Background/Aims In today’s age, celiac disease (CD) is no longer solely characterized by chronic diarrhea in a malnourished child. Obesity is gradually being acknowledged as part of CD’s clinical course. Both conditions have been linked to alterations of gut microbiome. Given the difficulty of strict gluten-free diet adherence, there is a need for less restrictive adjunctive therapies. We aimed to investigate the prevalence of obesity in patients diagnosed with CD with the goal of developing new therapeutic approaches.
Methods Baseline data from the National Institute of Health’s All of Us Research Program, was used to evaluate the relationship between CD and obesity. A retrospective cohort study was conducted where groups of individuals with CD and without CD were matched by age range and health surveys. Statistical analysis with odds ratios (OR) with 95% confidence intervals (CI) were reported.
Results The prevalence of obesity was 32.6% in the CD group compared to 18.4% in the control group (OR, 2.111; 95% CI, 1.914–2.328; P< 0.0001). Women accounted for a greater population of patients with CD and obesity. The largest percentage of patients with CD and obesity were older than 65 years. The highest percentage of individuals in both the experimental and control groups were white, followed by African Americans.
Conclusions Our data shows a significant association between CD and increased prevalence of obesity. These results warrant further investigation into microbial changes and dietary exposures that affect the pathogenesis of both diseases.
The gut is an immune-microbiome-epithelial complex. Gut microbiome-host interactions have widespread biological implications, and the role of this complex system extends beyond the digestion of food and nutrient absorption. Dietary nutrients can affect this complex and play a key role in determining gut homeostasis to maintain host health. In this article, we review various dietary nutrients and their contribution to the pathogenesis and treatment of various intestinal diseases including inflammatory bowel disease, irritable bowel syndrome, colorectal cancer, and diverticulitis, among other such disorders. A better understanding of diet-host-gut microbiome interactions is essential to provide beneficial nutrients for gut health and to limit nutritional hazards to ensure successful nutritional management of gastrointestinal conditions in clinical practice.
