Micronutrient deficiencies in inflammatory bowel disease.

Area of Science:

• Gastroenterology
• Clinical Nutrition
• Immunology

Background:

• Inflammatory bowel disease (IBD) encompasses Crohn's disease and ulcerative colitis.
• Malnutrition, including protein-energy and micronutrient deficiencies, is a common complication of IBD.
• These deficiencies contribute to disease morbidity and can exacerbate inflammatory processes.

Purpose of the Study:

• To review recent advances and evidence-based knowledge on micronutrient status in IBD patients.
• To summarize the significance, epidemiology, and treatment of micronutrient deficiencies in IBD.
• To provide recommendations for managing these deficiencies.

Main Methods:

• Literature review of recent studies on micronutrients and IBD.
• Analysis of epidemiological data on micronutrient deficiencies in IBD.
• Synthesis of current treatment options and clinical recommendations.

Main Results:

• Over 50% of IBD patients exhibit micronutrient deficiencies, most commonly iron, B12, D, K, folic acid, selenium, zinc, B6, and B1.
• Deficiencies are more frequent in Crohn's disease than ulcerative colitis and during active disease phases.
• Micronutrient deficiencies correlate with a more complicated disease course, with iron deficiency being a primary cause of anemia.

Conclusions:

• Micronutrient deficiencies are common and clinically significant in IBD.
• A high index of suspicion for these deficiencies is warranted in IBD patients.
• Timely treatment can prevent irreversible sequelae and reduce morbidity.
