Impact of probiotics on health-related quality of life in Type II diabetes mellitus: A randomized single-blind, placebo-controlled study

Abstract

Objective: The objective of this study is to analyze the impact of probiotics on health-related quality of life (HRQOL) of type 2 diabetes mellitus (T2DM) patients. Materials and Methods: This was a prospective, interventional single-blind, randomized study; a total of 80 T2DM patients were randomized as single blinded into two groups: interventional group consuming pre and probiotic capsules and control group consuming placebo capsules capsules; the study was conducted for a duration of 3 months, and the readings were recorded at 0, 6, and 12 weeks from all participants for the analysis of HRQOL. Results: Seventy-five participants out of 80 completed the study. Glucose markers such as fasting blood sugar (P = 0.42), postprandial blood sugar (P = 0.60), homeostatic model assessment-insulin resistance (P = 0.20), and serum insulin (P = 0.22) had shown beneficial effect on HRQOL of the T2DM patients. The influence of gender on HRQOL was not noteworthy (P = 0.68), whereas age had shown significant influence on HRQOL of the patients (P = 0.02) with the use of probiotics. Conclusion: The results of study had shown important improvement in HRQOL of the T2DM patients with the use of probiotics in the interventional group compared to the control group.
