Using Meal-Based Self-Monitoring Blood Glucose (SMBG) Data to Guide Dietary Recommendations in Patients With DiabetesFrom the Sansum Diabetes Research Institute, Santa Barbara, California. Correspondence to Lois Jovanovic, MD, MACE, Sansum Diabetes Research Institute, 2219 Bath Street, Santa Barbara, CA 93105 (ljovanovic{at}sansum.org). The purpose of this article is to describe how self-monitoring of blood glucose (SMBG) data is a useful tool for identifying and managing postprandial hyperglycemia (PPHG). PPHG and postprandial glucose excursions occur frequently in patients with diabetes even when hemoglobin A1C is controlled below 7.0%, and convey increased risk of cardiovascular morbidity and mortality. Consequently, effective management of diabetes must include control of postprandial glucose levels. Postprandial plasma glucose (PPG) depends on the composition of meals, specifically the amount of carbohydrates. Reduced-carbohydrate diets offer short-term improvements in glycemic control and other metabolic parameters, but await the support of long-term efficacy and safety studies. Glucose profiling and paired-meal SMBG are useful tools for detecting PPHG and glucose excursions. They provide immediate feedback to patients on the effect of foods and meals, thereby allowing appropriate food and medication adjustments to improve postprandial glycemic control.
