Carbohydrate Coverage Formula:
| From: | To: |
Carbohydrate coverage refers to the calculation of insulin dosage needed to cover the carbohydrates consumed in a meal. It helps individuals with diabetes maintain stable blood glucose levels after eating.
The calculator uses the carbohydrate coverage formula:
Where:
Explanation: The formula calculates the exact amount of insulin required to cover the carbohydrates you plan to consume, based on your personal insulin-to-carb ratio.
Details: Proper insulin dosing for carbohydrates is essential for maintaining target blood glucose levels, preventing hyperglycemia after meals, and avoiding hypoglycemia from excessive insulin.
Tips: Enter your carbohydrate intake in grams and your personal insulin-to-carb ratio. Both values must be positive numbers. Consult with your healthcare provider to determine your correct ICR.
Q1: What is a typical insulin-to-carb ratio?
A: ICR varies by individual but typically ranges from 1 unit per 10-15 grams of carbs for adults, and 1 unit per 20-30 grams for children.
Q2: Should I round the insulin dose?
A: It depends on your insulin delivery method. With insulin pumps, you can use precise doses. With pens/syringes, you may need to round to the nearest half or whole unit.
Q3: Does this account for current blood glucose levels?
A: No, this calculation only covers carbohydrates. You may need additional correction insulin if your blood glucose is above target before the meal.
Q4: How often should I adjust my ICR?
A: Work with your healthcare team to adjust your ICR based on regular blood glucose monitoring and pattern management.
Q5: Are there factors that affect carbohydrate absorption?
A: Yes, factors like fat, fiber, protein content, exercise, and timing of insulin administration can affect how carbohydrates are absorbed and metabolized.
