Digestive and nutritional considerations in celiac disease: could supplementation help?

Area of Science:

• Gastroenterology and immunology
• Nutritional science

Background:

• Celiac disease involves heightened intestinal immune activation.
• This immune response can disrupt digestive and absorptive functions.
• Associated complications include pancreatic and lactase insufficiencies, dysbiosis, and nutrient deficiencies.

Purpose of the Study:

• To explore the impact of celiac disease on digestive and absorptive processes.
• To identify common nutritional deficiencies and health complications in celiac patients.
• To evaluate the potential benefits of nutritional supplementation beyond a gluten-free diet.

Main Methods:

• Review of existing research on celiac disease pathophysiology.
• Analysis of studies investigating nutritional status in celiac individuals.
• Examination of evidence for nutritional interventions.

Main Results:

• Increased immune activation in celiac disease compromises digestion and absorption.
• Patients are prone to deficiencies (folic acid, B12, iron, D), pancreatic insufficiency, dysbiosis, and bone loss.
• Nutritional supplementation shows promise in managing these complications.

Conclusions:

• Celiac disease leads to significant gastrointestinal and systemic complications.
• A gluten-free diet is primary, but nutritional support is crucial.
• Supplementation can aid in regulating deficiencies and mitigating bone loss.
