From the Guidelines
The patient's current insulin regimen should be optimized, and a comprehensive diabetes management plan should be implemented to address the severely elevated blood glucose level of 475 mg/dL and prevent life-threatening complications. Given the patient's severely elevated blood glucose level and continued dietary non-compliance, it is essential to take a multifaceted approach to manage their diabetes.
- The administration of 14 units of lispro (rapid-acting insulin) and 10 units of glargine (long-acting insulin) was an appropriate initial treatment, but the patient's continued high-carbohydrate intake requires additional interventions.
- Requesting an endocrinology consultation to optimize the insulin regimen is crucial, as the patient may benefit from adjusting their basal insulin dose, implementing a sliding scale insulin protocol based on pre-meal glucose readings, or adding non-insulin agents such as metformin, as suggested by the 2023 standards of care in diabetes 1.
- The patient needs diabetes education focusing on carbohydrate counting, portion control, and understanding how food choices directly impact blood glucose levels, as emphasized in the 2025 standards of care in diabetes 1.
- Monitoring blood glucose every 2-4 hours until stabilized below 200 mg/dL and checking for ketones if glucose remains above 300 mg/dL is essential to prevent diabetic ketoacidosis or hyperosmolar hyperglycemic state, as recommended by the 2021 management of diabetes and hyperglycaemia in the hospital guidelines 1.
- Assessing for signs of hyperglycemic crisis, including polyuria, polydipsia, and altered mental status, is critical to ensure prompt intervention and prevent life-threatening complications.
- Considering the patient's current insulin regimen, it may be necessary to adjust the glargine dose based on fasting fingerstick glucose test results, as suggested by the 2024 standards of care in diabetes 1, to achieve a fasting goal of 90-150 mg/dL.

From the Research
Patient's Condition and Treatment
- The patient's sugar level is 475, and they have been administered 14u of lispro and 10u of glargine.
- The patient is fine with normal vitals but continues to eat excessively despite being advised against it.
- The patient's noncompliance with dietary advice may be contributing to their high sugar levels.
Insulin Management
- Studies have shown that insulin lispro mixture can provide better glycemic control than insulin glargine alone in patients with type 2 diabetes 2, 3, 4.
- However, the optimal insulin regimen for this patient is unclear, and more information is needed to determine the best course of treatment.
- The use of insulin lispro protamine suspension versus insulin glargine has been compared in several studies, with mixed results 5.
Glycemic Control
- The patient's high sugar level (475) indicates poor glycemic control, which can be managed with adjustments to their insulin regimen and dietary advice.
- Studies have shown that combining insulin therapy with oral antihyperglycemic medications can improve glycemic control in patients with type 2 diabetes 2, 5, 4.
- The patient's continued eating despite high sugar levels may be contributing to their poor glycemic control, and addressing this issue is crucial to improving their condition.
Future Directions
- Further research is needed to determine the optimal insulin regimen for patients with type 2 diabetes and high sugar levels.
- Studies should investigate the effects of different insulin regimens on glycemic control, hypoglycemia, and other relevant outcomes in patients with type 2 diabetes 6, 2, 3, 5, 4.
