Diabetes is characterized by elevated levels of sugar or glucose (hyperglycemia) in the blood. This occurs due to the lack of the hormone insulin in type 1 diabetes, and to reduced insulin levels in combination with insulin resistance in type 2 diabetes. A recent review of data supports stricter control of hemoglobin A1C levels (HbA1C) among pediatric patients with T1D. This review was led by Dr. Maria J. Redondo, pediatric endocrinologist at Texas Children’s Hospital and professor at Baylor College of Medicine, in collaboration with Dr. Sarah Lyons, pediatric endocrinologist at Texas Children’s and assistant professor at Baylor College of Medicine, along with other leading endocrinologists and diabetes experts across the U.S.
