Intensive glycemic control (targeting HbA1c <6.0-6.5%) slows the progression of microvascular complications (retinopathy, nephropathy, neuropathy) in type 2 diabetes, but does not significantly reduce macrovascular events within the first 3-5 years of treatment.
For Type 2 Diabetes, keeping blood sugar very low (HbA1c <6.5%) protects your eyes, kidneys, and nerves, but this protection takes years to show up in heart health. Be aware that aggressive sugar lowering can increase the risk of dangerous low blood sugar episodes, so the target must be balanced carefully with your doctor.
StrongQualifiesHIGH confidence
Landmark clinical trials have demonstrated that intensive glycemic control slows progression of microvascular complications (retinopathy, nephropathy, and neuropathy)... Long-term follow-up has demonstrated that intensive glycemic control also decreases risk of macrovascular disease, albeit rigorous evidence of macrovascular benefit did not emerge for over a decade.
Why this rating
Based on landmark randomized controlled trials (DCCT, UKPDS, ACCORD, ADVANCE).

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
