Management of Severe Hyperglycemia in Type 2 Diabetes

Initial Assessment and Management

The American Diabetes Association recommends starting insulin therapy immediately, combined with lifestyle intervention, in patients with severe hyperglycemia (random blood glucose ≥300 mg/dL) and likely symptomatic presentation 1, 2, 3
Random blood glucose ≥300 mg/dL is an absolute indication for insulin therapy at diagnosis, as recommended by the American Diabetes Association 1, 2, 3
Patients with severe hyperglycemia and low body weight (e.g., 35 kg) may require nutritional rehabilitation and close monitoring for complications 1, 4

The American Diabetes Association recommends starting with basal insulin (e.g., NPH or glargine) at a dose of 0.25-0.5 units/kg/day, with the option to add prandial insulin (e.g., regular or rapid-acting) if necessary 5
The European Association for the Study of Diabetes recommends titrating insulin doses based on patterns over 3 days, with a goal of achieving target glucose levels 4, 5

The American Diabetes Association recommends starting metformin 500 mg once or twice daily with meals, and titrating up to 2000-2550 mg daily as tolerated 1, 4, 6, 3
Metformin should be initiated concurrently with insulin therapy, not delayed, as recommended by the American Diabetes Association 1, 2, 3

The American Heart Association recommends reducing refined carbohydrates and sugar intake, and emphasizing whole grains, vegetables, and lean proteins 1, 4
The American Diabetes Association recommends starting with 30 minutes of moderate aerobic activity 5 days per week, and adding muscle-strengthening activities 2-3 times weekly 1, 4, 2

The American Diabetes Association recommends checking HbA1c every 3 months, and adjusting treatment as needed to achieve target glucose levels 4, 6, 8
The European Association for the Study of Diabetes recommends monitoring for complications, such as ketonuria, and adjusting treatment accordingly 1, 4, 6
