What is the insulin-to-carbohydrate ratio?
The insulin-to-carbohydrate ratio is a formula used to find the amount of insulin you need. This amount is based on how many grams of carbs you eat at a meal or snack. Using the ratio allows you to adjust the amount of insulin you take so you can keep your blood sugar at your target level.
You and your doctor or diabetes educator will find your personal ratio by keeping track of the food you eat and testing your blood sugar level after meals.
Your insulin-to-carbohydrate ratio may change over time. In some people it will change from one meal to the next. For example, you might take 1 unit of insulin for every 10 grams of carbs for lunch but take 1 unit for every 15 grams at dinner.
