# Readers ask: How To Calculate An Insulin To Carb Ratio In Type 2 Diabetes?

## How do you calculate insulin to carb ratio?

Practice using an insulin-to-carb ratio

1. Divide your total grams of carbohydrate by your ratio of 10. So 55 ÷ 10 = 5.5.
2. Your breakfast dose will be 5.5 units of rapid-acting insulin.

## How many units of insulin should I take per carb?

You will need 6 units of rapid acting insulin to cover the carbohydrate.

## How do I calculate how much insulin I need?

Divide the total carbohydrates by the insulin to carbohydrate ratio. The result is the amount of insulin units needed. Visit choa.org/diabetes for additional copies. Add the number of units needed for food to the number of units needed to correct blood sugar to get your total dose of insulin (Humalog/Novolog/Apidra).

## How much insulin do I need for 60 carbs?

– For example, if your carb factor is 15 and you plan to eat 60 grams of carbohydrates, your bolus should be 4 units (60 ÷ 15).

## How much does 1 unit of insulin bring down blood sugar?

One unit of insulin should cause your blood sugar level to drop 30 to 50 mg per dL, but you may need more insulin to get the same effect.

## What is the 500 rule in diabetes?

Use the 500 Rule to estimate insulin-to-carb ratio: 500/TDD = number of carb grams covered by a unit of insulin. Example: 500/50=10; 1unit of insulin will cover about 10 grams of carbohydrate.

## Is 50 units of insulin too much?

It is possible that the “maximum” of 50 units is derived from the technical limitations of the 1/2 mL syringe. The Lantus SoloStar disposable pen has a maximum “dial-able” dose of 80 units. Aside from this technical maximum, there is no mention of a maximum dose in the package insert.

## How many units of insulin per day is normal?

How much insulin do you need? In type 1 diabetes, most people need a total of 0.5 – 0.8 units of insulin per kilogram of body weight each day.

## What is the average carb ratio for a diabetic?

On average, people with diabetes should aim to get about half of their calories from carbs. That means if you normally eat about 1,800 calories a day to maintain a healthy weight, about 800 to 900 calories can come from carbs. At 4 calories per gram, that’s 200–225 carb grams a day.

## What is a typical sliding scale for insulin?

70-139 mg/dL – 0 units 140-180 mg/dL – 3 units subcut 181-240 mg/dL – 4 units subcut 241-300 mg/dL – 6 units subcut 301-350 mg/dL – 8 units subcut 351-400 mg/dL – 10 units subcut If blood glucose is greater than 400 mg/dL, administer 12 units subcut, notify provider, and repeat POC blood sugar check in 1 hour.

## How much insulin do I need Type 2 diabetics take?

To start, however, your doctor may begin by prescribing 0.15 units of insulin per kilogram.

## What is the sliding scale for insulin?

The term “sliding scale” refers to the progressive increase in pre-meal or nighttime insulin doses. The term “sliding scale” refers to the progressive increase in the pre-meal or nighttime insulin dose, based on pre-defined blood glucose ranges. Sliding scale insulin regimens approximate daily insulin requirements.

## How much insulin do I need for 44 carbs?

If our ratio is 1 unit of insulin for every 15 g of carbohydrates, here’s how we’d determine how much insulin is needed to cover the carbs for this meal. 44 g carbohydrates / 15 g carbohydrates (ratio) = 2.9 units of insulin. 2.9 units of insulin are required for this meal.

## How do you calculate carb factor?

To calculate the carb factor for that food, divide the weight (in grams) into the total grams of carbohydrate (total carb ÷ total weight). The number should be less than 1. This is the carb factor for that food.
