Impact of dietary beliefs and practices on patients with inflammatory bowel disease: An observational study from India

Abstract

Background and Aim

Patients with inflammatory bowel disease (IBD) are at a risk of nutritional deficits because of poor dietary beliefs and practices. There are no data on this aspect from Asia, which is experiencing a rise in IBD incidence. We aimed to establish dietary beliefs and practices in patients of IBD from India.

Methods

Patients with ulcerative colitis (UC) and Crohn's disease (CD) followed up between November 2016 and March 2017 were included. A questionnaire extracted information on the patients' sociodemographic, nutritional and disease profile, smoking and drinking habits, dietary beliefs and practices, current dietary preferences, intake and avoidance, dietary changes made after diagnosis of IBD, dietary changes made during relapse, frequency of consumption of major food groups, and the attitudes toward dietary advice.

Results

A total of 316 patients (218 UC and 98 CD; mean age: 38.5 ± 12.2 years) were included. Forty‐four percent patients perceived food as a risk factor for IBD, 52% felt dietary habits to have a more important role than medicines in disease control, 77% reported certain foods improve symptoms during relapse, 86% had modified their diet since the diagnosis of IBD (UC > CD, P = 0.04), 90% imposed food restrictions, and <50% had received dietary counseling. About 40% of patients could not meet their dietary requirements and 66% had decreased their dietary intake since diagnosis, which further decreased during relapse (85%).

Conclusion

Dietary beliefs and practices play a central role in perception of disease in IBD patients. A large majority of them make dietary changes which can lead to undernutrition. Proper dietary counseling is required in these patients to prevent malnutrition.
