Fatigue in IBD: epidemiology, pathophysiology and management

Area of Science:

• Gastroenterology and Immunology
• Clinical Medicine
• Microbiome Research

Background:

• Fatigue affects a high percentage of Inflammatory Bowel Disease (IBD) patients, impacting quality of life and societal costs.
• The etiology and pathophysiology of IBD-related fatigue remain poorly understood, hindering effective treatment.
• Existing treatments for IBD fatigue are limited, necessitating further research into underlying mechanisms.

Purpose of the Study:

• To review current theories on the development of fatigue in IBD.
• To explore contributing factors such as nutritional status, inflammation, metabolism, and the gut microbiome.
• To discuss potential therapeutic interventions and propose a management strategy for IBD-related fatigue.

Main Methods:

• Literature review of existing theories and research on IBD fatigue.
• Analysis of contributing factors including nutritional deficiencies, inflammation, and metabolic alterations.
• Exploration of the gut-brain axis and the role of the gut microbiome in fatigue.

Main Results:

• Fatigue is prevalent in both active and remissive IBD, significantly reducing quality of life.
• Key contributing factors include inflammation, nutritional deficits, altered metabolism, and gut microbiome dysbiosis.
• Nutrient repletion, psychological, and pharmacological interventions show potential for fatigue management.

Conclusions:

• Effective management of IBD fatigue requires addressing multifactorial causes including inflammation, nutrition, and the gut microbiome.
• Further research into the mechanisms of fatigue and clinical trials for novel interventions are essential.
• A comprehensive therapeutic strategy integrating various approaches is needed for IBD patients suffering from fatigue.
