Type-1 diabetes is known as insulin-dependent diabetes
Insulin dose calculation determines the insulin units needed
The more carbohydrate you eat, the more insulin you require
Diabetes is more common in low and middle-income countries with around 422 million cases worldwide, according to the World Health Organization . The most common diabetes, Type 2, occurs when your body fails to use insulin effectively. Type 1 diabetes or insulin-dependent diabetes, on the other hand, is a chronic condition where your body doesn’t produce enough insulin.
In this case, your diabetic blood sugar levels are likely to be unpredictable. This is when doctors may recommend insulin doses to help you maintain your blood sugar levels. You may be either on a fixed insulin dose therapy or a flexible dose therapy as advised . Knowing how to calculate how much insulin to take will help you manage diabetes better.
Read on to know why and how to calculate insulin dose as a diabetic or a caregiver to a diabetic.
Insulin dose calculation helps you manage your blood sugar level efficiently. Knowing the insulin on board and the dose you need helps you in many ways. You can ascertain if you need to increase insulin to level off high blood sugar or to reduce the carbohydrates that you eat. It helps you keep track of certain activities too, such as knowing if it is safe to take a walk without your blood sugar going low or if you should have something to eat before bed.

You can use certain apps and an online insulin calculator or insulin correction dose calculator to compute and keep track of the required rapid-acting insulin dose. However, you can also calculate the units for carbohydrate, blood sugar correction, and total meal insulin dose by using manual formulae.
The insulin to carbohydrate ratio determines the bolus dose for food coverage. It depicts how much carbohydrate is disposed of by 1 unit of insulin. The actual units of insulin depend on a person’s sensitivity to it. Usually, one unit of such a dose disposes of 12-15 grams of CHO or can even range from 4 to 30 grams based on sensitivity.
For carbohydrate coverage insulin dose calculation, use the formula below.
CHO insulin dose = Total grams of CHO in the meal / grams of CHO disposed of by 1 unit of insulin
For example, assume you will consume 80 gram of carbohydrates in your meal and your insulin ratio is 1:10.
CHO insulin dose = 80 gram / 10 = 8 units
Thus, you will need 8 units of insulin to dispose of the carbohydrates.
This refers to the amount of rapid-acting insulin units required to drop a high blood sugar level. Normally, one unit of insulin drops blood sugar by 50 mg/dl. However, it can range from 15 to 100 mg/dl depending on a person’s sensitivity to insulin.
For high blood sugar correction insulin dose calculation, apply the following formula.
High blood sugar correction dose = Target blood sugar – actual blood sugar / correction factor
For example, assume you require 1 unit of insulin to drop 50 mg/dl of blood sugar. Thus, your correction factor is 50 points. Your blood sugar before a meal is 230 mg/dl and your target is 130 mg/dl. Fill these figures in the formula to arrive at the required blood sugar correction dose.
Correction dose = 230 – 130 / 50 = 2 units
Thus, you require 2 units of high blood sugar correction dose to reach the target level.
Add the carbohydrate coverage dose and high blood sugar correction dose to get the total mealtime dose.
Total meal insulin = carbohydrate coverage dose + high sugar correction dose
For example, consider that you require 8 units of rapid-acting insulin for carbohydrate coverage dose and 2 units of insulin for high blood sugar level correction dose. Now, enter the data into the formula for total meal insulin dose calculation.
Total meal insulin dose = 8 units + 2 units = 10 units.
Thus, your total meal insulin dose will be 10 units of rapid-acting insulin.
Around 40-50% of the total daily insulin is administered to replace insulin overnight and 50-60% is for carbohydrate coverage and high blood sugar correction .
Many people suffer from insulin hormone deficiency due to diabetes. If not treated, this can lead to deadly consequences. Patients are injected insulin doses daily for their body to function properly. However, you may wonder if it is possible to survive without insulin if you don’t get access to it. The conventional thought is that your body can go without insulin for 3 to 4 days on average. After that, you may face severe complications. However, it is better to consult with a doctor as every person’s sensitivity to insulin differs. Also, researchers are now successfully identifying and administering alternatives to insulin .
