Before developing diabetes, a person's blood glucose is still considered normal and average. But the level of insulin can be very high because that person's body is resistant to insulin. This simply means more insulin is needed to keep the glucose level normal. A similar amount of dosage of insulin given to a person with 'T2DM' is not as effective as to a person with 'T1DM'. Unlike type 1, type 2 does not involve the dangerous diabetic ketoacidosis whereby excessive glucose is being produced.
