The problem is some people do not produce enough insulin and others produce too much. Which leads to the question: How are insulin resistance, pre-diabetes, and diabetes different and yet still part of one another? The main differences and similarities between these three involve insulin and glucose. An insulin resistant person will produce too much insulin because fat, muscle, and liver cells are not processing correctly the insulin cells, and their glucose levels, for the moment, will be within normal range. Two tests are also used for determining if a person has insulin resistance. The euglycemic clamp and a fasting insulin test.
