The Felt Sense of "Insulin on Board" (IOB): Understanding and Managing Your Body's Response

The felt sense of "Insulin on Board" (IOB) is a crucial concept for individuals managing their blood sugar levels, particularly those with diabetes or prediabetes. It refers to the amount of insulin that is actively working in your bloodstream to lower your blood sugar levels. Understanding and managing IOB can help you take control of your blood sugar levels and make informed decisions about your diet, exercise, and medication.

What is IOB and Why is it Important?

IOB is a measure of the amount of insulin that is currently working in your body to lower your blood sugar levels. It's an important concept because it helps you understand how your body is responding to insulin and how to manage your blood sugar levels effectively. When you eat, your body releases insulin to help your cells absorb glucose from your bloodstream. The amount of insulin that is working in your body at any given time is your IOB.
