Management of Hypoglycemia in Non-Diabetic Dialysis Patients

Pathophysiology

• Decreased gluconeogenesis by the kidneys contributes to hypoglycemia in non-diabetic ESRD patients, with the kidneys normally contributing significantly to glucose production 1
• Impaired counterregulatory hormone responses to hypoglycemia occur in ESRD patients, leading to a blunted hormonal response 1
• Nutritional deprivation is common in dialysis patients and contributes to hypoglycemia, with patients often having specific dietary requirements 1

Nutritional Support

• Providing carbohydrate-rich snacks during dialysis can help prevent hypoglycemia, particularly in patients with pre-dialysis glucose levels ≤100 mg/dL, reducing hypoglycemia recurrence from 46.5% to 15% in subsequent dialysis sessions 2

Diagnostic Evaluation

• Malnutrition should be assessed carefully in non-diabetic ESRD patients with recurrent hypoglycemia, as it is both a cause and consequence of the condition, according to the American Journal of Kidney Diseases 3

Monitoring Approach

• Continuous glucose monitoring (CGM) is superior to point-of-care testing for detecting asymptomatic hypoglycemia in non-diabetic dialysis patients, allowing for more accurate monitoring of glucose levels 1
• Maintaining fasting blood glucose levels of 110-130 mg/dL minimizes hypoglycemia risk while avoiding complications in non-diabetic dialysis patients, as recommended by the American College of Physicians 1

Special Considerations

• Patients should be evaluated for weight changes carefully, as they may require adjustment of dry weight targets for dialysis, and malnutrition is both a cause and consequence of recurrent hypoglycemia in dialysis patients, according to the American Journal of Kidney Diseases 3
