Abstract:
The most important goal in the treatment of patients with diabetes is to lower the risk of long-term diabetes complications. Hyperglycaemia is the most important risk factor for microvascular complications in diabetes, but, in addition to hyperglycaemia, several other risk factors, particularly dyslipidaemia, elevated blood pressure and smoking, also determine the risk of macrovascular complications. In this review, we present evidence from longitudinal population-based studies that hyperglycaemia is an important risk factor for long-term complications of diabetes and discuss the results from clinical trials of the effects of the treatment of hyperglycaemia on the prevention of long-term micro- and macrovascular complications in type 1 and type 2 diabetes. An HbA(1c) target of <7.0% for the treatment of diabetes is generally accepted on the basis of evidence from several trials, whereas a target of <6.5% may be reasonable for patients with a short duration of type 2 diabetes and without extensive atherosclerosis.
Insights
Lowering blood glucose levels is key to preventing long-term diabetes complications. Effective diabetes management, including controlling hyperglycemia (high blood sugar), reduces risks for both microvascular and macrovascular issues.
Area of Science:
- Endocrinology
- Metabolic Diseases
- Clinical Medicine
Background:
- Diabetes mellitus management aims to mitigate long-term complications.
- Hyperglycemia is a primary risk factor for microvascular complications.
- Dyslipidemia, hypertension, and smoking contribute to macrovascular risks.
Purpose of the Study:
- To review evidence linking hyperglycemia to long-term diabetes complications.
- To discuss clinical trial outcomes on hyperglycemia treatment for complication prevention.
- To evaluate target HbA1c levels for type 1 and type 2 diabetes.
Main Methods:
- Review of longitudinal population-based studies.
- Analysis of clinical trial data on hyperglycemia treatment.
- Synthesis of evidence regarding micro- and macrovascular complication risks.
Main Results:
- Hyperglycemia is a significant risk factor for long-term diabetes complications.
- Treatment of hyperglycemia impacts the prevention of micro- and macrovascular complications.
- An HbA1c target of <7.0% is widely accepted; <6.5% may suit select type 2 diabetes patients.
Conclusions:
- Effective glycemic control is crucial for diabetes patient outcomes.
- Individualized HbA1c targets should consider disease duration and comorbidities.
- Managing hyperglycemia and other risk factors is essential for comprehensive diabetes care.
