Beginner’s Guide to Mealtime Insulin: What, When, and Why
Mealtime insulin plays an important role in managing diabetes for many individuals. It can be used by people with Type 1 and Type 2 diabetes.
To learn more about how mealtime insulin works and how to dose it correctly, read on.
💊What is Mealtime Insulin?
Mealtime insulin, also known as bolus insulin, is used to counteract the carbohydrates consumed during a meal. This type of insulin is typically dosed before your meals. For those with Type 1 diabetes, mealtime insulin is essential from diagnosis because their bodies do not produce any insulin to manage carbohydrate intake. In contrast, the need for mealtime insulin in Type 2 diabetes varies. Some individuals may never require it if their diabetes remains well-controlled. However, if the body stops producing enough insulin to process carbohydrates, they may need to begin using mealtime insulin. A few examples of mealtime/ bolus insulin include: Humalog (insulin lispro) and Novolog (insulin aspart).
💊Best Time to Take Mealtime Insulin
Many people worry about taking their insulin before eating because they fear low blood sugars and they don’t know how their body will respond. However, if you are taking your insulin at the right time and in the right dose, you should not experience low sugars.
The best time to inject your subcutaneous mealtime insulin depends on the type of insulin that you are using. Use the chart below to help you determine when best to take your insulin.
Taking your insulin before meals allows the insulin time to start working and helps prevent post-meal time blood sugar spikes. If you inject your insulin during or after a meal, you may notice an increase in your blood sugar levels because the insulin cannot work as quickly given at the same time as the food intake.
Avoid trying to overcorrect, as this can lead to hypoglycemia once the body adjusts. Always make sure you consult your healthcare provider before trying something new to ensure it suits your individual needs.
Summary
Mealtime insulin is crucial for preventing high blood sugar levels after meals. Understanding the medication you are taking and its importance can help reinforce the need to take it consistently and be compliant. It’s essential to consult with your healthcare provider to determine the best dosing for your specific needs. Taking mealtime insulin at the correct time before eating is vital to avoid post-meal blood sugar spikes and achieve better overall control of your blood sugars.
