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.
