with inflammatory bowel disease (IBD) symptoms, disease severity, and treatment outcomes could meaningfully improve health and quality of life in patients with IBD. PURPOSE: The purpose of this narrative review was to synthesize the empirical evidence on the associations of loneliness and social isolation with IBD symptoms, disease severity, and treatment outcomes. METHODS: Articles were identified through systematic database searches. Quantitative studies that enrolled patients with IBD were included if they examined one of the following outcomes: (a) loneliness or social isolation or (b) IBD-related symptoms, disease severity, or treatment outcomes. RESULTS: We identified 1,816 articles after removing duplicates. Of the 18 studies that met the inclusion criteria, 15 were cross-sectional and 3 were longitudinal. Overall, studies found that loneliness was associated with greater disease activity, functional gastrointestinal symptoms, IBD illness stigma, depressive symptoms, daily IBD symptom burden, reduced resilience, and poorer quality of life. Social isolation was associated with higher prevalence of IBD hospitalizations, premature mortality, and depression. CONCLUSIONS: Findings suggest that loneliness and social isolation are associated with poorer health and quality of life in patients with IBD. Prospective cohort studies examining the biobehavioral mechanisms accounting for the associations of loneliness and social isolation with IBD-related outcomes are needed to guide the development of psychological interventions for individuals living with IBD.

This article explores the connection between loneliness, social isolation, and health outcomes in people with inflammatory bowel disease (IBD). While loneliness and social isolation are known to negatively impact health in other chronic diseases, their specific effects within IBD have been far less studied. This study conducted a narrative review and found that loneliness is linked to more severe IBD symptoms, including increased disease activity, greater gastrointestinal distress, and lower quality of life. Similarly, social isolation is associated with higher rates of IBD-related hospitalizations, depression, and reduced coping abilities. These findings highlight the importance of addressing loneliness and social isolation in patients with IBD. Doing so may be key to developing psychological interventions that improve the well-being and health of those living with IBD.
