Modern medical guidelines emphasize that HbA1c targets should be personalized for each patient rather than applying a universal standard (< 7%).
​Target < 7%: Ideal for younger patients, recently diagnosed cases, and those without recurrent hypoglycemia or severe chronic conditions.
​Target 7% – 8%: Preferred for older adults, patients with advanced heart or kidney disease, or those with a history of severe hypoglycemia.
​The goal is achieving optimal glycemic control safely. Aggressive reduction of HbA1c in certain groups can lead to severe hypoglycemia and serious complications.
