Full definition
HbA1c (glycated haemoglobin) reflects average blood glucose over approximately three months, expressed as a percentage or mmol/mol.

RSSDI typically targets HbA1c below 7–7.5% for most adults. GLP-1 RAs are added when HbA1c remains above target despite metformin and lifestyle. Monitored every 3–6 months on therapy. In India, these concepts appear in RSSDI and ICMR guidance for type 2 diabetes and obesity care—always confirm details with your prescribing physician.
