Diabetes is a result of the insufficient production what?

The correct answer is: Insulin.

Diabetes is a chronic condition that affects the body's ability to turn food into energy. The most common type of diabetes is type 2 diabetes, which is caused by the body's inability to produce enough insulin or to use insulin effectively. Insulin is a hormone that is produced by the pancreas and is necessary for the body to take in glucose from the blood and use it for energy. When the body does not produce enough insulin or does not use it effectively, glucose can build up in the blood, leading to diabetes.
