Abstract
Type 2 diabetes mellitus (T2DM) is highly prevalent among the geriatric population
in India, driven by aging-related metabolic changes and lifestyle factors. The gut–
glycemic axis has emerged as a key regulator linking intestinal microbiota with
glucose metabolism. Dysbiosis contributes to insulin resistance, inflammation, and
poor glycemic control in T2DM. Metformin, the first-line therapy, exerts part of
its effects through modulation of gut microbiota. Prebiotics and probiotics have
shown potential in improving metabolic outcomes by enhancing beneficial bacteria
and short-chain fatty acid production. Their use alongside metformin may provide
synergistic benefits and improve treatment tolerance. However, evidence in the
Indian elderly population remains limited despite distinct dietary and microbiome
patterns. Understanding these interactions may enable development of targeted,
microbiome-based strategies for better diabetes management.
