Our Results

Our diabetic patients' success rivals that of the results seen at The Cleveland Clinic, one of the nation's foremost centers for diabetes care. One indicator of diabetes control is the hemoglobin A1c, which is a 3 month average of blood glucose, in percentage form, with an A1c less than 7.0% considered favorable glucose control.

In a recent analysis, 45% of our patients have achieved this goal A1c of less than 7%, compared to 35% of patients at The Cleveland Clinic. The Cleveland Clinic mean baseline A1c was 7.3%, and our patients' baseline A1c is 7.5%. 

As of February 2016, there has been a 11.8% improvement for all patients from the patient’s first A1c to the most recent.

Stay tuned for more results!

February 2016


Oklahoma has one of the highest rates of diagnosed diabetes in the U.S.  The national incidence of diabetes is 10% of the U.S. population and Oklahoma's incidence of diabetes is 13.3% of the state's population. 


Do Dr. Kipgen and Dr. Hummer make a difference in the health outcomes for our patients?  We analyzed the A1c levels of patients over the past year.  The group's A1c improved by 11.8% and the patients lost weight as well.  We know from an article in Diabetes Care that a 1% reduction in A1c levels can reduce microvascular complications by 30% or more.  


We take a comprehensive, personalized approach to EVERY patient.  We use many diagnostic tests including EKGs and Continuous Glucose Monitoring.  We offer a complete diabetic education program including nutrition and basic health classes.  By sharing the results of these tests with every patient, in conjunction with a very specific medical treatment plan, we have found that our patients become more successful at managing their health.  By providing you with knowledge, resources, and an individualized treatment plan, we hope to empower you to better health.
