Answer:

When you have type 2 diabetes, your body still breaks down carbohydrate from your food and drink and turns it into glucose. The pancreas then responds to this by releasing insulin. But because this insulin can't work properly, your blood sugar levels keep rising. This means more insulin is released.

Step-by-step explanation:

Glucagon increases blood sugar levels, whereas insulin decreases blood sugar levels. If your pancreas doesn't make enough insulin or your body doesn't use it properly, you can have high blood sugar (hyperglycemia), which leads to diabetes.
